Registered Practical Nurse (RPN) Practice Test

Why is it important for a nurse to obtain baseline blood pressure readings in older adults taking psychiatric medications?

1. To assess for potential drug interactions

2. To monitor for orthostatic hypotension

3. To evaluate kidney function

4. To determine heart health

The correct answer is: To monitor for orthostatic hypotension

Obtaining baseline blood pressure readings in older adults taking psychiatric medications is particularly important for monitoring orthostatic hypotension. This condition refers to a significant drop in blood pressure that can occur when a person moves from a sitting or lying position to standing. Older adults often have decreased physiological reserve, making them more susceptible to fluctuations in blood pressure. Psychiatric medications, especially certain classes like antidepressants and antipsychotics, can further influence blood pressure regulation. Monitoring baseline readings helps healthcare providers identify any changes early, allowing for timely interventions to prevent falls and other complications associated with low blood pressure. Understanding these dynamics is crucial for ensuring safety in this vulnerable population. While assessing for potential drug interactions, evaluating kidney function, and determining heart health are also important aspects of care in older adults, they do not specifically address the immediate risks associated with blood pressure changes related to postural changes.
