Which of the following is responsible for the rhythm and quality of breathing?
- A. Medulla oblongata
- B. Pons
- C. Carotid bodies
- D. Aortic bodies
Correct Answer: A
Rationale: The medulla oblongata's respiratory center sets breathing rhythm and depth e.g., 12-20 breaths/min via dorsal and ventral groups. Pons refines, carotid/aortic bodies adjust via chemo input. Nurses assess this e.g., in COPD for foundational respiratory function, per neurophysiology.

A client with pancreatitis is being taught about dietary management. Which of the following statements by the client indicates an understanding of the teaching?
- A. I should increase my intake of high-fat foods.
- B. I should decrease my intake of high-fat foods.
- C. I should increase my intake of high-protein foods.
- D. I should decrease my intake of high-protein foods.
Correct Answer: B
Rationale: The correct answer is B. Decreasing the intake of high-fat foods is essential in managing pancreatitis as high-fat foods can exacerbate symptoms and lead to complications. By reducing high-fat foods in their diet, the client demonstrates an understanding of the dietary management needed for pancreatitis. Choices A, C, and D are incorrect. Increasing high-fat foods (Choice A) is not recommended for pancreatitis as it can worsen the condition. While high-protein foods (Choice C) can be beneficial in some cases, the primary focus in pancreatitis management is on reducing fat intake. Decreasing high-protein foods (Choice D) is not a key dietary management approach for pancreatitis.
A client with a traumatic brain injury is receiving mannitol. The nurse should monitor for which adverse effect of this medication?
- A. Hypotension
- B. Hyperkalemia
- C. Hyperglycemia
- D. Bradycardia
Correct Answer: A
Rationale: Mannitol, an osmotic diuretic, can cause hypotension (A) from fluid shifts and diuresis. Hyperkalemia (B), hyperglycemia (C), or bradycardia (D) are less common. A is correct. Rationale: BP drop risks perfusion; monitoring ensures safety, per pharmacology, critical in brain injury management.
What is the primary purpose of repositioning a patient who is immobile?
- A. To prevent pressure ulcers
- B. To promote joint flexibility
- C. To increase muscle strength
- D. To improve respiratory function
Correct Answer: A
Rationale: Repositioning an immobile patient primarily aims to prevent pressure ulcers by relieving pressure on skin over bony areas, like the sacrum or heels, and enhancing blood flow. Prolonged immobility risks tissue breakdown due to constant compression, making regular movement a cornerstone of preventive care in nursing. While shifting positions can secondarily support joint mobility, this isn't the main goal specific exercises target that more effectively. Building muscle strength requires active effort beyond repositioning, and though respiratory benefits may occur, they're addressed through targeted interventions like breathing exercises. This focus on skin integrity reflects nursing's priority to mitigate a common, severe complication of immobility, ensuring patient safety and comfort through proactive care.
A client reports difficulty sleeping at night, which interferes with daily functioning. Which intervention should the nurse suggest to this client?
- A. Avoid beverages containing caffeine
- B. Take a sleep medication regularly at bedtime
- C. Watch television for 30 minutes in bed to relax before falling asleep
- D. Advise the client to take several naps during the day
Correct Answer: A
Rationale: The correct answer is A: Avoid beverages containing caffeine. Caffeine is a stimulant that can interfere with sleep, making it difficult for the client to fall asleep at night. Taking sleep medication regularly (choice B) may not address the root cause of the sleep difficulty and can lead to dependency. Watching television in bed (choice C) can actually stimulate the brain and hinder relaxation before sleep. Advising the client to take several naps during the day (choice D) can disrupt the sleep-wake cycle further. Therefore, recommending the avoidance of caffeine-containing beverages is the most appropriate intervention to help the client improve their ability to sleep at night and function better during the day.
Which of the following is NOT true about post mortem care?
- A. The body should be placed in a morgue within 1 hour
- B. Wash hands before and after care
- C. Remove tubes and soiled linens
- D. Close the eyes and mouth
Correct Answer: A
Rationale: Body to morgue within 1 hour (A) isn't true no strict universal timing, per facility policy. Hand washing (B), tube removal (C), and closing eyes/mouth (D) are standard. A's rigidity misaligns with flexible care, making it untrue.
