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 9-year-old is receiving vancomycin 400 mg IV every 6 hours for a methicillin-resistant (Beta-lactam-resistant) Staphylococci aureus (MRSA) infection. The medication is diluted in a 100 mL bag of saline with instructions to infuse over one and a half hours. How many mL/hour should the nurse program the infusion pump?

• A. 50
• B. 67
• C. 57
• D. 70

Correct answer: B

Rationale: To calculate the infusion rate for vancomycin, you need to divide the total volume by the total time of infusion. In this case, the total volume is 100 mL, and the total time is 1.5 hours. Therefore, 100 mL ÷ 1.5 hours = 67 mL/hour. This means the nurse should program the infusion pump to deliver vancomycin at a rate of 67 mL/hour. Choice A (50) is incorrect as it does not reflect the correct calculation. Choice C (57) is incorrect as it is not the accurate calculation based on the provided information. Choice D (70) is incorrect as it does not correspond to the correct infusion rate calculation.

3. A client with a cast complains of numbness and tingling in the affected limb. What should the nurse do first?

• A. Check for tightness of the cast
• B. Elevate the limb
• C. Apply ice to the area
• D. Notify the physician

Correct answer: A

Rationale: The correct first action for a client with a cast experiencing numbness and tingling in the affected limb is to check for tightness of the cast. Numbness and tingling can indicate compromised circulation, and a tight cast may be causing this. Checking the cast for tightness is essential to ensure it is not impeding circulation. Elevating the limb, applying ice, or notifying the physician can be subsequent actions depending on the assessment findings after checking the cast. Elevating the limb might help improve circulation, applying ice is not indicated for numbness and tingling, and notifying the physician can be done if the issue persists after addressing the immediate concern of cast tightness.

4. A client with a history of hypertension is prescribed lisinopril. Which potential side effect should the nurse monitor for?

• A. Hypokalemia
• B. Hyperglycemia
• C. Persistent cough
• D. Tachycardia

Correct answer: C

Rationale: The correct answer is C: Persistent cough. Lisinopril is an ACE inhibitor commonly associated with a persistent dry cough as a side effect. This cough is thought to result from increased bradykinin levels. Choices A, B, and D are incorrect. Hypokalemia is not a common side effect of lisinopril; in fact, it may lead to hyperkalemia. Hyperglycemia is not a typical side effect of lisinopril use. Tachycardia is also not a common side effect associated with ACE inhibitors like lisinopril.

5. During a bed bath, the nurse observes that a client's IV site is red and swollen. What should the nurse do first?

• A. Discontinue the IV under physician's guidance
• B. Apply a warm compress to the site
• C. Notify the physician
• D. Document the appearance of the site and continue the bath

Correct answer: C

Rationale: The correct first action when a nurse observes a red and swollen IV site during a bed bath is to notify the physician. This is crucial because prompt reporting allows for immediate intervention to prevent further complications. Discontinuing the IV (Choice A) should only be done under the physician's guidance to avoid any adverse effects and ensure proper care. Applying a warm compress (Choice B) may not address the underlying issue and could potentially worsen the situation if the cause is an infection or infiltration. Documenting the site's appearance and continuing the bath (Choice D) without immediate action might delay necessary treatment, leading to potential complications.
