Final answer:
The preferred medication for pain relief during pregnancy is acetaminophen. Unlike other pain relievers like NSAIDs, acetaminophen does not pose an increased risk to the fetus. NSAIDs such as naproxen, diclofenac, and ibuprofen should be avoided during pregnancy due to potential adverse effects on the fetus. The correct answer is option C .
Step-by-step explanation:
When prescribing an analgesic to a pregnant client, the preferred medication is acetaminophen. This medication is considered safe to use during pregnancy for pain relief and reducing fever. Unlike other pain relievers such as NSAIDs (nonsteroidal anti-inflammatory drugs) like naproxen, diclofenac, and ibuprofen, acetaminophen does not have an increased risk of adverse effects on the developing fetus.
Acetaminophen works by reducing the production of prostaglandins, which are chemicals involved in pain and inflammation. It does not have a significant effect on platelet function or increase the risk of bleeding, making it a suitable choice for pregnant women.
Naproxen, diclofenac, and ibuprofen are NSAIDs that work by inhibiting the cyclooxygenase (COX) enzyme, reducing the production of prostaglandins. However, these medications have some concerns during pregnancy. Their use in the third trimester may increase the risk of a heart defect in the fetus and may also cause constriction of blood vessels in the fetal kidney, leading to reduced amniotic fluid levels. Additionally, these NSAIDs can prolong labor and increase the risk of bleeding complications during delivery.
