Nursing Elites

1. What best describes a task of the registered dietitian?

• A. administering total parenteral nutrition
• B. administering formula through feeding tubes
• C. prescribing diet orders
• D. conducting nutrition assessments

Correct answer: D

Rationale: The correct answer is D, conducting nutrition assessments. Registered dietitians are responsible for assessing an individual's nutritional status, dietary intake, and health needs. This assessment forms the basis for developing personalized nutrition care plans. Choices A and B involve the administration of specialized nutrition support, which is typically done by healthcare providers with specific training in those areas. Choice C, prescribing diet orders, may fall outside the scope of practice for a dietitian as they focus more on assessment, education, and counseling related to nutrition rather than prescribing medical treatments.

2. Stimulates secretion of bicarbonate ions and digestive enzymes from the pancreas to the small intestine:

• A. pepsin
• B. salivary amylase
• C. CCK
• D. secretin

Correct answer: D

Rationale: Secretin stimulates the pancreas to release bicarbonate ions to neutralize stomach acid and digestive enzymes into the small intestine.

3. What special consideration should be taken into account when Mario prepares Richard for postural drainage and percussion?

• A. Monitoring a respiratory rate of 16 to 20 per minute
• B. Assessing the client's ability to tolerate sitting and lying positions
• C. Ensuring the client is free of signs of infection
• D. Knowing the time of the client's last food and fluid intake

Correct answer: A

Rationale: The correct answer is A, 'Monitoring a respiratory rate of 16 to 20 per minute'. When performing postural drainage and percussion, it is crucial to monitor the respiratory rate to ensure the safety and effectiveness of the procedure. Choice B, 'Assessing the client's ability to tolerate sitting and lying positions', while important, is not directly related to the specifics of postural drainage and percussion. Similarly, option C, 'Ensuring the client is free of signs of infection', although important, is not directly linked to the procedure. Option D, 'Knowing the time of the client's last food and fluid intake', might be relevant for other procedures, but it is not the primary consideration for postural drainage and percussion.

4. Each nonnutritive sweetener can be recommended to patients with phenylketonuria, except one. Which one is the exception?

• A. Cyclamate
• B. Acesulfame-K
• C. Saccharin
• D. Aspartame

Correct answer: D

Rationale: The correct answer is D, Aspartame. Aspartame contains phenylalanine, which is contraindicated for individuals with phenylketonuria (PKU), a genetic disorder that impairs phenylalanine metabolism. Therefore, patients with PKU should avoid aspartame. Choices A, B, and C (Cyclamate, Acesulfame-K, Saccharin) are considered safe for individuals with PKU as they do not contain phenylalanine and can be recommended as alternatives to sugar for these patients.

5. A nurse is providing teaching to a group of adult athletes about preventing the effects of dehydration on the body. Which of the following manifestations should the nurse include in the teaching?

• A. Impaired motor control
• B. Drop in body temperature during exercise
• C. Increase in appetite
• D. Decreased resting heart rate

Correct answer: A

Rationale: Dehydration can lead to impaired motor control due to electrolyte imbalances affecting muscle function. Choices B, C, and D are incorrect. Dehydration typically causes an increase in body temperature during exercise, not a drop. Dehydration is more likely to suppress appetite, leading to a decrease rather than an increase in appetite. Also, dehydration often results in an increased heart rate rather than a decreased resting heart rate.
