Question 1 of 5
Morphine is useful in treatment of:
Correct Answer: A
Rationale: Morphine treats acute abdominal pain (choice A), like postoperative pain, via mu agonism, though diagnosis is key due to masking. Head injury (choice B) contraindicates it due to respiratory depression and ICP rise. Bronchial asthma (choice C) worsens with respiratory suppression.

Question 5 of 5
Both the older (tricyclic) antidepressants and the newer ones (e.g. fluoxetine) relieve signs and symptoms of depression mainly by doing which one of the following things?
Correct Answer: C
Rationale: TCAs (e.g., imipramine) and SSRIs (e.g., fluoxetine) (choice C) block reuptake of serotonin and/or norepinephrine, increasing synaptic levels to treat depression. Blocking receptors (choice A, B) or stimulating serotonin (choice D) aren't primary mechanisms. Reuptake inhibition is their shared action.
