Which side effect is associated with morphine?

• A. Increased heart rate
• B. Nausea
• C. Hyperactivity
• D. Sedation

Answer: (B)

Nausea is a well-known side effect associated with morphine use. This opioid analgesic acts primarily on the central nervous system, and one of its effects is to stimulate the chemoreceptor trigger zone in the brain, leading to feelings of nausea and, potentially, vomiting. Morphine can have various side effects, but nausea is particularly significant due to its frequent occurrence in patients receiving opioid therapy. The other choices, while they may occur in different contexts or with different medications, are not commonly recognized as direct side effects of morphine. For example, increased heart rate is not typically associated with morphine, as opioids often cause a decrease in heart rate, while hyperactivity is not a documented response to morphine administration. Sedation is a potential side effect, but it is distinct from nausea, as nausea specifically involves gastrointestinal discomfort and does not necessarily imply the level of sedation morphine can provide. Focusing on nausea helps clarify how morphine interacts with the body and outlines a common concern for healthcare providers when administering opioids.
