Nursing Elites

1. What lab value should be prioritized in a patient with HIV?

• A. CD4 T-cell count below 180 cells/mm3
• B. White blood cell count
• C. Serum albumin levels
• D. Hemoglobin levels

Correct answer: A

Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV as it indicates the level of immunocompromise. A count below 180 cells/mm3 signifies severe immunocompromise and an increased risk of opportunistic infections. Choices B, C, and D are not the priority lab values in HIV management. While white blood cell count, serum albumin levels, and hemoglobin levels are important, they do not directly reflect the immune status and progression of HIV as the CD4 T-cell count does.

2. What is a characteristic sign of hypokalemia on an ECG?

• A. Flattened T waves
• B. ST elevation
• C. Prominent U waves
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.

3. A nurse is reviewing the medical record of a client who has unstable angina. Which of the following findings should the nurse report to the provider?

• A. Breath sounds
• B. Temperature
• C. Blood pressure
• D. Creatine kinase

Correct answer: A

Rationale: The correct answer is A: Breath sounds. When caring for a client with unstable angina, changes in breath sounds could indicate left ventricular failure and pulmonary edema due to decreased cardiac output and reduced cardiac perfusion. Reporting any abnormalities in breath sounds promptly to the provider is crucial to prevent further complications. Choices B, C, and D are not directly related to the immediate management of unstable angina. Temperature, blood pressure, and creatine kinase levels are important parameters to monitor but are not the priority in this situation.

4. What teaching should be provided to a patient after cataract surgery?

• A. Avoid NSAIDs
• B. Avoid bright lights
• C. Wear dark glasses while outdoors
• D. Use warm compresses

Correct answer: A

Rationale: The correct teaching to provide to a patient after cataract surgery is to avoid NSAIDs. NSAIDs should be avoided to reduce the risk of bleeding post-surgery. Choices B, C, and D are not directly related to post-cataract surgery care. Avoiding bright lights and wearing dark glasses while outdoors may be beneficial for eye comfort but are not specific postoperative instructions. Using warm compresses is also not a standard teaching after cataract surgery.

5. What should the nurse do when continuous bubbling is seen in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Clamp the chest tube
• C. Replace the chest tube
• D. Continue monitoring the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the nurse should tighten the connections of the chest tube system. This action can often resolve an air leak causing the continuous bubbling. Clamping the chest tube or replacing it would not address the underlying issue of an air leak and may lead to complications. Continuing to monitor the chest tube without taking corrective action may result in the deterioration of the patient's condition.
