Nursing Elites

1. The client with a history of heart failure is receiving digoxin (Lanoxin). Which electrolyte imbalance increases the risk of digoxin toxicity?

• A. Hypernatremia
• B. Hypercalcemia
• C. Hypokalemia
• D. Hypomagnesemia

Correct answer: C

Rationale: Hypokalemia increases the risk of digoxin toxicity as low potassium levels enhance the effects of digoxin on the heart, leading to toxicity and potential adverse effects. Hypernatremia (Choice A) is not directly associated with an increased risk of digoxin toxicity. Hypercalcemia (Choice B) does not increase the risk of digoxin toxicity. Hypomagnesemia (Choice D) can contribute to digoxin toxicity, but hypokalemia has a more significant impact on increasing the risk.

2. A client with chronic heart failure is being discharged with a prescription for digoxin (Lanoxin). Which instruction should the nurse reinforce?

• A. Take the medication at the same time each day.
• B. Avoid foods high in potassium.
• C. Skip a dose if you feel well.
• D. Take the medication on an empty stomach.

Correct answer: A

Rationale: Taking digoxin at the same time each day is essential to maintain a consistent blood level of the medication. This consistency helps optimize the therapeutic effects of digoxin in managing chronic heart failure. Deviating from the scheduled time could lead to fluctuations in drug levels, affecting its effectiveness and potentially causing harm. Choices B, C, and D are incorrect because avoiding potassium-rich foods, skipping doses when feeling well, and taking the medication on an empty stomach are not relevant or appropriate instructions for a client prescribed digoxin.

3. A client is admitted to the hospital with a venous stasis leg ulcer. The nurse inspects the ulcer expecting to note which observation?

• A. The ulcer has a pale-colored base.
• B. The ulcer is deep, with even edges.
• C. The ulcer has little granulation tissue.
• D. The ulcer has a brownish or 'brawny' appearance.

Correct answer: D

Rationale: When assessing a venous stasis leg ulcer, the nurse should expect to note a brownish or 'brawny' appearance. This discoloration is often due to hemosiderin deposits. The correct answer is not A because venous stasis ulcers typically do not have a pale-colored base. Choice B is incorrect as venous stasis ulcers usually have irregular, shallow edges, not deep and even edges. Choice C is incorrect as venous stasis ulcers often have excess granulation tissue, not little granulation tissue. Recognizing the brownish or 'brawny' appearance is crucial for accurate diagnosis and appropriate treatment of venous stasis leg ulcers.

4. A client admitted with coronary artery disease (CAD) reports dyspnea at rest. What intervention should the nurse prioritize?

• A. Providing a walker to aid in ambulation
• B. Elevating the head of the bed to at least 45 degrees
• C. Performing continuous monitoring of oxygen saturation
• D. Placing an oxygen cannula at the bedside for use if needed

Correct answer: B

Rationale: In a client with coronary artery disease (CAD) experiencing dyspnea at rest, the priority intervention should be to elevate the head of the bed to at least 45 degrees. This position helps reduce the work of breathing, optimizes lung expansion, and can alleviate symptoms of dyspnea by improving oxygenation and ventilation. Providing a walker for ambulation, monitoring oxygen saturation, and having an oxygen cannula at the bedside are important interventions but not the priority when the client is experiencing dyspnea at rest. Elevating the head of the bed is crucial to improve respiratory function and should be prioritized in this situation.

5. A client has a new prescription for prednisone. Which of the following statements should the nurse include in the teaching?

• A. You may experience weight gain.
• B. Increase your intake of vitamin K.
• C. Expect increased urinary output.
• D. You may have dark, tarry stools.

Correct answer: A

Rationale: The correct answer is A: 'You may experience weight gain.' Prednisone commonly causes weight gain as a side effect, so it is important for the client to be aware of this potential outcome. Monitoring weight changes can be essential in managing the medication's effects and overall health. Choices B, C, and D are incorrect. Increasing vitamin K intake is not specifically related to prednisone use. Expecting increased urinary output is not a common side effect of prednisone. Dark, tarry stools are more commonly associated with gastrointestinal bleeding rather than prednisone use.
