Nursing Elites

1. A nurse is caring for a client who has a prescription for metoprolol. For which of the following findings should the nurse withhold the medication?

• A. Heart rate 56/min.
• B. Oxygen saturation 93%.
• C. Respiratory rate 18/min.
• D. Blood pressure 118/74 mm Hg.

Correct answer: A

Rationale: The correct answer is A: Heart rate 56/min. Metoprolol, a beta blocker, should be withheld if the client's heart rate is below 60/min to prevent further bradycardia. Choices B, C, and D are within normal ranges and do not indicate a need to withhold metoprolol.

2. What is the initial step a nurse should take when irrigating a wound?

• A. Wear sterile gloves while removing the old dressing
• B. Cleanse the wound from the center outward
• C. Apply a warm compress to the wound
• D. Use a 20 mL syringe to irrigate the wound

Correct answer: B

Rationale: The correct first action when irrigating a wound is to cleanse the wound from the center outward. This method helps remove debris and pathogens effectively, reducing the risk of infection. Choice A is incorrect because wearing sterile gloves should be done before starting the wound irrigation but is not the first action in the process. Choice C is incorrect as applying a warm compress is not the initial step in wound irrigation. Choice D is also incorrect as using a syringe to irrigate the wound comes after cleansing the wound.

3. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

4. How should a healthcare professional assess and manage a patient with acute renal failure?

• A. Monitor urine output and administer diuretics
• B. Administer IV fluids and restrict potassium intake
• C. Monitor electrolyte levels and provide dietary education
• D. Administer potassium and restrict fluids

Correct answer: A

Rationale: In acute renal failure, it is crucial to monitor urine output to assess kidney function and fluid balance. Administering diuretics helps manage fluid levels by promoting urine production. Choice B is incorrect because administering IV fluids can worsen fluid overload in renal failure patients, and restricting potassium intake is not typically the initial approach. Choice C is not the primary intervention but is important for long-term management. Choice D is incorrect as administering potassium can be dangerous in renal failure, and restricting fluids can lead to dehydration.

5. A nurse is contributing to the plan of care for a client who has a chest tube connected to a closed drainage system. Which of the following interventions should the nurse include?

• A. Clamp the chest tube
• B. Maintain the drainage below the level of the chest
• C. Elevate the chest tube above chest level
• D. Avoid frequent dressing changes

Correct answer: B

Rationale: The correct intervention for a client with a chest tube connected to a closed drainage system is to maintain the drainage below the level of the chest. This position allows proper drainage of fluids and helps prevent complications such as backflow of blood or fluids into the chest cavity. Clamping the chest tube (Choice A) is incorrect as it can lead to a tension pneumothorax. Elevating the chest tube above chest level (Choice C) is also incorrect because it can impede proper drainage. Avoiding frequent dressing changes (Choice D) is important to prevent introducing infection, but it is not directly related to the position of the drainage system.
