Question 1 of 5
A nurse is assessing a client who is taking phenelzine and reports eating aged cheese. Which of the following is a manifestation of an interaction between the medication and the food?
Correct Answer: A
Rationale: The correct answer is A: Hypertension. Phenelzine is a monoamine oxidase inhibitor (MAOI) that can interact with tyramine-rich foods like aged cheese, leading to a hypertensive crisis. Tyramine can displace norepinephrine, causing a sudden increase in blood pressure. Bradycardia (
B), somnolence (
C), and diarrhea (
D) are not typically associated with this interaction. It is important for the nurse to assess for signs of hypertension and educate the client to avoid tyramine-rich foods to prevent adverse effects.
Question 2 of 5
A nurse is assessing a client who has received oxycodone. The nurse notes that the client's respiratory rate is 8/min. The nurse should identify that which of the following is the pathophysiology for the client's respiratory rate?
Correct Answer: D
Rationale: The correct answer is D: Oxycodone causes central nervous system depression. Oxycodone is an opioid that acts on the central nervous system, specifically the brainstem, to depress respiratory drive. This leads to a decreased respiratory rate, as seen in the client with a rate of 8/min. The other options are incorrect because: A: Oxycodone does not inhibit prostaglandin synthesis. B: Oxycodone does not promote vasodilation of cranial arteries. C: Oxycodone does not block the sodium channel suspending nerve conduction. In summary, the client's decreased respiratory rate is due to the central nervous system depressant effect of oxycodone.
Question 3 of 5
A nurse is caring for a client who is mechanically ventilated and receiving propofol intravenously. Which of the following manifestations should the nurse identify as a complication of administration?
Correct Answer: B
Rationale: The correct answer is B: Sepsis. Propofol can suppress the immune response, increasing the risk of infection such as sepsis. Hypokalemia (
A) is not a common complication of propofol administration. Urinary retention (
C) is not directly related to propofol. Hypoglycemia (
D) is not a common complication of propofol use.
Therefore, sepsis is the most likely complication to be identified in a client receiving propofol.
Question 4 of 5
A nurse is taking a medication history from a client who has a new prescription for levothyroxine. The nurse should instruct the client to wait 4 hr after taking levothyroxine before taking which of the following supplements?
Correct Answer: D
Rationale: The correct answer is D: Calcium. Levothyroxine can bind to calcium, reducing its absorption. Instructing the client to wait 4 hours after taking levothyroxine before taking calcium ensures optimal absorption of both medications. Zinc (
A), Vitamin C (
B), and Ginkgo biloba (
C) do not have significant interactions with levothyroxine that would require specific timing. Waiting 4 hours before taking calcium is crucial to prevent any interference with levothyroxine absorption.
Question 5 of 5
A nurse is reviewing the medication administration record for a client who has cancer and is receiving morphine via a PCA pump. Which of the following prescriptions should the nurse clarify with the provider?
Correct Answer: B
Rationale: The correct answer is B: Nalbuphine. The nurse should clarify this prescription with the provider because nalbuphine is a opioid analgesic like morphine, and using both together can increase the risk of respiratory depression. Ondansetron (
A) is an antiemetic commonly used with opioids. Insulin glargine (
C) and acetaminophen (
D) do not have significant interactions with morphine.
