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. The client is undergoing progressive ambulation on the third day after a myocardial infarction. Which clinical manifestation would indicate that the client should not be advanced to the next level?

• A. Facial flushing
• B. A complaint of chest heaviness
• C. Heart rate increase of 10 beats/min
• D. Systolic blood pressure increase of 10 mm Hg

Correct answer: B

Rationale: The correct answer is a complaint of chest heaviness. Onset of chest pain indicates myocardial ischemia, which can be life-threatening. Chest pain in a client post-myocardial infarction should be promptly evaluated, and the activity level should not be advanced. Choices A, C, and D are not the best options because facial flushing, a heart rate increase of 10 beats/min, and a systolic blood pressure increase of 10 mm Hg are not typical indicators of myocardial ischemia or necessarily contraindications for advancing activity levels in this context.

3. The client in the Emergency Department, who has suffered an ankle sprain, should be taught to:

• A. use cold applications to the sprain during the first 24-48 hours.
• B. expect disability to decrease within the first 24 hours of injury
• C. expect pain to decrease within 3 hours after injury.
• D. begin progressive passive and active range of motion exercises immediately.

Correct answer: A

Rationale: When a client suffers an ankle sprain, the nurse should teach them to use cold applications to the sprain during the first 24-48 hours. Cold applications are believed to produce vasoconstriction and reduce the development of edema. Expecting disability to decrease within the first 24 hours of injury (choice B) is incorrect as disability and pain are anticipated to increase during the first 2-3 hours after injury. Expecting pain to decrease within 3 hours after injury (choice C) is also incorrect as pain and swelling usually increase initially. Beginning progressive passive and active range of motion exercises immediately (choice D) is not recommended; these exercises are usually started 2-5 days after the injury, according to the physician's recommendation. Treatment for a sprain involves support, rest, and alternating cold and heat applications. X-ray pictures are often necessary to rule out any fractures.

4. A 62-year-old female is being seen on a home visit by a nurse. The patient reports she has been taking Premarin for years. Which of the following would indicate an overdose?

• A. Lower extremity edema
• B. Sensory changes in the upper extremities
• C. Increased occurrence of fractures
• D. Decreased peripheral blood flow

Correct answer: A

Rationale: Lower extremity edema can indicate an overdose of Premarin. Premarin, an estrogen hormone replacement therapy, can cause fluid retention leading to edema in the lower extremities. Sensory changes in the upper extremities, increased occurrence of fractures, and decreased peripheral blood flow are not typically associated with an overdose of Premarin.

5. What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36mmHg, 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 normal ranges, indicating a state of balance in the body's acid-base levels. Choices A, C, and D are incorrect as the ABG values provided do not point towards metabolic alkalosis, respiratory acidosis, or respiratory alkalosis. Instead, the values reflect a state of equilibrium where pH, PO2, PCO2, and HCO3 levels are within the normal range.
