1. What should the nurse monitor for in a patient with hypokalemia?

A. Monitor for muscle weakness
B. Check deep tendon reflexes (DTRs)
C. Monitor for seizures
D. Monitor for bradycardia

Correct answer: A

Rationale: The correct answer is to monitor for muscle weakness in a patient with hypokalemia. Hypokalemia, which is low potassium levels, can lead to muscle weakness due to its effects on neuromuscular function. Checking deep tendon reflexes (Choice B) is not typically associated with hypokalemia. Seizures (Choice C) are more commonly associated with low calcium levels rather than low potassium levels. Bradycardia (Choice D) is a symptom of hyperkalemia (high potassium levels) rather than hypokalemia.

2. What should a healthcare provider monitor for in a patient with HIV and a CD4 T-cell count below 180 cells/mm3?

A. Monitor for signs of infection
B. Monitor for anemia
C. Monitor for dehydration
D. Monitor for bleeding

Correct answer: A

Rationale: A CD4 T-cell count below 180 cells/mm3 indicates severe immunocompromise in a patient with HIV. Monitoring for signs of infection is crucial because the patient is at high risk of developing opportunistic infections. Anemia (choice B), dehydration (choice C), and bleeding (choice D) are not directly associated with a low CD4 T-cell count in patients with HIV.

3. During an escharotomy on a patient with a burn injury, what is the purpose of this procedure?

A. To release pressure and improve circulation in the affected area
B. To remove dead tissue from the burn area
C. To improve breathing by reducing skin tightness
D. To prevent infection in the burned area

Correct answer: A

Rationale: Corrected Question: During an escharotomy on a patient with a burn injury, the purpose of this procedure is to release pressure and improve circulation in the affected area. This intervention is crucial in severe burns where the formation of eschar (dead tissue) can lead to increased pressure, compromising circulation and potentially causing further tissue damage. Choices B, C, and D are incorrect because escharotomy specifically aims to address pressure and circulation issues in severe burn injuries, rather than removing dead tissue, improving breathing, or preventing infection.

4. What intervention is required 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, tightening the connections of the chest tube system is the appropriate intervention. This action can often resolve an air leak, which is the common cause of continuous bubbling. Clamping the chest tube or replacing it is not recommended as the first-line intervention because it may lead to complications or unnecessary tube changes. Continuing to monitor the chest tube without addressing the air leak would delay necessary corrective action, potentially causing respiratory compromise in the patient. Therefore, tightening the connections of the chest tube system is the most suitable initial step to manage continuous bubbling in the water seal chamber.

5. What are the expected findings in a patient experiencing hypokalemia?

A. Flattened T waves on an ECG
B. Elevated ST segments
C. Prominent U waves
D. Bradycardia

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on an ECG. Hypokalemia is characterized by flattened T waves on an ECG, which is an early indicator of low potassium levels. Elevated ST segments (Choice B) are associated with conditions like myocardial infarction, not hypokalemia. Prominent U waves (Choice C) are typically seen in hypokalemia, but flattened T waves are more specific. Bradycardia (Choice D) can be a manifestation of severe hypokalemia but is not as specific as flattened T waves on an ECG.
