A nurse is assessing a client who reports a possible exposure to HIV. Which of the following findings should the nurse identify as an early manifestation of HIV infection?

Correct Answer: B

Rationale: The correct answer is B: Fatigue. A client with early HIV infection can be asymptomatic or experience symptoms like viral infections, such as fever, rash, and fatigue. Fatigue is a common early manifestation of HIV infection due to the body's immune response. Stomatitis (choice A) is more commonly associated with oral health issues or infections. Wasting syndrome (choice C) and lipodystrophy (choice D) are more advanced manifestations seen in later stages of HIV infection, characterized by severe weight loss and changes in body fat distribution, respectively.

Correct Answer: C

Rationale: The correct information that the nurse should include in the teaching about a CPAP device is that it delivers a preset amount of airway pressure throughout the breathing cycle. This consistent positive airway pressure helps keep the airway open during both inspiration and expiration. Choice A is incorrect as CPAP does not deliver pressure only at the beginning of each breath. Choice B is incorrect because CPAP provides a constant level of pressure without continuous adjustments throughout the cycle. Choice D is incorrect as CPAP does not provide positive pressure at the end of each breath; instead, it maintains a continuous positive pressure.

Correct Answer: D

Rationale: The priority action is to verify the prescription with the provider. Verifying the prescription ensures patient safety by preventing fluid volume overload and dysrhythmias, which can result from infusing potassium too rapidly. Teaching the client about IV extravasation, evaluating IV patency, and consulting with the pharmacist are important but should come after verifying the prescription to ensure the ordered treatment is appropriate and safe for the client's condition.

Correct Answer: D

Rationale: The correct answer is D. During an electromyography (EMG) procedure, small needle electrodes are inserted into the muscles to identify muscle weakness and evaluate local nerve responses. This information is crucial for the client to know beforehand. Choice A is incorrect because radioisotopes are not used in EMG procedures. Choice B is incorrect because flushing is not a common occurrence during EMG. Choice C is incorrect because claustrophobia is more relevant to MRI or CT scans, not EMG procedures.

Correct Answer: D

Rationale: The correct answer is D. The nurse should instruct the client to avoid corticosteroids and vitamin C prior to testing to prevent false-positive results. Choice A is incorrect because stool samples from bowel movements, not from digital rectal examinations, are used for FOBT. Choice B is incorrect because a stimulant laxative is not typically prescribed before FOBT; rather, the client is instructed to follow specific dietary restrictions. Choice C is incorrect because biennial fecal occult blood testing for colorectal cancer screening usually begins at 50 years old, not 40.
