Solutions
Microshock - ANSWER-leaking current from electrical unit can travel down saline filled
catheter
Allen Test - ANSWER-Performed before placing A-line - occlude both radial and ulnar
and then occlude just the one they will use for the A-line to make sure the other one
alone will be enough to sustain
During a local procedure, patient suddenly becomes restless. Immediate response is to:
- ANSWER-check airway
During an abdominal hysterectomy on a pt with hemoglobin of 10 and hematocrit of 30,
the RN notices 600ml of bloody fluid in the suction. In this case, the RN would first: -
ANSWER-Ask the scrub nurse how much irrigation has been used and subtract this
amount from the 600ml to estimate blood loss.
Hemoglobin, Men - ANSWER-13.5-17.5 (14-18)
Hemoglobin, Women - ANSWER-12-15.5 (12-16)
Hematocrit, Men - ANSWER-40-54%
Hematocrit, Women - ANSWER-36-48%
During emergency induction of anesthesia, the perioperative nurse may request to use
the Selleck's maneuver (cricoid pressure) to: - ANSWER-Control regurgitation of
stomach contents
A common property of general anesthesia is: - ANSWER-Vasodilation
Symptoms of benzodiazepine overdose include: - ANSWER-Confusion, coma, ad
decreased respiratory function
A 20min carpal tunnel procedure has been completed. The splint and bulky dressing are
in place. Pt had a Beir Block without additional IV sedation. The interventions that would
be most relevant to the patient's postoperative recovery would be for the perioperative
nurse to: - ANSWER-Protect the patient's arm until muscle control and full sensation
returns.
, A patient who is having a breast biopsy under local anesthesia of 1% lidocaine with
epinephrine begins to exhibit tremors, palpitations, and tachycardia. These signs are
most likely a result of: - ANSWER-a reaction to the vasoconstrictor
Pt is about to undergo ORIF of her ankle. The surgeon requests the use of the
pneumatic tourniquet. To prevent neurovascular damage, the RN should apply the cuff
to: - ANSWER-The point of maximum circumference
How wide should the tourniquet cuff be? - ANSWER-The width of the cuff should be
wider than half the limb's diameter.
The tourniquet cuff should overlap: - ANSWER-at least three inches but not more than 6
inches.
LOP (Limb Occlusion Pressure) can be defined as - ANSWER-the minimum pressure
required to stop the flow of arterial blood into the limb distal to the cuff
Cuff inflation pressure should be adjusted by adding a safety margin to the LOP: -
ANSWER-Add 40 mmHg for LOP <130 mmHg
Add 60 mmHg for LOP between 131 and 190 mmHg
Add 80 mmHg for LOP >190 mmHg
For pediatric patients, adding 50 mmHg has been recommended.
Which of the following factors must be considered when applying and inflating the
tourniquet? - ANSWER-Patient's age, limb occlusion pressure, size of extremity, and
vascular supply

of the following positions should the patient be placed to facilitate draining? - ANSWER-
Semiprone

Witness pt? - ANSWER-Autotransfusion, volume expanders, cardiopulmonary bypass
