1. How often should the intravenous tubing on total parenteral nutrition solutions be changed?

• A. every 24 hours
• B. every 36 hours
• C. every 48 hours
• D. every 72 hours

Correct answer: A

Rationale: The correct answer is to change the intravenous tubing on total parenteral nutrition solutions every 24 hours. This frequency is necessary due to the high risk of bacterial growth associated with TPN solutions. Changing the tubing every 24 hours helps prevent contamination and bloodstream infections. Choices B, C, and D are incorrect because waiting longer intervals increases the risk of introducing harmful bacteria into the patient's system, leading to potentially severe complications.

2. What type of immunity do vaccines provide?

• A. active
• B. passive
• C. transplacental
• D. active and passive

Correct answer: A

Rationale: Vaccines provide active immunity by stimulating the immune system to produce antibodies against specific pathogens. Choice B, passive immunity, is acquired from ready-made antibodies, not through vaccination. Choice C, transplacental immunity, is a form of passive immunity transferred from mother to infant, not acquired through vaccines. Therefore, the correct answer is active immunity.

3. When assisting the physician in performing transillumination of a client's scrotum, how should the nurse prepare for this procedure?

• A. Obtaining a flashlight and darkening the room
• B. Instructing the client to drink three glasses of water
• C. Instructing the client to take several deep breaths and bear down
• D. Telling the client that the procedure is very uncomfortable but that the discomfort will only last for a few moments

Correct answer: A

Rationale: When preparing for transillumination of the scrotum, the nurse should obtain a flashlight and darken the room. This is done to allow the strong flashlight to be shined from behind the scrotal contents. Normal scrotal contents do not appear on transillumination. Instructing the client to drink fluids or to take deep breaths and bear down is not part of the preparation for this procedure. Additionally, it is not necessary to inform the client that the procedure is uncomfortable as transillumination is a painless procedure.

4. A nurse in the newborn nursery, assisting with data collection for a newborn, prepares to measure the chest circumference. The nurse places the tape measure around the infant at which location?

• A. In the axillary area
• B. At the level of the nipples
• C. Two inches below the nipples
• D. At the level of the umbilicus

Correct answer: B

Rationale: The chest circumference of the infant is measured at the level of the nipples. It is usually 2 to 3 cm smaller than the head circumference. The average chest circumference is 30.5 to 33 cm (12-13 inches). When there is molding of the head, the head and chest measurements may be equal at birth. Placing the tape measure at the level of the nipples ensures accuracy and consistency in newborn assessment. Options A, C, and D are incorrect as the chest circumference is specifically measured at the level of the nipples to obtain precise measurements.

5. A sexually active adolescent asks the school nurse about the use of latex condoms and the reduction of the risk of sexually transmitted infections (STIs). The nurse provides which information to the adolescent?

• A. Using a latex condom is a good method for reducing the risk of sexually transmitted infections (STIs).
• B. The only way to reduce the risk of transmission of STIs is abstinence.
• C. A spermicide needs to be used along with a condom to prevent transmission of STIs.
• D. Using a latex condom can reduce the risk of transmission of STIs.

Correct answer: D

Rationale: The correct answer is that using a condom during intercourse can reduce the risk of STI transmission. Abstinence is a way to prevent STIs, but not the only way. Using a spermicide along with a condom can help prevent pregnancy, not STIs. While condoms may fail to prevent pregnancy, they are effective in reducing the risk of STI transmission. Therefore, using a latex condom for pregnancy prevention is not directly related to preventing the transmission of STIs.
