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?

Schedule both medications at bedtime.

Administer iodine one hour before PTU.

Give parental dose once every 24 hours.

Offer both drugs together with a meal.

Answer and Explanation

The Correct Answer is B

A) Schedule both medications at bedtime:
Administering both medications at bedtime may not be the most appropriate schedule. PTU is typically administered multiple times a day to maintain consistent therapeutic levels in the bloodstream. Additionally, administering Lugol’s solution at bedtime may not provide sufficient time for the iodine to take effect before the PTU.

B) Administer iodine one hour before PTU:
This option is correct. Lugol’s solution, a strong iodine solution, is often given before antithyroid medications such as PTU or methimazole to temporarily block thyroid hormone production. Administering iodine about one hour before PTU allows the iodine to be taken up by the thyroid gland, effectively reducing thyroid hormone synthesis before the PTU starts to inhibit the conversion of T4 to T3.

C) Give parental dose once every 24 hours:
This option does not address the timing of administration between PTU and Lugol’s solution. While it may be correct for the dosing frequency of PTU, it does not specify when to administer Lugol’s solution in relation to PTU.

D) Offer both drugs together with a meal:
Administering both drugs together with a meal may not be appropriate, especially considering that Lugol’s solution needs to be absorbed into the bloodstream to exert its effect on the thyroid gland. Administering Lugol’s solution and PTU together may not allow adequate time for the iodine to take effect before the PTU starts to inhibit thyroid hormone production.

Correct Answer is A

Explanation

A) A dimly lit room:
Mydriatic medications cause pupil dilation by stimulating the dilator muscle of the iris. In bright light, dilated pupils can lead to photophobia (sensitivity to light) and discomfort for the client. Therefore, placing the client in a dimly lit room helps to minimize the discomfort associated with increased sensitivity to light. This environment also supports visual acuity and reduces the risk of visual disturbances that can occur with bright light.

B) A warm room temperature:
While maintaining a comfortable room temperature is important for overall client comfort, it is not specifically related to the administration of mydriatic medications. The choice of room temperature may vary based on the client’s preferences and individual comfort needs but is not directly influenced by the use of mydriatic medications.

C) Cool, humidified air:
Cool, humidified air may be beneficial for certain respiratory conditions or for promoting comfort in some clients. However, it is not directly relevant to the administration of mydriatic medications. The choice of room temperature and humidity level should prioritize the client’s overall comfort and specific health needs but does not specifically relate to the effects of mydriatic drugs.

D) A quiet, restful environment:
While providing a quiet, restful environment is important for promoting relaxation and comfort, it is not specifically related to the administration of mydriatic medications. Clients receiving mydriatic drugs may benefit from restful surroundings to minimize stress or anxiety, but this choice does not address the potential visual discomfort associated with pupil dilation induced by mydriatic drugs.

A. Request a prescription to change the route of administration and use the available heparin. B. Calculate and administer the equivalent dose of the available low molecular weight heparin. C. Advise the pharmacy of the need to deliver a vial of heparin to the nursing unit immediately. D. Dilute the available heparin in 250 mL of normal saline solution prior to IV administration.

Correct Answer is C

Explanation

A) Request a prescription to change the route of administration and use the available heparin:
Changing the route of administration without a prescription is not within the nurse's scope of practice and could lead to medication errors or adverse effects. It's essential to follow the prescribed route of administration to ensure patient safety.

B) Calculate and administer the equivalent dose of the available low molecular weight heparin:
Low molecular weight heparin (LMWH) has different dosing and potency compared to unfractionated heparin. Calculating an equivalent dose without a specific conversion ratio could result in under- or overdosing, leading to ineffective anticoagulation or increased risk of bleeding.

C) Advise the pharmacy of the need to deliver a vial of heparin to the nursing unit immediately:
This is the correct action. Since the prescription specifies unfractionated heparin administered intravenously, the nurse should notify the pharmacy to provide the correct medication promptly. Using a different form of heparin could lead to dosing errors or ineffective treatment.

D) Dilute the available heparin in 250 mL of normal saline solution prior to IV administration:
This action is not appropriate because it assumes that the available heparin is suitable for intravenous administration, which may not be the case. Dilution may also alter the concentration and potency of the medication, leading to inaccurate dosing and potential adverse effects.
