Angiotension II receptor agents medications

Correct Answer: A

Rationale: Angiotensin II receptor agents, also known as angiotensin II receptor blockers (ARBs), have medication names that typically end in "sartan." Examples of angiotensin II receptor agents include losartan, valsartan, irbesartan, and telmisartan. Therefore, option A, "sar-tan," is the correct answer that matches the medication naming convention for this drug class.

Correct Answer: A

Rationale: A common side effect of Albuterol, a bronchodilator medication used to treat asthma and other respiratory conditions, is paradoxical bronchospasm. This paradoxical reaction leads to an unexpected constriction of the airways instead of the expected relaxation. It can result in increased breathing difficulties and chest tightness, requiring immediate medical attention. Other possible side effects of Albuterol include tremors, palpitations, headache, and nervousness, but paradoxical bronchospasm is notable due to its potential severity and the need for prompt intervention.

Correct Answer: C

Rationale: ACE inhibitors are considered a first-line drug for treating hypertension in many patients. They work by inhibiting the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor, leading to vasodilation and a decrease in blood pressure. ACE inhibitors are well tolerated and have been shown to reduce the risk of cardiovascular events and mortality in patients with hypertension. Other medication classes such as diuretics, alpha blockers, and alpha/beta blockers may also be used in the management of hypertension but ACE inhibitors are often preferred as a first-line therapy due to their efficacy, safety profile, and proven outcomes in hypertension management.

Correct Answer: C

Rationale: The relationship of the blood concentration attained with initial dosing and the dose of drug given is best described by the concept of steady state. Steady state refers to the point at which the rate of drug input (dose) equals the rate of drug elimination, resulting in consistent drug levels in the blood. Achieving steady state typically requires several half-lives of the drug, during which the drug concentration gradually increases with each dose until it stabilizes. The dose of the drug given will influence how quickly steady state is reached and at what concentration the drug will be maintained in the body. Factors such as bioavailability, half-life, volume of distribution, and clearance play important roles in determining the dosage needed to reach and maintain steady state drug levels in the body.
