1. What is the most likely demonstration of cardiac cachexia?

• A. Decreased physical activity
• B. Weight loss and tissue wasting
• C. Poor urine output and tissue edema
• D. Cardiac arrhythmia and wet lung sounds

Correct answer: B

Rationale: Cardiac cachexia is a condition characterized by severe weight loss and tissue wasting. This typically occurs in patients suffering from heart failure due to an increased energy expenditure and reduced appetite, which is why choice B is the correct answer. The other choices are incorrect as they do not accurately describe the symptoms of cardiac cachexia. Decreased physical activity (choice A) can be a result of many conditions, not specifically cardiac cachexia. Poor urine output and tissue edema (choice C) are more indicative of kidney problems rather than cardiac cachexia. Finally, cardiac arrhythmia and wet lung sounds (choice D) are symptoms related to other cardiac conditions, not specifically to cardiac cachexia.

2. A client receiving total parenteral nutrition (TPN is awaiting the next container. What fluid should the nurse infuse in the interim?

• A. Dextrose 5% in water
• B. 0.9% sodium chloride
• C. Dextrose 10% in water
• D. Lactated Ringer's solution

Correct answer: B

Rationale: The correct answer is 0.9% sodium chloride. When a client receiving TPN is awaiting the next container, infusing 0.9% sodium chloride is the appropriate choice to maintain fluid and electrolyte balance. Dextrose solutions are not recommended as they do not provide sufficient nutrition. Lactated Ringer's solution contains electrolytes but lacks essential nutrients found in TPN, making it an inadequate choice during the delay in TPN delivery.

3. A patient is being discharged with a vitamin K deficiency. What food should the nurse recommend to the patient to include in their diet?

• A. Oranges
• B. Spinach
• C. Fish
• D. Nuts

Correct answer: B

Rationale: Spinach is an excellent source of vitamin K, which plays a vital role in blood clotting and bone health. Oranges, fish, and nuts do not contain significant amounts of vitamin K, making them less suitable choices to address a vitamin K deficiency. Therefore, the correct recommendation for a patient with a vitamin K deficiency would be to include spinach in their diet to help replenish this essential vitamin.

4. According to the dietary reference intakes, what percentage of your daily calorie intake should ideally come from carbohydrates?

• A. 10-35%
• B. 20-35%
• C. 40-50%
• D. 45-65%

Correct answer: D

Rationale: Carbohydrates should ideally make up 45-65% of your total daily caloric intake, according to the Dietary Reference Intakes (DRIs). This range provides the necessary energy for bodily functions and activities. Choices A, B, and C are incorrect because they fall outside the recommended range for carbohydrate intake based on the DRIs.

5. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?

• A. The body can produce sufficient amounts of vitamin D from sunlight.
• B. UV radiation can convert a precursor of vitamin D to vitamin D3 by penetrating uncovered skin.
• C. Sunscreen blocks the formation of vitamin D3.
• D. By the age of 70 years, the skin generally produces vitamin D at only half the level it did at the age of 20 years.

Correct answer: C

Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.
