A client with hypertension is prescribed lisinopril (Prinivil). Which statement by the client indicates a need for further teaching?

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: D

Rationale: Sildenafil (Viagra), a phosphodiesterase-5 inhibitor, treats erectile dysfunction (ED) by enhancing penile blood flow, a first-line therapy. Leuprolide suppresses testosterone for prostate cancer, worsening ED. Finasteride and tamsulosin, for BPH, don't target ED and may cause it. Sildenafil's vascular action offers rapid efficacy, making it the go-to choice.

Correct Answer: C

Rationale: Chronic hepatitis C (HCV) treatment targets viral clearance. Pegylated interferon alfa boosts immunity, lamivudine treats HBV, not HCV, so that's incorrect. Adefovir also targets HBV, not HCV. Pegylated interferon alfa with ribavirin, an antiviral, is a historical standard for HCV, enhancing sustained virologic response across genotypes, the recommended combo. Adefovir/lamivudine suits HBV, oseltamivir/zanamivir influenza. Ribavirin's synergy with interferon was key before direct-acting antivirals, effective for this condition.

Correct Answer: A

Rationale: The correct statement by the nurse is to instruct the patient to "stop taking the diuretic for a few days, and then restart it when you feel better." This is because the patient has been experiencing vomiting due to influenza, which can cause dehydration. Continuing the diuretic while experiencing such significant fluid loss can lead to further dehydration and electrolyte imbalances. It is important for the patient to pause the diuretic temporarily to allow the body to recover and then resume once the vomiting has subsided and hydration has improved. It's always best for patients to follow specific instructions given by healthcare providers in such situations.

Correct Answer: B

Rationale: Individual variation-metabolism, weight, genetics-dictates dose differences, a pharmacokinetic truth explaining her higher amount. Female metabolism isn't universally higher. Hormones affect response, but not broadly dose. Body fat impacts distribution, not directly dose here. Uniqueness covers all factors, reassuring and accurate.
