MULTIPLE CHOICE
1. A patient is prescribed morphine sulfate for postoperative
pain. The nurse understands that morphine acts on which
receptors to produce analgesia?
a. Alpha-adrenergic receptors
b. Dopamine receptors
c. Mu (μ) receptors
d. Serotonin receptors
Correct Solution: c. Mu (μ) receptors
Rationale: Morphine is an opioid agonist that primarily binds to
mu (μ) receptors in the central nervous system. This binding
inhibits the transmission of pain signals, producing analgesia,
sedation, and euphoria. Alpha-adrenergic, dopamine, and
serotonin receptors are involved in other physiological processes
but are not the primary targets for opioid analgesia.
, 2. A patient is receiving a continuous infusion of morphine via
a patient-controlled analgesia (PCA) pump. The nurse notes
the patient’s respiratory rate has decreased to 8 breaths per
minute. Which medication should the nurse anticipate
administering?
a. Nalbuphine (Nubain)
b. Naltrexone (ReVia)
c. Naloxone (Narcan)
d. Acetylcysteine (Mucomyst)
Correct Solution: c. Naloxone (Narcan)
Rationale: Naloxone is a pure opioid antagonist used to reverse
life-threatening opioid-induced respiratory depression. It
competitively blocks opioid receptors. Nalbuphine is a mixed
agonist-antagonist that could precipitate withdrawal but is not
the first-line reversal agent for respiratory arrest. Naltrexone is an
oral antagonist used for addiction treatment. Acetylcysteine is
used for acetaminophen overdose.
3. A patient with chronic cancer pain has been taking
oxycodone (OxyContin) for several weeks. The patient reports
that the medication is not working as well as it did initially.
The nurse recognizes this as:
