1. What is the purpose of an escharotomy?

A. To relieve pressure and improve circulation in burn injuries
B. To reduce pain in the affected area
C. To remove necrotic tissue from a wound
D. To prevent infection from spreading

Correct answer: A

Rationale: An escharotomy is performed to relieve pressure and improve circulation in areas affected by deep burns. This procedure helps prevent complications such as compartment syndrome by releasing the constricting eschar. Choice B is incorrect because while pain relief may be a secondary outcome of the procedure, the primary purpose is to address pressure and circulation issues. Choice C is incorrect as an escharotomy specifically focuses on releasing pressure, not removing necrotic tissue. Choice D is incorrect as the primary goal of an escharotomy is not to prevent infection but rather to address the immediate issues related to deep burn injuries.

2. What lab value should be prioritized for a patient with HIV?

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

Correct answer: A

Rationale: A CD4 T-cell count below 180 cells/mm3 should be prioritized for a patient with HIV. This value is crucial as it indicates severe immunocompromise in HIV-infected individuals. Monitoring CD4 T-cell count helps assess the status of the immune system and guides treatment decisions. Serum albumin levels (choice B) may reflect the patient's nutritional status and overall health but are not as specific to HIV disease progression. White blood cell count (choice C) and hemoglobin levels (choice D) can be affected by various factors and are not as directly linked to HIV management as the CD4 T-cell count in this context.

3. What are the expected signs in a patient with compartment syndrome?

A. Unrelieved pain, pallor, and pulselessness
B. Fever and infection
C. Localized redness and swelling
D. Loss of sensation in the affected area

Correct answer: A

Rationale: In a patient with compartment syndrome, the classic signs include unrelieved pain, pallor, and pulselessness. These signs indicate compromised circulation and neurovascular function in the affected compartment. Fever and infection (Choice B) are not typical signs of compartment syndrome. Localized redness and swelling (Choice C) can be seen in other conditions like cellulitis but are not specific to compartment syndrome. Loss of sensation in the affected area (Choice D) may occur in some cases but is not as specific or consistent as unrelieved pain, pallor, and pulselessness in diagnosing compartment syndrome.

4. A client is to undergo a liver biopsy. Which of the following instructions should the nurse provide to the client following the procedure?

A. Lie on your left side.
B. Lie on your right side.
C. Increase your fluid intake.
D. Decrease your fluid intake.

Correct answer: B

Rationale: After a liver biopsy, the nurse should instruct the client to lie on the right side. This position helps apply pressure to the biopsy site, promoting hemostasis and reducing the risk of bleeding. Lying on the left side may not provide adequate pressure to the site. Increasing fluid intake is generally beneficial to prevent dehydration and aid in the recovery process, whereas decreasing fluid intake could lead to dehydration and possible complications. Therefore, the correct instruction is to lie on the right side.

5. A client with heart failure is prescribed furosemide 20 mg PO twice daily. Which of the following instructions should the nurse include during discharge teaching?

A. Monitor for increased blood pressure
B. Increase intake of high-potassium foods
C. Expect an increase in swelling in the hands and feet
D. Take the second dose at bedtime

Correct answer: B

Rationale: The correct answer is to instruct the client to increase their intake of high-potassium foods. Furosemide can lead to hypokalemia, a condition of low potassium levels in the blood. Increasing the consumption of high-potassium foods helps prevent this adverse effect. Monitoring for increased blood pressure (choice A) is not directly related to furosemide use. Expecting an increase in swelling (choice C) is incorrect as furosemide is a diuretic that helps reduce swelling. Taking the second dose at bedtime (choice D) is not necessary unless prescribed by the healthcare provider.
