Rho(D) immune globulin (RhoGAM) is given to a pregnant woman after delivery and the nurse is giving information to the patient about the indication of the medication. The nurse determines that the patient understands the purpose of the medication if the patient tells that it will protect her baby from which of the following?

Correct Answer: D

Rationale: Rho(D) immune globulin (RhoGAM) is administered to Rh-negative mothers to prevent Rh incompatibility in future pregnancies. It works by preventing the mother's immune system from developing antibodies against Rh-positive fetal blood cells, which could harm subsequent Rh-positive babies. Pernicious anemia and German measles are unrelated to RhoGAM. The medication does not affect the baby's blood type but prevents the mother's immune response. Therefore, Rh incompatibility is the correct answer.

Correct Answer: D

Rationale: Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors in the body. Overdosing on warfarin can lead to excessive bleeding due to the lack of functional clotting factors. To reverse the effects of warfarin overdose, Vitamin K is given because it helps the body restore the levels of clotting factors that were reduced by warfarin. Vitamin K promotes the synthesis of clotting factors II, VII, IX, and X, which allows the blood to clot effectively again. Therefore, in the case of a warfarin overdose, Vitamin K is the appropriate antidote to help reverse the anticoagulant effects.

Correct Answer: B

Rationale: Levonordefrin is a vasoconstrictor that is commonly added to local anesthetic solutions to help reduce bleeding and prolong the anesthetic effect by constricting blood vessels at the injection site. Methylparaben, sodium bisulfite, and sodium pyrosulfite are not vasoconstrictors and do not serve this specific function in local anesthetic solutions.

Correct Answer: D

Rationale: Morphine undergoes extensive first-pass metabolism in the liver, which reduces its oral bioavailability significantly.

Correct Answer: C

Rationale: Diarrhea is the most common complication of enteral therapy, often due to formula composition, administration rate, or bacterial contamination. Aspiration (A) is a serious but less common complication. Constipation (B) and muscle weakness (D) are not typically associated with enteral therapy.
