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 ["B","D"]
Explanation
A. Restlessness is not a common side effect of cimetidine. Neurological side effects typically involve sedation or confusion rather than hyperactivity.
B. Lethargy is a potential adverse effect of cimetidine, especially in older adults or those with renal dysfunction, due to the drug’s impact on the central nervous system.
C. Increased libido is not associated with cimetidine. In fact, it may cause decreased libido and sexual dysfunction in some cases.
D. Confusion is a known complication of cimetidine, particularly in elderly clients with impaired renal function, as the drug can accumulate in the body and affect the brain.
Correct Answer is A
Explanation
A. Hyperglycemia: While metformin is used to manage blood glucose levels in clients with diabetes, its interaction with contrast dye does not directly lead to hyperglycemia. However, the risk for kidney injury, which can affect glucose regulation, is a concern.
B. Acute renal failure: This is correct. The combination of metformin and iodine-containing contrast dye increases the risk of acute renal failure, also known as contrast-induced nephropathy (CIN). This occurs because contrast agents can cause kidney damage, and metformin is excreted by the kidneys. If renal function is impaired, the buildup of metformin can lead to lactic acidosis.
C. Acute pancreatitis: While acute pancreatitis is a possible side effect of metformin in some individuals, the primary concern with iodine-containing contrast dye is renal failure, not pancreatitis.
D. Acute liver failure: Metformin is primarily metabolized by the kidneys, not the liver, and does not commonly cause liver failure. Renal failure is the more pressing concern with the use of contrast dye in clients taking metformin.
