1. Which cells in the islet of the pancreas are responsible for synthesizing insulin?
- A. Alpha cells
- B. Beta cells
- C. Gamma cells
- D. Delta cells
Correct answer: B
Rationale: Beta cells in the islets of Langerhans in the pancreas are responsible for the production and secretion of insulin, which is crucial for regulating blood glucose levels. Alpha cells, on the other hand, produce glucagon, a hormone that raises blood glucose levels. Gamma cells and Delta cells do not exist in the islets of Langerhans; therefore, they are incorrect choices.
2. Which topical antimicrobial is most frequently used in burn wound care?
- A. Neosporin
- B. Silver nitrate
- C. Silver sulfadiazine
- D. Sulfamylon
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
3. Much of the research investigating probiotics and intestinal illness has focused on the prevention and treatment of _____.
- A. irritable bowel syndrome
- B. Crohn's disease
- C. diverticulitis
- D. infectious diarrhea
Correct answer: D
Rationale: The correct answer is 'D: infectious diarrhea.' Research has extensively explored the use of probiotics in the prevention and treatment of infectious diarrhea. Probiotics can aid in restoring the balance of gut flora, thereby reducing symptoms. Choices A, B, and C are incorrect because while probiotics may have some benefits for these conditions, the primary focus of research in relation to probiotics and intestinal illness has been on infectious diarrhea.
4. What level of sodium restriction would be included as part of nutrition therapy for heart failure?
- A. Less than 500 mg per day
- B. 1000 mg to 1500 mg per day
- C. 1500 mg to 3000 mg per day
- D. 3000 to 3500 mg per day
Correct answer: C
Rationale: The correct answer is 1500 mg to 3000 mg per day. This is the level of sodium restriction typically recommended for heart failure patients. It helps manage fluid retention and reduce blood pressure, which are both crucial in treating heart failure. A sodium intake of less than 500 mg per day (Choice A) might be too restrictive and is not typically recommended. Similarly, an intake of 1000 mg to 1500 mg per day (Choice B) falls short of the recommended range. Lastly, an intake of 3000 to 3500 mg per day (Choice D) exceeds the recommended upper limit, potentially exacerbating fluid retention and high blood pressure.
5. Selective inattention is seen in which level of anxiety?
- A. Mild
- B. Moderate
- C. Severe
- D. Panic
Correct answer: D
Rationale: Selective inattention is a defense mechanism seen in panic-level anxiety. In panic anxiety, individuals may experience selective inattention, where they focus only on specific aspects and ignore others. Mild anxiety does not typically involve selective inattention as individuals can still function effectively. Moderate and severe anxiety may impair attention, but selective inattention is more characteristic of panic-level anxiety.
