Question 1 of 5
A nurse is caring for a client who is postoperative hip arthroplasty and has a new prescription for enoxaparin 1mg/kg/dose subcutaneous every 12 hr. The client weighs 95 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: Convert pounds to kilograms: 95 lbs ÷ 2.2 lbs/kg = 43.18 kg. Calculate dose: 1 mg/kg × 43.18 kg = 43.18 mg, rounded to 43.2 mg. This ensures accurate dosing for anticoagulation post-surgery.
Question 2 of 5
A nurse is assessing a client who has bradycardia. Which of the following findings should the nurse expect?
Correct Answer: D
Rationale: Lightheadedness occurs due to decreased cardiac output from a slow heart rate in bradycardia. Fluid volume deficit usually causes tachycardia, anxiety increases heart rate, and fever also increases heart rate, not decreases it.
Question 3 of 5
A nurse is establishing health promotion goals for a female client who smokes cigarettes, has hypertension, and has a BMI of 30. Which of the following goals should the nurse include?
Correct Answer: B
Rationale: Regular exercise, such as walking 30 minutes 5 days a week, improves cardiovascular health, aids weight management, and lowers blood pressure. Calcium avoidance is unnecessary, increased calories are counterproductive, and smokeless tobacco still poses risks.
Question 4 of 5
A nurse is educating a client on the use of Pyrazinamide for tuberculosis. Which of the following statements is correct?
Correct Answer: A
Rationale: Pyrazinamide can cause hepatotoxicity, requiring frequent liver function tests. B is related to Ethambutol, C to Isoniazid, and D to Rifampin.
Question 5 of 5
A nurse is monitoring a client who is on telemetry. Which of the following findings on the ECG strip should the nurse recognize as normal sinus rhythm?
Correct Answer: C
Rationale: A QRS duration of 0.06-0.10 seconds is normal and suggests normal conduction through the ventricles in normal sinus rhythm. The P wave should come before the QRS complex, a PR interval >0.20 seconds suggests first-degree AV block, and an inverted T wave suggests myocardial ischemia.
