1. What are the principles of aseptic technique in wound care?

A. Use sterile gloves and a clean dressing
B. Apply a clean dressing using sterile scissors
C. Wash hands thoroughly before applying the dressing
D. Use a clean glove and avoid contact with the wound

Correct answer: A

Rationale: The correct answer is A: 'Use sterile gloves and a clean dressing.' Aseptic technique in wound care requires the use of sterile gloves to prevent infection. Choice B is incorrect as the method of application does not primarily focus on maintaining asepsis. Choice C, while important for infection control, is not specific to aseptic technique in wound care. Choice D is incorrect because using a single clean glove does not ensure the level of sterility needed for aseptic wound care.

2. What are the common signs and symptoms of dehydration in the elderly?

A. Dry mouth, confusion, and decreased skin turgor
B. Increased heart rate and muscle cramps
C. Fever, rapid breathing, and increased urine output
D. Increased thirst and difficulty walking

Correct answer: A

Rationale: Corrected Rationale: Dehydration in the elderly is often signaled by dry mouth, confusion, and decreased skin turgor due to reduced fluid intake. Choice A is the correct answer as these are common signs and symptoms of dehydration in the elderly.\nIncorrect Rationales: Option B (Increased heart rate and muscle cramps) are more associated with conditions like hyperthyroidism or electrolyte imbalances rather than dehydration. Option C (Fever, rapid breathing, and increased urine output) are signs of other medical conditions such as infections or diabetes insipidus. Option D (Increased thirst and difficulty walking) can be seen in various situations but are not specific signs of dehydration in the elderly.

3. A nurse is reinforcing teaching about ways to reduce solid fat consumption with a client who has an elevated cholesterol level. Which of the following instructions should the nurse include?

A. Use oils with trans fats
B. Choose lean cuts of beef
C. Avoid purchasing beef that is a loin cut
D. Purchase chicken instead of lamb

Correct answer: B

Rationale: The correct answer is B: 'Choose lean cuts of beef.' Selecting lean cuts of beef is crucial in reducing solid fat consumption for individuals with high cholesterol levels. Lean cuts contain less saturated fat compared to fatty cuts, thus aiding in managing cholesterol levels. Option A is incorrect as oils with trans fats should be avoided since they contribute to unhealthy fats. Option C is not directly related to reducing solid fat consumption. Option D, while suggesting a leaner meat option, does not address the issue of solid fat consumption as directly as choosing lean cuts of beef.

4. A nurse is caring for a 37-year-old woman with metastatic ovarian cancer admitted for nausea and vomiting. The physician orders total parenteral nutrition (TPN), a nutritional consult, and diet recall. Which of the following is the BEST indication that the patient's nutritional status has improved after 4 days?

A. The patient eats most of the food served to her
B. The patient has gained 1 pound since admission
C. The patient's albumin level is 4.0mg/dL
D. The patient's hemoglobin is 8.5g/dL

Correct answer: C

Rationale: An improved albumin level is the best indicator of improved nutritional status after TPN. Albumin is a key protein that reflects the body's overall nutritional status and is commonly used to assess nutritional health. Choices A, B, and D are not as reliable indicators of improved nutritional status. Choice A may not accurately reflect nutritional improvement as it could be influenced by factors other than nutrition. Choice B may indicate fluid retention or loss rather than true nutritional improvement. Choice D, hemoglobin level, is more related to anemia and oxygen-carrying capacity of the blood, rather than nutritional status.

5. A nurse is caring for a client who is having difficulty voiding following the removal of an indwelling urinary catheter. Which of the following interventions should the nurse take?

A. Assess for bladder distention after 6 hours
B. Encourage the client to use a bedpan in the supine position
C. Restrict the client's intake of oral fluids
D. Pour warm water over the client's perineum

Correct answer: D

Rationale: The correct answer is to pour warm water over the client's perineum. This intervention can help stimulate voiding after catheter removal by promoting relaxation of the perineal muscles and increasing sensory input to the bladder. Assessing for bladder distention after 6 hours (Choice A) is important but not the initial intervention for difficulty voiding. Encouraging the client to use a bedpan in the supine position (Choice B) may not be effective in promoting voiding. Restricting the client's intake of oral fluids (Choice C) is not appropriate as hydration is important for urinary function.
