Biology Test
1. Which of the following organelles is known as the cell's digestion center?
- A. Chloroplasts
- B. Mitochondria
- C. Lysosomes
- D. Ribosomes
Correct answer: C
Rationale: The correct answer is C: Lysosomes. Lysosomes contain enzymes that break down waste materials and cellular debris within the cell, making them the cell's digestion center. Choice A, Chloroplasts, are responsible for photosynthesis. Choice B, Mitochondria, are the powerhouse of the cell, generating energy. Choice D, Ribosomes, are involved in protein synthesis. Therefore, Lysosomes are specifically known for their role in digestion within the cell.
2. What is the nurse manager’s role in improving the quality of care on the unit?
- A. The nurse manager is responsible for setting goals and priorities for the unit and ensuring that staff members are working towards achieving those goals.
- B. The nurse manager is responsible for monitoring patient outcomes and implementing changes to improve the quality of care on the unit.
- C. The nurse manager is responsible for ensuring that staff members follow established procedures and protocols to maintain the quality of care on the unit.
- D. The nurse manager is responsible for providing feedback and coaching to staff members to help them improve their performance and achieve the unit’s quality goals.
Correct answer: A
Rationale: The nurse manager plays a crucial role in improving the quality of care on the unit by setting goals and priorities for the unit and ensuring that staff members are working towards achieving those goals. This involves strategic planning, coordination, and leadership to guide the team in delivering high-quality patient care. Option B is incorrect as while monitoring patient outcomes is important, it is not the primary role of the nurse manager in improving care quality. Option C is incorrect because while ensuring staff adherence to procedures is important, it is a part of maintaining quality rather than actively improving it. Option D is incorrect as providing feedback and coaching, though essential, is not the primary role of the nurse manager in setting goals and priorities for quality improvement.
3. A client is prescribed metformin for type 2 diabetes. What should the nurse emphasize in the client's teaching?
- A. Take the medication with meals to reduce the risk of GI upset.
- B. Report any muscle pain to the healthcare provider promptly.
- C. Avoid alcohol consumption while taking this medication.
- D. Monitor blood sugar levels regularly to prevent hypoglycemia.
Correct answer: C
Rationale: The correct answer is to avoid alcohol consumption while taking metformin. Alcohol can increase the risk of lactic acidosis when combined with metformin. Choice A is incorrect because metformin is usually recommended to be taken with meals to reduce GI upset. Choice B is important but not the priority; muscle pain is more commonly associated with other diabetes medications. Choice D is incorrect because metformin typically does not cause hypoglycemia but rather helps control blood sugar levels in type 2 diabetes.
4. A client with a history of heart failure is admitted with severe dyspnea. Which laboratory result requires immediate intervention?
- A. Blood glucose of 150 mg/dL.
- B. Serum potassium of 3.5 mEq/L.
- C. Serum creatinine of 1.0 mg/dL.
- D. Blood urea nitrogen (BUN) of 20 mg/dL.
Correct answer: C
Rationale: The correct answer is C. A serum creatinine level of 1.0 mg/dL is within the normal range. However, in a client with heart failure and severe dyspnea, fluid retention is a significant concern. An elevated serum creatinine level may indicate impaired kidney function, which can worsen fluid overload. Therefore, immediate intervention is required to prevent further complications. Choices A, B, and D are within normal ranges and not indicative of immediate intervention in this scenario.
5. The nurse is managing the care of a client with Cushing's syndrome. Which interventions should the nurse delegate to the UAP?
- A. Report any client complaint of pain or discomfort
- B. Weigh the client and report any weight gain
- C. Note and report the client's food and liquid intake during meals and snacks
- D. All of the above
Correct answer: D
Rationale: The UAP can be tasked with reporting complaints, monitoring weight gain, and tracking food and fluid intake, all of which are important in managing a client with Cushing's syndrome. These tasks fall within the UAP's scope of practice. Reporting client complaints helps in early identification of complications, monitoring weight is crucial due to fluid retention in Cushing's syndrome, and tracking food and fluid intake assists in dietary management. Choices A, B, and C are all necessary components of care for a client with Cushing's syndrome, making option D the correct answer.
