Correct Answer: A

Rationale: The correct answer is A because instilling the medication in the conjunctival sac allows for direct absorption into the eye tissues. This method ensures that the medication reaches the target area for treating glaucoma effectively. Maintaining a supine position (choice B) or keeping the eyes closed (choice C) after administration does not enhance absorption and may lead to wasted medication. Applying the medication to the sclera (choice D) is incorrect as it does not target the specific area needed for treating glaucoma.

Correct Answer: A

Rationale: Rationale: The correct answer is A because rods are responsible for vision in low light conditions. By ensuring adequate lighting in the patient's room, the nurse can optimize the patient's visual acuity. This will help the patient navigate their environment more safely. Summary: - B is incorrect because dim lighting would further limit the patient's already compromised vision. - C is incorrect as the patient's ability to perceive color may not be affected by rod dysfunction. - D is incorrect as the patient may struggle to see fine details due to rod impairment.

Correct Answer: B

Rationale: The correct answer is B because brachytherapy does not pose a risk to the patient's daughter or her unborn child. Brachytherapy involves placing radioactive sources inside or near the tumor, which does not make the patient radioactive. The radiation does not travel far and does not pose a risk to others. Therefore, the daughter and her infant are safe from any radiation exposure. Choices A, C, and D are incorrect because there is no need for the patient to avoid contact with the baby after delivery, the brachytherapy is not contraindicated for safety reasons, and there is no requirement for the patient to avoid close contact with his daughter for 2 months.

Correct Answer: D

Rationale: The correct answer is D: Obtain a stool culture to identify possible pathogens. This is the most appropriate nursing intervention because chronic diarrhea in a patient with AIDS can be caused by various pathogens such as parasites, bacteria, or viruses. By obtaining a stool culture, the healthcare team can identify the specific pathogen responsible for the diarrhea and initiate targeted treatment. A: Positioning the patient in the high Fowler's position is not directly related to addressing the underlying cause of chronic diarrhea in this patient. B: Temporarily eliminating animal protein from the patient's diet may not be necessary or effective in treating chronic diarrhea without knowing the specific cause identified through stool culture. C: Making sure the patient eats raw fruit is not recommended as raw fruits can sometimes worsen diarrhea due to their high fiber content and potential for carrying pathogens. In summary, obtaining a stool culture is the most appropriate intervention as it helps identify the specific pathogen causing the diarrhea, while the other options do not directly address the underlying cause.

Correct Answer: B

Rationale: The correct answer is B: Sandostatin. This drug is a somatostatin analog that can help manage HIV-related chronic severe diarrhea by reducing gastrointestinal secretions. Sandostatin works by inhibiting the release of various hormones and neurotransmitters in the gut, which can help control diarrhea in HIV patients. Rationale: A: Zithromax is an antibiotic that is not typically used to manage chronic severe diarrhea in HIV patients. C: Levaquin is also an antibiotic and not indicated for managing diarrhea in HIV patients. D: Biaxin is another antibiotic and not the appropriate choice for managing chronic severe diarrhea in HIV patients. In summary, Sandostatin is the correct choice as it specifically targets the underlying cause of diarrhea in HIV patients by reducing gastrointestinal secretions, whereas the other options are antibiotics that are not indicated for this purpose.
