1. Which of the following types of dressing changes works as a form of wound debridement?

• A. Dry dressing
• B. Transparent dressing
• C. Composite dressing
• D. Wet to dry dressing

Correct answer: D

Rationale: The correct answer is 'Wet to dry dressing.' Wet to dry dressing is a method of wound debridement that involves applying sterile soaked gauze to the wound, allowing it to dry and stick to the wound. When the dressing is removed, it pulls away drainage and debris, aiding in wound debridement. Choice A, 'Dry dressing,' does not actively assist in debridement as it does not collect or remove debris from the wound. Choice B, 'Transparent dressing,' is primarily used for maintaining a moist environment and wound observation, not for debridement. Choice C, 'Composite dressing,' combines multiple layers for different wound care purposes but is not specifically designed for debridement like wet to dry dressing.

2. A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?

• A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
• B. The ventilator coordinates delivered breaths with the client's respiratory efforts
• C. The ventilator provides a supplemental breath for every third breath of the client
• D. The ventilator provides breaths during the expiratory phase of the client's respirations

Correct answer: B

Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.

3. When administering a-interferon and ribavirin (Rebetol) to a patient with chronic hepatitis C, the nurse should monitor for which complication?

• A. Leukopenia.
• B. Hypokalemia.
• C. Polycythemia.
• D. Hypoglycemia.

Correct answer: B

Rationale: When administering a-interferon and ribavirin (Rebetol) for chronic hepatitis C, the nurse should monitor for hypokalemia. This combination therapy is known to cause leukopenia, not polycythemia or hypoglycemia. Hypokalemia is a common electrolyte imbalance that can occur with these medications, making it the correct answer to monitor for in this case.

4. A 1-year-old child is diagnosed with intussusception, and the mother of the child asks the student nurse to describe the disorder. Which statement by the student nurse indicates correct understanding of this disorder?

• A. It is an acute bowel obstruction.
• B. It is a condition that causes an acute inflammatory process in the bowel.
• C. It is a condition in which a distal segment of the bowel prolapses into a proximal segment of the bowel.
• D. It is a condition in which a proximal segment of the bowel prolapses into a distal segment of the bowel.

Correct answer: D

Rationale: Intussusception is a condition in which a proximal segment of the bowel telescopes or prolapses into a distal segment of the bowel. This leads to bowel obstruction and potential ischemia. It is not an acute bowel obstruction, as the obstruction is caused by the telescoping of bowel segments rather than a blockage in the bowel lumen. Intussusception is not primarily an inflammatory process; instead, it is a mechanical issue involving bowel invagination. Choice A is incorrect as it does not accurately describe the pathophysiology of intussusception. Choice C is incorrect because it presents the opposite scenario of what happens in intussusception.

5. The nurse is caring for a 10-year-old on admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is:

• A. Urinary output of 30 ml per hour
• B. No complaints of thirst
• C. Increased hematocrit
• D. Good skin turgor around burn

Correct answer: A

Rationale: For a child of this age, this is adequate output, yet does not suggest overload. Disruption of sodium-ATPase activity presumably causes an intracellular sodium shift which contributes to hypovolemia and cellular edema. Heat injury also initiates the release of inflammatory and vasoactive mediators. These mediators are responsible for local vasoconstriction, systemic vasodilation, and increased transcapillary permeability. Increase in transcapillary permeability results in a rapid transfer of water, inorganic solutes, and plasma proteins between the intravascular and interstitial spaces.
