The nurse is assessing a patient for contraindications to drug therapy with acetaminophen.
Which patient should not receive acetaminophen?
A patient with a history of peptic ulcer disease
A patient with a history of liver disease
A patient who is complaining of a mild headache
A patient with a fever of 101°F (38.3°C)
The Correct Answer is B
A. Acetaminophen is generally considered safe for patients with a history of peptic ulcer disease.
It does not irritate the gastrointestinal mucosa like nonsteroidal anti-inflammatory drugs (NSAIDs).
B. Patients with a history of liver disease should not receive acetaminophen or should use it with caution and under close supervision, as acetaminophen is metabolized in the liver. Liver
impairment can lead to decreased metabolism of acetaminophen, potentially resulting in drug accumulation and hepatotoxicity.
C. Acetaminophen is commonly used to relieve mild to moderate headaches. However, the appropriateness of acetaminophen use in this scenario depends on the patient's overall health status and any contraindications specific to the individual.
D. Acetaminophen is often used to reduce fever. A fever of 101°F (38.3°C) alone does not necessarily contraindicate acetaminophen use, but caution should be exercised in patients with liver disease.

Correct Answer is ["A","C","D","E"]
Explanation
A. Monitor the patient's respiratory rate: It's essential to monitor the patient for any adverse effects of morphine administration, particularly respiratory depression.
B. Ensure naloxone is readily available: While naloxone is an antidote for opioid overdose, administering it would depend on the patient's response and any signs of opioid toxicity, which may not be evident at this time.
C. Report the error to the facility through the proper paperwork: Reporting the medication error is crucial for documentation, investigation, and implementation of corrective actions.
D. Inform the patient's health care provider: The healthcare provider should be notified of the medication error to ensure appropriate follow-up and monitoring of the patient.
E. Document the dose of morphine given by the MedSurg nurse: Documenting the medication administration accurately is essential for the patient's medical record and continuity of care.
Correct Answer is ["A","D","E"]
Explanation
A. Oral contraceptives: Phenobarbital can decrease the effectiveness of oral contraceptives, increasing the risk of contraceptive failure and unintended pregnancy.
B. Antihistamines: While phenobarbital can induce hepatic enzymes, leading to increased
metabolism of some antihistamines, this interaction is less clinically significant compared to the interactions with oral contraceptives, opioids, and diuretics.
C. Warfarin: Phenobarbital can induce the metabolism of warfarin, potentially reducing its anticoagulant effects and necessitating closer monitoring of international normalized ratio (INR) levels.
D. Opioids: Phenobarbital can increase the metabolism of opioids, leading to reduced analgesic effects and potentially causing inadequate pain control.
E. Diuretics: Phenobarbital can accelerate the metabolism of diuretics, potentially reducing their efficacy and necessitating adjustments in dosage or monitoring of electrolyte levels.
