A client is started on levothyroxine for the treatment of hypothyroidism. During client teaching, the nurse indicates that the dosage may be increased how often until symptoms are relieved?
Weekly
Monthly
Every 3 to 5 days
Every 4 to 6 weeks
The Correct Answer is D
A. Weekly – This frequency is too frequent for dosage adjustments of levothyroxine. Adjustments are generally made less frequently to allow for the medication to reach therapeutic levels.
B. Monthly – While some adjustments may be made on a monthly basis, this is not the typical recommendation.
C. Every 3 to 5 days – This is also too frequent for dosage adjustments as it may not allow enough time to assess the effects of the current dose.
D. Every 4 to 6 weeks – This is the correct recommendation for adjusting levothyroxine dosages. After starting therapy or adjusting the dose, it is advised to wait 4 to 6 weeks before evaluating thyroid function tests and making any further adjustments to the dosage, as it takes time for the medication to take effect.

Explanation
Hydrocortisone is a synthetic form of the hormone cortisol, which is produced by the adrenal glands. Addison's disease is a condition in which the adrenal glands do not produce enough cortisol and other hormones. Treatment with hydrocortisone is a lifelong therapy that replaces the missing hormones.
One of the potential adverse effects of long-term treatment with hydrocortisone is the development of sodium depletion or hyponatremia. This occurs because hydrocortisone can increase the excretion of sodium in the urine, leading to low levels of sodium in the blood.
To mitigate this potential adverse effect, the nurse should encourage the client to increase their intake of sodium. This can be done through dietary sources such as adding more salt to their food or drinking sports drinks that contain electrolytes. The client should also be monitored closely for signs of sodium depletion, such as weakness, fatigue, and confusion.
It is also important to note that long-term treatment with hydrocortisone can increase the risk of other adverse effects, such as osteoporosis, hyperglycemia, and infection. The nurse should educate the client on these potential adverse effects and encourage them to follow their healthcare provider's instructions for monitoring and management.
