Correct Answer: C

Rationale: The correct answer is C: Western blot test. The Western blot test is considered the gold standard for confirming HIV diagnosis after a positive EIA result. It detects specific antibodies to HIV proteins, providing a more accurate confirmation. Other choices are incorrect because: A: Another EIA test would yield the same result as the initial EIA test. B: Viral load test measures the amount of virus in the blood and is not used to confirm HIV diagnosis. D: CD4/CD8 ratio is used to monitor immune status but not to confirm HIV diagnosis.

Correct Answer: D

Rationale: The correct answer is D: Dispose of the antineoplastic wastes in the hazardous waste receptacle. This is crucial to prevent exposure to potentially harmful substances. Here's the rationale: 1. Antineoplastic agents are hazardous chemicals that can harm individuals and the environment. 2. Proper disposal in a hazardous waste receptacle ensures safety and compliance with regulations. 3. Options A, B, and C are incorrect as adjusting doses based on symptoms, hand hygiene, and personal protective equipment are important but not as critical as proper disposal of hazardous waste in this context.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Hearing-impaired patient is likely unable to hear during an MRI due to loud noises. 2. Nurse needs to use alternative communication methods like writing or gestures. 3. Sign language interpreter may not be necessary for an MRI. 4. Lip reading may be challenging due to the noisy MRI environment. 5. Interaction should be adapted to accommodate the patient's communication needs.

Correct Answer: B

Rationale: The correct answer is B: Cholesteatoma. A red blemish behind the tympanic membrane is indicative of a cholesteatoma, which is a noncancerous cyst in the middle ear. This occurs due to the accumulation of skin cells and debris in the middle ear space. Other choices (A, C, D) are not associated with a red blemish on otoscopy. An acoustic tumor (A) typically presents as a slow-growing mass on the vestibulocochlear nerve. Facial nerve neuroma (C) involves the facial nerve and does not typically cause a red blemish. Glomus tympanicum (D) is a vascular tumor arising from the middle ear but does not usually present as a red blemish.

Correct Answer: C

Rationale: The correct answer is C: Whisper test. The nurse can perform a whisper test by whispering a series of numbers or words at a distance from the child to see if they can repeat them accurately. If the child struggles to hear and repeat the whispered words, it could indicate hearing loss. Rationale: A: Audiometry is a comprehensive hearing test that measures the range and sensitivity of hearing, not suitable for a quick preliminary assessment. B: Rinne test and D: Weber test are both tuning fork tests used to assess conductive and sensorineural hearing loss, not ideal for a quick initial screening of hearing loss. Summary: The Whisper test is the most suitable choice as it provides a quick and simple way to preliminarily assess hearing loss by evaluating the child's ability to hear and repeat whispered sounds accurately.
