All the following are true about Lasix (furosemide) except:
It increases water loss by the excretion of sodium
It may cause the patient to become hypokalemic
It is a potassium-sparing diuretic
The nurse should tell the patient to change positions slowly
The Correct Answer is C
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.

Correct Answer is D
Explanation
Choice A reason: Dexamethasone, a steroid, acts slowly, not fast for emergencies. Epinephrine relieves bronchospasm rapidly. This choice errors per nursing standards. It’s universally distinct as unsuitable for acute COPD bronchospasm relief.
Choice B reason: Zafirlukast prevents asthma, not acute bronchospasm; it’s slow-acting. Epinephrine works instantly. This choice misaligns with nursing pharmacology. It’s universally distinct, lacking emergency speed required.
Choice C reason: Oxtriphylline, a bronchodilator, is gradual, not fast-acting. Epinephrine suits emergencies better. This choice errors per nursing standards. It’s universally distinct, ineffective for acute bronchospasm relief.
Choice D reason: Epinephrine dilates bronchi fast, ideal for acute bronchospasm in COPD. It aligns with nursing pharmacology standards. This is universally applied, distinctly effective in emergency respiratory situations.
Correct Answer is A
Explanation
Choice A reason: Bactericidal drugs, like penicillin, directly kill bacteria by disrupting cell walls or metabolism. This matches the question’s definition, ensuring effective infection control. It aligns with nursing pharmacology standards for classifying drugs that destroy bacteria, a critical distinction in treatment, universally recognized and distinctly applied in practice.
Choice B reason: Antineoplastic drugs target cancer cells, not bacteria, focusing on tumor growth inhibition. Destroying bacteria is bactericidal, not antineoplastic. This misidentifies the drug’s purpose, conflicting with nursing pharmacology principles. It’s irrelevant to bacterial destruction, a clear error in classification universally understood in healthcare.
Choice C reason: Analgesics relieve pain, lacking action against bacteria. Bactericidal drugs kill bacteria, not manage symptoms. This choice misaligns with the question’s focus on destruction, per nursing pharmacology standards. It fails to address infection, a distinct mismatch universally recognized in drug categorization.
Choice D reason: Bacteriostatic drugs inhibit bacterial growth, not destroy them outright. Bactericidal agents kill directly, per nursing terminology. This errors by suggesting stasis over destruction, contradicting the question’s intent. It’s a common distinction in pharmacology, universally applied for effective infection management.
