1. The nurse is caring for a client with hypertension who is prescribed a thiazide diuretic. The nurse should check which parameter before administering the medication?
- A. Serum potassium level
- B. Blood pressure
- C. Heart rate
- D. Serum sodium level
Correct answer: B
Rationale: Before administering a thiazide diuretic to a client with hypertension, the nurse should check the blood pressure. Thiazide diuretics are prescribed to lower blood pressure, so assessing the client's blood pressure prior to administration helps to monitor the effectiveness of the medication and to ensure the client's safety. Checking the serum potassium level (Choice A), heart rate (Choice C), or serum sodium level (Choice D) are also important parameters in the care of a client on a thiazide diuretic, but the priority assessment before administering the medication is the blood pressure to evaluate the drug's effectiveness in managing hypertension.
2. A nurse is assessing a client who has a new prescription for enalapril. Which of the following findings is a priority for the nurse to report to the provider?
- A. Frequent urination
- B. Dry cough
- C. Tremors
- D. Dizziness
Correct answer: D
Rationale: The correct answer is D: Dizziness. Dizziness is a sign of hypotension, a potential adverse effect of enalapril. Enalapril is an ACE inhibitor commonly prescribed for hypertension. Hypotension is a serious side effect that can lead to complications such as falls and injuries. Reporting dizziness promptly is crucial to prevent any harm to the client. Choices A, B, and C are not directly associated with enalapril use and are less concerning compared to the potential implications of hypotension indicated by dizziness.
3. After administering nitroglycerin to a client with coronary artery disease (CAD) who reports chest pain, what should be the nurse's next priority action?
- A. Obtain a 12-lead ECG
- B. Monitor the client's blood pressure
- C. Notify the healthcare provider
- D. Administer a second dose of nitroglycerin
Correct answer: B
Rationale: The correct next priority action after administering nitroglycerin to a client with CAD experiencing chest pain is to monitor the client's blood pressure. Nitroglycerin can cause hypotension, so it is crucial to assess and monitor the client's blood pressure for any signs of decreased perfusion or adverse effects. Obtaining a 12-lead ECG may be important but is not the immediate priority. Notifying the healthcare provider and administering a second dose of nitroglycerin should only be considered after ensuring the client's blood pressure is stable.
4. A client has a new prescription for isoniazid. Which of the following instructions should the nurse include?
- A. Take the medication on an empty stomach.
- B. Avoid drinking alcohol.
- C. Take the medication with an antacid.
- D. Increase your intake of leafy green vegetables.
Correct answer: B
Rationale: The correct answer is to instruct the client to avoid drinking alcohol. Isoniazid can cause liver damage, and alcohol consumption can increase this risk. Therefore, it is crucial to avoid alcohol while taking isoniazid to prevent potential liver complications. Choice A is incorrect because isoniazid is typically taken with food to reduce gastrointestinal upset. Choice C is incorrect because antacids can decrease the absorption of isoniazid. Choice D is incorrect as there is no specific recommendation to increase leafy green vegetable intake when taking isoniazid.
5. The nurse is assisting with the care of a client who is on a continuous heparin infusion for deep vein thrombosis (DVT). Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?
- A. Prothrombin time (PT)
- B. Activated partial thromboplastin time (aPTT)
- C. International normalized ratio (INR)
- D. Platelet count
Correct answer: B
Rationale: To evaluate the effectiveness of heparin therapy in a client with DVT, the nurse should monitor the activated partial thromboplastin time (aPTT). The aPTT test helps ensure that the dose of heparin is within the therapeutic range, which is essential for preventing clot formation or excessive bleeding. Monitoring aPTT is crucial in managing patients on heparin therapy to maintain the delicate balance between preventing thrombosis and avoiding hemorrhage. Prothrombin time (PT) and International normalized ratio (INR) are more indicative of warfarin therapy effectiveness, not heparin. Platelet count assesses platelet levels and function, not the effectiveness of heparin therapy for DVT.
