1. The nurse is caring for a client with DM who is experiencing ketoacidosis. The nurse should prioritize which action?
- A. Administering insulin intravenously.
- B. Giving the client sips of water.
- C. Monitoring the client's urine output.
- D. Applying a heating pad to the client's abdomen.
Correct answer: A
Rationale: Administering insulin intravenously is the priority action for managing diabetic ketoacidosis. Insulin helps lower blood glucose levels and halts the production of ketones, addressing the underlying cause of ketoacidosis. Giving sips of water (Choice B) may be necessary for hydration, but it does not address the immediate life-threatening issue of ketoacidosis. Monitoring urine output (Choice C) is important for assessing renal function but is not the priority over administering insulin. Applying a heating pad (Choice D) is not indicated and can potentially worsen the condition in ketoacidosis.
2. A client with hyperthyroidism is prescribed methimazole. The nurse should instruct the client that the purpose of this medication is to:
- A. Decrease thyroid hormone production
- B. Increase thyroid hormone production
- C. Suppress the immune system
- D. Prevent thyroid storm
Correct answer: A
Rationale: The correct answer is A: Decrease thyroid hormone production. Methimazole works by inhibiting the synthesis of thyroid hormones, specifically by blocking the enzyme responsible for this process. By reducing the production of thyroid hormones, methimazole helps to normalize the elevated levels seen in hyperthyroidism. Choices B, C, and D are incorrect. Choice B, 'Increase thyroid hormone production,' is inaccurate as methimazole actually decreases thyroid hormone production. Choice C, 'Suppress the immune system,' is unrelated to the mechanism of action of methimazole. Choice D, 'Prevent thyroid storm,' is not the primary purpose of methimazole; while it may help prevent worsening of hyperthyroidism, its main action is to reduce thyroid hormone levels.
3. What clinical feature distinguishes a hypoglycemic reaction from a ketoacidosis reaction?
- A. Blurred vision.
- B. Diaphoresis.
- C. Nausea.
- D. Weakness.
Correct answer: B
Rationale: Diaphoresis is the correct answer because it is more characteristic of hypoglycemia. Hypoglycemia typically presents with symptoms such as diaphoresis (excessive sweating), palpitations, tremors, and anxiety. On the other hand, ketoacidosis is associated with symptoms such as fruity breath, deep and labored breathing (Kussmaul respirations), nausea, vomiting, and abdominal pain. Blurred vision can occur in both hypoglycemia and ketoacidosis due to metabolic disturbances affecting the eyes. Weakness is a nonspecific symptom that can be present in both conditions, making it less helpful in distinguishing between the two.
4. The nurse is caring for a client with diabetes insipidus. Which of the following laboratory findings should the nurse monitor?
- A. Serum sodium
- B. Serum potassium
- C. Serum calcium
- D. Serum magnesium
Correct answer: A
Rationale: In diabetes insipidus, there is excessive excretion of water leading to dehydration. Monitoring serum sodium levels is crucial because these clients often experience hypernatremia (elevated serum sodium levels) due to the loss of relatively more water than sodium, resulting in a sodium concentration imbalance. While monitoring serum potassium, calcium, and magnesium levels is also important in various conditions, they are not the primary focus in diabetes insipidus.
5. Acarbose (Precose), an alpha-glucosidase inhibitor, is prescribed for a female client with type 2 diabetes mellitus. During discharge planning, nurse Pauleen would be aware of the client's need for additional teaching when the client states:
- A. If I have hypoglycemia, I should eat some sugar, not dextrose.
- B. The drug makes my pancreas release more insulin.
- C. I should never take insulin while I'm taking this drug.
- D. It's best if I take the drug with the first bite of a meal.
Correct answer: B
Rationale: The correct answer is B. Acarbose (Precose) is an alpha-glucosidase inhibitor that works by slowing carbohydrate absorption in the intestine, not by stimulating insulin release. Therefore, the client would need additional teaching if they state that the drug makes their pancreas release more insulin (Choice B). Choices A, C, and D are incorrect. Choice A is incorrect because during hypoglycemia, it is recommended to consume glucose or dextrose to rapidly raise blood sugar levels. Choice C is incorrect because insulin therapy may still be needed in some cases, even when taking acarbose. Choice D is incorrect because acarbose should be taken at the start of a meal to help reduce postprandial blood glucose levels.
