Question 1 of 5
Antilipemic drug therapy is prescribed for a patient, and the nurse is providing instructions to the patient about the medication. Which instructions will the nurse include? (Select all that apply.)
Correct Answer: A
Rationale: A. Limit fluid intake to prevent fluid overload: Antilipemic drugs can sometimes cause fluid retention, so it is important for the patient to limit fluid intake to prevent fluid overload.
Question 2 of 5
A 66-year-old man with a history of recurrent pulmonary infections and hypertension is managed with ethacrynic acid, which controls his hypertension well. He is often hospitalized and placed on gentamicin for his recurrent pulmonary infections. Which of the following adverse effects must the treating physician be keenly aware of?
Correct Answer: B
Rationale: Gentamicin, an aminoglycoside, risks ototoxicity-hearing loss , especially with repeated use. Ethacrynic acid, a loop diuretic, also has ototoxicity potential, compounding risk. Dizziness , nausea , vertigo , and vomiting (E) occur but are less specific. Monitoring hearing is critical in this scenario.
Question 3 of 5
Which of the following drugs is most effective in converting a patient with atrial fibrillation into sinus rhythm?
Correct Answer: B
Rationale: Converting atrial fibrillation (AF) to sinus rhythm requires cardioversion or antiarrhythmics. Digoxin controls rate, not rhythm, ineffective for conversion. Atenolol, a beta-blocker, and diltiazem, a calcium channel blocker, manage rate, not rhythm restoration. Lidocaine treats ventricular arrhythmias. Amiodarone, a class III antiarrhythmic, prolongs repolarization, effectively converting AF to sinus rhythm, especially in acute settings, outperforming others. Its broad-spectrum action is key in AF management, balancing efficacy and safety.
Question 4 of 5
The patient is receiving the benzodiazepine clonazepam (Klonopin) for the treatment of panic attacks. What is an important medication outcome for this patient as it relates to safety?
Correct Answer: D
Rationale: Clonazepam, a benzo, risks withdrawal (e.g., seizures) if stopped abruptly-patients knowing this ensures safe taper, per safety. Stevens-Johnson isn't linked-rash is rare. No diet restrictions apply (unlike MAOIs). Blood work isn't routine for benzos. Abrupt cessation's danger is key, protecting against rebound.
Question 5 of 5
A client has benign prostatic hyperplasia (BPH) and hypertension. Which medication could the client safely receive for hypertension?
Correct Answer: A
Rationale: Terazosin, an alpha-1 blocker, treats hypertension and benign prostatic hyperplasia (BPH) by relaxing vascular and prostate smooth muscle, lowering blood pressure and easing urinary flow. Sildenafil, for erectile dysfunction, doesn't address hypertension or BPH and may drop blood pressure, risking complications. Finasteride shrinks the prostate for BPH but doesn't affect hypertension, missing the dual need. Tamsulosin, also for BPH, can cause hypotension but isn't used routinely for hypertension management. Terazosin's dual efficacy makes it safe and suitable, addressing both conditions without worsening either, unlike alternatives lacking hypertensive benefits or posing risks.
