GQ-119. PHARMACIST'S MATES
Explanatory Note.
General quarters duties of pharmacist's mates consist entirely of care for personnel casualties and the sick. Depending upon ability, resourcefulness, and experience as required by the Bureau of Medicine and Surgery and reflected by grade in rate, pharmacist's mates are called upon for first aid; for splinting, bandaging, and treatment for shock, burns, and hemorrhage; for minor surgery, suturing, and intravenous injections; and for administering anaesthesia and assisting with emergency major surgery. Destroyer pharmacist's mates are required to be especially capable because few are assigned to the ship, and reliability in independent action is of great importance.
