1. What is the primary purpose of dietary fiber in the diet?

A. Improving digestion
B. Providing energy
C. Aiding in the absorption of vitamins
D. Reducing cholesterol

Correct answer: D

Rationale: The primary purpose of dietary fiber in the diet is to reduce cholesterol levels. While it does aid in digestion by promoting regular bowel movements, its main role is in lowering cholesterol. Choice A is partially correct but not the primary purpose. Choice B is incorrect as fiber is not a direct source of energy. Choice C is also incorrect as the primary role of fiber is not in the absorption of vitamins.

2. What health instruction will enhance regulation of a colostomy (defecation) of clients?

A. Irrigate after lunch everyday
B. Eat fruits and vegetables in all three meals
C. Eat balanced meals at regular intervals
D. Restrict exercise to walking only

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

3. What are the responsibilities of a nurse towards a patient?

A. A registered nurse is responsible for a group of patients from their admission to their discharge
B. A registered nurse only provides care for the patient with the assistance of nursing aides
C. A nurse's only responsibility is to perform administrative duties in a healthcare setting
D. A nurse's only responsibility is to maintain hospital equipment

Correct answer: A

Rationale: A registered nurse is responsible for a group of patients from their admission to their discharge. This responsibility encompasses assessing patient needs, formulating care plans, administering medications, monitoring patient progress, and coordinating with other members of the healthcare team. Choice B is not entirely accurate because, even though nurses often work with nursing aides, the nurses themselves hold the ultimate responsibility for the overall care of the patient. Choices C and D are incorrect as they depict an incomplete and inaccurate representation of a nurse's role, which extends beyond administrative duties and equipment maintenance to primarily focus on direct patient care.

4. A client with cirrhosis and ascites is being cared for by a nurse. Which of the following interventions should the nurse include in the plan of care?

A. Decrease the client's fluid intake.
B. Increase the client's saturated fat intake.
C. Increase the client's sodium intake.
D. Decrease the client's carbohydrate intake.

Correct answer: D

Rationale: In a client with cirrhosis and ascites, decreasing carbohydrate intake is essential as it helps reduce the production of ascitic fluid. Excess carbohydrates can lead to fluid retention. Choices A, B, and C are incorrect. Decreasing fluid intake can worsen dehydration, increasing saturated fat intake is not recommended due to its impact on liver health, and increasing sodium intake can worsen fluid retention and exacerbate ascites in these clients.
