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.

Which of the following statement is NOT true about safety protocols?
- A. Reduce harm
- B. Guide care
- C. Only for emergencies
- D. Part of nursing

Rationale: Safety protocols reduce harm (A), guide care (B), are nursing (D) 'only for emergencies' (C) isn't true, used always, per standards. C's limit contradicts broad use, like Mr. Gary's routine care, making it untrue.
A client with chronic kidney disease is being educated by a nurse about dietary management. Which of the following statements by the client indicates an understanding of the teaching?
- A. I should limit my intake of protein to prevent overworking my kidneys.
- B. I should increase my intake of potassium-rich foods.
- C. I should increase my intake of phosphorus-rich foods.
- D. I should increase my intake of calcium-rich foods.
Correct Answer: A
Rationale: The correct answer is A. In chronic kidney disease, limiting protein intake is crucial to prevent overworking the kidneys. Excessive protein consumption can lead to the accumulation of metabolic waste products that the kidneys struggle to process, worsening kidney function. Therefore, by recognizing the need to restrict protein intake, the client demonstrates an understanding of the dietary management required for their condition. Choices B, C, and D are incorrect. Increasing intake of potassium-rich foods (Choice B) is not recommended in chronic kidney disease as it can lead to hyperkalemia. Similarly, increasing intake of phosphorus-rich foods (Choice C) is not advised because impaired kidneys struggle to excrete phosphorus, leading to elevated levels in the blood. Lastly, increasing intake of calcium-rich foods (Choice D) may not be necessary unless there is a specific deficiency or requirement, as calcium balance is often disrupted in chronic kidney disease.
A client has major fecal incontinence and reports irritation in the perianal area. Which of the following actions should the nurse take first?
- A. Apply a fecal collection system
- B. Apply a barrier cream
- C. Cleanse and dry the area
- D. Check the client's perineum
Correct Answer: D
Rationale: When a client with major fecal incontinence reports irritation in the perianal area, the nurse's initial action should be to assess the client's perineum to gather more information. By checking the perineum, the nurse can identify the extent and nature of the irritation, allowing for appropriate interventions to be initiated. This assessment is crucial in developing a comprehensive care plan and addressing the client's immediate needs effectively. Applying the nursing process priority-setting framework helps in planning care and prioritizing nursing actions, making assessment the initial step in this scenario. Applying a fecal collection system (choice A) would be premature without assessing the perineal area first. Similarly, applying a barrier cream (choice B) or cleansing and drying the area (choice C) should follow the assessment to ensure appropriate interventions are chosen based on the assessment findings.
A healthcare professional is planning care for a client who has a new prescription for a low-sodium diet. Which of the following foods should the healthcare professional recommend?
- A. Canned soup
- B. Fresh fruit
- C. Pickles
- D. Soy sauce
Correct Answer: B
Rationale: Fresh fruit is naturally low in sodium and is a suitable choice for a low-sodium diet. It provides essential nutrients without adding significant amounts of sodium, making it a healthy option for individuals following a low-sodium diet. Canned soup, pickles, and soy sauce are high in sodium content and should be avoided by individuals on a low-sodium diet. Canned soups are often loaded with added salt, pickles are preserved in brine containing high sodium levels, and soy sauce is a condiment with a high sodium content.
