Final answer:
Misoprostol is administered rectally to treat postpartum hemorrhage by inducing uterine contractions that help to control bleeding. The correct answer to the question is 'D. rectally.'
Step-by-step explanation:
In the treatment of postpartum hemorrhage (PPH), the correct route of administration for misoprostol is rectally. Misoprostol is a medication that has been shown to be effective in stopping hemorrhage when other first-line treatments, like oxytocin, are not available or contraindicated. It can be administered rectally which is particularly useful in settings where intravenous routes might be challenging to establish or not available.
Misoprostol tablets are generally administered in the rectal route in doses of 800-1000 micrograms for the treatment of PPH. This medication acts on the smooth muscle of the uterus to induce contractions, which helps to compress the blood vessels and reduce bleeding.
