A nurse is reinforcing teaching with a newly licensed nurse about monitoring morphine patient-controlled analgesia (PCA). Which of the following information should the nurse include?
"Using morphine PCA increases the client's risk of toxicity.”
"Diarrhea is an adverse effect of morphine PCA.”
"Check the client's pain level every 8 hours.”
"Instruct the client's visitors not to operate the PCA pump.”
The Correct Answer is D
Choice A rationale:
Using PCA does not necessarily increase the client’s risk of toxicity. PCA allows the client to self-administer preset doses of pain medication, which can lead to better pain control with less risk of overdose.
Choice B rationale:
Diarrhea is not a common adverse effect of morphine. Constipation, not diarrhea, is a common side effect due to slowed gastrointestinal motility.
Choice C rationale:
Checking the client’s pain level every 8 hours is not sufficient when using PCA. Pain levels should be assessed more frequently, ideally before and after each administration of the medication. This allows for timely adjustments to the medication regimen if needed.
Choice D rationale:
Instructing the client’s visitors not to operate the PCA pump is crucial. Only the patient should administer doses to prevent overdose.

Correct Answer is A
Explanation
Choice A rationale:
Renal excretion time slows for medication. As people age, kidney function gradually decreases, which slows the excretion of medications. This can lead to increased levels of the drug in the body, which can increase the risk of side effects.
Choice B rationale:
Hepatic enzymes do not process medications more rapidly in older adults. In fact, liver function also decreases with age, which can slow the metabolism of medications.
Choice C rationale:
Brain receptors do not become less sensitive to medications in older adults. The sensitivity of brain receptors to medications can vary widely and is not necessarily related to age.
Choice D rationale:
Gastric emptying rate does not increase with age. On the contrary, it often slows down, which can affect the absorption of some medications.
Correct Answer is B
Explanation
Choice A rationale:
Hydrochlorothiazide is a diuretic medication and does not interfere with the absorption of tetracycline.
Choice B rationale:
Antacids can interfere with the absorption of tetracycline, reducing its effectiveness. Therefore, they should be taken 3 hours before or after taking tetracycline.
Choice C rationale:
Lovastatin is a lipid-lowering medication and does not interfere with the absorption of tetracycline.
Choice D rationale:
Acetaminophen is an analgesic and does not interfere with the absorption of tetracycline.
