Nursing Elites

1. Which enzyme digests fiber in the large intestine?

• A. salivary amylase
• B. pancreatic amylase
• C. cellulase
• D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.

2. A client who is breastfeeding is being taught diet modification by a nurse. Which of the following statements by the client indicates an understanding of the teaching?

• A. I should drink an 8-ounce glass of water each time my baby nurses.
• B. I should take a 1500-milligram iron supplement daily.
• C. I can eat a 2500-calorie daily diet to lose 1 lb per week.
• D. I can eat ounces of swordfish daily.

Correct answer: A

Rationale: The correct answer is A because drinking an 8-ounce glass of water each time the baby nurses helps maintain hydration and support milk production. Choice B is incorrect as the need for iron supplementation should be discussed with a healthcare provider. Choice C is incorrect as a 2500-calorie diet is not typically recommended for weight loss during breastfeeding. Choice D is incorrect as consuming high levels of swordfish is not advisable due to its mercury content, which can be harmful to the baby.

3. Why is atherosclerosis dangerous to arterial function?

• A. It diminishes central circulation
• B. It causes decreased blood pressure on artery walls
• C. It narrows the arterial lumen so a clot can easily block it
• D. It increases arterial elasticity

Correct answer: C

Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.

4. For a patient with celiac disease, which dietary modification is necessary?

• A. Increase protein intake
• B. Avoid gluten
• C. Increase dairy intake
• D. Avoid lactose

Correct answer: B

Rationale: The correct answer is B: Avoid gluten. Patients with celiac disease have an immune reaction to gluten, a protein found in wheat, barley, and rye. Therefore, it is crucial for individuals with celiac disease to avoid gluten-containing products. Increasing protein intake (Choice A) is not specifically necessary for celiac disease management. Increasing dairy intake (Choice C) is unrelated to the dietary requirements of individuals with celiac disease. Avoiding lactose (Choice D) is relevant for individuals with lactose intolerance, not celiac disease. Therefore, the only necessary modification for a patient with celiac disease is to avoid gluten.

5. When surgery is on-going, who coordinates the activities outside, including the family?

• A. Orderly/clerk C. Circulating Nurse
• B. Nurse Supervisor D. Anesthesiologist
• C.
• D.

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
