After the nurse teaches the patient with stage 1 hypertension about diet modifications, which diet choice indicates that the teaching has been most effective?
- A. The patient avoids eating nuts or nut butters.
- B. The patient restricts intake of chicken and fish.
- C. The patient drinks low-fat milk with each meal.
- D. The patient has two cups of coffee in the morning.
Correct Answer: C
Rationale: For the prevention of hypertension, the Dietary Approaches to Stop Hypertension(DASH) recommendations include increasing the intake of calcium-rich foods. Caffeine restriction and decreased protein intake are not part of the recommendations. Nuts are high in beneficial nutrients and 4 to 5 servings weekly are recommended in the DASH diet.
The nurse is assessing a patient who has been admitted to the intensive care unit(ICU) with a hypertensive emergency. Which finding is most important to report to the health care provider?
- A. Urine output over 8 hours is 250 mL less than the fluid intake.
- B. The patient cannot move the left arm and leg when asked to do so.
- C. Tremors are noted in the fingers when the patient extends the arms.
- D. The patient complains of a headache with pain at level 8/10(0 to 10 scale).
Correct Answer: B
Rationale: The patient's inability to move the left arm and leg indicates that a hemorrhagic stroke may be occurring and will require immediate action to prevent further neurologic damage. The other clinical manifestations are also likely caused by the hypertension and will require rapid nursing actions, but they do not require action as urgently as the neurologic changes.
Patient presents from having sudden cardiac death with presumed ischemia mediated VT with high grade CAD. Which is best treatment to improve survival?
- A. He needs CABG as a class I B indication
- B. He requires PCI as class I A indication
- C. Global risk reduction to treat inducible ischemia
- D. Treat by symptoms
Correct Answer: A
Rationale: CABG is a class I B indication in this scenario as it addresses the underlying high-grade CAD causing ischemia-mediated ventricular tachycardia, improving survival post-sudden cardiac death.
What is the best action if a client with a history of heart failure prescribed spironolactone and lisinopril has a potassium level of 5.8 mEq/L?
- A. Continue the medications as prescribed.
- B. Notify the healthcare provider immediately.
- C. Administer potassium supplements to stabilize the levels.
- D. Increase the client's fluid intake to dilute the potassium.
Correct Answer: B
Rationale: Spironolactone and lisinopril both increase potassium levels, and a level of 5.8 mEq/L indicates hyperkalemia.
