Nursing Elites

1. Dr. Kennedy prescribes glipizide (Glucotrol), an oral antidiabetic agent, for a male client with type 2 diabetes mellitus who has been having trouble controlling the blood glucose level through diet and exercise. Which medication instruction should the nurse provide?

• A. Be sure to take glipizide 30 minutes before meals.
• B. Glipizide may cause a low serum sodium level, so make sure you have your sodium level checked monthly.
• C. You won't need to check your blood glucose level after you start taking glipizide.
• D. Take glipizide after a meal to prevent heartburn.

Correct answer: A

Rationale: Glipizide should be taken 30 minutes before meals to maximize its glucose-lowering effect.

2. A client with DM is being taught about the importance of foot care by a nurse. Which instruction should the nurse include?

• A. Use a heating pad to warm your feet.
• B. Avoid walking barefoot.
• C. Soak your feet in hot water every night.
• D. Wear tight shoes to protect your feet.

Correct answer: B

Rationale: The correct instruction for the nurse to include is to advise the client to avoid walking barefoot. This recommendation is crucial for clients with diabetes to prevent foot injuries and infections. Walking barefoot can lead to unnoticed wounds or ulcers due to reduced sensation in the feet (neuropathy) common in diabetes. Choice A is incorrect as heating pads can cause burns and should be avoided. Choice C is incorrect because soaking feet in hot water can also lead to burns and skin damage. Choice D is incorrect as tight shoes can increase the risk of pressure sores and restrict blood flow, which is detrimental for individuals with diabetes.

3. 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.

4. The client has undergone a thyroidectomy. Which of the following symptoms would indicate a potential complication?

• A. Bradycardia
• B. Tachycardia
• C. Hyperreflexia
• D. Hypocalcemia

Correct answer: D

Rationale: Hypocalcemia is a potential complication of thyroidectomy as it may occur if the parathyroid glands, responsible for calcium regulation, are inadvertently removed or damaged during the procedure. Bradycardia (slow heart rate) is not typically associated with thyroidectomy complications. Tachycardia (fast heart rate) is more commonly seen in hyperthyroidism. Hyperreflexia (exaggerated reflex responses) is not a typical complication of thyroidectomy.

5. A nurse caring for a client with hypocalcemia would expect to note which of the following changes on the electrocardiogram?

• A. Widened T wave
• B. Prominent U wave
• C. Prolonged QT interval
• D. Shortened ST segment

Correct answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.
