See the syringe diagram, what part is #7? (Assuming #7 refers to a common syringe part; no diagram provided, so standard parts assumed.)

Choice A reason: Multiple pharmacies increase polypharmacy risk; 16 prescriptions across four sources raise chances of duplication or interactions, lacking centralized oversight.

Choice B reason: Five hypertension drugs signal polypharmacy; excessive medications for one condition heighten interaction risks, potentially causing adverse effects or toxicity.

Choice C reason: Daughter’s help with eyedrops aids compliance; this single-task assistance doesn’t inherently increase drug numbers or polypharmacy-related risks.

Choice D reason: Weekly warfarin tests monitor safety; this manages one drug’s effect, not indicating polypharmacy, but rather appropriate therapeutic oversight.

Choice E reason: Allergies affect drug choice, not quantity; this doesn’t contribute to polypharmacy, as it’s a sensitivity issue, not a medication count concern.

Choice A reason: Narcotics are controlled substances requiring strict accountability; two nurses—one ending and one starting the shift—verify counts to ensure accuracy and prevent diversion per regulatory standards.

Choice B reason: The head nurse and pharmacist may oversee inventory, but shift change counts involve direct caregivers for real-time accuracy, not administrative staff, ensuring immediate responsibility and oversight.

Choice C reason: Involving all nurses from both shifts is impractical and unnecessary; it dilutes accountability and increases error risk, as only two are needed to confirm the count efficiently.

Choice D reason: Pharmacy technicians lack authority over unit narcotics, and the charge nurse alone doesn’t suffice; two nurses ensure a witnessed, reliable count per hospital policy and law.
