- 2. You are preparing to sedate a patient with fentanyl and versed. What supplies and/or medications should you have available at the bedside? 3. You are the nurse in the surgery suite caring for a patient. You look at the anesthesia monitor and see that the patient's blood pressure continues to decline with every 5- minute blood pressure reading, and has been trending this way since anesthesia was started. The anesthesiologist has not said anything to the surgeon, and is adjusting medications, so you continue to monitor your patient and assist with the procedure when necessary. A few minutes later, you notice that your patient's blood pressure has fallen to 56/30, and the anesthesiologist is appearing flustered, but still has not said anything to the surgeon. The surgeon asks you if everything is OK. What do you do?8. A patient is to be started on an intravenous infusion of heparin for a DVT. The MD orders 50,000 units in 1 liter of NSS.

- 7. A phlebotomist has a requisition to collect an ABG specimen from a patient in the cardiac care unit (CCU). The phlebotomist identifies the patient and records the required requisition information. The patient has an IV in the left arm in the area of the wrist, so the phlebotomist chooses the right arm. The patient is having difficulty breathing and appears quite restless and agitated. The phlebotomist performs the modified Allen test. The result is positive. The phlebotomist attempts puncture of the radial artery. The patient moves his arm as the needle is inserted and it misses the artery. The phlebotomist redirects the needle several times and finally hits the artery. The blood pulses into the syringe but is dark reddish-blue in color. The phlebotomist completes the draw, removes the needle, holds pressure over the site, and at same time activates the needle safety device, removes the needle, and caps the syringe, being careful not to introduce air bubbles into it.
