Question 4 of 5
Adverse effect of morphine include all of the following EXCEPT:
Correct Answer: D
Rationale: Morphine's adverse effects stem from mu receptor agonism. Physical and psychological dependence (choice A) arises from chronic use, activating reward pathways. Constipation (choice B) results from reduced GIT motility, a common issue requiring laxatives. Respiratory depression (choice C), the most dangerous, depresses brainstem respiratory centers, critical in overdose. Hyperpyrexia (choice D), or fever, is not a morphine effect; opioids typically cause hypothermia in overdose due to CNS depression, unlike stimulants. This exception highlights morphine's depressant profile, essential for monitoring and distinguishing it from other drug classes causing hyperthermia.
Question 5 of 5
Aspirin is useful in treatment of:
Correct Answer: B
Rationale: Aspirin treats simple headaches (choice B) via COX inhibition, reducing prostaglandin-mediated pain. Bronchial asthma (choice A) may worsen with aspirin due to leukotriene shifts. Peptic ulcer (choice C) is contraindicated due to GI irritation. Viral infections in children (choice D) risk Reye's syndrome with aspirin. Headache relief is a standard use, reflecting its analgesic efficacy.
