1. Select all that apply. A person who is deficient in vitamin A could consume which of the following to increase vitamin A levels?

• A. cantaloupe
• B. eggs
• C. carrots
• D. all of the above

Correct answer: D

Rationale: Vitamin A can be found in high amounts in foods like cantaloupe, eggs, carrots, and milk, all of which help to maintain healthy vision, skin, and immune function.

2. What describes a criterion used to diagnose diabetes?

• A. a plasma glucose concentration of 100 mg/dL or higher after a fast of at least 12 hours
• B. a casual blood sample of 200 mg/dL or higher in a person with classic symptoms
• C. a plasma glucose concentration measured two hours after a 200-gram glucose load is 400 mg/dL or higher
• D. a HbA1C higher than 5 percent

Correct answer: B

Rationale: A casual blood sample of 200 mg/dL or higher in a person with classic symptoms is a diagnostic criterion for diabetes. This choice aligns with the typical clinical presentation of diabetes and is a key diagnostic indicator. Choices A, C, and D do not accurately reflect the established criteria for diagnosing diabetes, making them incorrect. Choice A pertains to a fasting plasma glucose level, Choice C involves a glucose challenge test, and Choice D refers to HbA1C levels, which are used for monitoring blood sugar control over time, not for diagnosing diabetes.

3. A client was rushed in the E.R showing a whitish, leathery and painless burned area on his skin. The nurse is correct in classifying this burn as:

• A. First degree burn C. Third degree burn
• B. Second degree burn D. Partial thickness burn
• 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.

4. Chest x-ray was ordered after thoracentesis. When your client asks what is the reason for another chest x-ray, you will explain:

• A. to rule out pneumothorax
• B. to rule out any possible perforation
• C. to decongest
• D. to rule out any foreign body

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

5. If a person could not make bile, what would happen?

• A. experience fatigue, as the body would not be able to make lipid carriers to deliver fat to body cells for energy
• B. have less cholesterol being made by the liver
• C. need to consume higher levels of fat
• D. be unable to absorb most lipids, and fat would be excreted in the feces

Correct answer: D

Rationale: The correct answer is D. Bile is essential for emulsifying fats in the small intestine, allowing them to be absorbed. Without bile, most fats would not be absorbed and would be excreted in the feces. Choices A, B, and C are incorrect because the primary role of bile is in the digestion and absorption of fats, rather than affecting lipid carriers, cholesterol production, or dietary fat consumption.
