Nursing Elites

1. The nurse is caring for a newly admitted patient who will receive digoxin to treat a cardiac dysrhythmia. The patient takes hydrochlorothiazide (HydroDIURIL) and reports regular use of over-the-counter laxatives. Before administering the first dose of digoxin, the nurse will review the patient’s electrolytes with careful attention to the levels of which electrolytes?

• A. Calcium and magnesium
• B. Sodium and calcium
• C. Potassium and chloride
• D. Potassium and magnesium

Correct answer: D

Rationale: Before administering digoxin, the nurse must review the patient's electrolyte levels, focusing on potassium and magnesium. Hypomagnesemia, similar to hypokalemia, can enhance the action of digitalis and lead to digitalis toxicity. Laxatives and diuretics, like hydrochlorothiazide, can deplete both potassium and magnesium. Therefore, monitoring these electrolytes is crucial to prevent potential adverse effects associated with digoxin therapy. Choice A (Calcium and magnesium) is incorrect because calcium levels are not specifically mentioned as crucial for digoxin therapy. Choice B (Sodium and calcium) is incorrect as sodium is not typically monitored in relation to digoxin therapy. Choice C (Potassium and chloride) is incorrect because although potassium is vital, chloride is not typically associated with digoxin therapy.

2. A client has driven himself to the emergency department. He is 50 years old, has a history of hypertension, and informs the nurse that his father died from a heart attack at age 60. The client has indigestion. The nurse connects him to an electrocardiogram monitor and begins administering oxygen at 2 L/min via nasal cannula. What should the nurse do next?

• A. Call for the physician.
• B. Start an IV infusion.
• C. Obtain a portable chest radiograph.
• D. Draw blood for laboratory studies.

Correct answer: B

Rationale: In a client presenting with possible myocardial infarction who is receiving oxygen therapy and cardiac monitoring, the next priority action is to establish IV access by starting an IV infusion. This allows for prompt administration of medications and fluids as needed in the management of acute coronary syndromes. Calling the physician (Choice A) may be necessary but is not the immediate next step. Obtaining a portable chest radiograph (Choice C) may help in further assessment but is not as crucial as establishing IV access. Drawing blood for laboratory studies (Choice D) is important for diagnostic purposes but is not as urgent compared to starting an IV infusion in the setting of a potential myocardial infarction.

3. If a client displays risk factors for coronary artery disease, such as smoking cigarettes, eating a diet high in saturated fat, or leading a sedentary lifestyle, techniques of behavior modification may be used to help the client change the behavior. The nurse can best reinforce new adaptive behaviors by:

• A. Explaining how the risk factor behaviors lead to poor health.
• B. Withholding praise until the new behavior is well established.
• C. Rewarding the client whenever the acceptable behavior is performed.
• D. Instilling mild fear in the client to extinguish the behavior.

Correct answer: C

Rationale: The correct answer is C. A fundamental principle of behavior modification is that behavior that is rewarded is more likely to be continued. Therefore, rewarding the client whenever the acceptable behavior is performed is the best approach to reinforce new adaptive behaviors. Choice A is incorrect because simply explaining how the risk factor behaviors lead to poor health may not be as effective in promoting behavior change compared to positive reinforcement. Choice B is incorrect because withholding praise can hinder progress and motivation for the client. Choice D is incorrect because instilling fear is not a recommended method in behavior modification. It can lead to negative psychological effects and is not a sustainable approach to behavior change.

4. The client who experiences angina has been advised to follow a low-cholesterol diet. Which of the following meals would be best?

• A. Hamburger, salad, and milkshake.
• B. Baked liver, green beans, and coffee.
• C. Spaghetti with tomato sauce, salad, and coffee.
• D. Fried chicken, green beans, and skim milk.

Correct answer: C

Rationale: The best meal option for a client with angina following a low-cholesterol diet is spaghetti with tomato sauce, salad, and coffee. This meal is lower in cholesterol content compared to the other options provided. Hamburger with salad and milkshake, baked liver with green beans and coffee, and fried chicken with green beans and skim milk are higher in cholesterol and may not be suitable for an individual with angina who needs to adhere to a low-cholesterol diet.

5. Which of the following is a common cause of chronic liver disease?

• A. Alcohol abuse.
• B. Hepatitis C infection.
• C. Obesity.
• D. Smoking.

Correct answer: B

Rationale: Hepatitis C infection is a common cause of chronic liver disease due to its long-term effects on the liver. Hepatitis C can lead to liver inflammation, fibrosis, cirrhosis, and even liver cancer. Alcohol abuse can also cause liver damage, but hepatitis C infection is specifically known for its chronic impact on liver health. Obesity and smoking, while detrimental to overall health, are not typically direct causes of chronic liver disease like hepatitis C infection.
