Correct Answer: C

Rationale: The correct action for the nurse to take is to ask the client's son to go to the waiting area. This allows the nurse to interview the client independently to assess for signs of elder abuse without the son's potential influence. Filing an incident report may be necessary later but is not the immediate action required. Asking about injuries with the son present could lead to biased responses or intimidation. Treating and discharging the client without addressing the suspicion of elder abuse would neglect the nurse's responsibility to ensure the client's safety.

Correct Answer: B

Rationale: Patient confidentiality is significant in healthcare because it involves protecting patient privacy. Maintaining confidentiality ensures that patients feel safe and secure when sharing sensitive information with healthcare providers. Choice A is incorrect because sharing patient information freely would violate confidentiality. Choice C is incorrect because ignoring patient consent goes against ethical principles. Choice D is incorrect because limiting patient access to their own records does not relate directly to the concept of patient confidentiality.

Correct Answer: D

Rationale: Pouching a new colostomy is a task that can be safely and appropriately delegated to an assistive personnel as it falls within their scope of practice. Measuring oxygen saturation (Choice A) requires a higher level of training and assessment, making it unsuitable for delegation. Inserting a rectal suppository (Choice B) and performing nasal hygiene (Choice C) involve invasive procedures that are typically performed by licensed nursing staff due to the associated risks and complexities, making them inappropriate for delegation to assistive personnel.

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.
