The healthcare provider prescribes propylthiouracil (PTU) and Lugol's solution, a strong iodine solution, for a client with hyperthyroidism. How should the nurse schedule the administration of these medications?

Offer both drugs together with a meal.

Administer iodine one hour before PTU.

Schedule both medications at bedtime.

Give parental dose once every 24 hours.

Answer and Explanation

The Correct Answer is B

A. Offer both drugs together with a meal:
Propylthiouracil (PTU) and Lugol's solution are typically not administered together with a meal. Lugol's solution, a strong iodine solution, is generally taken separately from PTU to avoid potential interactions and ensure optimal absorption of each medication.

B. Administer iodine one hour before PTU:
Lugol’s solution (iodine) is usually given before PTU because iodine can decrease the vascularity of the thyroid gland and make the thyroid gland less active, which helps PTU work more effectively. This timing helps optimize the therapeutic effects of both medications.

C. Schedule both medications at bedtime:
The timing of administration for PTU and Lugol’s solution is based on their specific interactions and pharmacokinetics rather than convenience. Scheduling them at bedtime does not align with the recommended practice for their optimal effectiveness.

D. Give parental dose once every 24 hours:
Both PTU and Lugol’s solution are not administered as a single dose every 24 hours. PTU is typically given multiple times per day to maintain effective blood levels, and Lugol’s solution is usually given as directed by the healthcare provider, often several times a day but not necessarily in a single 24-hour dose.

Correct Answer is ["200"]

Explanation

Calculations:

Total volume of the IV bag = 200 mL

Infusion time = 1 hour

To calculate the infusion rate in mL/hr, we use the formula:

Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hours)

Infusion rate (mL/hr) = 200 mL / 1 hour = 200 mL/hr

Therefore, the nurse should program the infusion pump to deliver 200 mL/hr.

A. Worsening headache. B. Low urine specific gravity. C. Polyuria. D. Polydipsia.

Correct Answer is A

Explanation

A. Worsening headache:
Vasopressin is used to manage diabetes insipidus by reducing excessive urine output and increasing water reabsorption. A worsening headache could indicate an adverse reaction or side effect such as water intoxication or an increase in intracranial pressure, which requires immediate attention from the healthcare provider.

B. Low urine specific gravity:
Vasopressin should increase urine specific gravity by concentrating the urine. A low urine specific gravity would indicate that the medication is not effectively concentrating the urine, but it is not an immediate or severe side effect needing urgent reporting.

C. Polyuria:
Polyuria (excessive urine output) is a characteristic of diabetes insipidus, and vasopressin is intended to reduce this symptom. If polyuria persists despite treatment, it suggests that the medication is not working as intended but does not indicate a severe side effect.

D. Polydipsia:
Polydipsia (excessive thirst) can occur in diabetes insipidus and may continue despite treatment with vasopressin. While it indicates ongoing symptoms, it is not a severe side effect of the medication that would require urgent reporting to the healthcare provider.
