1. Which of the following lab values would indicate symptomatic AIDS in the medical chart? (T4 cell count per deciliter)

• A. Greater than 1000 cells per deciliter
• B. Less than 500 cells per deciliter
• C. Greater than 2000 cells per deciliter
• D. Less than 200 cells per deciliter

Correct answer: D

Rationale: A T4 cell count of less than 200 cells per deciliter indicates symptomatic AIDS. This severe depletion of T4 cells signifies advanced HIV infection and a significantly compromised immune system. Choices A, B, and C are incorrect because T4 cell counts above 2000, above 1000, or below 500 cells per deciliter, respectively, are not indicative of symptomatic AIDS.

2. Which of the following is the drug of choice to decrease uric acid levels?

• A. prednisone (Colisone)
• B. allopurinol (Zyloprim)
• C. indomethacin (Indocin)
• D. hydrochlorothiazide (HydroDiuril)

Correct answer: B

Rationale: Allopurinol is the correct drug to decrease uric acid levels as it is used to treat gout by reducing uric acid formation. Prednisone is a corticosteroid that decreases inflammation, not uric acid levels. Indomethacin is an analgesic, anti-inflammatory, and antipyretic agent, not specifically used to reduce uric acid levels. Hydrochlorothiazide is a thiazide diuretic primarily used for treating hypertension and edema, not for reducing uric acid levels.

3. Which infection control measure is the priority for the nurse to implement in the care provided for a child admitted to the hospital with bacterial meningitis?

• A. Place the child in a private room
• B. Gowns and masks must be worn by all personnel in the child's room
• C. Visitors are restricted to parents only
• D. Hand washing is required by all personnel and visitors having contact with the child

Correct answer: B

Rationale: The priority control measure for the nurse to implement in caring for a child with bacterial meningitis is ensuring that gowns and masks are worn by all personnel in the child's room. This measure is crucial as the child with bacterial meningitis is contagious for at least 24 hours after starting antibiotics, necessitating airborne precautions to prevent the spread of infection to healthcare workers and other patients. Placing the child in a private room (Choice A) is important but secondary to preventing infection transmission. Restricting visitors to parents only (Choice C) is also significant but not as critical as ensuring proper infection control measures. While hand washing (Choice D) is essential, the immediate need to prevent airborne transmission in the child's room takes precedence.

4. A client begins a regimen of chemotherapy. Her platelet count falls to 98,000. Which action is least likely to increase the risk of hemorrhage?

• A. Test all excreta for occult blood.
• B. Use a soft toothbrush or foam cleaner for oral hygiene.
• C. Implement reverse isolation.
• D. Avoid IM injections.

Correct answer: C

Rationale: The correct answer is to implement reverse isolation. Reverse isolation is a protective measure used to protect patients from infections, not to affect the risk of hemorrhage. Testing all excreta for occult blood (Choice A) is important to monitor for signs of internal bleeding. Using a soft toothbrush or foam cleaner for oral hygiene (Choice B) is recommended to prevent gum bleeding. Avoiding IM injections (Choice D) is crucial to reduce the risk of bleeding in a client with a low platelet count. Therefore, among the given options, implementing reverse isolation is the least likely to increase the risk of hemorrhage.

5. How can light therapy be effective?

• A. overcoming weight problems.
• B. helping with allergies.
• C. use in alternative medical treatments.
• D. working with sleep patterns.

Correct answer: D

Rationale: Light therapy can be effective in treating problems associated with sleep patterns, stress, moods, jaundice in newborns, and seasonal affective disorders. While light therapy is not typically used for overcoming weight problems or helping with allergies, it is specifically known for its benefits in regulating sleep patterns. Therefore, the correct answer is 'working with sleep patterns.' Choices A, B, and C are incorrect as light therapy is not commonly utilized for overcoming weight problems, helping with allergies, or as a general alternative medical treatment.
