RhD alloimmunization occurs when an RhD-negative client is exposed to RhD-positive fetal red blood cells and the maternal immune system recognizes the D antigen as foreign. The immune system may then produce immune anti-D antibodies. The first exposure may not cause severe fetal disease immediately, especially if the antibody response develops slowly. The larger danger is future pregnancy risk. Once maternal immune anti-D antibodies exist, they can cross the placenta in a later RhD-positive pregnancy. These IgG antibodies attach to fetal RhD-positive red blood cells and cause hemolysis. For NCLEX-RN (Canada), items rarely announce the topic in the first sentence. Anchor to objective data, trajectory, and the safest next step for the role named in the stem before distractors compete. On the exam, writers often pair stable-sounding options with unstable data—notice the mismatch before you commit. If the stem names a license or role, reread that line; scope errors are classic trap answers even when the clinical topic is familiar. Run a 60-second scan: breathing work and oxygenation, perfusion and end organs, neuro baseline, likely infection sources, and devices that...
