You are caring for a client with hyperthyroidism that is taking propylthiouracil (PTU). The client reports that she misunderstood the instructions and took more doses than her prescribed dosage. The client also reported drowsiness, weight gain, edema, and cold intolerance. You suspect which of the following adverse effects of this drug?
Hypothyroidism
Thyrotoxicosis
Cushing's Syndrome
Addison's Disease
The Correct Answer is A
A. "I will take both aluminum hydroxide (Amphojel) and cimetidine (Tagamet HB) at the same time." – This is correct. Taking aluminum hydroxide and cimetidine simultaneously reduces the effectiveness of cimetidine by impairing its absorption. This statement indicates a need for further teaching.
B. "I will take aluminum hydroxide (Amphojel) 1 hour before taking cimetidine (Tagamet HB)." – This is incorrect. Taking aluminum hydroxide 1 hour before cimetidine allows enough time for the antacid's effects on stomach acidity to stabilize, reducing interference.
C. "I can take aluminum hydroxide (Amphojel) 2 hours before taking cimetidine (Tagamet HB)." – This is incorrect. Taking the antacid 2 hours before cimetidine provides sufficient time for proper absorption of the medication.
D. None of the above – This is incorrect because statement A reflects improper administration.

Correct Answer is D
Explanation
A. Ondansetron agonizes serotonin receptors on afferent vagal neurons. – This is incorrect. Ondansetron works by blocking, not activating, serotonin (5-HT3) receptors in areas involved in nausea and vomiting.
B. Ondansetron agonizes serotonin receptors in the medulla oblongata. – This is incorrect. Ondansetron does not act as an agonist at serotonin receptors in the medulla oblongata; instead, it antagonizes receptors to reduce nausea.
C. Ondansetron agonizes dopaminergic receptors in the vestibular apparatus. – This is incorrect. Ondansetron does not affect dopaminergic receptors or the vestibular apparatus. Medications like promethazine address dopaminergic pathways.
D. Ondansetron blocks serotonin receptors in the chemoreceptor trigger zone. – This is correct. Ondansetron acts as a 5-HT3 receptor antagonist, blocking serotonin receptors in the chemoreceptor trigger zone and vagal nerve terminals, effectively preventing nausea and vomiting.
