Correct Answer: C

Rationale: No metal objects may be worn while receiving magnetic resonance imaging due to safety risks involved with the strong magnet. The correct response by the nurse should prioritize the safety of the client. Allowing the client to wear the metal crucifix poses a risk of injury or interference with the imaging process. Option A is not appropriate as safety takes precedence over comfort in this situation. Option B is incorrect as it does not address the safety concerns associated with wearing metal objects during an MRI. Option D is also incorrect as it fails to acknowledge the safety issue involved and instead focuses solely on the importance to the client. It is important for the nurse to offer alternative forms of spiritual support that do not pose a risk during the MRI procedure.

Correct Answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.

Correct Answer: B

Rationale: The correct answer is 'serving as the expert for resource utilization.' While physicians play a crucial role in case management, their primary focus is on medical diagnosis and treatment rather than resource utilization. Choices A, C, and D are all roles that physicians typically fulfill in case management. A physician participating in interdisciplinary planning for clients ensures comprehensive care, consulting with the case management team helps in coordinating timely orders, and contributing to the documentation of a client's needs for services aids in providing appropriate care. Therefore, serving as the expert for resource utilization does not align with the primary responsibilities of a physician in case management.

Correct Answer: A

Rationale: When providing perineal care to a female client, the nurse should wear gloves and wash the perineal area from front to back. This technique helps prevent the introduction of E. coli and other bacteria into the urethra, reducing the risk of urinary tract infections. Washing from back to front can introduce bacteria from the anal area to the urethra, leading to infections. Performing the procedure without gloves or having the client perform all care does not adhere to infection control practices. Pouring water from a sterile bottle alone may not ensure proper cleansing and infection prevention. Therefore, choices B, C, and D are incorrect as they do not follow proper perineal care guidelines.

Correct Answer: A

Rationale: The correct action for a client with major head trauma receiving bolus enteral feeding is to measure intake and output (I&O). Enteral feedings are hyperosmotic agents that can cause fluid shifts. Monitoring I&O is crucial to assess fluid balance, ensuring that input matches output. Checking albumin levels (choice B) is important for assessing nutritional status but is not the immediate priority in this situation. Monitoring glucose levels (choice C) is also important but not as critical as measuring I&O in this context. Increasing enteral feeding (choice D) should only be done based on a healthcare provider's order after assessing the patient's condition, not as the most important nursing order at this time.
