Question
Which of the following is an indication for withholding indirect-acting cholinergic agonists?*1 pointVisual acuity of 20/150Blood pressure of 140/90 mmHgGFR of 30 mL/hourAdult heart rate of 55 beats per minute
Solution
The question is asking for a condition that would indicate the need to withhold indirect-acting cholinergic agonists. The options are visual acuity of 20/150, blood pressure of 140/90 mmHg, GFR of 30 mL/hour, and adult heart rate of 55 beats per minute.
-
Visual acuity of 20/150: This is a measure of vision, and it is not typically a reason to withhold indirect-acting cholinergic agonists.
-
Blood pressure of 140/90 mmHg: This is considered high blood pressure, but it is not typically a reason to withhold indirect-acting cholinergic agonists.
-
GFR of 30 mL/hour: This is a measure of kidney function. A low GFR can indicate kidney disease, but it is not typically a reason to withhold indirect-acting cholinergic agonists.
-
Adult heart rate of 55 beats per minute: This is considered bradycardia, or a slow heart rate. Indirect-acting cholinergic agonists can slow the heart rate further, so they should be used with caution in patients with bradycardia.
So, the answer is an adult heart rate of 55 beats per minute. This is an indication for withholding indirect-acting cholinergic agonists.
