A patient given furosemide for diuresis should have a decrease in what?

Correct Answer: A

Rationale: Furosemide is a loop diuretic commonly used to treat conditions involving edema such as heart failure, liver disease, and kidney disorders. By promoting diuresis (increased urine production), furosemide helps the body eliminate excess fluid, leading to a decrease in edema or swelling. Therefore, a patient given furosemide for diuresis should experience a decrease in edema as the drug acts on the kidneys to increase urine output and eliminate extra fluids from the body.

Correct Answer: A

Rationale: Interferon Alfa-2b, used for hepatitis or cancer, commonly causes flu-like symptoms—dizziness , fatigue , and anorexia —due to its immune-modulating effects. Dizziness reflects CNS impact, often early in therapy, while fatigue and appetite loss stem from systemic inflammation. An itchy rash might suggest hypersensitivity but is less frequent than these systemic effects. The nurse identifies dizziness as a common adverse effect (correct answers: 1, 3, 4), distinguishing it from severe reactions requiring intervention. This aligns with interferon's side effect profile, where patients often report such symptoms within days of starting, necessitating education on management (e.g., rest, hydration). Choice A is a key identifier among expected effects, ensuring appropriate monitoring.

Correct Answer: A

Rationale: Hydrochlorothiazide (HydroDIURIL) is a diuretic that can cause electrolyte imbalances, particularly hypokalemia (low potassium levels). Digitalis (digoxin) is a medication commonly used to treat heart conditions, and its therapeutic effect is dependent on adequate potassium levels. If a patient taking hydrochlorothiazide becomes hypokalemic and then takes digitalis, it can lead to an increased risk of digitalis toxicity. This severe interaction highlights the importance of monitoring potassium levels and potential drug interactions when patients are taking hydrochlorothiazide. Potassium supplements would help counteract the potassium loss caused by hydrochlorothiazide and minimize the risk of interactions with digitalis.

Correct Answer: C

Rationale: Lisinopril, an ACE inhibitor, manages hypertension but requires adherence even if symptoms improve, as stopping abruptly risks rebound hypertension, indicating a teaching gap. Reporting a dry cough is correct due to bradykinin buildup, a common side effect needing evaluation. Rising slowly prevents orthostatic hypotension, a known effect. Avoiding potassium-rich salt substitutes prevents hyperkalemia, as lisinopril inhibits aldosterone. The statement ‘I can stop this medication if I feel better' reflects misunderstanding of chronic disease management, where consistent therapy maintains control, not just symptom relief. Further teaching must emphasize this, aligning with lisinopril's role in long-term vascular protection, making C the statement needing correction.

Correct Answer: C

Rationale: Physostigmine, a cholinesterase inhibitor, lowers IOP in glaucoma by increasing aqueous outflow . It contracts the ciliary muscle, opening the trabecular meshwork. Secretion or synthesis reduction isn't its mechanism. Raising pressure (D, E) contradicts its use. This aids drainage in open-angle glaucoma.
