The nurse is reviewing new medication orders for several patients in a long-term care facility. Which patient does the nurse recognize as being at the highest risk for having cognitive impairment related to prescribed medications?
a. The patient prescribed an antibiotic for a urinary tract infection.
b. The patient prescribed a cholinesterase inhibitor for early Alzheimer's disease.
c. The patient prescribed a beta-blocker for hypertension.
d. The patient prescribed a bisphosphonate for osteoporosis.
ANS: C
Anti-hypertensives such as the beta-blockers can cause adverse changes in cognition. While an infection can affect cognition, antibiotics do not generally cause cognitive changes. The cholinesterase inhibitors are prescribed to slow the progression in cognitive decline for patients diagnosed with Alzheimer's disease. Bisphosphonates are used for osteoporosis and are not generally a risk for altered cognition.
