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 are the expected signs of compartment syndrome?

A. Unrelieved pain, pallor, and pulselessness
B. Fever, swelling, and redness
C. Muscle cramps and weakness
D. Redness and itching

Correct answer: A

Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. Compartment syndrome is characterized by increased pressure within a muscle compartment, leading to inadequate blood supply. This results in severe pain that is unrelieved by rest or medication, pallor due to compromised blood flow, and pulselessness as a late sign of severe ischemia. Choices B, C, and D are incorrect. Fever, swelling, and redness are not typical signs of compartment syndrome. Muscle cramps and weakness may occur due to other conditions, but they are not primary indicators of compartment syndrome. Redness and itching are also not commonly associated with compartment syndrome.

3. A nurse is caring for a client who has syndrome of inappropriate antidiuretic hormone (SIADH) and is receiving 3% sodium chloride via continuous IV. Which of the following laboratory findings should the nurse identify as an indication that the SIADH is resolving?

A. Urine specific gravity 1.020
B. Sodium 119 mEq/L
C. BUN 8 mg/dL
D. Calcium 8.7 mg/dL

Correct answer: A

Rationale: A urine specific gravity of 1.020 is within the expected reference range and indicates that the kidneys are appropriately concentrating urine, which is a sign that the syndrome of inappropriate antidiuretic hormone (SIADH) is resolving. A low sodium level (choice B) is associated with SIADH, so a sodium level of 119 mEq/L is not indicative of resolution. BUN (choice C) and calcium levels (choice D) are typically not directly related to SIADH resolution.

4. What dietary recommendation should be given to a patient with GERD?

A. Avoid mint and spicy foods
B. Eat large meals before bedtime
C. Consume liquids with meals
D. Eat three large meals per day

Correct answer: A

Rationale: The correct recommendation for a patient with GERD is to avoid mint and spicy foods. Mint and spicy foods can aggravate GERD symptoms by relaxing the lower esophageal sphincter and increasing stomach acid production, leading to acid reflux. Choices B, C, and D are incorrect. Eating large meals before bedtime can worsen GERD symptoms as lying down can promote acid reflux. Consuming liquids with meals can also exacerbate GERD by increasing stomach distension and pressure on the lower esophageal sphincter. Eating three large meals per day can overload the stomach and trigger acid reflux episodes in patients with GERD.

5. What does continuous bubbling in the water seal chamber of a chest tube indicate?

A. An air leak
B. A blockage in the chest tube
C. Normal chest tube function
D. Malfunction in the drainage system

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber indicates an air leak in the chest tube system. This bubbling occurs when air is escaping through the tube and entering the water seal chamber. Choice B, a blockage in the chest tube, is incorrect as continuous bubbling does not suggest a blockage. Choice C, normal chest tube function, is incorrect because continuous bubbling is not an expected finding in a properly functioning chest tube. Choice D, a malfunction in the drainage system, is incorrect as continuous bubbling specifically points towards an air leak, not a general malfunction.
