Morphine and Synthetic Opioids Practice Quiz (13 questions)

Question 1

1. Which description best characterizes opioid analgesia?

Mild, constant relief that does not vary with dose

Intense, constant, dose-dependent relief across all types of pain

Dose-dependent sedation without pain relief

Intense relief limited to particular types of pain

Explanation

Opioids produce intense, constant, dose-dependent analgesia and act on all types of pain. A fixed effect ignores dose dependence, pain-type restriction contradicts the broad action, and sedation is a separate effect.

Answer

Intense, constant, dose-dependent relief across all types of pain

Question 2

2. A patient receiving an opioid develops pinpoint pupils, nausea, and vomiting. How are these effects classified?

Inhibitory effects

Hypnotic effects

Excitatory effects

Respiratory effects

Explanation

Miosis, nausea, and vomiting are listed as excitatory opioid effects. Inhibitory effects include analgesia, respiratory depression, and somnolence; respiratory depression and hypnosis do not classify the described signs.

Answer

Excitatory effects

Question 3

3. After receiving an opioid, a patient responds less effectively to low oxygen and elevated carbon dioxide, while breathing more slowly with increased tidal volume. Which opioid effect best explains this pattern?

Depression of respiratory responses and rate regulation

Stimulation of respiratory responses and rate regulation

Preservation of respiratory responses with a slower rate

Depression of tidal volume with a faster respiratory rate

Explanation

Opioids depress responses to hypoxia and hypercapnia and impair regulation of respiratory rate; the described pattern also includes increased tidal volume and decreased rate. Reduced tidal volume and faster breathing reverse the noted changes, while preserved responses contradict the mechanism.

Answer

Depression of respiratory responses and rate regulation

Question 4

4. A clinician is administering morphine using the described bolus regimen. Which dose and interval should be used?

A titrated 2 mg bolus every 15 minutes

A titrated 10 mg bolus every 5 minutes

A titrated 2 mg bolus every 5 minutes

A titrated 5 mg bolus every 2 minutes

Explanation

The described morphine regimen is a titrated 2 mg bolus every 5 minutes. The 10 mg value is the amount in an ampoule, while the other choices alter the stated dose or interval.

Answer

A titrated 2 mg bolus every 5 minutes

Question 5

5. A patient receives intravenous morphine at noon. Which timeline best describes its onset, peak effect, and duration of action?

Begins at 12:15, peaks around 12:20–12:30, and acts for 2–3 hours

Begins at 12:20–12:30, peaks at 12:15, and acts for 2–3 hours

Begins at 12:15, peaks after 2–3 hours, and acts for 20–30 minutes

Begins at 12:15, peaks around 12:20–12:30, and acts for up to 4 hours

Explanation

Intravenous morphine begins acting after 15 minutes, reaches maximum effect after 20–30 minutes, and acts for 2–3 hours. The up-to-4-hour figure refers to residual effect, not the usual duration; the other timelines interchange onset, peak, or duration.

Answer

Begins at 12:15, peaks around 12:20–12:30, and acts for 2–3 hours

Question 6

6. A clinician compares the listed potency of alfentanil, fentanyl, and remifentanil with morphine. Which ordering, from lowest to highest potency, is supported by the listed figures?

Fentanyl, alfentanil, remifentanil

Alfentanil, remifentanil, fentanyl

Alfentanil, fentanyl, remifentanil

Alfentanil, fentanyl, sufentanil

Explanation

The listed figures are 30-fold for alfentanil, 50–100-fold for fentanyl, and 300-fold for remifentanil, giving that ascending order. Reversing alfentanil and fentanyl misreads their figures; placing fentanyl above remifentanil misreads the 300-fold figure; sufentanil has no listed potency figure.

Answer

Alfentanil, fentanyl, remifentanil

Question 7

7. A patient is to receive an induction dose of remifentanil over one minute. Which dose range matches the listed regimen?

5–10 μg/kg

3–5 μg/kg

0.5–1 μg/kg

0.2–0.5 μg/kg

Explanation

The listed remifentanil induction dose is 0.5–1 μg/kg over one minute. The 5–10, 3–5, and 0.2–0.5 μg/kg ranges correspond to alfentanil, fentanyl, and sufentanil, respectively.

Answer

0.5–1 μg/kg

Question 8

8. After administration of one of the listed synthetic opioids, a clinician expects its listed duration of action to be under 10 minutes. Which drug fits that expectation?

Alfentanil

Sufentanil

Remifentanil

Fentanyl

Explanation

Remifentanil is listed as lasting under 10 minutes. Alfentanil is listed at 7–10 minutes, fentanyl at 20–30 minutes, and sufentanil at 30 minutes; the first is a distinct listed duration, while the others do not match the stated range.

Answer

Remifentanil

Question 9

9. A patient with asthma and acute alcohol intoxication is being considered for opioid treatment. How do these conditions relate to the listed contraindications?

Neither is listed as a contraindication

Asthma is listed, but acute alcohol intoxication is not

Acute alcohol intoxication is listed, but asthma is not

Both are listed contraindications

Explanation

Asthma and acute alcohol intoxication are both included in the listed contraindications. Treating asthma as monitoring alone or alcohol intoxication as merely a post-dose adverse effect misclassifies listed contraindications; the antidote is a separate issue.

Answer

Both are listed contraindications

Question 10

10. During opioid treatment, a clinician is establishing a monitoring plan. Which set of observations matches the listed monitoring domains?

Respiratory rate, sedation, pain, and adverse effects

Blood pressure, sedation, renal function, and adverse effects

Respiratory rate, drug potency, blood pressure, and renal function

Respiratory rate, renal function, pain, and drug potency

Explanation

The listed monitoring domains are respiratory rate, central nervous system depression and sedation, analgesia and pain level, and adverse effects. Blood pressure, renal function, and drug potency do not replace those stated domains.

Answer

Respiratory rate, sedation, pain, and adverse effects

Question 11

11. Which medication is listed as the antidote for opioid effects?

Midazolam

Paracetamol

Morphine

Naloxone (Narcan)

Explanation

Naloxone, marketed as Narcan, is listed as the opioid antidote. Morphine is an opioid analgesic, while midazolam is a sedative and paracetamol is a non-opioid pain reliever.

Answer

Naloxone (Narcan)

Question 12

12. A patient receiving an opioid develops difficulty urinating. Which additional finding is also a recognized opioid adverse effect?

Reduced biliary tract pressure

Constipation

Mydriasis

Diarrhea

Explanation

Opioids can slow gastrointestinal activity, causing constipation, and can also cause urinary retention. Diarrhea, reduced biliary pressure, and pupil dilation do not match the listed opioid effects.

Answer

Constipation

Question 13

13. After a patient stops opioid treatment, withdrawal symptoms appear; during treatment, progressively larger doses had been needed for the same effect. Which terms describe these two observations, respectively?

Tolerance and physical dependence

Psychological dependence and tolerance

Physical dependence and psychological dependence

Physical dependence and tolerance

Explanation

Withdrawal after treatment stops indicates physical dependence, while needing larger doses for the same effect indicates tolerance. Reversing those terms confuses the two concepts; psychological dependence is not defined by either observation here.

Answer

Physical dependence and tolerance
