A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?
- A. Stimulates insulin secretion from the pancreas.
- B. Increases insulin sensitivity in various tissues.
- C. Decreases hepatic glucose production.
- D. Delays absorption of glucose from the intestines.
Correct Answer: C
Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.

After placing a client at 26-weeks gestation in the lithotomy position, the client complains of dizziness and becomes pale and diaphoretic. What action should the nurse implement?
- A. Instruct the client to take deep breaths.
- B. Place a wedge under the client's hip.
- C. Place the client in the Trendelenburg position.
- D. Remove the client's legs from the stirrups.
Correct Answer: B
Rationale: Placing a wedge under the client's hip is the correct action in this scenario. This helps relieve the pressure on the vena cava, which can become compressed in the lithotomy position during pregnancy, improving circulation and reducing symptoms like dizziness and pallor. Instructing the client to take deep breaths (Choice A) may not address the underlying cause of the symptoms. Placing the client in the Trendelenburg position (Choice C) would worsen the situation by further compressing the vena cava. Removing the client's legs from the stirrups (Choice D) may provide temporary relief but does not address the root cause of the issue.
A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important assessment before administering this medication?
- A. Check blood pressure.
- B. Assess heart rate.
- C. Monitor respiratory rate.
- D. Measure oxygen saturation.
Correct Answer: B
Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.
A healthcare provider is conducting a health education session about the prevention of type 2 diabetes. What lifestyle modification should be emphasized?
- A. Increasing physical activity
- B. Reducing dietary sugar intake
- C. Regular health screenings
- D. All of the above
Correct Answer: D
Rationale: To effectively prevent type 2 diabetes, individuals should focus on a combination of lifestyle modifications. Increasing physical activity helps maintain a healthy weight and improves insulin sensitivity. Reducing dietary sugar intake can lower the risk of developing diabetes by managing blood sugar levels. Regular health screenings are crucial for early detection and timely intervention. Emphasizing all these modifications together provides a comprehensive approach to diabetes prevention. Choices A, B, and C are all important components of a healthy lifestyle that can contribute to reducing the risk of type 2 diabetes.
During a home visit, a nurse finds that an elderly client is having trouble remembering to take their medications. What is the best intervention?
- A. Set up a pill organizer
- B. Involve family members in care
- C. Arrange for a home health aide
- D. Implement all of the above
Correct Answer: D
Rationale: The best intervention when an elderly client is having trouble remembering to take their medications is to implement all of the above options. Setting up a pill organizer helps in organizing and remembering medication schedules. Involving family members in care ensures additional support and reminders. Arranging for a home health aide can provide direct assistance and supervision. Implementing all these strategies together can significantly improve medication adherence, especially in clients with memory issues. Each option plays a crucial role in addressing different aspects of the problem, making 'Implement all of the above' the most comprehensive and effective choice.
The nurse is assessing a client who has been diagnosed with chronic obstructive pulmonary disease (COPD). Which clinical finding is characteristic of this condition?
- A. Pursed-lip breathing
- B. Hyperresonance on percussion
- C. Bradycardia
- D. High-pitched inspiratory crackles
Correct Answer: A
Rationale: Pursed-lip breathing is a characteristic finding in clients with COPD. It helps keep the airways open during exhalation, acting as a compensatory mechanism to prevent airway collapse, which is common in COPD. Hyperresonance on percussion is typically found in conditions like emphysema, which is a component of COPD but not characteristic of the overall disease. Bradycardia is not typical in COPD; instead, clients often exhibit tachycardia due to chronic hypoxemia. High-pitched inspiratory crackles are more commonly associated with conditions like pneumonia, not COPD.
