1. The nurse is preparing to administer clarithromycin to a patient. When performing a medication history, the nurse learns that the patient takes warfarin to treat atrial fibrillation. The nurse will perform which action?
- A. Ask the provider if azithromycin may be used instead of clarithromycin.
- B. Obtain an order for continuous cardiovascular monitoring.
- C. Request an order for periodic serum warfarin levels.
- D. Withhold the clarithromycin and notify the provider.
Correct answer: C
Rationale: When a patient taking warfarin also needs to receive clarithromycin, it is essential to monitor periodic serum warfarin levels. Macrolides, including clarithromycin, can increase serum levels of drugs like warfarin. Monitoring serum drug levels helps ensure that the patient's warfarin dose can be adjusted, if necessary, to maintain therapeutic levels. Asking about using azithromycin instead is not the most appropriate action in this situation, as all macrolides can interact with warfarin. Continuous cardiovascular monitoring is not indicated solely based on the use of clarithromycin. Withholding the clarithromycin without proper assessment could delay necessary treatment and is not the best initial action.
2. A client with heart disease is on a continuous telemetry monitor and has developed sinus bradycardia. In determining the possible cause of the bradycardia, the nurse assesses the client's medication record. Which medication is most likely the cause of the bradycardia?
- A. Propranolol (Inderal).
- B. Captopril (Capoten).
- C. Furosemide (Lasix).
- D. Dobutamine (Dobutrex).
Correct answer: A
Rationale: Propranolol (Inderal) is a beta-adrenergic blocking agent that acts to decrease heart rate and contractility. Sinus bradycardia is a common side effect of beta blockers due to their negative chronotropic effect on the heart. Captopril (Capoten) is an ACE inhibitor used for hypertension and heart failure, not associated with causing bradycardia. Furosemide (Lasix) is a loop diuretic that can lead to electrolyte imbalances but not commonly linked to bradycardia. Dobutamine (Dobutrex) is a beta-1 adrenergic agonist that increases heart rate and contractility, making it an unlikely cause of bradycardia in this scenario.
3. Which of the following is a common complication of hypertension?
- A. Diabetes.
- B. Heart failure.
- C. Kidney failure.
- D. Stroke.
Correct answer: D
Rationale: The correct answer is D: Stroke. Hypertension can lead to stroke due to the increased pressure on blood vessels in the brain, which can result in reduced blood flow and oxygen to the brain tissue. While choices B (Heart failure) and C (Kidney failure) can be complications of hypertension, they are not as directly associated as stroke. Choice A, Diabetes, is not a direct complication of hypertension but rather a separate condition that can be influenced by various factors. However, stroke is more commonly linked to the increased pressure on blood vessels in the brain in individuals with hypertension.
4. An emergency department nurse assesses a client with kidney trauma and notes that the client’s abdomen is tender and distended, and blood is visible at the urinary meatus. Which prescription should the nurse consult the provider about before implementation?
- A. Assessing vital signs every 15 minutes
- B. Inserting an indwelling urinary catheter
- C. Administering intravenous fluids at 125 mL/hr
- D. Typing and crossmatching for blood products
Correct answer: B
Rationale: In a client with kidney trauma and blood visible at the urinary meatus, inserting a urinary catheter via the urethra should be avoided until further diagnostic studies are completed to prevent potential urethral tears. The nurse should consult the provider about the need for a catheter; if necessary, a suprapubic catheter can be used instead. Assessing vital signs every 15 minutes is important for continuous monitoring of the client's condition. Administering intravenous fluids at 125 mL/hr is crucial to maintain hydration and support kidney function. Typing and crossmatching for blood products is necessary in case the client requires blood transfusion due to potential blood loss from the trauma.
5. What information will the nurse provide when counseling a patient starting a sulfonamide drug for a urinary tract infection?
- A. Drink several quarts of water daily.
- B. If stomach upset occurs, avoid taking antacids.
- C. Limit sun exposure to avoid skin reactions.
- D. Report any sore throat promptly.
Correct answer: A
Rationale: The correct answer is A: Drink several quarts of water daily. This advice aims to prevent crystalluria, a potential side effect of sulfonamide drugs. Option B is incorrect because antacids should not be taken with sulfonamides as they can decrease drug absorption. Option C is incorrect as sulfonamides can increase sensitivity to sunlight, not requiring sun exposure limitations but sun protection measures. Option D is incorrect because a sore throat could indicate a more serious adverse effect and should be promptly reported for evaluation.
