Correct Answer: D

Rationale: The correct answer is D: Isolate affected residents from residents who have not developed conjunctivitis. This is the most appropriate action to prevent the spread of viral conjunctivitis in a long-term care facility. By isolating affected residents, the nurse can minimize the risk of transmission to other residents. Choice A is incorrect because prophylactic antibiotics are not effective against viral conjunctivitis. Choice B is also incorrect as normal saline does not treat viral conjunctivitis but may provide comfort. Choice C is unnecessary as viral conjunctivitis is typically diagnosed clinically and does not require culture testing.

Correct Answer: C

Rationale: The correct answer is C, Glucosuria. Preeclampsia is characterized by hypertension, proteinuria, and edema. Glucosuria is not a typical symptom of preeclampsia. Glucosuria is more commonly associated with gestational diabetes, which is a separate condition from preeclampsia. Therefore, in a pregnant patient at risk for preeclampsia, the presence of glucosuria would not be indicative of preeclampsia. The other choices, edema, proteinuria, and hypertension, are all common clinical signs seen in patients with preeclampsia.

Correct Answer: A

Rationale: The correct answer is A because providing care that fits the patient's valued life patterns and set of meanings demonstrates cultural congruence. This approach acknowledges and respects the patient's cultural background, beliefs, and preferences. It promotes patient-centered care and enhances communication and trust between the nurse and the patient. Choice B is incorrect because care based on predetermined criteria may not align with the patient's individual cultural needs. Choice C is incorrect as it does not prioritize the patient's values and preferences. Choice D is incorrect because providing care based solely on the values of the professional health care system may not consider the cultural diversity of the patient population.

Choice C is unnecessary as viral conjunctivitis is typically diagnosed clinically and does not require culture testing.

Correct Answer: D

Rationale: Rationale: Option D is correct because raising the head of the bed promotes a more natural position for defecation, allowing gravity to assist. This position helps align the rectum and anal canal, making it easier for the patient to have a bowel movement. Administering laxatives (Option C) may help, but adjusting the bed position is a non-invasive and more immediate intervention. Withholding pain medication (Option B) could lead to unnecessary discomfort for the patient. Administering a barium enema (Option A) is not indicated for addressing difficulty with defecation.
