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. The parents of a newborn have been told that their child was born with bladder exstrophy, and the parents ask the nurse about this condition. Which explanation, given by the parents, indicates understanding of this condition?

• A. ''It's a hereditary disorder that occurs in every other generation.''
• B. ''It is caused by the use of medications taken by the mother during pregnancy.''
• C. ''It is a condition in which the urinary bladder is abnormally located in the pelvic cavity.''
• D. ''It's an extrusion of the urinary bladder to the outside of the body through a defect in the lower abdominal wall.''

Correct answer: D

Rationale: Bladder exstrophy is a congenital anomaly characterized by the extrusion of the urinary bladder to the outside of the body through a defect in the lower abdominal wall. The cause of bladder exstrophy is not precisely known, but it is believed to be due to a developmental abnormality during embryogenesis. The condition is more common in male newborns. Choice A is incorrect as bladder exstrophy is not a hereditary disorder that occurs in every other generation. Choice B is incorrect as bladder exstrophy is not caused by medications taken by the mother during pregnancy. Choice C is incorrect as it describes the condition inaccurately; it is not just an abnormal location of the bladder in the pelvic cavity, but rather an extrusion of the bladder outside the body through a defect in the lower abdominal wall.

3. A nurse is caring for a patient with peripheral vascular disease (PVD). The patient complains of burning and tingling of the hands and feet and cannot tolerate touch of any kind. Which of the following is the most likely explanation for these symptoms?

• A. Inadequate tissue perfusion leading to nerve damage.
• B. Fluid overload leading to compression of nerve tissue.
• C. Sensation distortion due to psychiatric disturbance.
• D. Inflammation of the skin on the hands and feet.

Correct answer: A

Rationale: Patients with the peripheral vascular disease often sustain nerve damage as a result of inadequate tissue perfusion. Ischemic rest pain is more worrisome; it refers to pain in the extremity that is due to a combination of PVD and inadequate perfusion. Ischemic rest pain often is exacerbated by poor cardiac output. The condition is often partially or fully relieved by placing the extremity in a dependent position, so that perfusion is enhanced by the effects of gravity.

4. The client is being prepared for insertion of a pulmonary artery catheter (Swan-Ganz catheter). What information does the client need to know about the purpose of this catheter insertion?

• A. Stroke volume
• B. Cardiac output
• C. Venous pressure
• D. Left ventricular functioning

Correct answer: D

Rationale: The correct answer is D: Left ventricular functioning. The purpose of inserting a pulmonary artery catheter is to obtain information about left ventricular functioning when the catheter balloon is inflated. Choices A, B, and C are incorrect because while a pulmonary artery catheter can provide information on stroke volume, cardiac output, and venous pressure, its primary purpose is to assess left ventricular function.

5. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.
