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. A nurse is caring for a patient in the step-down unit. The patient has signs of increased intracranial pressure. Which of the following is not a sign of increased intracranial pressure?

• A. Bradycardia
• B. Increased pupil size bilaterally
• C. Change in LOC
• D. Vomiting

Correct answer: B

Rationale: The correct answer is 'Increased pupil size bilaterally.' When assessing for signs of increased intracranial pressure, bilateral pupil dilation is not typically associated with this condition. Instead, unilateral pupil changes, especially one pupil becoming dilated or non-reactive while the other remains normal, are indicative of increased ICP. Bradycardia, a change in level of consciousness (LOC), and vomiting are commonly seen in patients with increased intracranial pressure due to the brain's response to the rising pressure. Therefore, the presence of bilateral pupil dilation goes against the typical pattern observed in patients with increased intracranial pressure.

3. A 15-year-old high school wrestler has been taking diuretics to lose weight to compete in a lower weight class. Which of the following medical tests is most likely to be given?

• A. Lab values of Potassium and Sodium
• B. Lab values of Glucose and Hemoglobin
• C. ECG
• D. CT scan

Correct answer: A

Rationale: Diuretics can disrupt the sodium and potassium balance, potentially leading to cardiac complications. Monitoring the lab values of potassium and sodium is crucial to assess electrolyte imbalances due to diuretic use. Testing glucose and hemoglobin levels is not directly related to diuretic use in this context. An ECG would be indicated if there were signs or symptoms of cardiac abnormalities, but it is not the primary test to monitor the effects of diuretics. A CT scan is not typically used to assess electrolyte imbalances caused by diuretics.

4. What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36 mmHg, and HCO3 24 mEq/L?

• A. metabolic alkalosis
• B. homeostasis
• C. respiratory acidosis
• D. respiratory alkalosis

Correct answer: B

Rationale: The correct answer is 'homeostasis.' These ABG values fall within the normal range, indicating a state of balance and homeostasis. The pH is within the normal range (7.35-7.45), the PCO2 is normal (35-45 mmHg), and the HCO3 level is also normal (22-26 mEq/L). Choice A, 'metabolic alkalosis,' is incorrect because the pH, PCO2, and HCO3 levels are not indicative of metabolic alkalosis. Choice C, 'respiratory acidosis,' is incorrect as the pH and PCO2 values are not elevated. Choice D, 'respiratory alkalosis,' is incorrect as the pH and PCO2 levels are not decreased. Therefore, the ABG values provided do not correspond to any acid-base disturbance, confirming that the patient is in a state of homeostasis.

5. At what age will vision be 20/20 in children?

• A. 4 years old
• B. 5 years old
• C. 6 years old
• D. 7 years old

Correct answer: C

Rationale: The correct answer is 6 years old. At this age, children typically have the potential for 20/20 vision. This is considered the standard age for achieving optimal vision clarity. Choices A, B, and D are incorrect as they are not typically associated with the age at which children achieve 20/20 vision.
