Which order should the nurse question?

  • A. The addition of a loop diuretic with digoxin.
  • B. The addition of a beta blocker with digoxin.
  • C. A digoxin dose of 0.125 mg per day.
  • D. The addition of an ACE inhibitor with digoxin.
Correct Answer: B

Rationale: The correct answer is B: The addition of a beta blocker with digoxin. When combined, beta blockers can enhance the effects of digoxin, leading to an increased risk of bradycardia and heart block. This combination can also exacerbate digoxin toxicity. Therefore, the nurse should question the addition of a beta blocker with digoxin to prevent potential adverse effects.

Incorrect choices:
A: The addition of a loop diuretic with digoxin - Loop diuretics may lead to hypokalemia, which can increase the risk of digoxin toxicity.
C: A digoxin dose of 0.125 mg per day - This is within the recommended dose range for digoxin and does not pose a significant concern.
D: The addition of an ACE inhibitor with digoxin - ACE inhibitors are commonly used in combination with digoxin and do not typically interact negatively.

Which of the following are the reasons a nurse discourages the consumption of alcohol for a client with mitral valve prolapse?

  • A. Tachycardia
  • B. Cinchonism
  • C. Hypertension
  • D. Cardiac stimulation
Correct Answer: D

Rationale: Alcohol can stimulate the heart, exacerbating symptoms in clients with mitral valve prolapse.

Which type of medication is used to reduce the workload on the heart by slowing down the heart rate and lowering blood pressure?

  • A. Beta-blocker
  • B. ACE inhibitor
  • C. Calcium channel blocker
  • D. Diuretic
Correct Answer: A

Rationale: The correct answer is A: Beta-blocker. Beta-blockers reduce the workload on the heart by blocking the action of adrenaline on beta receptors, slowing down heart rate and lowering blood pressure. This helps to decrease the heart's oxygen demand and improve its efficiency. ACE inhibitors (B) work by dilating blood vessels, Calcium channel blockers (C) block calcium entry into cells to relax blood vessels, and Diuretics (D) reduce blood volume by increasing urine output, but they do not specifically target reducing the workload on the heart.

The healthcare provider is monitoring a client on an ACE inhibitor. What lab value is most important to monitor?

  • A. Potassium
  • B. Sodium
  • C. Creatinine
  • D. Calcium
Correct Answer: A

Rationale: The correct answer is A: Potassium. ACE inhibitors can cause hyperkalemia, so monitoring potassium levels is crucial to prevent potential life-threatening complications. High potassium levels can lead to cardiac arrhythmias. Sodium levels are not typically affected by ACE inhibitors. Creatinine is important to monitor for kidney function but not specific to ACE inhibitors. Calcium levels are not directly affected by ACE inhibitors.

Two weeks later, Mr. Cook returns with normal blood pressure readings. Your evaluation of this situation would be

  • A. since his blood pressure is normal, he no longer needs medication
  • B. since his blood pressure recordings are normal, he no longer needs to maintain his prescribed diet
  • C. his medication needs to be adjusted
  • D. the combination of weight loss and medication is effective
Correct Answer: D

Rationale: Weight loss and medication contribute to effective blood pressure control.

What is a chronic condition where the blood pressure in the arteries is persistently elevated, increasing the risk of heart disease and stroke?

  • A. Hypertension
  • B. Hypotension
  • C. Hyperlipidemia
  • D. Hyperglycemia
Correct Answer: A

Rationale: The correct answer is A: Hypertension. Hypertension is characterized by persistently elevated blood pressure, which increases the risk of heart disease and stroke. This condition is commonly referred to as high blood pressure. Hypotension (B) is the opposite, indicating low blood pressure. Hyperlipidemia (C) is high levels of fats in the blood, not directly related to blood pressure. Hyperglycemia (D) is high blood sugar levels, also not directly related to blood pressure. Therefore, based on the definition and associated health risks, A is the correct choice.
