1. What is an escharotomy and when is it performed?

A. A surgical incision to release pressure in burn injuries
B. A procedure to remove dead tissue from wounds
C. An incision to improve circulation in tight skin after burns
D. A procedure to remove excess fluid from the chest

Correct answer: A

Rationale: An escharotomy is a surgical incision made to release pressure in a part of the body that has a deep burn and excessive swelling. This procedure is crucial in preventing further damage due to restricted blood flow and compromised circulation. Choice B is incorrect because it describes debridement, which is the removal of dead tissue from wounds. Choice C is incorrect as it does not specifically address the purpose of relieving pressure in burn injuries. Choice D is incorrect as it describes a procedure more related to thoracentesis, which is the removal of excess fluid from the chest, typically the pleural space.

2. What lab value should be monitored in a patient with HIV?

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

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 CD4 T-cell count below 180 cells/mm3 signifies severe immunosuppression and an increased risk of opportunistic infections. Serum albumin levels (choice B) are important for nutritional status assessment but not specific to HIV monitoring. Hemoglobin levels (choice C) are important for assessing anemia but do not directly reflect HIV disease progression. White blood cell count (choice D) is a general marker of inflammation and infection, but monitoring CD4 T-cell count is more specific and crucial in managing HIV.

3. What are the expected symptoms in a patient with a thrombotic stroke?

A. Gradual loss of function on one side of the body
B. Sudden loss of consciousness
C. Severe headache and confusion
D. Loss of sensation in the affected limb

Correct answer: A

Rationale: A thrombotic stroke typically presents with a gradual loss of function on one side of the body. This gradual onset distinguishes it from a hemorrhagic stroke, which often manifests with sudden and severe symptoms like loss of consciousness (choice B), severe headache and confusion (choice C), or loss of sensation in the affected limb (choice D). Therefore, choices B, C, and D are not typically associated with thrombotic strokes.

4. What is the initial nursing action for a patient with chest pain and acute coronary syndrome?

A. Administer sublingual nitroglycerin
B. Check the patient's urine output
C. Check cardiac enzymes
D. Obtain IV access

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the priority initial action for a patient with chest pain and acute coronary syndrome. Nitroglycerin helps vasodilate coronary arteries, improving blood flow to the heart muscle and reducing chest pain. Checking the patient's urine output (choice B) and cardiac enzymes (choice C) are important assessments but are not the first priority when managing acute chest pain. Obtaining IV access (choice D) is essential for administering medications and fluids, but administering sublingual nitroglycerin takes precedence in the initial management of chest pain in acute coronary syndrome.

5. A nurse is planning care for a group of postoperative clients. Which of the following interventions should the nurse identify as the priority?

A. Administer IV pain medication to a client who reports pain as a 6 on a scale of 0 to 10
B. Administer oxygen to a client who has an oxygen saturation of 91%
C. Instruct a client who is 1 hr postoperative about coughing and deep breathing exercises
D. Initiate an infusion of 0.9% sodium chloride for a client who has just had abdominal surgery

Correct answer: B

Rationale: The priority intervention is administering oxygen. Postoperatively, the client's oxygen saturation should be at or above 95%. Oxygen is essential for tissue perfusion and cellular oxygenation. While managing pain is important, oxygenation takes precedence. Instructing a client about coughing and deep breathing exercises is important for preventing respiratory complications but is not as urgent as addressing low oxygen saturation. Initiating an infusion of 0.9% sodium chloride is a routine postoperative intervention for fluid balance but is not the priority when oxygen saturation is low.
