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 ["A","C"]
Explanation
A. "I should apply this patch behind my ear.": This is correct because the scopolamine patch is designed to be applied behind the ear, where it can effectively deliver medication through the skin.
B. "This patch should be replaced every 7 days.": This is incorrect because the scopolamine patch should be replaced every 72 hours (3 days), not every 7 days.
C. "I should not use a second patch if the initial patch is ineffective.": This is correct because using more than one patch at a time can lead to an overdose of the medication, which can cause serious side effects.
D. "Before putting on my patch, I should wipe the area with an alcohol swab.": This is incorrect because using an alcohol swab can irritate the skin and affect the absorption of the medication. The area should be clean and dry, but not cleaned with alcohol.
Correct Answer is A
Explanation
A. Prolonged QT interval – This is correct. Ondansetron can cause prolongation of the QT interval, increasing the risk of arrhythmias, including torsades de pointes. This is a serious complication that requires monitoring, particularly in clients with cardiac risks.
B. Extrapyramidal symptoms – This is incorrect. Ondansetron does not typically cause extrapyramidal symptoms, which are more associated with dopamine antagonists like metoclopramide or prochlorperazine.
C. Nausea – This is incorrect. Ondansetron is specifically used to treat nausea and vomiting, not to cause them. If nausea persists, it may indicate treatment failure or another underlying issue.
D. Vomiting – This is incorrect. Ondansetron is an antiemetic and works to prevent vomiting. Vomiting would not be a complication of this medication under proper use.
