Excessive blood loss after childbirth can have several causes; the most common is:
unrepaired lacerations of the vagina or cervix.
retained placental fragments.
vaginal or vulvar hematomas.
failure of the uterine muscle to contract firmly.
The Correct Answer is D
The most common cause of excessive blood loss after childbirth is the failure of the uterine muscle to contract firmly, which is also known as uterine atony. If the uterus does not contract effectively after delivery, it cannot properly close off the blood vessels that were connected to the placenta, leading to heavy bleeding. Uterine atony can occur due to various factors, such as prolonged labor, multiple births, or the use of certain medications during labor.
Other causes of excessive blood loss after childbirth include retained placental fragments, vaginal or vulvar hematomas, or unrepaired lacerations of the vagina or cervix, but these are less common than uterine atony.

Correct Answer is C
Explanation
In the case of a bioterrorism attack involving anthrax, the main priority for the nurse is to administer antibiotics within 48 hours of exposure using the Strategic National Stockpile. Anthrax is a serious bacterial infection that can be used as a bioterrorism weapon. Antibiotics, such as ciprofloxacin, doxycycline, and penicillin, can be used to prevent anthrax from developing in people who have been exposed.
There is currently no vaccine available for anthrax exposure. Also, symptom support alone is not enough in cases of anthrax exposure, as anthrax can progress rapidly and lead to serious complications. Placing everyone who was exposed in quarantine may not be necessary in all situations, and should be determined on a case-by-case basis depending on the extent and severity of the exposure.
