The statement "chest compression rate for adult, child and infant cpr is 100 per minute" is false
CPR is a life-saving technique that involves a combination of chest compressions and rescue breaths to restore blood flow and oxygenation to vital organs in the body. The chest compressions are performed by pushing down on the chest with the hands to mimic the pumping action of the heart.
The American Heart Association (AHA) recommends a chest compression rate of 100 to 120 per minute for adult, child, and infant CPR. This rate has been shown to be effective in maintaining blood flow and oxygenation to the body's organs. It is important to follow the recommended compression rate during CPR to increase the chances of survival for the person in need.

RED COMPLEX is associated with __________ and ___________
red complex components (2)
The RED COMPLEX is associated with periodontal disease and includes the red complex components of Porphyromonas gingivalis and Tannerella forsythia.
Periodontal disease is a type of inflammatory condition that affects the tissues that support the teeth, including the gums, ligaments, and bone. It is caused by the buildup of bacterial plaque on the teeth, which triggers an immune response that can damage the surrounding tissues.
One group of bacteria that are strongly associated with periodontal disease is the red complex, which includes Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola. These bacteria are called the "red complex" because they are often found together and are difficult to control, leading to the development of chronic periodontitis.
Porphyromonas gingivalis is a gram-negative anaerobic bacterium that is considered to be a keystone pathogen in periodontal disease. It can produce a range of virulence factors that can damage the host tissues, including enzymes that break down collagen and other proteins.
Tannerella forsythia is another gram-negative anaerobic bacterium that is strongly associated with periodontal disease. It is thought to contribute to the development of chronic inflammation by producing toxins that stimulate the host immune response.

A parasternal heave on physical exam is most commonly associated with?
A parasternal heave on physical exam is commonly associated with right ventricular hypertrophy (RVH)
What medical condition is linked with a parasternal heave during a physical examination?
A parasternal heave on physical exam is commonly associated with right ventricular hypertrophy (RVH), which is a condition where the right ventricle of the heart becomes enlarged.
This is because RVH can cause an enlargement of the right ventricle, which can create a visible and palpable heave or lift on the left side of the sternum.
Other causes of a parasternal heave include left ventricular hypertrophy (LVH), aortic stenosis, pulmonary hypertension, and pulmonary valve stenosis, but RVH is the most common.
This is often due to an increase in pressure or volume overload in the pulmonary circulation, such as in pulmonary hypertension, chronic obstructive pulmonary disease (COPD), or congenital heart defects.
A parasternal heave is typically detected during a physical examination of the chest using palpation or inspection techniques.
Therefore, it is important to perform additional diagnostic tests, such as an electrocardiogram (ECG) or echocardiogram, to determine the underlying cause of the parasternal heave and develop a proper treatment plan.

Does left-sided heart failure increase, decrease, or not affect kidney filtration? Explain.
Left-sided heart failure can affect kidney filtration by decreasing it, when the left side of the heart is unable to pump blood effectively, it leads to a reduction in the blood flow that reaches the kidneys.
As a result, the kidneys receive less oxygen and nutrients, which can impair their normal functioning, this reduced blood flow also means that the glomerular filtration rate (GFR) decreases, leading to a lower rate of filtration in the kidneys. The kidneys play a crucial role in regulating the balance of fluids, electrolytes, and waste products in the body. When kidney filtration is compromised due to left-sided heart failure, waste products can build up in the blood, causing further health complications.
Additionally, the kidneys may struggle to maintain proper fluid balance, leading to fluid retention and swelling (edema). In summary, left-sided heart failure can have a negative impact on kidney filtration by decreasing it. This reduced filtration can lead to the accumulation of waste products in the blood and difficulty maintaining fluid balance, potentially worsening the overall condition of the patient.

What happens when the negative intrapleural pressure is eliminated?
When the negative intrapleural pressure is eliminated, it can lead to a collapse of the lung, also known as pneumothorax.
Intrapleural pressure is the pressure within the pleural cavity, which is the thin fluid-filled space between the lung's outer surface and the inner chest wall. Under normal conditions, the intrapleural pressure is negative, meaning it is lower than the atmospheric pressure. This negative pressure helps keep the lungs expanded and facilitates the process of breathing.
However, if the negative intrapleural pressure is eliminated, the lung loses its ability to remain expanded. This can occur due to a puncture or injury to the chest wall, allowing air to enter the pleural cavity and equalize the pressure. As a result, the lung collapses, and the affected individual may experience difficulty breathing, shortness of breath, and chest pain.
Treatment for pneumothorax typically involves removing the excess air from the pleural cavity, either through a needle or chest tube, to restore the negative intrapleural pressure and re-expand the collapsed lung. In severe cases, surgery may be required. Prompt medical attention is crucial in such cases to ensure proper lung function and recovery.

As a weak base with a pKa of 7.8, lidocaine will have roughly 50% of its molecules in the ionised form (L+) and 50% of its molecules in the nonionized form (L) at a pH equal to its pKa. More lidocaine molecules will exist in the ionised form at pHs above its pKa than in the nonionized form at pHs below its pKa.
The concentration of the ionised and nonionized forms will be equal because the pH of 7.8 and the pKa of lidocaine are same. Therefore, c—an equal mixture of ionised and nonionized forms—is the right response.

TRUE/FALSE. Hold for 12 hours prior to vasodilator stress test
Yes it is True to hold for 12 hours prior to vasodilator stress test.
Is it true to hold for 12 hours prior to vasodilator stress test?It is recommended to hold for 12 hours prior to a vasodilator stress test, also known as a pharmacological stress test.
This type of test is used to evaluate blood flow to the heart in individuals who are unable to exercise or have difficulty with exercise.
The reason for the 12-hour hold is to ensure that there are no confounding factors that could affect the accuracy of the test.
For example, consuming caffeine, nicotine, or certain medications can cause vasoconstriction, which could lead to false-positive results during the test.
Therefore, it is important to avoid these substances and medications for at least 12 hours prior to the test to ensure accurate results.

Does Hypothalamic dysfunction associated w/ Sheehan syndrome?
Sheehan syndrome, caused by severe postpartum hemorrhage, can result in hypothalamic dysfunction and hormonal imbalances.
What can be the consequences of Sheehan syndrome?Yes, hypothalamic dysfunction is commonly associated with Sheehan syndrome. Sheehan syndrome is a condition that occurs in women who experience severe postpartum hemorrhage, leading to ischemic necrosis of the pituitary gland. This can result in hypopituitarism, a condition where the pituitary gland fails to produce one or more hormones.
The hypothalamus, which is closely connected to the pituitary gland, can also be affected in Sheehan syndrome, resulting in hypothalamic dysfunction. The hypothalamus is responsible for regulating a wide range of bodily functions, including body temperature, hunger, and thirst, and hormonal imbalances due to hypothalamic dysfunction can have a wide range of symptoms, including menstrual irregularities, lactation failure, and fatigue.
