Nursing Elites

1. A nurse is caring for a client who is postoperative following a total knee arthroplasty. Which of the following actions should the nurse take?

• A. Place a pillow under the client's knees
• B. Keep the client's legs elevated
• C. Flex the client's knee every 2 hours
• D. Apply heat to the operative knee

Correct answer: B

Rationale: Keeping the client's legs elevated is the appropriate action to prevent venous thromboembolism following a total knee arthroplasty. Elevating the legs helps promote circulation and reduce the risk of blood clots. Placing a pillow under the client's knees may provide comfort but does not address the specific postoperative complication. Flexing the client's knee every 2 hours may be contraindicated as excessive movement can disrupt the surgical site. Applying heat to the operative knee is not recommended immediately postoperatively as it can increase swelling and discomfort.

2. What is the most concerning electrolyte imbalance for a patient receiving digoxin?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hyponatremia
• D. Hypercalcemia

Correct answer: B

Rationale: The correct answer is Hypokalemia. Hypokalemia is the most concerning electrolyte imbalance for a patient receiving digoxin because it can increase the risk of digoxin toxicity. Low potassium levels can potentiate the effects of digoxin on the heart, leading to serious cardiac arrhythmias. Hyperkalemia (Choice A) is not typically associated with digoxin use. Hyponatremia (Choice C) and Hypercalcemia (Choice D) are not directly related to digoxin therapy and do not pose the same risk of toxicity.

3. A nurse is providing discharge teaching to a client who is recovering from a myocardial infarction. Which of the following client statements indicates a need for further teaching?

• A. I will take a daily aspirin to prevent another heart attack.
• B. I should expect to experience chest pain when I exercise.
• C. I will increase my intake of saturated fats.
• D. I will participate in a cardiac rehabilitation program.

Correct answer: C

Rationale: The correct answer is C. Increasing the intake of saturated fats can raise cholesterol levels, which is not recommended after a myocardial infarction. Choices A, B, and D are all appropriate statements indicating a good understanding of post-myocardial infarction care. Taking a daily aspirin can help prevent another heart attack, experiencing chest pain with exercise is a common expectation post-myocardial infarction, and participating in a cardiac rehabilitation program is important for recovery and improving heart health.

4. A nurse is caring for a client who has diaper dermatitis. Which of the following actions should the nurse take?

• A. Apply zinc oxide ointment to the irritated area
• B. Wipe stool from the skin using store-bought baby wipes
• C. Apply talcum powder to the irritated area
• D. Apply a warm compress to the irritated area

Correct answer: A

Rationale: Correct answer: Applying zinc oxide ointment to the irritated area is the most appropriate action for diaper dermatitis. Zinc oxide is a barrier cream that helps protect the skin and promote healing. Choice B is incorrect because using store-bought baby wipes may contain chemicals or fragrances that can further irritate the skin. Choice C is incorrect as talcum powder can also worsen the condition by drying out the skin. Choice D is incorrect because a warm compress is not typically used for diaper dermatitis; it may provide relief for other conditions but is not the best option for diaper dermatitis.

5. A healthcare professional is reviewing the results of an ABG performed on a client with chronic emphysema. Which of the following results suggests the need for further treatment?

• A. PaO2 level of 89 mm Hg
• B. PaCO2 level of 55 mm Hg
• C. HCO3 level of 25 mEq/L
• D. pH level of 7.37

Correct answer: B

Rationale: The correct answer is B. A high PaCO2 level (55 mm Hg) in a client with chronic emphysema suggests respiratory acidosis, which requires further treatment. In chronic emphysema, impaired gas exchange leads to elevated carbon dioxide levels in the blood. Option A (PaO2 level of 89 mm Hg) is near the normal range and does not indicate immediate treatment. Option C (HCO3 level of 25 mEq/L) and option D (pH level of 7.37) are within normal limits and do not suggest the need for further treatment in this context.
