1. Which type of cells secrete insulin?
- A. alpha cells
- B. beta cells
- C. CD4 cells
- D. helper cells
Correct answer: B
Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.
2. Which of the following observations is most important when assessing a client's breathing?
- A. presence of breathing and pulse rate
- B. breathing pattern and adequacy of breathing
- C. presence of breathing and adequacy of breathing
- D. patient position and adequacy of breathing
Correct answer: C
Rationale: The correct answer is the presence of breathing and adequacy of breathing. It is crucial not only to confirm that the client is breathing but also to ensure that the breathing is adequate for proper oxygenation. Choices A, B, and D are incorrect because while pulse rate, breathing pattern, and patient position are relevant aspects to consider, the most critical observations in assessing a client's breathing are the presence and adequacy of breathing.
3. Which of the following injuries, if demonstrated by a client entering the Emergency Department, is the highest priority?
- A. open leg fracture
- B. open head injury
- C. stab wound to the chest
- D. traumatic amputation of a thumb
Correct answer: C
Rationale: A stab wound to the chest might result in lung collapse and mediastinal shift that, if untreated, could lead to death. Treatment of an obstructed airway or a chest wound is a higher priority than hemorrhage. The principle of ABC (airway, breathing, and circulation) prioritizes care decisions. In this scenario, the stab wound to the chest poses the highest risk to the client's life as it can lead to severe complications such as lung collapse and mediastinal shift. Addressing this injury promptly is crucial to prevent further harm or potential fatality. Open leg fracture, open head injury, and traumatic amputation of a thumb, while serious, do not pose an immediate life-threatening risk compared to a stab wound to the chest.
4. What could be a possible cause for the symptoms experienced by the client in Question 28?
- A. iron deficiency
- B. folate deficiency
- C. peptic ulcer
- D. iron overload
Correct answer: A
Rationale: Given the client's symptoms of fatigue, shortness of breath, and lightheadedness, along with her gender and fad dieting, the most likely cause is iron deficiency. Iron deficiency commonly presents with these symptoms due to decreased oxygen-carrying capacity in the blood. Folate deficiency would typically present with different symptoms such as mouth sores and changes in skin, not fitting the client's presentation. Peptic ulcer would manifest with abdominal pain, not primarily with the symptoms described. Iron overload would present with symptoms such as joint pain and fatigue, which are not consistent with the client's presentation.
5. After a client has a tubal ligation in the outpatient surgical clinic, what is the priority for the nurse to determine?
- A. The client's prior experiences with outpatient surgery
- B. The client's medical plan and the extent of coverage for outpatient surgery
- C. The client's plan for transportation and care at home
- D. The client's plan to spend the night at the surgical center
Correct answer: C
Rationale: The priority for the nurse is to ensure the client has a safe way to get home and adequate care after discharge. It is crucial to determine the client's transportation arrangements and availability of care at home to ensure a smooth transition postoperatively. Options A and B, though important, are not immediate priorities compared to the client's safety and well-being after the procedure. Option D is incorrect as spending the night at the surgical center is not typically part of the plan for outpatient surgery.
