Extract:
Question 1 of 5
A nurse prepares to administer vancomycin 15 mg/kg/day divided equally every 12 hr. The client weighs 198 lb. How many mg should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: Calculated: 198 lb ÷ 2.2 = 90 kg; 15 mg/kg/day × 90 kg = 1350 mg/day; 1350 ÷ 2 = 675 mg per dose.
Question 2 of 5
A client with hypertension and benign prostate hyperplasia is prescribed doxazosin (Cardura). Which of the following statements below would the nurse emphasize regarding doxazosin (Cardura)?
Correct Answer: B
Rationale: Doxazosin's first-dose hypotension can cause dizziness, so lying down after the initial dose minimizes fall risk.
Question 3 of 5
The nurse is caring for a client who experienced a dry-non productive cough associated with an ACE inhibitor. Which of the following drugs is an alternative to ACE inhibitors?
Correct Answer: A
Rationale: Losartan, an ARB, is an effective alternative to ACE inhibitors, managing hypertension without causing a dry cough, unlike beta-blockers, diuretics, or vasodilators.
Question 4 of 5
A nurse is teaching a client who has angina about nitroglycerin sublingual tablets. Which of the following statements should the nurse include in the teaching?
Correct Answer: D
Rationale: Nitroglycerin dilates blood vessels, increasing cardiac oxygen delivery to relieve angina, its primary therapeutic effect.
Question 5 of 5
A client presents to the emergency healthcare setting and diagnosed with a life-threatening ventricular dysrhythmia. Which of the following medications would the nurse begin to prepare?
Correct Answer: C
Rationale: Procainamide, an antiarrhythmic, is used for ventricular dysrhythmias, unlike atenolol, lisinopril, or adenosine, which target different conditions.
