1. What does continuous bubbling in the chest tube water seal chamber indicate?

A. An air leak
B. Normal chest tube function
C. A blocked chest tube
D. Continuous drainage from the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber indicates an air leak in the chest tube system. This occurs when air is entering the system from the outside, preventing the lung from fully re-expanding. Choice B is incorrect because continuous bubbling is not a sign of normal chest tube function. Choice C is incorrect because a blocked chest tube would typically exhibit no bubbling or fluctuation in the water seal chamber. Choice D is incorrect as continuous drainage would not cause bubbling in the water seal chamber.

2. What should be the priority action when a patient is admitted with chest pain from acute coronary syndrome?

A. Administer sublingual nitroglycerin
B. Obtain IV access
C. Check cardiac enzymes
D. Administer aspirin

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. This is the priority action in treating chest pain associated with acute coronary syndrome as it helps to dilate blood vessels, improve blood flow to the heart, and reduce cardiac tissue damage. Administering nitroglycerin is crucial in managing the symptoms and potential complications of acute coronary syndrome. Obtaining IV access (Choice B) is important for administering medications and fluids but does not address the immediate symptom of chest pain. Checking cardiac enzymes (Choice C) and administering aspirin (Choice D) are essential steps in the management of acute coronary syndrome, but they should follow the administration of nitroglycerin to address the immediate symptom and improve blood flow to the heart.

3. A nurse is developing a plan of care for a client who will be placed in halo traction following surgical repair of the cervical spine. Which of the following interventions should the nurse include in the plan?

A. Inspect the pin site every 4 hours
B. Monitor the client's skin under the halo vest
C. Ensure two personnel hold the halo device when repositioning the client
D. Apply powder to the client's skin under the vest to decrease itching

Correct answer: B

Rationale: The correct answer is to monitor the client's skin under the halo vest. This is important to assess for signs of skin issues such as excessive sweating, redness, or blistering, which can lead to skin breakdown and infection. Choice A is incorrect because while inspecting the pin site is important, it should be done more frequently than every 4 hours. Choice C is incorrect as the halo device should be supported by the client's body weight, not personnel, when repositioning. Choice D is incorrect because applying powder frequently can increase the risk of skin irritation and infection.

4. What are the expected ECG changes in hypokalemia?

A. Flattened T waves
B. ST elevation
C. Wide QRS complex
D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.

5. 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.
