Final answer:
For a patient with a history of stroke, like Mrs. Harris, the concern is that slower drug absorption may affect the efficacy of slow-release medication, potentially necessitating adjustments in dosage or administration schedule by healthcare professionals.
Step-by-step explanation:
The administration of slow-release medication to a patient with a history of stroke, such as Mrs. Harris, could be affected due to potential slower drug absorption, which may impact the efficacy of the medication. Since strokes can result in lasting damage to various parts of the brain and central nervous system, these changes may alter how the body handles medication, potentially influencing the rate at which it is absorbed and distributed.
Answer choice b) 'Slower drug absorption may affect medication efficacy' is the most relevant complication when considering Mrs. Harris's history of stroke in the context of administering SR medication. It considers that after a stroke, the patient might have altered physiology that could change the absorption, distribution, metabolism, or excretion of drugs.
Healthcare professionals must closely monitor patients with a history of stroke who are receiving slow-release medicines to ensure therapeutic levels are achieved without causing adverse effects. Adjustments in dosage or the administration schedule may be required to accommodate for the changes in drug handling by the body.
