You are caring for a client with hypothyroidism that is taking levothyroxine (Synthroid). The client reports diarrhea, weight loss, palpitations, and heat intolerance. You suspect which of the following adverse effects of this drug?
Hypothyroidism
Thyrotoxicosis
Addison's Disease
Cushing's Disease
The Correct Answer is B
A. Hypothyroidism: This is incorrect. The client is taking levothyroxine (Synthroid) to treat hypothyroidism, and the symptoms described (diarrhea, weight loss, palpitations, heat intolerance) are more likely associated with excess thyroid hormone, not a lack of it.
B. Thyrotoxicosis: This is correct. The symptoms the client is experiencing—diarrhea, weight loss, palpitations, and heat intolerance—are classic signs of thyrotoxicosis, which occurs when there is an excess of thyroid hormone, possibly due to overtreatment with levothyroxine. These symptoms indicate that the thyroid hormone dose might need adjustment.
C. Addison's Disease: This is incorrect. Addison's disease is characterized by insufficient production of adrenal hormones and would typically manifest with symptoms such as fatigue, hypotension, and hyperpigmentation, not diarrhea or heat intolerance.
D. Cushing's Disease: This is incorrect. Cushing's disease is caused by excess cortisol and would typically result in symptoms such as weight gain, high blood pressure, and a round "moon" face, rather than the symptoms described in the question.

Explanation
A. Dimenhydrinate is an antihistamine commonly used to treat motion sickness by reducing the stimulation of the vestibular system.
B. Metoclopramide is not used for motion sickness. Its primary use is for nausea and vomiting caused by conditions such as gastroparesis or chemotherapy, as it works by enhancing gastrointestinal motility.
C. Scopolamine is specifically indicated for motion sickness. It acts as an anticholinergic to reduce the effects of motion on the vestibular system.
D. Ondansetron is not used for motion sickness. It is a serotonin antagonist primarily used to treat nausea and vomiting associated with chemotherapy, radiation, or postoperative recovery.
Correct Answer is ["A","D"]
Explanation
A. Long-term use of omeprazole is associated with an increased risk of osteoporosis and fractures due to decreased calcium absorption caused by reduced stomach acid. This complication is significant in older adults, particularly with prolonged therapy.
B. Torsades de Pointes is not a common complication of omeprazole. QT prolongation is more often linked to medications like ondansetron or antiarrhythmics.
C. Nausea is not a typical complication of omeprazole; rather, it is a symptom the drug may help alleviate as part of managing gastrointestinal conditions.
D. Rebound acid hypersecretion can occur after discontinuation of omeprazole. The body may produce an excessive amount of acid to compensate for the previous suppression, leading to worsening symptoms if the medication is abruptly stopped.
