1. For patients with anemia, which vitamin is crucial for the absorption of iron?

A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin E

Correct answer: B

Rationale: The correct answer is Vitamin C. Vitamin C enhances the absorption of non-heme iron, which is crucial for patients with anemia. Vitamin A (Choice A) is not directly involved in iron absorption. Vitamin D (Choice C) helps with calcium absorption, not iron. Vitamin E (Choice D) does not have a significant role in iron absorption.

2. A healthcare professional is reviewing the laboratory findings of a client who has heart failure. Which of the following findings indicates that the client is experiencing fluid volume excess?

A. BUN 8 mg/dL
B. Hgb 15 g/dL
C. Creatinine 0.8 mg/dL
D. Sodium 140 mEq/L

Correct answer: A

Rationale: A BUN level of 8 mg/dL indicates fluid volume excess in a client with heart failure. BUN (Blood Urea Nitrogen) levels can be low in fluid overload due to hemodilution, a common occurrence in heart failure. High levels of BUN usually indicate dehydration or impaired renal function, which are not the case in fluid volume excess. Choices B, C, and D are within normal ranges and do not specifically indicate fluid volume excess.

3. For a patient on a ketogenic diet, which macronutrient is primarily increased?

A. Carbohydrates
B. Protein
C. Fats
D. Fiber

Correct answer: C

Rationale: The correct answer is C: Fats. A ketogenic diet is characterized by high fat intake, moderate protein intake, and very low carbohydrate intake. This diet aims to shift the body's metabolism to use fat as the primary source of energy instead of carbohydrates. Increasing fat intake while reducing carbohydrates is essential for achieving and maintaining a state of ketosis. Therefore, choices A, B, and D are incorrect as they do not align with the macronutrient adjustments required for a ketogenic diet.

4. What type of diet would most likely benefit a patient with cystic fibrosis?

A. Low sodium
B. Low fat
C. Clear liquid
D. High calorie, high protein

Correct answer: D

Rationale: Patients with cystic fibrosis often have malabsorption issues, leading to increased energy needs. A high-calorie, high-protein diet is recommended to help meet these needs, support growth, and maintain overall health. Choices A, B, and C do not address the specific dietary requirements associated with cystic fibrosis, making them less beneficial for these patients.

5. The psychosocial task of a 55 year old adult client is:

A. Industry vs. Inferiority
B. Intimacy vs. Isolation
C. Integrity vs. Despair
D. Generativity vs. Stagnation

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.
