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 diabetes exhibits a blood sugar of 350 mg/dL. What is the nurse's best action?
- A. Administer insulin as prescribed
- B. Provide a carbohydrate-controlled snack
- C. Encourage physical activity
- D. Recheck the blood sugar
Correct answer: A
Rationale: In a client with diabetes presenting with a blood sugar level of 350 mg/dL, the best action for the nurse is to administer insulin as prescribed. High blood sugar levels can lead to complications like diabetic ketoacidosis, making prompt insulin administration crucial to lower the blood glucose level. Providing a carbohydrate-controlled snack would be inappropriate as it may further elevate blood sugar levels. Encouraging physical activity is not advisable when the blood sugar is significantly high, as exercise can raise blood sugar levels. Rechecking the blood sugar is necessary after administering insulin to monitor the response to treatment.
3. Based on the Nursing diagnosis of 'Potential for infection related to second and third degree burns,' which intervention has the highest priority?
- A. Application of topical antibacterial cream
- B. Use of careful hand washing technique
- C. Administration of plasma expanders
- D. Limiting visitors to the burned client
Correct answer: B
Rationale: The highest priority intervention in this scenario is B, the use of careful hand washing technique. Proper hand hygiene is essential in preventing infection, especially in individuals with compromised skin integrity like those with burns. By practicing careful hand washing, healthcare providers reduce the risk of introducing harmful pathogens to the burn wound, thus lowering the chances of infections. Choice A, application of topical antibacterial cream, is important but should follow ensuring proper hand hygiene. Choice C, administration of plasma expanders, is not directly associated with preventing burn-related infections. Choice D, limiting visitors, is significant for infection control, but ensuring proper hand hygiene outweighs this intervention in terms of priority.
4. The nurse is monitoring a client with an IV infusion in the left antecubital fossa. The site is warm, red, and without swelling. What conclusion should the nurse draw from these findings?
- A. The IV fluids are infusing into the subcutaneous tissues
- B. The infusion pump is functioning properly
- C. The insertion date should be verified and the IV discontinued
- D. The site is inflamed and should be reported
Correct answer: B
Rationale: The correct answer is B. Warmth and redness at the IV site without swelling indicate a localized reaction, which is common and does not necessarily indicate infiltration of IV fluids into the subcutaneous tissues. The absence of swelling suggests that the IV is correctly placed. Therefore, the nurse should conclude that the infusion pump is functioning properly. Choice A is incorrect as warmth and redness alone do not indicate subcutaneous infiltration. Choice C is incorrect as discontinuing the IV solely based on warmth and redness without swelling is not necessary. Choice D is incorrect as the absence of swelling signifies a localized reaction rather than inflammation requiring immediate reporting.
5. During a routine prenatal visit, a nurse measures a client’s fundal height at 26 weeks gestation. What should the fundal height be?
- A. Approximately 26 cm
- B. Between 24 to 28 cm
- C. Above the umbilicus by two finger widths
- D. Below the xiphoid process
Correct answer: B
Rationale: The correct answer is B: 'Between 24 to 28 cm.' Fundal height is expected to be approximately equal to the weeks of gestation, so at 26 weeks, the fundal height should typically range between 24 to 28 cm. Choice A is incorrect because fundal height is not an exact measurement of gestational age in centimeters. Choice C is incorrect as it provides a general description above the umbilicus, which is not specific to 26 weeks gestation. Choice D is incorrect as the fundal height would not reach below the xiphoid process at 26 weeks gestation.
