1. The healthcare provider sustains a needle puncture that requires HIV prophylaxis. Which of the following medication regimens should be used?

• A. an antibiotic such as Metronidazole and a protease inhibitor (Saquinavir)
• B. two non-nucleoside reverse transcriptase inhibitors
• C. one protease inhibitor such as Nelfinavir
• D. two protease inhibitors

Correct answer: B

Rationale: In the scenario of a needle puncture requiring HIV prophylaxis, the CDC recommends initiating treatment with two non-nucleoside reverse transcriptase inhibitors, unless there is drug resistance. This regimen is preferred over other options such as a single protease inhibitor or two protease inhibitors due to its effectiveness and safety profile in this specific context. Non-nucleoside reverse transcriptase inhibitors are commonly used in post-exposure prophylaxis due to their activity against HIV and lower risk of resistance development compared to other antiretroviral drug classes.

2. Ms. Petty is having difficulty falling asleep. Which of the following measures promote sleep?

• A. exercising vigorously for 20 minutes each night starting at 9:30 p.m.
• B. taking a cool shower and drinking a hot cup of tea
• C. watching TV nightly until midnight
• D. getting a back rub and drinking a glass of warm milk

Correct answer: D

Rationale: Getting a back rub and drinking a glass of warm milk are appropriate measures to promote sleep as they can help relax the body and induce sleepiness. Exercising vigorously, as suggested in choice A, can be counterproductive as it stimulates the body rather than relaxing it, making it harder to fall asleep. Choice B, taking a cool shower and drinking a hot cup of tea, may also increase alertness due to the temperature changes and the caffeine in tea, which can interfere with falling asleep. Watching TV until midnight, as in choice C, exposes the individual to blue light and mental stimulation, making it harder to fall asleep. Therefore, choice D is the best option to promote sleep in this scenario.

3. Several passengers aboard an airliner suddenly become weak and suffer breathing difficulty. The diagnosis is likely to be:

• A. Outbreak of Asian flu.
• B. Chemical exposure.
• C. Bacterial pneumonia.
• D. Allergic reaction.

Correct answer: B

Rationale: The most likely cause of groups of individuals suddenly experiencing similar signs of illness all at once is a chemical exposure. In this scenario, considering the sudden onset of symptoms in multiple passengers on an airliner, the symptoms are more indicative of a chemical exposure rather than Asian flu, bacterial pneumonia, or an allergic reaction. Asian flu, bacterial pneumonia, and allergic reactions do not typically manifest in a way that would affect a group of individuals simultaneously. Therefore, the correct diagnosis in this case is likely to be a chemical exposure.

4. A new mother asks the nurse, 'I was told that my infant received my antibodies during pregnancy. Does that mean that my infant is protected against infections?' Which statement should the nurse make in response to the mother?

• A. The immune system of an infant is immature, and the infant is at risk for infection.
• B. The transfer of your antibodies protects your infant until the infant is 12 months old.
• C. Yes, your infant is protected from all infections.
• D. If you breastfeed, your infant is protected from infection.

Correct answer: A

Rationale: The transplacental transfer of maternal antibodies supplements the infant's weak response to infection until approximately 3 to 4 months of age. While the infant starts producing immunoglobulin (Ig) soon after birth, it only reaches about 60% of the adult IgG level, 75% of the adult IgM level, and 20% of the adult IgA level by 1 year of age. Breast milk provides additional IgA protection. Although the immune system matures during infancy, full protection against infections is not achieved until early childhood, putting the infant at risk for infections. Choice B is incorrect because maternal antibody protection typically lasts around 3 to 4 months, not until the infant is 12 months old. Choice C is incorrect as infants are not shielded from all infections due to their immature immune system. Choice D is incorrect because while breastfeeding offers extra protection, it does not guarantee complete immunity against infections.

5. In which of the following conditions might increased cortisol levels be found?

• A. Cushing's syndrome
• B. Addison's disease
• C. Renal failure
• D. Congestive heart failure

Correct answer: A

Rationale: Cushing's syndrome is characterized by increased cortisol levels due to the overproduction of cortisol by the adrenal glands. This excess cortisol can lead to various symptoms and complications. Addison's disease is associated with decreased cortisol levels as it results from adrenal insufficiency, making it an incorrect choice in this context. Renal failure and congestive heart failure are not typically linked to abnormal cortisol levels, further indicating that they are not the conditions where increased cortisol levels are found.
