Smoking cigarettes affects drug metabolism by causing the:

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: Enzyme-stable meds suit oral use; nausea doesn’t allow it. This fits nursing pharmacology standards. It’s universally distinct, a viable condition.

Choice B reason: Nausea/vomiting blocks oral meds; other routes are needed. This is the exception per nursing standards. It’s universally distinct, impractical here.

Choice C reason: Cooperative swallowing enables oral administration; nausea hinders it. This aligns with nursing pharmacology. It’s universally distinct, a suitable scenario.

Choice D reason: Infection allows oral if swallowable; nausea prevents it. This fits nursing standards precisely. It’s universally distinct, not the issue.
