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: Water isn’t an electrolyte; diuretics primarily deplete potassium levels. This misidentifies the focus, per nursing pharmacology. It’s a universal error, distinctly irrelevant to electrolyte monitoring in diuretic therapy.

Choice B reason: Diuretics like furosemide often cause potassium loss, risking arrhythmias. Monitoring is critical, per nursing standards. It’s universally recognized, distinctly essential for safe management of diuretic effects.

Choice C reason: Magnesium can shift, but potassium is the primary concern with diuretics. This is secondary, per nursing pharmacology. It’s universally distinct, less critical than potassium in routine monitoring.

Choice D reason: Calcium isn’t typically depleted by diuretics; potassium is key. This errors in priority, per nursing standards. It’s universally distinct, missing the main electrolyte risk in diuretic use.

Choice A reason: Soy lacks iodine link to contrast media allergies. Shellfish correlates instead. This errors per nursing pharmacology. It’s universally distinct, unrelated.

Choice B reason: Shellfish allergies tie to iodine, common in contrast media. This matches nursing pharmacology standards. It’s universally recognized, distinctly accurate.

Choice C reason: Acidic fruits don’t connect to contrast media reactions. Shellfish does instead. This misaligns with nursing standards. It’s universally distinct, irrelevant.

Choice D reason: Shellfish is linked, not none; this is incorrect. This errors per nursing pharmacology. It’s universally distinct, missing the known allergy.
