Correct Answer: B

Rationale: Catheter-related infections pose the greatest risk for patients in healthcare settings. Catheters are invasive devices that can introduce pathogens directly into the bloodstream, leading to severe infections. Pneumonia, intravenous line infections, and C. difficile infections are serious concerns as well, but catheter-related infections are particularly risky due to the direct access they provide for pathogens to enter the body.

Correct Answer: B

Rationale: The correct answer is B: 'Coordinating patient care with other team members.' In a multidisciplinary healthcare team, nurses collaborate with other healthcare professionals to ensure comprehensive care for patients. Working independently without consulting others (choice A) is not aligned with the collaborative nature of multidisciplinary teams. Ignoring patient concerns (choice C) goes against the core principles of patient-centered care. Making all healthcare decisions alone (choice D) contradicts the teamwork approach of a multidisciplinary team.

Correct Answer: A

Rationale: The correct answer is A: 135 to 145 milliequivalents per liter. The normal range for sodium levels in the body is expressed in milliequivalents per liter, not microequivalents. Choice B and D provide a significantly lower range which is not within the normal values for sodium. Choice C incorrectly states 'microequivalents' instead of the correct unit 'milliequivalents'. Therefore, A is the correct answer.

Correct Answer: D

Rationale: The client is likely suffering from endocarditis based on the symptoms described. Endocarditis is characterized by fever, night sweats, hematuria, splenomegaly (tenderness of the spleen), and Osler's nodes (painful nodules on the pads of the fingers or toes). While tuberculosis and AIDS/HIV can present with some similar symptoms, the presence of Osler's nodes is more specific to endocarditis. Pericarditis typically presents with chest pain, not the combination of symptoms seen in this case.

Correct Answer: C

Rationale: After a client complains of nausea and vomits one hour after taking glyburide, the priority nursing intervention should be to monitor blood glucose closely and look for signs of hypoglycemia. Vomiting could indicate that the glyburide was not properly absorbed, potentially leading to hypoglycemia. Administering glyburide again (Choice A) could worsen hypoglycemia. Administering subcutaneous insulin (Choice B) is not appropriate without assessing the blood glucose first. Monitoring for signs of hyperglycemia (Choice D) is not the immediate concern in this situation.
