Nursing Elites

1. 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.

2. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with shortness of breath. What is the priority nursing intervention?

• A. Administer a high-flow oxygen mask.
• B. Position the client in a high-Fowler's position.
• C. Provide a high-carbohydrate diet.
• D. Encourage the client to cough and deep breathe.

Correct answer: B

Rationale: The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and breathing by reducing respiratory effort. Administering a high-flow oxygen mask (Choice A) may be necessary but is not the priority intervention. Providing a high-carbohydrate diet (Choice C) is not directly related to managing acute shortness of breath in COPD. Encouraging the client to cough and deep breathe (Choice D) is helpful for airway clearance but is not the priority intervention when the client is in distress with acute shortness of breath.

3. A client with a diagnosis of chronic heart failure is prescribed 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. Digoxin can lead to bradycardia, making it crucial to evaluate the heart rate to prevent potential complications. Checking blood pressure (Choice A) is important but not as critical as assessing the heart rate in this context. Monitoring respiratory rate (Choice C) and measuring oxygen saturation (Choice D) are not the most crucial assessments before administering digoxin, as the primary concern with this medication is its impact on heart rate.

4. An elderly client is concerned about constipation during a flight. What should the nurse recommend?

• A. Use an over-the-counter stool softener when needed
• B. Eat a high protein diet
• C. Increase the fluid intake in the diet
• D. Decrease the fat content in the diet

Correct answer: C

Rationale: The correct answer is to recommend increasing fluid intake in the diet. Adequate hydration is essential for preventing constipation, especially during travel when mobility may be reduced. Stool softeners are not the first-line recommendation and should only be used when necessary. Eating a high protein diet or decreasing fat content in the diet may not directly address the issue of constipation related to dehydration during a flight.

5. A client has a prescription for a Transcutaneous Electrical Nerve Stimulator (TENS) unit for pain management during the postoperative period following a Lumbar Laminectomy. What information should the nurse reinforce about the action of this adjuvant pain modality?

• A. Mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
• B. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
• C. An infusion of medication in the spinal canal will block pain perception
• D. The discharge of electricity will distract the client's focus on the pain

Correct answer: A

Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.
