Using the scenario provided, answer the questions that follow. A pharmaceutical company is testing a new drug to treat hypercholesterolemia. The experiment involves 5,000 people who are over the age of 40 and have been diagnosed with hypercholesterolemia in the past one year. All participants have a normal BMI, exercise 2-3x per week, are employed full-time, and do not have any other major underlying health conditions. The population profile includes both genders, is racially and ethnically diverse, and includes participants from five states in the mid-west United States. Half of the participants were given the new drug, the other half were given placebo, and both groups were monitored over the course of two years. All participants were required to eat oatmeal 3x per week. No other dietary modifications were required. Results of the study show that those given the drug had an average of a 20% decrease in blood cholesterol levels, while those that took placebo had a 5% decrease. Side effects of those who took the drug included joint pain, headaches, and stomach pain. Side effects of those taking placebo included headaches.
a. Identify the independent and dependent variables in this experiment. b. The placebo group demonstrated a slight decrease in blood cholesterol and experienced headaches. What may account for this? c. Do you think there was bias in this study? Explain your answer. d. Are the results of this study statistically significant? Explain your answer. e. What question(s) might you ask the person who conducted this study?
a. Independent variable: Drug (new drug or placebo)
Dependent variable: Blood cholesterol levels
b. Possible reasons for placebo group's slight decrease in cholesterol and headaches: Natural variations, placebo effect
c. Potential bias due to lack of blinding: Participants and researchers knew treatment assignment, impacting side effect reporting and cholesterol assessment
d. Statistical significance requires further analysis: Hypothesis testing, p-value calculation

Order: kanamycin 15 mg/kg per day IV in 2 equally divided doses. How many mg will you administer to a patient who weighs 70 kg? 12 Find the BSA of a patient who weighs 80 kg and is 166 cm tall. 13 A patient weighing 100 lb must receive 15 mg/kg PO of a drug. How many 700 mg tablets will you administer? 350 mm
Kanamycin is an antibiotic used to treat severe bacterial infections and tuberculosis. This drug is not the drug of choice. This medication can be taken by mouth, injected into a vein, or injected into a muscle. Kanamycin belongs to the aminoglycoside group which works by inhibiting the production of proteins needed by bacteria to live.
To answer the following questions, you need to use the appropriate mathematical formulas.
Order kanamycin 15 mg/kg per day IV in 2 equally divided doses. How many mg will you administer to a patient who weighs 70 kg?
Answer To calculate the dose of kanamycin to give a patient, you need to multiply the patient's weight by the dose per kilogram. The dose per kilogram is 15 mg/kg per day. So, the total dose given is:
15 mg/kg x 70 kg = 1050 mg per day
Because the dose is divided into two administrations, the dose per administration is:
1050 mg / 2 = 525 mgSo you'd give 525 mg of kanamycin each time.
12 Find the BSA of a patient who weighs 80 kg and is 166 cm tall.
Answer: To calculate the patient's body surface area (BSA), you can use the Du Bois formula. This formula is:
BSA = 0.007184 x (body weight in kg)^0.425 x (height in cm)^0.725
So, the patient's BSA is:
BSA = 0.007184 x (80 kg)^0.425 x (166 cm)^0.725
BSA = 1.86 m^2
13 A patient weighing 100 lb must receive 15 mg/kg PO of a drug. How many 700 mg tablets will you administer?
Answer: To calculate the number of tablets given to a patient, you need to take a few steps:
1) Convert the patient's weight from pounds to kilograms. One pound is equal to 0.4536 kilograms. So, the patient's weight in kilograms is:
100 lb x 0.4536 kg/lb = 45.36 kg
2) Calculate the total dose required by the patient by multiplying the patient's body weight by the dose per kilogram. The dose per kilogram is 15 mg/kg. So, the total dose required is:
15 mg/kg x 45.36 kg = 680.4 mg3) Divide the total dose by the tablet strength to get the number of tablets administered. The strength of the tablets is 700 mg. So, the number of tablets given is:
680.4 mg / 700 mg = 0.97Since it is not possible to give a portion of the tablet, you should round the result up or down according to your doctor's or pharmacist's instructions. For example, if you round up the number of tablets given is:

Both 5 alpha-reductase inhibitors and alpha 1 adrenergic receptor blockers can be used in the treatment of benign prostatic hypertrophy. How does each one work to reduce the symptoms of BPH? Identify priority nursing care/assessments for patients taking these each of these medications References required
Benign prostatic hypertrophy (BPH) is a common condition in elderly men, characterized by noncancerous prostatic enlargement that obstructs the bladder outlet leading to urinary symptoms. Treatment options for BPH include medical management and surgical intervention.
This question seeks to identify how two categories of drugs, 5 alpha-reductase inhibitors and alpha-1-adrenergic receptor blockers, work to relieve BPH symptoms and priority nursing care/assessments for patients taking each medication.
5 alpha-reductase inhibitors 5 alpha-reductase inhibitors work by blocking the enzyme that converts testosterone to dihydrotestosterone (DHT). DHT is responsible for prostatic growth; thus, blocking its production leads to prostate shrinkage. 5 alpha-reductase inhibitors take a long time to work, up to 6 months, but are useful in managing BPH symptoms over time.
Examples of 5 alpha-reductase inhibitors are Finasteride and Dutasteride. Alpha-1-adrenergic receptor blockers Alpha-1-adrenergic receptor blockers work by relaxing the smooth muscles of the prostate gland, bladder neck, and urethra, leading to better urine flow and decreased symptoms of BPH.
Alpha-1-adrenergic receptor blockers are fast-acting, taking effect in days, but do not reduce prostate size. Examples of alpha-1-adrenergic receptor blockers include Prazosin, Terazosin, and Tamsulosin.
Priority nursing care/assessments for patients taking 5 alpha-reductase inhibitors and alpha-1-adrenergic receptor blockers include; Assess baseline blood pressure, as alpha-1-adrenergic receptor blockers may cause orthostatic hypotension and syncope.
Monitor prostate-specific antigen (PSA) levels to monitor prostate size and screen for prostate cancer.
Monitor liver function tests as 5 alpha-reductase inhibitors are metabolized in the liver and may cause liver damage.

Explain why bicarbonate must be conserved rather than reabsorbed
in the kidney.
Bicarbonate, a crucial component of the body's acid-base balance, must be conserved rather than reabsorbed in the kidney to maintain proper physiological functioning.
Acid-Base Balance: Bicarbonate plays a key role in regulating the pH of body fluids. It acts as a buffer, helping to maintain the blood's pH within a narrow range. Conserving bicarbonate ensures that there is an adequate supply available to neutralize excess acid and maintain a balanced pH. Renal Excretion of Acid: The kidneys are responsible for excreting metabolic acids generated in the body.
Acidosis Correction: Conserving bicarbonate allows the kidneys to generate new bicarbonate ions and replenish the body's bicarbonate reserve. This is important in situations where there is an imbalance in acid production or excessive loss of bicarbonate, such as in cases of metabolic acidosis. By conserving bicarbonate, the kidneys can help correct acidosis and restore the acid-base balance.

B. Voltage gated sodium channel
C. Local graded potential
D. Both A and B
E. All of the above
An action potential is initiated by the threshold potential and voltage-gated sodium channels. Option D, "Both A and B" is the correct answer.
An action potential is a quick, transient change in the electrical potential difference between the inside and outside of a neuron's cell membrane. It occurs due to the exchange of ions across the membrane. When the neuron's membrane potential rises beyond a specific threshold, an action potential is produced. An action potential passes along the axon, allowing neurons to communicate with one another.
The axon hillock initiates the action potential in the neurons when the membrane potential reaches a specific value it is called threshold potential. voltage-gated sodium channels on the membrane open at the threshold potential, it allows a massive influx of positively charged sodium ions. positively charged ions influx causes the membrane potential to become more positive and continues the process of depolarization.
Hence, an action potential is initiated by the threshold potential and voltage-gated sodium channels.

The doctor orders 40 meq of IV potassium chloride, but the available amount is 5 meq/hr, with the supply of 40 meq per 100 ml. The nurse will give 0.8 ml of potassium chloride per hour.
Solution: We need to use the formula of intravenous infusion to solve the problem.
IV infusion (ml/hr) = Total volume of IV fluid (ml) × Drip rate (gtts/min) / Time of infusion (min)1000 ml = 1 liter.
We need to use this to convert ml into liters as well.
Therefore,IV infusion (in liters/hr) = Total volume of IV fluid (in liters) × Drip rate (gtts/min) / 60 (min)
First, we need to find out the drip rate. Drip rate = Ordered dose / Hourly volume
Drip rate = 40 meq / 5 meq/hr
Drip rate = 8 gtts/min
Then, we need to find out the total volume of IV fluid.
Total volume of IV fluid = Ordered dose / Available dose
Total volume of IV fluid = 40 meq / 40 meq / 100 ml
Total volume of IV fluid = 100 ml.
Then, we need to find out the IV infusion in liters per hour.
IV infusion (in liters/hr) = Total volume of IV fluid (in liters) × Drip rate (gtts/min) / 60 (min)IV infusion
= 100 ml / 1000 ml × 8 gtts/min / 60 (min)IV infusion

The immunization involved injecting the individual with antibodies against rabies to prompt the body to develop immunity against the virus. This form of immunity is known as acquired active immunity since it involves the individual's immune system producing its antibodies in response to a particular pathogen or vaccine.
When an individual is exposed to an antigen (virus, bacteria, fungi, etc.), the immune system is activated to produce specific antibodies to fight the antigen. After the individual has recovered from the disease, they will have a lasting immunity to the antigen.
The principle behind immunization is to introduce an antigen into the body without causing illness to stimulate the immune system to produce antibodies against the antigen. Vaccines introduce antigens in various forms such as dead or attenuated pathogens, parts of a pathogen, or synthetic antigens that are similar to those of the pathogen.

A family of five lives in a rural community with a population of 750 people. The only store in the town is a convenience store that sells some ready-made pizza and sandwiches along with milk, bread, and numerous prepackaged foods. The nearest large grocery store is 10 miles away. The mother works at the local day care center earning minimum wage, and the father drives a semi-truck delivering grain and similar goods within a 3-hour drive, most days. The family owns a car, however it is not reliable.
The father has diabetes type-2 and high blood pressure. The mother is in good health, and the three children are all overweight.
Discussion question:
a. Based on the family’s circumstance, what are the factors that impact their nutritional needs?
b. How does the type and availability of food impact their health? Consider the children’s nutrition needs and the father’s diabetes.
a. Father's diabetes, children's overweight, limited food choices, distance to store, financial constraints, and father's absence impact their nutritional needs.
b. Limited access to nutritious food and reliance on prepackaged options affect their health.
a. The family's nutritional needs are influenced by several factors:
Father's health conditions: The father's type 2 diabetes and hypertension require careful management of his diet. He needs to focus on controlling his blood sugar levels and blood pressure through specific dietary choices.
Children's weight: The fact that all the children are overweight suggests that their nutritional needs should address weight management. This might involve controlling portion sizes, reducing calorie intake, and promoting healthier food choices.
Limited food choices in the community: Living in a rural community with limited food options means the family has restricted access to a variety of nutritious foods. This limitation can make it difficult to meet their nutritional requirements and maintain a balanced diet.
Distance to the nearest grocery store: The fact that the nearest grocery store is ten miles away presents a challenge in terms of accessibility and convenience. It may be more difficult for the family to access fresh produce and other healthier food options regularly.
Financial constraints: The family's financial situation, with the mother working a minimum wage job and the father often away on business as a truck driver, may pose limitations on their ability to afford nutritious foods. This financial constraint can further impact their ability to meet their nutritional needs adequately.
b. The type and availability of food have a significant impact on the family's health:
Children's nutritional needs: Due to their overweight condition, the children require additional nutrients to support weight management. This includes adequate protein for muscle growth and repair, whole grains for sustained energy, and a variety of fruits and vegetables for essential vitamins and minerals.
Father's diabetes management: The father's diabetes necessitates a low-sugar and low-carbohydrate diet to control his blood sugar levels. This means limiting the intake of sugary and high-carbohydrate foods that can cause spikes in blood glucose.
Limited access to fresh produce: The limited availability of fresh fruits and vegetables in their community can make it challenging for the family to obtain an adequate amount of these nutritious foods. This lack of access to fresh produce may result in a lower intake of essential vitamins, minerals, and dietary fiber.
Reliance on prepackaged foods: If the convenience store primarily offers prepackaged foods, the family may be more inclined to consume processed and unhealthy options. These foods are often high in added sugars, unhealthy fats, and sodium, which can negatively impact their health, especially in the context of the children's weight management and the father's diabetes.
Overall, the family's circumstances create barriers to accessing and maintaining a nutritious diet. The limited food choices, distance to the grocery store, financial constraints, and reliance on prepackaged foods all contribute to potential challenges in meeting their nutritional needs and may have implications for their health.

In general, what would be the order for largest to smallest physiological cross section area between Parallel, Unipennate, Bipennate, and Multipennate fiber arrangements Largest to Smallest= 4. Based on physiological cross section area, compare and contract parallel and pennate muscles. Which type would be able to produce higher velocity of movement? Which type would be better at producing powerful movements and generating force? Which type allow for a greater range of motion? 5. What types of sports or physical activity would a person with more type 1 fibers have an advantage over a person with more type 2 fibers? 6. Which muscle of the hip works to stabilize the pelvis when standing on one leg?
There are two types of parallel fiber arrangement such as strap muscles and fusiform muscle. Whereas, three types of pennate fiber arrangement exist including unipennate muscles, bipennate muscles and multipennate muscles. So far as, the order for the largest to smallest physiological cross-sectional area would be as Multipennate > Bipennate > Unipennate > Parallel.
Strap muscles: Muscles that have long, parallel fibers running the length of the muscle. Example: Sartorius muscle in the thigh.
Fusiform muscles: Muscles that have fibers that run parallel to the long axis of the muscle, tapering at both ends. Example: Biceps brachii muscle in the arm.
Types of pennate fiber arrangement:
Unipennate muscles: Muscles where the muscle fibers are arranged diagonally on only one side of the tendon. Example: Extensor digitorum longus muscle in the leg.
Bipennate muscles: Muscles where the muscle fibers are arranged diagonally on both sides of the tendon. Example: Rectus femoris muscle in the thigh.
Multipennate muscles: Muscles where the muscle fibers are arranged diagonally in multiple directions around multiple tendons. Example: Deltoid muscle in the shoulder.
Comparing parallel and pennate muscles based on physiological cross-sectional area:
Higher velocity of movement.
Producing powerful movements and generating force.
Greater range of motion.
A person with more type 1 fibers (slow-twitch fibers) would have an advantage in endurance activities that require sustained contractions over a long duration.
Examples include long-distance running, cycling, or marathon events. Type 1 fibers are more resistant to fatigue and are efficient in aerobic metabolism.
The muscle of the hip that works to stabilize the pelvis when standing on one leg is the Gluteus Medius muscle.
It is responsible for abduction and medial rotation of the hip and plays a crucial role in maintaining stability and balance during single-leg stance.

Surgical anatomy of the subclavian artery (a.subclavia),
subclavian vein (v.subclavia), the sympathetic trunk (truncus
sympathicus).
The subclavian artery, subclavian vein, and sympathetic trunk are important anatomical structures in the upper body. The subclavian artery supplies blood to the upper limbs.
While the subclavian vein drains blood from the upper limbs. The sympathetic trunk is part of the autonomic nervous system and plays a role in regulating various bodily functions. The subclavian artery is a major blood vessel that arises from the aortic arch in the chest. It travels under the clavicle (collarbone) and gives off various branches to supply blood to the upper limbs, chest wall, and certain structures in the neck and head. The subclavian artery can be divided into three parts based on its relationship to the anterior scalene muscle: the first part is proximal to the muscle, the second part passes behind it, and the third part is distal to the muscle.
The subclavian vein is a large vein located beneath the clavicle and runs parallel to the subclavian artery. It collects deoxygenated blood from the upper limbs and drains into the brachiocephalic vein, which then joins the superior vena cava, a major vein that returns blood to the heart. The subclavian vein is commonly used for central venous access, such as for the administration of medications or fluids, and for hemodialysis.
The sympathetic trunk, also known as the sympathetic chain or truncus sympathies, is part of the sympathetic division of the autonomic nervous system. It is a paired structure consisting of a chain of ganglia (collections of nerve cell bodies) that run vertically on either side of the spinal column. The sympathetic trunk carries sympathetic nerve fibers that control involuntary functions, such as regulating blood pressure, heart rate, and pupil dilation. It also plays a role in the fight-or-flight response and is involved in the body's response to stress.
Understanding the surgical anatomy of the subclavian artery, subclavian vein, and sympathetic trunk is crucial for various medical procedures, including surgeries in the neck and upper chest, central venous catheter placement, and interventions targeting the sympathetic nervous system. It allows healthcare professionals to accurately identify and access these structures, ensuring safe and effective interventions while minimizing the risk of complications.
