What is the lowest fasting plasma glucose level suggestive of a diagnosis of DM?
- A. 90 mg/dl.
- B. 115 mg/dl.
- C. 126 mg/dl.
- D. 180 mg/dl.
Correct Answer: C
Rationale: A fasting plasma glucose level of 126 mg/dl or higher is diagnostic of diabetes mellitus. Choice A (90 mg/dl) is too low to indicate diabetes. Choice B (115 mg/dl) is also below the diagnostic threshold for diabetes. Choice D (180 mg/dl) is above the diagnostic threshold and would indicate uncontrolled diabetes, not the lowest level suggestive of a diagnosis.

When implementing a new policy on the unit, what process should a nurse manager follow?
- A. The nurse manager should involve staff members in the decision-making process, gather input, and communicate the reasons for the policy change to ensure buy-in from the team.
- B. The nurse manager should implement the policy change immediately and monitor staff compliance to ensure that the new policy is being followed.
- C. The nurse manager should delegate the implementation of the policy change to a staff member and provide support as needed to ensure that the change is successful.
- D. The nurse manager should communicate the policy change to staff members, provide training as needed, and monitor the implementation process to ensure that the change is effective.
Correct Answer: A
Rationale: When introducing a new policy on the unit, it is essential for the nurse manager to involve staff members in the decision-making process. This approach helps in gathering input and insights from the team, fostering a sense of ownership and commitment. By communicating the reasons behind the policy change, the nurse manager ensures transparency and promotes understanding among the staff, leading to buy-in and acceptance of the new policy. Choice B is incorrect because implementing a policy change without involving staff and explaining the rationale may lead to resistance or lack of understanding. Choice C is not ideal as delegation without active involvement and communication with the team may result in misunderstandings or incomplete implementation. Choice D lacks the crucial step of involving staff in the decision-making process, which is important for successful policy implementation and team engagement.
A client with Graves' disease is prescribed propranolol. The nurse understands that the purpose of this medication is to:
- A. Treat the underlying cause of the disease
- B. Reduce thyroid hormone production
- C. Alleviate symptoms such as tachycardia and tremors
- D. Increase energy levels
Correct Answer: C
Rationale: The correct answer is C: Alleviate symptoms such as tachycardia and tremors. Propranolol is a beta-blocker that helps manage symptoms like tachycardia (fast heart rate) and tremors in patients with Graves' disease. Choice A is incorrect because propranolol does not address the underlying cause of Graves' disease, which is autoimmune in nature. Choice B is incorrect because propranolol does not directly reduce thyroid hormone production; it mainly targets the symptoms. Choice D is incorrect because while propranolol may help with symptoms like tachycardia, it is not intended to increase energy levels.
When caring for a female client with a history of hypoglycemia, Nurse Ruby should avoid administering a drug that may potentiate hypoglycemia. Which drug fits this description?
- A. Sulfisoxazole (Gantrisin)
- B. Mexiletine (Mexitil)
- C. Prednisone (Orasone)
- D. Lithium carbonate (Lithobid)
Correct Answer: A
Rationale: The correct answer is A, Sulfisoxazole (Gantrisin). Sulfisoxazole is known to potentiate hypoglycemia, making it unsafe for clients with a history of hypoglycemia. Choice B, Mexiletine, is a medication used to treat certain heart rhythm problems and is not associated with hypoglycemia. Choice C, Prednisone, is a corticosteroid and does not potentiate hypoglycemia. Choice D, Lithium carbonate, is commonly used to treat bipolar disorder and does not typically potentiate hypoglycemia. Therefore, the drug that Nurse Ruby should avoid in this case is Sulfisoxazole (Gantrisin) to prevent worsening the client's hypoglycemic condition.
A client with hypothyroidism is receiving levothyroxine therapy. The healthcare provider should monitor for which of the following signs of medication overdose?
- A. Bradycardia
- B. Weight gain
- C. Tachycardia
- D. Cold intolerance
Correct Answer: C
Rationale: The correct answer is C: Tachycardia. Tachycardia is a sign of levothyroxine overdose, indicating that the dose may need to be adjusted. Bradycardia (Choice A) is a sign of hypothyroidism, not an overdose of levothyroxine. Weight gain (Choice B) and cold intolerance (Choice D) are also symptoms of hypothyroidism, not medication overdose.
A client with hyperthyroidism is prescribed radioactive iodine therapy. The nurse should monitor for which of the following potential side effects?
- A. Hypothyroidism
- B. Hyperthyroidism
- C. Hypercalcemia
- D. Hyperglycemia
Correct Answer: A
Rationale: When a client with hyperthyroidism undergoes radioactive iodine therapy, the treatment aims to reduce thyroid hormone production by destroying thyroid tissue. As a result, there is a high likelihood of developing hypothyroidism as a side effect. Monitoring for hypothyroidism is crucial post-treatment. Choices B, C, and D are incorrect because the therapeutic goal is to address hyperthyroidism by inducing hypothyroidism through the treatment.
