Which of the following mechanisms is responsible for the phenomenon of immunological memory, wherein the immune system mounts a faster and more robust response upon re-exposure to a previously encountered pathogen?
- A. Clonal expansion of memory B cells
- B. Differentiation of na(cid:239)ve T cells into effector T cells
- C. Production of antibodies by plasma cells
- D. Activation of the complement system
Correct Answer: A
Rationale: Immunological memory is primarily maintained by the clonal expansion of memory B cells. Memory B cells are a type of long-lived immune cell that originates from previously activated B cells during an immune response to a pathogen. When the immune system encounters the same pathogen again, memory B cells can quickly recognize and respond to it by undergoing rapid clonal expansion and differentiation into plasma cells that produce specific antibodies. This quick and robust response leads to the more efficient elimination of the pathogen during secondary exposure, resulting in the faster and stronger immune response characteristic of immunological memory.

The nurse educator Adalynn reviewed the risk factors for postpartum hemorrhage for the mothers. Which of the following factors IS NOT included ____?
- A. ruptured uterus
- B. uterine atony
- C. overdistended uterus
- D. retroversion of the uterus
Correct Answer: D
Rationale: Postpartum hemorrhage (PPH) is a significant complication after childbirth. The risk factors for PPH that are typically included in the list are uterine atony, overdistended uterus (e.g., multiple gestation or polyhydramnios), and ruptured uterus. Retroversion of the uterus is not a known risk factor for PPH. Retroversion refers to the position of the uterus, where it is tilted back towards the rectum. While retroverted uterus can sometimes lead to other issues or complications during pregnancy, it is not directly associated with an increased risk of postpartum hemorrhage.

Which of the following is caused by the markedly distended uterus and intermittent uterine contractions within 2 to 3 days after birth?
- A. Retained placenta
- B. Uterine atony
- C. Afterpains
- D. Boggy uterus
Correct Answer: B
Rationale: Uterine atony is caused by the markedly distended uterus and intermittent uterine contractions within 2 to 3 days after birth. It is characterized by the inability of the uterus to contract after delivery, leading to excessive bleeding postpartum. This condition is a significant risk factor for postpartum hemorrhage. Treatment may involve massage of the uterus, administration of uterotonics, and in severe cases, surgical interventions such as a hysterectomy. Retained placenta refers to incomplete expulsion of the placenta after delivery. Afterpains are the discomfort felt by some women as their uterus contracts and returns to its normal size after childbirth. A boggy uterus is another term for a uterus that feels soft, lax, or lack firm tone, which can be a sign of uterine atony.
