The nurse is preparing an educational in-service about valsartan. Which of the following information should the nurse include?
- A. Valsartan blocks the conversion of angiotensin I to angiotensin II.
- B. Valsartan antagonizes angiotensin II receptors.
- C. Valsartan stimulates alpha-2 adrenoceptors in the brainstem.
- D. Valsartan blocks response to beta1- and beta2-adrenergic stimulation.
Correct Answer: B
Rationale: Valsartan, an ARB, antagonizes angiotensin II receptors, reducing blood pressure. It does not block angiotensin conversion, stimulate alpha-2 receptors, or block beta-adrenergic responses.

- A. furosemide
- B. metformin
- C. lisinopril
- D. digoxin
- E. warfarin
- F. metoprolol
Correct Answer: A,C,D,F

The nurse is caring for a client newly diagnosed with an abdominal aortic aneurysm. The nurse should anticipate a prescription for which of the following medications?
- A. naproxen
- B. digoxin
- C. prednisone
- D. atenolol
Correct Answer: D
Rationale: Atenolol, a beta-blocker, is often prescribed to manage blood pressure and reduce stress on the aortic wall in clients with an abdominal aortic aneurysm to prevent rupture. Naproxen (an NSAID), digoxin (a cardiac glycoside), and prednisone (a corticosteroid) are not typically used for this condition.
The nurse has received a prescription for rivaroxaban. The nurse understands that this medication is prescribed to treat which condition?

- C. Congestive Heart Failure

The nurse is teaching a continuing education course regarding cardiovascular medications. It would be appropriate for the nurse to reinforce which condition is a contraindication to administering beta-blockers?
- A. Atrial fibrillation
- B. Myocardial infarction
- C. Congestive heart failure (CHF)
- D. Cardiogenic shock
Correct Answer: D
Rationale: Cardiogenic shock is a contraindication for beta-blockers due to their negative inotropic effects, which can worsen cardiac output. Beta-blockers may be used cautiously in atrial fibrillation, myocardial infarction, or CHF.
