client with COPD has an acute bronchospasm. The nurse knows the best medication for this emergency situation that is fast-acting is:

Choice A reason: Lasix increases sodium and water excretion, a true diuretic effect. Potassium-sparing is false, per nursing pharmacology. This holds universally, distinctly accurate.

Choice B reason: Lasix depletes potassium, causing hypokalemia; this is true. Potassium-sparing isn’t, per nursing standards. It’s universally recognized, distinctly a known risk.

Choice C reason: Lasix isn’t potassium-sparing; it’s a loop diuretic that loses potassium. This is the exception, per nursing pharmacology. It’s universally distinct, errors in classification.

Choice D reason: Slow position changes prevent Lasix-induced hypotension; this is true. Potassium-sparing is wrong, per nursing standards. It’s universally distinct, a safety measure.

Choice A reason: Hypnotics, like Ambien, induce sleep, matching Seconal’s primary action. This aligns with nursing pharmacology standards for sleep-producing drugs. It’s universally recognized, distinctly applied to facilitate rest effectively in practice.

Choice B reason: Anticoagulants prevent clotting, not induce sleep like hypnotics do. This misidentifies Seconal’s purpose, per nursing standards. It’s a universal error, distinctly unrelated to sleep production in pharmacology.

Choice C reason: Sedatives calm but don’t always induce sleep; hypnotics specifically do. This lacks precision, per nursing pharmacology. It’s universally distinct, missing the sleep focus of Seconal and Ambien.

Choice D reason: Psychotropics affect mood broadly, not just sleep like hypnotics. This errors in specificity, per nursing standards. It’s universally distinct, misaligning with the sleep-inducing role of these drugs.
