Nursing Elites

1. What is the approximate duration of action for intermediate-acting insulins like NPH?

• A. 6-8 hours.
• B. 10-14 hours.
• C. 16-20 hours.
• D. 24-28 hours.

Correct answer: C

Rationale: The correct answer is C: '16-20 hours.' Intermediate-acting insulins like NPH typically have a duration of action of approximately 16-20 hours. This prolonged action makes them effective in managing blood glucose levels over an extended period. Choices A, B, and D are incorrect because they do not align with the typical duration of action for intermediate-acting insulins. Choice A (6-8 hours) is too short, choice B (10-14 hours) is also shorter than the typical duration, and choice D (24-28 hours) is too long for intermediate-acting insulins like NPH.

2. The client with newly diagnosed diabetes mellitus is receiving education from the nurse on managing blood glucose levels. Which statement indicates a need for further teaching?

• A. I will monitor my blood glucose levels regularly.
• B. I can eat whatever I want as long as I take my medication.
• C. I should exercise regularly to help control my blood sugar.
• D. I will rotate my injection sites to avoid tissue damage.

Correct answer: B

Rationale: Choice B indicates a need for further teaching because it suggests that the client can eat whatever they want as long as they take their medication, which is incorrect. Clients with diabetes mellitus need to follow a healthy and balanced diet in addition to taking their medication to effectively manage blood glucose levels. Choices A, C, and D are correct statements for managing diabetes. Monitoring blood glucose levels regularly, engaging in regular exercise to help control blood sugar, and rotating injection sites to avoid tissue damage are all important aspects of diabetes management.

3. A client with DM is scheduled to have surgery. The nurse should plan to:

• A. Give the client a regular diet as ordered.
• B. Hold the client's insulin on the morning of surgery.
• C. Monitor the client's blood glucose level closely during the perioperative period.
• D. Have the client stop taking insulin 48 hours before surgery.

Correct answer: C

Rationale: The correct answer is to monitor the client's blood glucose level closely during the perioperative period. This is essential to ensure that the client's blood glucose levels remain within the target range and to prevent complications such as hypo- or hyperglycemia. Choices A, B, and D are incorrect because giving a regular diet as ordered, holding insulin on the morning of surgery, or stopping insulin 48 hours before surgery can lead to uncontrolled blood glucose levels, posing risks to the client's safety during the surgical procedure.

4. A client with type 1 diabetes mellitus presents with nausea, vomiting, and abdominal pain. The nurse suspects diabetic ketoacidosis (DKA). Which of the following lab findings would confirm this diagnosis?

• A. Serum glucose of 180 mg/dL
• B. Serum bicarbonate of 22 mEq/L
• C. Blood pH of 7.25
• D. Urine specific gravity of 1.020

Correct answer: C

Rationale: A blood pH of 7.25 is a critical finding in diabetic ketoacidosis (DKA) as it indicates metabolic acidosis, which is a hallmark of this condition. In DKA, there is an accumulation of ketones in the blood, leading to increased acidity. The serum glucose level is typically elevated in DKA, often exceeding 250 mg/dL. A serum bicarbonate level less than 18 mEq/L is usually seen in DKA due to the metabolic acidosis. Urine specific gravity is not a specific indicator for DKA and may vary depending on the individual's hydration status. Therefore, the correct lab finding that confirms DKA in this scenario is a blood pH of 7.25.

5. Nurse Kate is providing dietary instructions to a male client with hypoglycemia. To control hypoglycemic episodes, the nurse should recommend:

• A. Increasing saturated fat intake and fasting in the afternoon
• B. Increasing intake of vitamins B and D and taking iron supplements
• C. Eating a candy bar if lightheadedness occurs
• D. Consuming a low-carbohydrate, high-protein diet and avoiding fasting

Correct answer: D

Rationale: A low-carbohydrate, high-protein diet is beneficial for individuals with hypoglycemia as it helps in maintaining stable blood sugar levels. Choice A is incorrect as increasing saturated fat intake and fasting can worsen hypoglycemia. Choice B is incorrect as vitamins and iron supplements do not directly address hypoglycemia. Choice C is incorrect as consuming a candy bar may provide temporary relief but does not address the underlying cause of hypoglycemia.
