Which of the following pharmacologic classifications does the drug propranolol fall under?

Correct Answer: A

Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones, specifically by blocking beta receptors. Propranolol, in particular, is a non-selective beta blocker that is commonly used to treat conditions such as hypertension, angina, and arrhythmias. It is also used off-label for anxiety and migraine prevention.

Correct Answer: B

Rationale: Intravesical administration involves the direct instillation of medication into the bladder, which is a common method for treating superficial bladder cancer. This approach allows high concentrations of the drug, such as mitomycin, to come into direct contact with the cancerous cells lining the bladder, minimizing systemic side effects. Intraventricular and intrathecal administrations are used for delivering drugs to the brain and spinal cord, respectively, while intravascular administration refers to intravenous delivery. Intravesical administration is specifically designed for bladder conditions, making it the correct answer.

Correct Answer: B

Rationale: The most common side effect of insulin therapy is hypoglycemia, which occurs when the blood sugar levels drop too low. Insulin helps lower blood sugar levels by promoting the uptake of glucose into cells, but an excessive dose of insulin or changes in diet and physical activity can lead to hypoglycemia. Symptoms of hypoglycemia may include shakiness, sweating, dizziness, confusion, and hunger. It is important for individuals using insulin to be aware of the signs and symptoms of hypoglycemia and be prepared to treat it promptly with fast-acting glucose sources. Regular monitoring of blood sugar levels can help prevent and manage episodes of hypoglycemia.

Correct Answer: B

Rationale: In a patient with a hypertensive emergency, rapid and effective blood pressure reduction is crucial to prevent organ damage. The recommendation for IV administration of antihypertensive medications in this scenario is to titrate the medication to achieve a safe reduction in blood pressure, generally targeting a decrease in mean arterial pressure by no more than 25% within the first hour. The specific medication and infusion rate are dependent on the patient's clinical status and individual factors. Therefore, the maximum dose and duration of infusion must be tailored to the patient's response, with close monitoring by healthcare providers. Hence, determining a fixed time for the maximum dose of the drug to be infused is not appropriate in this critical care scenario.

Correct Answer: B

Rationale: Buspirone, an anxiolytic, requires 2-4 weeks for effect and is dosed thrice daily , showing understanding. Immediate relief is false'it's not a benzo. Alcohol worsens anxiety. It's non-sedating . Thrice-daily dosing aligns with buspirone's steady-state need, key in anxiety where consistency matters, making B the correct statement.
