Answer:
If a vial of morphine has 10 mg/mL, and a dose of 4 mg is required to be administered intravenously, 04 mL must be administered to fulfill the indication.
Step-by-step explanation:
Morphine is a drug, an opioid derivative, with a potent analgesic and sedative effect. Its use is intended for acute or chronic severe pain, mainly related to cardiovascular disease, cancer or severe trauma.
One vial of morphine vial has a concentration of 10 mg/mL, so if 4 mg is required, a simple calculation must be made:
Morphine: 10 mg ------------ 1 mL
Dose: 4 mg ------------ X
X = (4 x 1)/ 10
X = 4/10
X = 0.4 mL
To administer 4 mg of intravenous morphine, 0.4 mL of the injection should be used.
