Which response by a parent of a 24-week-old fetus undergoing intrauterine surgery indicates that the parent understands fetal wound healing?
A) "My baby should have little or no scarring if we do the surgery now."
B) "If we wait for 32 weeks' gestation, my baby will have little or no scarring."
C) "Due to a weak inflammatory response, the wound will not heal as strongly as a wound in an adult."
D) "Fetal wounds heal slower than adult wounds."
A) "My baby should have little or no scarring if we do the surgery now."
Explanation: A) Cutaneous wounds in a fetus younger than 24 weeks of gestation, referred to as an early-gestation fetus, healed with little or no scarring.
B) As the gestational age of the fetus increases, healing proceeds from no scar to barely visible to faint mark to obvious scar.
C) The likelihood of scar development during fetal wound healing is associated with an increasing inflammatory response. Scarless fetal wounds heal with minimal inflammation. The weak inflammatory response in scarless healing is thought to be related to the diminished function of early fetal neutrophils, macrophages, and platelets.
D) Apparently, as the immune system matures and the inflammatory response strengthens, the likelihood of fetal scar formation increases. Cutaneous fetal wounds tend to heal not only without a scar but also more rapidly than adult wounds.

Which statement by a nursing student about the mechanism of action of sulfonamides indicates the need for further instruction?
1. "Sulfonamides resemble the precursor molecule, PABA, so the enzymes needed for the synthesis of folic acid bind with sulfonamide instead of with PABA, stopping bacterial growth." 2. "Sulfonamides slow the growth of bacteria because they only inhibit folic acid that is synthesized by bacteria." 3. "Sulfonamides are effective against uropathogens by inhibiting the synthesis of bacterial folic acid." 4. "Sulfonamides are most effective in clients who eat large amounts of foods rich in folic acid."
