Nursing Elites

1. A nurse is caring for a client who has a traumatic brain injury. Which of the following findings should indicate to the nurse the need for immediate intervention?

• A. Axillary temperature 37.2°C (99°F)
• B. Apical pulse 100/min
• C. Respiratory rate 30/min
• D. Blood pressure 140/84 mm Hg

Correct answer: C

Rationale: The correct answer is C. The nurse should prioritize airway and breathing in a client with a traumatic brain injury. An increased respiratory rate may indicate CO2 retention, which could lead to increased intracranial pressure. Choice A, axillary temperature 37.2°C (99°F), is within normal range and does not indicate an immediate need for intervention. Choice B, apical pulse 100/min, is slightly elevated but not as critical as respiratory distress in this scenario. Choice D, blood pressure 140/84 mm Hg, is also within normal limits and does not require immediate intervention compared to the respiratory rate.

2. What is the priority dietary modification for a patient with pre-dialysis end-stage kidney disease?

• A. Limit phosphorus intake to 700 mg/day
• B. Increase potassium intake to 3 g/day
• C. Eat three large meals per day
• D. Restrict protein intake to 1 g/kg/day

Correct answer: A

Rationale: The correct answer is A: Limit phosphorus intake to 700 mg/day. In patients with pre-dialysis end-stage kidney disease, restricting phosphorus intake is crucial to manage their condition. Excessive phosphorus can lead to mineral and bone disorders, which are common in kidney disease. Choice B, increasing potassium intake, is not the priority and can be harmful as kidney disease often leads to hyperkalemia. Choice C, eating three large meals per day, is not recommended as smaller, frequent meals are usually better tolerated. Choice D, restricting protein intake to 1 g/kg/day, is important in later stages of kidney disease but is not the priority at the pre-dialysis stage.

3. What ECG changes are expected in hypokalemia?

• A. Flattened T waves on ECG
• B. Prominent U waves on ECG
• C. Widened QRS complexes on ECG
• D. ST elevation on ECG

Correct answer: A

Rationale: In hypokalemia, flattened T waves are a common ECG finding due to the decreased extracellular potassium affecting repolarization. Prominent U waves are typically seen in hypokalemia as well, but flattened T waves are the more specific and early ECG change. Widened QRS complexes are associated with hyperkalemia, not hypokalemia. ST elevation is often seen in conditions like myocardial infarction, pericarditis, or early repolarization syndrome, not specifically in hypokalemia.

4. What intervention is needed when continuous bubbling is observed 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 system
• D. Continue monitoring the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the correct intervention is to tighten the connections of the chest tube system. This can help resolve an air leak that is causing the continuous bubbling. Clamping the chest tube or replacing the entire chest tube system are not appropriate interventions in this scenario. Clamping the tube can lead to a dangerous buildup of pressure, while replacing the chest tube system may not be necessary if the issue can be resolved by simply tightening the connections. Continuing to monitor the chest tube without taking corrective action may lead to complications associated with the air leak.

5. 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.
