1. An estimated _____ percent of persons in the United States who have HIV infection are unaware that they are infected.

• A. 4%
• B. 21%
• C. 34%
• D. 49%

Correct answer: B

Rationale: The correct answer is B: '21%'. Approximately 21% of persons in the United States who have HIV infection are unaware that they are infected. This percentage represents a significant portion of individuals who are not aware of their HIV status, highlighting the importance of increased testing and awareness campaigns. Choices A, C, and D are incorrect as they do not align with the estimated percentage provided in the context.

2. Each of the following describes the physiologic roles of water, except one. Which is the exception?

• A. Acts as a solvent for chemical reactions.
• B. Maintains stability of body fluids.
• C. Enables transport of nutrients and excretion of waste.
• D. Regulates temperature by pooling as perspiration on skin.

Correct answer: D

Rationale: The correct answer is D. Water regulates body temperature by evaporating as perspiration from the skin, not by pooling. When sweat evaporates from the skin, it takes away heat, which helps cool the body. Choices A, B, and C are correct because water acts as a solvent for chemical reactions, maintains the stability of body fluids, and enables the transport of nutrients and excretion of waste, respectively.

3. A client who was normal weight before pregnancy asks about the recommended weight gain during pregnancy. What should the nurse advise?

• A. 18-40 pounds
• B. 25-35 pounds
• C. 11-20 pounds
• D. 15-25 pounds

Correct answer: B

Rationale: The correct answer is B: 25-35 pounds. According to standard prenatal guidelines, a client with a normal pre-pregnancy weight is recommended to gain between 25-35 pounds during pregnancy. This weight gain is important for the overall health of the mother and the developing baby. Choices A, C, and D are incorrect because they do not fall within the recommended weight gain range for a client with a normal pre-pregnancy weight.

4. A nurse is providing teaching to a group of parents of newborns who are planning to formula feed. Which of the following statements by a parent indicates a need for further teaching?

• A. "I will give formula to my baby at room temperature."
• B. "I will ensure my baby's feeds last 10 to 15 minutes."
• C. "I will burp my baby halfway through each feeding."
• D. "I will watch for signs my baby is full and stop the feeding."

Correct answer: B

Rationale: The correct answer is, "I will ensure my baby's feeds last 10 to 15 minutes." This statement indicates a need for further teaching because it suggests a strict time limit for feedings, which may not be appropriate for a newborn. Newborns should be allowed to feed as long as they want, typically around 20-30 minutes per breast if breastfeeding, or on-demand with formula. Choices A, C, and D demonstrate proper feeding practices such as feeding at room temperature, burping halfway through each feeding, and watching for signs of fullness to stop the feeding, which are all appropriate responses by a parent of a formula-fed newborn.

5. Which statement about essential nutrients should the nurse include?

• A. Fat-containing foods can help to decrease triglyceride levels.
• B. Animal sources of protein contain 20 essential amino acids.
• C. Carbohydrates are the primary source of fuel for muscles and the brain.
• D. High-fiber foods are a good source of energy.

Correct answer: C

Rationale: The correct answer is C because carbohydrates are indeed the primary source of fuel for muscles and the brain. Choice A is incorrect because while certain fats are essential, they do not help decrease triglyceride levels. Choice B is incorrect because animal sources of protein do not contain all 20 essential amino acids. Choice D is incorrect because although high-fiber foods are important for digestion and overall health, they are not a direct source of energy.
