Correct Answer: B

Rationale: Patient advocacy in nursing entails ensuring that patients' rights and preferences are respected. This involves advocating for the patients' best interests, supporting informed decision-making, and safeguarding their autonomy. Choice A is incorrect because patient advocacy focuses on the patient's needs, not the healthcare team's. Choice C is incorrect as patient advocacy aims to empower patients and enhance their autonomy rather than limiting it. Choice D is incorrect since patient advocacy goes beyond clinical procedures to encompass holistic care that addresses the patients' preferences and rights.

Correct Answer: C

Rationale: The correct answer is to determine the reasons the nurses are not taking scheduled breaks. This action is crucial as it allows the charge nurse to understand the underlying causes for the behavior. By identifying the reasons, the nurse can then address the root of the issue effectively. Option A is incorrect because discussing time management strategies may not address the specific reasons for not taking breaks. Option B is incorrect as providing coverage for breaks does not address the underlying cause of the issue. Option D is also incorrect as reviewing policies should come after understanding the reasons for the behavior.

Correct Answer: B

Rationale: The best argument for lower patient-to-nurse ratios is that they decrease patient mortality. Choice A is incorrect because having more patients can lead to increased workload and decreased attention per patient. Choice C is incorrect as adequate nurse levels can indeed impact the prevalence of infections. Choice D is incorrect as community nursing ratios can impact MRSA rates due to potential transmission risks in healthcare settings.

Correct Answer: C

Rationale: Idiopathic thrombocytopenic purpura is a bleeding disorder characterized by a low number of platelets in the blood. This condition is not highly similar to disseminated intravascular coagulation (DIC), which involves abnormal clotting throughout the body (coagulation), leading to depletion of platelets. Choice B is incorrect because idiopathic thrombocytopenic purpura is actually characterized by a decrease in platelet count, not an overproduction. While immune system-boosting medications may be used in some cases, the primary treatment for idiopathic thrombocytopenic purpura focuses on increasing platelet counts or managing symptoms.

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.
