1. The client with chronic renal failure is on a fluid restriction. Which of the following statements by the client indicates that the teaching has been effective?
- A. I will limit my fluid intake to prevent fluid overload.
- B. I can drink as much fluid as I want as long as I take my medication.
- C. I will skip dialysis sessions if I feel tired.
- D. I will limit my fluid intake to 1 liter per day.
Correct answer: A
Rationale: Choice A is the correct answer because it demonstrates the client's understanding of the need to limit fluid intake to prevent fluid overload, which is crucial in managing chronic renal failure. Adequate fluid restriction is essential to prevent complications such as fluid overload and electrolyte imbalances. Choice B is incorrect as it promotes excessive fluid intake, which can worsen the client's condition by putting additional stress on the kidneys. Choice C is incorrect as skipping dialysis sessions can lead to a buildup of toxins in the body, worsening renal failure and potentially leading to life-threatening complications. Choice D is incorrect because limiting fluid intake to a specific volume may not be appropriate for all clients and can vary depending on individual needs, medical condition, and healthcare provider recommendations.
2. Alteplase recombinant, or tissue plasminogen activator (t-PA), a thrombolytic enzyme, is administered during the first 6 hours after onset of myocardial infarction (MI) to:
- A. Control chest pain.
- B. Reduce coronary artery vasospasm.
- C. Control the arrhythmias associated with MI.
- D. Revascularize the blocked coronary artery.
Correct answer: D
Rationale: Alteplase recombinant, or t-PA, is a thrombolytic enzyme used to dissolve clots and revascularize the blocked coronary artery in patients experiencing a myocardial infarction (MI). Administering t-PA within the first 6 hours of MI onset is crucial to restore blood flow to the affected area and minimize cardiac tissue damage. Therefore, the correct answer is to revascularize the blocked coronary artery. Choices A, B, and C are incorrect because while controlling chest pain, reducing coronary artery vasospasm, and managing arrhythmias are important goals in managing MI, the primary purpose of administering t-PA within the first 6 hours is to restore blood flow by dissolving clots and revascularizing the blocked coronary artery.
3. 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.
4. A client in the intensive care unit is started on continuous venovenous hemofiltration (CVVH). Which finding should prompt immediate action by the nurse?
- A. Blood pressure of 76/58 mm Hg
- B. Sodium level of 138 mEq/L
- C. Potassium level of 5.5 mEq/L
- D. Pulse rate of 90 beats/min
Correct answer: A
Rationale: The correct answer is A: Blood pressure of 76/58 mm Hg. In a client undergoing continuous venovenous hemofiltration (CVVH), hypotension can be a significant concern if replacement fluid does not adequately maintain blood pressure. The nurse should take immediate action to address hypotension to prevent further complications. The sodium level of 138 mEq/L is within normal range, and a potassium level of 5.5 mEq/L, while slightly elevated, may be expected in a patient with acute kidney injury. A pulse rate of 90 beats/min falls within the normal range and does not typically require immediate intervention in this context.
5. The nurse is caring for a patient who is receiving furosemide (Lasix) and an aminoglycoside antibiotic. The nurse will be most concerned if the patient reports which symptom?
- A. Dizziness
- B. Dysuria
- C. Nausea
- D. Tinnitus
Correct answer: D
Rationale: The correct answer is D: Tinnitus. When furosemide and an aminoglycoside antibiotic are used together, there is an increased risk of ototoxicity. Tinnitus, a ringing in the ears, is a common early sign of ototoxicity. Dizziness (choice A) is a common side effect of furosemide but not specifically related to this drug interaction. Dysuria (choice B) is painful urination and is not directly associated with this drug combination. Nausea (choice C) is a common side effect of furosemide but is not specifically indicative of ototoxicity caused by the drug interaction.
