This nurse is caring for a client who is receiving prescribed amlodipine. Which of the following findings would indicate a therapeutic response?
- A. Hemoglobin A1C 5.6% (5.7%)
- B. Blood pressure 119/79 mm Hg
- C. Capillary blood glucose 88 mg/dL (70-110 mg/dL)
- D. Total cholesterol 190 (<200 mg/dL)
Correct Answer: B
Rationale: Amlodipine, a calcium channel blocker, is used to treat hypertension. A blood pressure of 119/79 mm Hg indicates a therapeutic response. Hemoglobin A1C, blood glucose, and cholesterol are not directly affected by amlodipine.

The nurse is caring for a client receiving a continuous infusion of heparin and warfarin. Based on the client's laboratory data, the nurse should take which action? See the image below.
- A. Document the findings
- B. Stop the heparin infusion
- C. Hold future doses of the warfarin
- D. Obtain a prescription of Vitamin K
Correct Answer: B
Rationale: Without specific lab data, stopping heparin is likely if INR is therapeutic (e.g., 2-3 for warfarin), as concurrent heparin and warfarin are typically transitioned. Documenting, holding warfarin, or giving Vitamin K depend on specific INR values.
The nurse is teaching a client who is receiving newly prescribed enalapril. Which of the following information should be a priority for the nurse to include?
- A. This medication may cause you to develop a dry cough.
- B. If you notice swelling of your face, lips, or eyes, report this to your doctor.
- C. You may notice that the taste of foods is different.
- D. You will need to obtain periodic lab work while taking this medication.
Correct Answer: B
Rationale: Enalapril, an ACE inhibitor, can cause angioedema, a potentially life-threatening swelling of the face, lips, or eyes, making this the priority teaching point. Dry cough, taste changes, and lab monitoring are relevant but less urgent.

- A. furosemide
- B. isosorbide
- C. atorvastatin
- D. losartan
Correct Answer: B
Rationale: Sildenafil is contraindicated with nitrates like isosorbide due to the risk of severe hypotension. Furosemide, atorvastatin, and losartan do not have significant interactions with sildenafil.

- A. Prazosin
- B. Naproxen
- C. Verapamil

The nurse is teaching a client about newly prescribed nitroglycerin (NTG) sublingual tablets. Which statement, if made by the client, would indicate a correct understanding of the teaching?
- A. I should allow this tablet to dissolve in my cheek.
- B. I should keep the tablets in the dark bottle.
- C. I should take this medication standing up to prevent indigestion.
- D. I should take one tablet every 7 to 10 minutes if I get chest pain.
Correct Answer: B
Rationale: Nitroglycerin sublingual tablets should be kept in a dark bottle to protect from light degradation, indicating correct understanding. They dissolve under the tongue, not in the cheek, are taken every 5 minutes for chest pain (up to 3 doses), and standing is not required.
