Which patient does the nurse most closely monitor for an unintended synergistic effect?

ANS: D
The 72 year old seeing four different providers is likely to experience polypharmacy. Polypharmacy places the patient at risk for unintended mixing of medications that potentiate each other. When two medications have a synergistic effect, their combined effect is greater than the effect of the medications when given separately. The child taking too much of a medication by mistake could experience overdose or toxicity. The 50 year old is prescribed two different blood pressure medications for their synergistic effect, but this is a desired, intended event. A patient taking meth and mixing chemicals can be toxic.
