Correct Answer: A

Rationale: Ondansetron can be administered through two main routes: orally (PO) and intravenously (IV). PO administration involves taking the medication by mouth, typically in the form of tablets or oral dissolving films. IV administration is done by injecting the medication directly into a vein, allowing for rapid onset of action. Ondansetron is not typically administered subcutaneously (C) or intramuscularly (IM).

Correct Answer: C

Rationale: The effect of Beta Blockers is to decrease blood pressure and heart rate. Beta blockers work by blocking the action of adrenaline on beta receptors, leading to decreased heart rate and reduced force of contraction of the heart muscle. This results in a lowering of blood pressure, making beta blockers commonly prescribed for conditions such as hypertension, angina, and heart failure. Additionally, beta blockers are also used to manage certain arrhythmias and prevent heart attacks. Therefore, the correct answer is C - Decreases blood pressure and heart rate.

Correct Answer: B

Rationale: Paradoxical bronchospasm is a rare but serious side effect of Albuterol inhalation, in which the medication actually causes the airways to constrict instead of relax. This can lead to sudden difficulty in breathing, wheezing, and coughing. If a patient experiences paradoxical bronchospasm after taking Albuterol, the nurse should hold the medication and notify a healthcare professional immediately for further evaluation and alternative treatment options. Insomnia, nausea, and headache are known side effects of Albuterol but do not require immediate discontinuation of the medication or notification of a healthcare professional.

Correct Answer: B

Rationale: Hydrocortisone is the main glucocorticoid produced by the adrenal glands. Glucocorticoids are a class of corticosteroid hormones that are involved in regulating metabolism and immune responses. Hydrocortisone, also known as cortisol, plays a crucial role in the body's response to stress, inflammation, and maintaining blood pressure. It is essential for various physiological functions, including regulating blood sugar levels and suppressing the immune system's inflammatory responses. While other glucocorticoids like dexamethasone and prednisone are commonly used in clinical practice for their anti-inflammatory and immunosuppressive effects, hydrocortisone is the primary glucocorticoid naturally produced by the adrenal glands.

Correct Answer: D

Rationale: Vitamin K is a fat-soluble vitamin that is essential for the normal hepatic biosynthesis of factors required for blood clotting. These clotting factors are important for the process of blood coagulation, preventing excessive bleeding when we get injured. Vitamin K plays a crucial role in maintaining proper blood clotting function and a deficiency in this vitamin can lead to increased bleeding tendency.
