What is a significant adverse reaction to morphine?

• A. Dehydration
• B. Bronchospasm
• C. Itchy skin
• D. Increased heart rate

Answer: (B)

Morphine, as an opioid analgesic, can lead to a range of adverse reactions; among them, bronchospasm is significant due to its potential to cause respiratory complications. Opioids like morphine can lead to histamine release, which may result in bronchial smooth muscle contraction, making breathing more difficult for individuals with pre-existing respiratory issues. Bronchospasm can be particularly dangerous, especially in patients with asthma or chronic obstructive pulmonary disease (COPD), as it can exacerbate their condition and lead to respiratory distress. Other reactions such as dehydration, itchy skin, and increased heart rate, while certainly relevant in the context of morphine use, are not as acutely concerning in the same way that bronchospasm is. Dehydration is generally more associated with other factors rather than a direct result of morphine. Itchy skin, often due to histamine release, can occur but doesn't pose immediate life-threatening risks like severe bronchospasm can. Increased heart rate can happen but is less common and typically does not reach the critical nature of respiratory complications, which can be life-threatening. Thus, bronchospasm stands out as a significant adverse effect necessitating careful monitoring in patients receiving morphine.
