Nursing Elites

1. Which vitamin acts most like a hormone?

• A. Vitamin A
• B. Vitamin B
• C. Vitamin D
• D. Vitamin C

Correct answer: C

Rationale: The correct answer is Vitamin D. Although vitamin D, also known as calciferol, has been called a vitamin, it is more appropriately classified as a hormone. Like hormones, vitamin D acts to control the function of other cell types. For example, it helps the body absorb and regulate skeletal calcium and phosphorus levels. Choice A (Vitamin A) plays a crucial role in vision and immune function. Choice B (Vitamin B) is a complex of different vitamins that play various roles in the body. Choice D (Vitamin C) is important for collagen production and acts as an antioxidant.

2. In responding to the care concerns of children with severe disease, referral to the hospital is of the essence especially if the child manifests which of the following?

• A. Wheezing
• B. Stop feeding well
• C. Fast breathing
• D. Difficulty to awaken

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. Which vitamin is essential for proper blood clotting?

• A. Vitamin A
• B. Vitamin E
• C. Vitamin K
• D. Vitamin C

Correct answer: C

Rationale: Vitamin K is vital for the synthesis of clotting factors, which are necessary for proper blood clotting. Vitamin A (Choice A) is important for vision and skin health, not blood clotting. Vitamin E (Choice B) is an antioxidant that helps protect cells from damage but is not directly involved in blood clotting. Vitamin C (Choice D) is essential for collagen synthesis and a healthy immune system, but it does not play a direct role in blood clotting.

4. A client is receiving education from a nurse regarding the dietary changes needed for weight loss. Which of the following actions should the nurse perform first?

• A. Educate the client about daily caloric requirements.
• B. Determine the client’s daily caloric intake.
• C. Provide the client with meal planning information.
• D. Show the client how to identify the fat content of packaged foods.

Correct answer: B

Rationale: The correct answer is to determine the client’s daily caloric intake first. This step is crucial in understanding the client's current dietary habits and establishing a baseline for creating an effective weight loss plan. Educating the client about daily caloric requirements (Choice A) can only be done effectively after knowing the client's current intake. Providing meal planning information (Choice C) and teaching the client how to identify fat content in foods (Choice D) come after determining the baseline caloric intake to tailor the plan accordingly.

5. What stimulates bile secretion from the liver to the small intestine?

• A. Pepsin
• B. Salivary Amylase
• C. CCK
• D. Secretin

Correct answer: C

Rationale: Cholecystokinin (CCK) is the hormone that stimulates the release of bile from the gallbladder into the small intestine, aiding in fat digestion. Pepsin is an enzyme in the stomach that breaks down proteins into smaller peptides, not involved in bile secretion. Salivary Amylase is an enzyme in saliva that initiates starch digestion in the mouth, not related to bile secretion. Secretin is a hormone that regulates the release of gastric juice in the stomach and triggers the pancreas to neutralize stomach acid in the small intestine, but it does not stimulate bile secretion.
