A nurse is reviewing a client’s medical history before administering a new prescription for atropine. Which of the following client conditions is contraindicated?
Bronchospasms
Diarrhea
Glaucoma
Diverticulitis
The Correct Answer is C
A. Bronchospasms are not a contraindication for atropine. In fact, atropine can be used to treat bronchospasms in certain situations because it helps to relax the airways.
B. Diarrhea is not a contraindication for atropine. Atropine can actually be used to treat diarrhea by reducing gastrointestinal motility.
C. Glaucoma is a contraindication for atropine. Atropine can increase intraocular pressure, which can worsen glaucoma and potentially lead to vision loss.
D. Diverticulitis is not a contraindication for atropine. Atropine does not have a direct effect on diverticulitis.

Correct Answer is C
Explanation
A. “Call 911 if pain persists 30 minutes after taking one tablet” is incorrect. The client should call 911 if chest pain persists after taking three doses of nitroglycerin at 5-minute intervals, not 30 minutes.
B. “Take a tablet every 10 minutes until the pain subsides” is incorrect. The correct instruction is to take one tablet every 5 minutes, up to three tablets, and seek emergency help if the pain does not subside.
C. “Place the tablet under the tongue until dissolved” is correct. Sublingual nitroglycerin should be placed under the tongue to dissolve, allowing for rapid absorption and relief of angina.
D. “Store the tablets in a refrigerator in a plastic container” is incorrect. Nitroglycerin tablets should be stored at room temperature in their original glass container to maintain potency.
Correct Answer is D
Explanation
A. Oxycodone promotes vasodilation of cranial arteries. This is not the primary mechanism by which oxycodone affects respiratory rate. Vasodilation of cranial arteries is not directly related to respiratory depression.
B. Oxycodone blocks the sodium channel suspending nerve conduction. This is not the primary mechanism of action for oxycodone. Oxycodone primarily acts on opioid receptors rather than sodium channels.
C. Oxycodone inhibits prostaglandin synthesis. This is not the primary mechanism of action for oxycodone. Inhibition of prostaglandin synthesis is more characteristic of nonsteroidal anti-inflammatory drugs (NSAIDs).
D. Oxycodone causes central nervous system depression. This is the correct explanation. Oxycodone, like other opioids, depresses the central nervous system, which can lead to respiratory depression by reducing the brainstem’s responsiveness to carbon dioxide levels in the blood.
