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 prioritized in a patient with HIV?

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

Correct answer: A

Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. In a patient with HIV, monitoring the CD4 T-cell count is crucial as it reflects the status of the immune system. A CD4 T-cell count below 200 cells/mm3 indicates severe immunocompromise and risk of opportunistic infections. Hemoglobin levels (choice B) are important for assessing anemia but do not directly reflect the immune status in HIV patients. Serum albumin levels (choice C) are indicators of nutritional status and inflammation, not specific to HIV disease progression. White blood cell count (choice D) may fluctuate due to various conditions and is not as specific as the CD4 T-cell count in assessing HIV progression.

3. A client is scheduled for an electroencephalogram (EEG) and a nurse is providing teaching. Which of the following statements by the client indicates an understanding of the teaching?

A. I should not wash my hair prior to the procedure.
B. I will receive a sedative 1 hour before the procedure.
C. I should avoid eating prior to the procedure.
D. I will be exposed to flashes of light during the procedure.

Correct answer: D

Rationale: The correct answer is D. The nurse should inform the client that flashes of light or pictures are often used during the procedure to assess the brain's response to stimuli. Choices A, B, and C are incorrect because washing hair, receiving a sedative, and avoiding eating are not directly related to the EEG procedure.

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

A. Administer sublingual nitroglycerin
B. Increase fluids to prevent dehydration
C. Obtain cardiac enzymes
D. Get IV access and auscultate heart sounds

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the priority nursing action for a patient with chest pain and possible acute coronary syndrome. Nitroglycerin helps dilate the blood vessels, improve blood flow to the heart, and reduce cardiac workload. This action aims to relieve chest pain promptly and prevent further cardiac tissue damage. Increasing fluids is not the initial priority for a patient with chest pain and possible acute coronary syndrome. Obtaining cardiac enzymes is important for diagnosis but is not the first action in managing acute symptoms. Getting IV access and auscultating heart sounds are important interventions, but they come after administering sublingual nitroglycerin in the management of acute coronary syndrome.

5. What are the signs of compartment syndrome?

A. Unrelieved pain, pallor, pulselessness
B. Muscle weakness, hyporeflexia
C. Pins-and-needles sensation, swelling
D. Severe swelling and tightness in the affected extremity

Correct answer: A

Rationale: The correct signs of compartment syndrome include unrelieved pain, pallor, and pulselessness due to increased pressure within a muscle compartment. Choice B, muscle weakness, and hyporeflexia are not typical signs of compartment syndrome. Choice C, pins-and-needles sensation and swelling, are not specific signs of compartment syndrome. Choice D, severe swelling and tightness in the affected extremity, could be seen in compartment syndrome but are not the primary signs.
