Genotyping affects patient care in several ways: - Personalized Treatment: It helps in tailoring treatments based on individual genetic profiles, ensuring that patients receive the most effective medications with the least side effects. - Disease Prevention: By identifying genetic predispositions, nurses can work with patients on preventive measures to reduce the risk of developing certain conditions. - Medication Management: Genotyping can reveal how patients metabolize certain drugs, guiding nurses in dosage adjustments and avoiding adverse drug reactions.
