Nursing Elites

1. A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which finding indicates that the treatment is effective?

• A. Potassium level of 4.0 mEq/L.
• B. Blood glucose level of 180 mg/dL.
• C. Urine output of 50 mL/hour.
• D. Absence of ketones in the urine.

Correct answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.

2. The nurse is caring for a client who requires a mechanical ventilator for breathing. The high-pressure alarm goes off on the ventilator. What is the first action the nurse should perform?

• A. Disconnect the client from the ventilator and use a manual resuscitation bag
• B. Perform a quick assessment of the client's condition
• C. Call the respiratory therapist for help
• D. Press the alarm reset button on the ventilator

Correct answer: B

Rationale: The correct answer is to perform a quick assessment of the client's condition when the high-pressure alarm goes off on the ventilator. This assessment is crucial to determine the cause of the alarm and the client's current status. Option A is incorrect because disconnecting the client from the ventilator without assessing the situation can be harmful. Option C is incorrect as the nurse should first assess the client before seeking additional help. Option D is incorrect because resetting the alarm without understanding the underlying issue may lead to potential risks to the client.

3. While caring for a client's postoperative dressing, the nurse observes purulent drainage at the wound. Before reporting this finding to the healthcare provider, the nurse should review which of the client's laboratory values?

• A. White blood cell count
• B. Hemoglobin
• C. Serum creatinine
• D. Culture for sensitive organisms

Correct answer: D

Rationale: Purulent drainage suggests an infection at the wound site. Reviewing the culture and sensitivity results will guide appropriate antibiotic treatment by identifying the causative organisms and their antibiotic sensitivities. Elevated white blood cells indicate infection but do not specify the organism. Creatinine and hemoglobin values are unrelated to wound infections.

4. A client with hypertension is prescribed a thiazide diuretic. What dietary recommendation should the nurse make?

• A. Encourage a diet low in carbohydrates and fats.
• B. Avoid foods high in vitamin K, such as spinach and kale.
• C. Increase salt intake to prevent dehydration.
• D. Eat potassium-rich foods like bananas and oranges.

Correct answer: D

Rationale: The correct answer is D: 'Eat potassium-rich foods like bananas and oranges.' Thiazide diuretics can lead to potassium loss, so it is essential for clients to consume potassium-rich foods to maintain adequate levels. Choice A is incorrect because focusing solely on low carbohydrates and fats does not address the specific issue of potassium loss. Choice B is unrelated as vitamin K content is not a concern with thiazide diuretics. Choice C is incorrect as increasing salt intake would exacerbate hypertension and not prevent dehydration.

5. After repositioning an immobile client, the nurse observes an area of hyperemia. What action should the nurse take to assess for blanching?

• A. Document the presence in the client’s record.
• B. Apply light pressure over the area.
• C. Apply heat to the area and reassess in 30 minutes.
• D. Apply cold compresses to reduce the redness.

Correct answer: B

Rationale: The correct action for the nurse to take to assess for blanching in an area of hyperemia is to apply light pressure over the area. Blanching is the temporary whitening of the skin when pressure is applied and then released, indicating that the blood flow is returning to the area. Applying light pressure helps in determining if the hyperemic area blanches, ensuring that blood flow is adequate. Choices A, C, and D are incorrect because documenting findings, applying heat, or using cold compresses are not appropriate actions for assessing blanching in an area of hyperemia.
