Correct Answer: C

Rationale: The correct action for the nurse to take in this situation is to ensure no visitors or staff enter the room for a short time period. Respecting the client's wish for privacy during emotional moments is crucial for providing patient-centered care. Contacting spiritual services or asking about the reason for crying may intrude on the client's privacy and emotional space. Turning on the television for a distraction is not appropriate as it does not address the client's emotional needs or request for privacy.

Correct Answer: A

Rationale: The correct answer is A. Secondary prevention aims to detect and address health issues early. Screening older adults in nursing care facilities for early influenza manifestations is an example of secondary prevention by identifying cases at an early stage. Choice B, promoting hand hygiene, is a form of primary prevention that aims to prevent the occurrence of influenza. Choice C, administering influenza vaccinations, is a form of primary prevention as well, focusing on preventing the disease before it occurs. Choice D, educating about healthy lifestyle choices, is more related to health promotion and primary prevention rather than secondary prevention.

Correct Answer: A

Rationale: The patellar reflex, also called the knee-jerk reflex, is elicited by tapping the patellar tendon just below the patella. This reflex involves the quadriceps muscle and the femoral nerve. The correct answer is 'A: Knee picture' because the patellar reflex is associated with the knee joint. Choices B, C, and D are incorrect as they do not correspond to the anatomical location involved in the patellar reflex.

Correct Answer: C

Rationale: The correct answer is C: Pain with passive movement. Pain with passive movement in a client with a new cast can indicate compartment syndrome, a serious condition where pressure builds up within the muscles, nerves, and blood vessels of the affected limb, potentially leading to tissue damage. Immediate reporting is crucial to prevent further complications. Increased warmth in the affected arm could be a normal inflammatory response to the injury and casting process. Itching under the cast is common and can be managed without immediate concern. Drainage on the cast may be expected initially after casting due to residual moisture from the setting process, but ongoing or excessive drainage should be monitored and reported if persistent.

Correct Answer: B

Rationale: The correct answer is B. Tightening the abdominal muscles before moving helps protect the back by providing core support. Keeping the legs straight (choice C) is incorrect as bending the legs is recommended to provide a stable base and prevent strain on the back. Twisting at the waist (choice D) while moving can cause back injury due to the strain on the spine. Placing the bed in the lowest position (choice A) is not directly related to preventing back strain during client repositioning, although it may be necessary for other reasons.
