Answer to Question 1

1,3
Rationale 1: An overdose of phenylephrine (Neo-Synephrine) will result in tachycardia.
Rationale 2: Feelings of anxiety and restlessness are expected adverse effects of phenylephrine (Neo-Synephrine).
Rationale 3: Overdosage of phenylephrine (Neo-Synephrine) will result in hypertension.
Rationale 4: Dark and tarry stools are not related to phenylephrine (Neo-Synephrine).
Rationale 5: Burning at the injection site would indicate possible extravasation, not overdose.

Global Rationale: An overdose of phenylephrine (Neo-Synephrine) will result in tachycardia and hypertension. Feelings of anxiety and restlessness are expected adverse effects of phenylephrine (Neo-Synephrine). Dark and tarry stools are not related to phenylephrine (Neo-Synephrine). Burning at the injection site would indicate possible extravasation, not overdose.

Answer to Question 2

2,3
Rationale 1: There is no particular reason that bowel sounds should be monitored more frequently than normally done.
Rationale 2: Clevidipine (Cleviprex) is administered intravenously.
Rationale 3: Clevidipine (Cleviprex) has an ultrashort half-life so blood pressure will be monitored continuously.
Rationale 4: This drug is not supplied in caplet form.
Rationale 5: Infusing normal saline at this rate would be contraindicated in hypertensive emergency.
