Cardiovascular Assessment Nursing Questions Questions
Question 1 of 5
The charge nurse observes a new registered nurse(RN) doing discharge teaching for a patient with hypertension who has a new prescription for enalapril(Vasotec). Which statement by the new nurse to the patient would require the charge nurse's intervention?
Correct Answer: B
Rationale: The ACE inhibitors cause retention of potassium by the kidney, so hyperkalemia is a possible adverse effect. The other teaching by the new RN is appropriate for a patient with newly diagnosed hypertension who has just started therapy with enalapril.
Question 2 of 5
A 40-year-old male newly diagnosed with hypertension is discussing risk factors with the nurse. The nurse talks about lifestyle changes with the patient and advises that the patient should avoid tobacco use. What is the primary rationale behind that advice to the patient?
Correct Answer: B
Rationale: Smoking increases the risk for heart disease, for which a patient with hypertension is already at an increased risk. Quitting will not necessarily cause hypertension to resolve and smoking does not directly cause ventricular hypertrophy. The association with a sedentary lifestyle is true, but this is not the main rationale for the nurse's advice; the association with heart disease is more salient.

The nurse is screening a number of adults for hypertension. What range of blood pressure is considered normal?
