Correct Answer: D

Rationale: The correct answer is D: Lithotomy position. In lithotomy position, the patient's legs are elevated and positioned higher than the heart, which can lead to venous stasis and increase the risk of deep vein thrombosis (DVT). This position compresses the femoral veins, hindering blood flow and predisposing the patient to DVT formation. Summary: A: Fowlers position - Not typically associated with increased DVT risk. B: Prone position - Not typically associated with increased DVT risk. C: Supine position - Generally considered a safe position regarding DVT risk.

Correct Answer: A

Rationale: Step 1: Serous otitis media is common in children due to eustachian tube dysfunction, not usually related to systemic infections. Step 2: Recurrent infections may indicate age-related changes like decreased eustachian tube function. Step 3: Age-related physiologic changes can lead to poor drainage, causing recurrent otitis media. Step 4: Therefore, choice A is correct as it aligns with the typical presentation of serous otitis media in the context of age. Summary: Choice B is incorrect as there is no indication for temporary mobility restriction. Choice C is incorrect as serous otitis media does not typically warrant assessment for nasopharyngeal cancer. Choice D is incorrect as blood cultures are not typically indicated for serous otitis media.

Correct Answer: C

Rationale: The correct answer is C: Narrative. The nurse is using a narrative interaction by asking the patient to share a personal story. This helps the patient express their experiences, emotions, and perspectives, promoting a deeper understanding of their care needs. A: Nonjudgmental is incorrect as it focuses on avoiding biases. B: Socializing is incorrect as it implies casual conversation. D: SBAR is incorrect as it stands for Situation, Background, Assessment, and Recommendation, used for concise communication in healthcare settings.

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: bacterial endocarditis. Mitral valve stenosis increases the risk of bacterial endocarditis due to turbulent blood flow and potential damage to the heart valve. Prophylactic antibiotics are recommended before certain procedures to prevent bacterial endocarditis in patients with underlying cardiac conditions. Choice A, hypertension, is incorrect as mitral valve stenosis does not directly increase the risk of developing hypertension. Choice B, postpartum infection, is not directly related to the risk associated with mitral valve stenosis. Choice D, upper respiratory infections, is not a specific risk associated with mitral valve stenosis in pregnant patients.
