Question 1

Which of the following best describes the mechanism of action of opioid analgesics in pain management?

Accepted Answer

They inhibit the transmission and perception of pain signals by binding to opioid receptors in the central nervous system.

Question 2

Accepted Answer

Opioid agonists

Question 3

A 65-year-old patient with chronic kidney disease is prescribed morphine for postoperative pain. Which of the following is the most important consideration?

Accepted Answer

Morphine should be avoided or used with caution due to risk of metabolite accumulation and toxicity.

Question 4

Which of the following statements about opioid agonists/antagonists, such as butorphanol, is correct?

Accepted Answer

They have a ceiling effect on respiratory depression, making them safer in overdose than pure agonists.

Question 5

A patient is brought to the emergency department with respiratory depression after an opioid overdose. Which drug should be administered to reverse these effects?

Accepted Answer

Naloxone

Question 6

Which of the following is NOT a contraindication for opioid use?

Accepted Answer

Mild, well-controlled hypertension

Question 7

A patient with a history of opioid abuse is given naloxone for suspected overdose. What is a possible adverse effect of naloxone administration in this scenario?

Accepted Answer

Precipitation of acute withdrawal symptoms, including tachycardia and hypertension

Question 8

Which of the following best explains why opioid analgesics are classified as Schedule II drugs?

Accepted Answer

They have accepted medical use but a high potential for abuse and dependence.

Question 9

A patient is receiving patient-controlled analgesia (PCA) with morphine. Which of the following best describes the pharmacokinetics of morphine?

Accepted Answer

It is extensively metabolized in the liver and excreted in the urine.

Question 10

Which of the following is a major effect of opioid agonists on the gastrointestinal (GI) system?

Accepted Answer

Decreased GI motility leading to constipation

Question 11

A 30-year-old woman in labor is given an opioid agonist/antagonist for pain management. Which of the following is a key consideration for this therapy?

Accepted Answer

It is appropriate if there are no signs of fetal respiratory distress.

Question 12

Which of the following best describes the role of endogenous opioid peptides in pain modulation?

Accepted Answer

They interact with opioid receptors to inhibit the perception and transmission of pain signals.

Question 13

A patient with a history of head injury is prescribed an opioid for pain. What is the primary concern with opioid use in this patient?

Accepted Answer

Opioids may increase intracranial pressure, worsening the patient's condition.

Question 14

Which of the following is the gold standard for pain assessment in clinical practice?

Accepted Answer

Self-reporting by the patient

Question 15

A patient is prescribed butorphanol for moderate pain. Which of the following adverse effects should the nurse monitor for?

Accepted Answer

Headache, dizziness, and hallucinations

Question 16

Which of the following best describes the pathophysiology of pain sensation?

Accepted Answer

Pain signals travel from nociceptors in peripheral tissue to the spinal cord, then to the brain for perception.

Question 17

A patient is taking an opioid agonist for chronic pain. After several weeks, the patient reports that the medication is less effective. What is the most likely explanation?

Accepted Answer

The patient has developed tolerance to the opioid.

Question 18

Which of the following is a key difference between opioid agonists and opioid antagonists?

Accepted Answer

Opioid agonists activate opioid receptors to produce analgesia, while antagonists block these receptors to reverse opioid effects.

Question 19

A patient with severe abdominal cramping and diarrhea is prescribed an opioid. Which effect of opioids is most beneficial in this scenario?

Accepted Answer

Decreased GI motility

Question 20

Which of the following is a correct statement regarding opioid use in older adults?
