Question

Match the medications in these classifications to their precautions

1. Give with MD present due to risk of bradycardia and wheezes    2. Contraindicated for people with glaucoma or urine retention problems 3.    Watch urine output when giving as a critical drip due to nephrotoxicity 4.   Hold if blood pressure below 100 systolic or if pulse is below 60

A. Adrenergic blockers B. Anticholinergics C. Adrenergics D. Cholinergics

Answer 1

1. Give with MD present due to risk of bradycardia and wheezes - Cholinergics. These drugs decrease the heart rate, blood pressure and increase the tone of smooth muscles. they also increase the secretions like gastrointestinal and tracheo-bronchial, hence they cause difficulty in breathing.
2. Contraindicated for people with glaucoma or urine retention problems - Anticholinergics. These drugs can reduce all the secretions thus cause constipation, urine retention, dilation of pupil, bronchodilatation. Thus to prevent further complications these drugs are contraindicated for people with glaucoma and urine retention.
3. Watch urine output when giving as a critical drip due to nephrotoxicity - Adrenergics. These drugs cause renal vasoconstriction resulting in a fall in renal blood flow, thus urine output should be carefully monitored.
4. Hold if blood pressure below 100 systolic or if pulse is below 60 - Adrenergic blockers. These drugs decrease the heart rate, force of contraction and cardiac output. Blood pressure also falls, hence not given when systolic bp is below 100 and pulse is below 60.
