1. The nurse is caring for a client with a chest tube in place following a pneumothorax. Which assessment finding requires immediate intervention?

A. Oxygen saturation of 94%
B. Crepitus around the insertion site
C. Subcutaneous emphysema
D. Blood pressure of 110/70 mmHg

Correct answer: C

Rationale: Subcutaneous emphysema is the assessment finding that requires immediate intervention in a client with a chest tube following a pneumothorax. Subcutaneous emphysema can indicate a pneumothorax recurrence or air leak, which can compromise respiratory function and lead to serious complications. Oxygen saturation of 94% may be concerning but does not require immediate intervention as it is still within an acceptable range. Crepitus around the insertion site is common after chest tube placement and may not always indicate a problem. A blood pressure of 110/70 mmHg is within normal limits and does not require immediate intervention in this context.

2. The nurse is caring for a client with acute kidney injury (AKI) secondary to gentamicin therapy. The client's serum blood potassium is elevated. Which finding requires immediate action by the nurse?

A. Anuria for the last 12 hours.
B. Tachycardia and hypotension.
C. Decreased urine output.
D. Elevated blood urea nitrogen (BUN) levels.

Correct answer: A

Rationale: The correct answer is A. Anuria for the last 12 hours. Anuria, the absence of urine output, indicates complete kidney failure and is a medical emergency that requires immediate attention. In acute kidney injury (AKI), the kidneys are unable to filter waste from the blood effectively, leading to a buildup of toxins and electrolyte imbalances like elevated blood potassium levels. Tachycardia and hypotension (choice B) can be seen in AKI but do not reflect the urgency of addressing anuria. Decreased urine output (choice C) is concerning but not as critical as the absence of urine production. Elevated blood urea nitrogen (BUN) levels (choice D) are indicative of kidney dysfunction but do not demand immediate action as anuria does.

3. A client with chronic renal failure (CRF) is placed on a protein-restricted diet. Which nutritional goal supports this dietary change?

A. Reduce production of urea nitrogen (BUN)
B. Decrease the risk of hyperkalemia
C. Promote healing of injured nephrons
D. Promote the elimination of albumin

Correct answer: A

Rationale: The correct answer is A: Reduce production of urea nitrogen (BUN). A protein-restricted diet is essential for clients with chronic renal failure to decrease the production of urea nitrogen, as the kidneys cannot effectively excrete it. This helps in managing the accumulation of waste products in the body. Choices B, C, and D are incorrect. Choice B is not directly related to a protein-restricted diet but focuses on managing potassium levels. Choice C is not a direct nutritional goal of a protein-restricted diet but aims at supporting kidney function. Choice D is not a target of a protein-restricted diet but relates more to managing protein loss in the urine.

4. A woman who takes pyridostigmine for myasthenia gravis (MG) arrives at the emergency department complaining of extreme muscle weakness. Her adult daughter tells the nurse that since yesterday her mother has been unable to smile. Which assessment finding warrants immediate intervention by the nurse?

A. Uncontrollable drooling.
B. Inability to raise voice.
C. Tingling of extremities.
D. Eyelid drooping.

Correct answer: A

Rationale: Uncontrollable drooling can be a sign of a myasthenic crisis, which requires immediate medical intervention to prevent respiratory failure. Drooling indicates difficulty in swallowing, which can lead to aspiration and respiratory compromise. Inability to raise voice (choice B) and tingling of extremities (choice C) are not typically associated with myasthenic crisis. Although eyelid drooping (choice D) is a common symptom of myasthenia gravis, it is not as urgent as uncontrollable drooling in indicating a potential crisis.

5. A male client notifies the nurse that he feels short of breath and has chest pressure radiating down his left arm. A STAT 12-lead electrocardiogram (ECG) is obtained and shows ST segment elevation in leads II, III, aVF, and V4R. The nurse collects blood samples and gives a normal saline bolus. What action is most important for the nurse to implement?

A. Obtain the results for STAT serum cardiac biomarkers.
B. Assess for contraindications for thrombolytic therapy.
C. Measure ST-segment height and waveform changes.
D. Transfer for percutaneous coronary intervention (PCI).

Correct answer: B

Rationale: Assessing for contraindications for thrombolytic therapy is crucial as it determines whether the client is a candidate for reperfusion therapy. In this scenario, the client is presenting with symptoms and ECG changes consistent with an acute myocardial infarction (MI). Thrombolytic therapy aims at restoring blood flow to the heart muscle, reducing the size of the infarct. However, it is essential to assess for contraindications such as recent surgery, active bleeding, or a history of stroke to avoid potential complications. Obtaining serum cardiac biomarkers or measuring ST-segment changes are important steps in the diagnosis of MI but are not as time-sensitive as assessing for contraindications to thrombolytic therapy. Transfer for percutaneous coronary intervention (PCI) is a definitive treatment for MI, but assessing for thrombolytic therapy eligibility takes precedence in this acute situation.
