Nursing Elites

1. The purpose of chest percussion and vibration is to loosen secretions in the lungs. The difference between the procedures is:

• A. Percussion uses only one hand, while vibration uses both hands
• B. Percussion delivers cushioned blows to the chest with cupped palms, while vibration gently shakes secretions loose
• C. In both percussion and vibration, the hands are not on top of each other, and hand action is not in tune with the client's breath
• D. Percussion slaps the chest to loosen secretions, while vibration shakes the secretions along with the inhalation

Correct answer: D

Rationale: Chest percussion involves the use of rhythmic tapping to dislodge mucus from the lungs, facilitating its movement toward the larger airways where it can be expelled. This technique is particularly important in conditions where mucus retention is a significant risk factor for infection. The key difference between chest percussion and vibration is that percussion involves slapping the chest to loosen secretions, while vibration involves shaking the secretions along with the inhalation, aiding in moving the loosened secretions upwards for easier removal. Choices A, B, and C do not accurately describe the main difference between chest percussion and vibration, making them incorrect.

2. Each statement is true of water-soluble vitamins, except one. Which is it?

• A. Act as coenzymes
• B. Deficiencies develop rapidly
• C. Daily intake is necessary
• D. Absorbed in the jejunum

Correct answer: B

Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.

3. Which of the following treatments is not recommended for a child classified with no dehydration?

• A. Administering 1,000 ml to 1,400 ml within 4 hours
• B. Continuing feeding
• C. Allowing the child to take as much fluid as he wants
• D. Returning the child to the doctor if the condition worsens

Correct answer: B

Rationale: The correct answer is B. Continuing feeding is a recommended treatment for a child classified with no dehydration. This helps maintain the child's nutritional status and supports recovery. Options A, C, and D are appropriate interventions for a child with no dehydration. Option A ensures adequate fluid intake, option C promotes hydration, and option D ensures appropriate follow-up if the condition worsens.

4. Protein-energy malnutrition (PEM) may be responsible for the increased incidence of noma and necrotizing ulcerative gingivitis (NUG) because these conditions are associated with depressed immune responses caused by nutritional deficiencies.

• A. Both the statement and the reason are correct and related
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: The corrected question highlights that protein-energy malnutrition weakens the immune system, making individuals more susceptible to conditions like noma and NUG, which are linked to compromised immunity. Choice A is correct because the statement and reason are both accurate and directly related. Protein-energy malnutrition does result in depressed immune responses, which can predispose individuals to noma and NUG. Choice B is incorrect because the statement and reason are indeed related. Choice C is incorrect as both the statement and reason are accurate. Choice D is also incorrect as the statement is correct and directly supports the reason provided.

5. A nurse is teaching a group of clients about stress. Which of the following should the nurse include in the teaching?

• A. Protein requirements decrease in times of stress.
• B. Acute stress causes an increase in metabolism.
• C. Stress causes a positive nitrogen balance in the body.
• D. Glucose is broken down more slowly during times of stress.

Correct answer: B

Rationale: The correct answer is B: Acute stress causes an increase in metabolism. During acute stress, the body's fight-or-flight response is activated, leading to an increase in metabolism to provide energy for the body to respond to the stressor. Choices A, C, and D are incorrect. Protein requirements actually increase during times of stress to support the body's needs. Stress typically leads to a negative nitrogen balance in the body, not a positive one. Glucose is broken down more rapidly, not slowly, during times of stress to provide immediate energy.
