CNOR Prep Exam
Microshock *** leaking current from electrical unit can travel down saline filled catheter
Allen Test *** 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: *** 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: *** Ask the scrub nurse how much
irrigation has been used and subtract this amount from the 600ml to estimate blood loss.
Hemoglobin, Men *** 13.5-17.5 (14-18)
Hemoglobin, Women *** 12-15.5 (12-16)
Hematocrit, Men *** 40-54%
Hematocrit, Women *** 36-48%
During emergency induction of anesthesia, the perioperative nurse may request to use the Selleck's
maneuver (cricoid pressure) to: *** Control regurgitation of stomach contents
A common property of general anesthesia is: *** Vasodilation
Symptoms of benzodiazepine overdose include: *** 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: *** 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: *** 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: *** The point of maximum
circumference
How wide should the tourniquet cuff be? *** The width of the cuff should be wider than half the limb's
diameter.
The tourniquet cuff should overlap: *** at least three inches but not more than 6 inches.
LOP (Limb Occlusion Pressure) can be defined as *** 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: *** 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? ***
Patient's age, limb occlusion pressure, size of extremity, and vascular supply
, After transfer of the pediatric tonsillectomy patient to the transportation vehicle, in which of the
following positions should the patient be placed to facilitate draining? *** Semiprone
An 8 year old boy is being prepared for bilateral inguinal herniorrhaphy. As the anesthesia provider is
about the start the IV, the boy begins to cry. The most appropriate action at this point would be to: ***
Give the patient psychological support through tactile contact and verbal reassurance
Which is a major stressor on toddlers in the OR? *** Separation anxiety
During Mr. J's lobectomy, the RN notes the following values: CVP = 2, Arterial BP = 90/60. These values
are most likely related to: *** volume depletion
Which intervention would NOT be appropriate to combat fluid deficit in a Jehovah's Witness pt? ***
autologous blood administration
Which intervention WOULD be appropriate to combat fluid deficit in a Jehovah's Witness pt? ***
Autotransfusion, volume expanders, cardiopulmonary bypass
For a patient with a ruptured aortic aneurysm, which method would provide for the safest and most
immediate blood replacement *** Autotransfusion
During the periop interview one week before surgery, a pt is scheduled for a right hip arthroplasty and
expresses a fear of contracting AID from the receiving blood blank. The RN first action would be: ***
Notify the surgeon
Pt list the following meds she is on: Timolol and Pilocarpine for Glaucoma, and metoprolol and diazoxide
for hypertension. The preop meds ordered for her consist of atropine, demerol, and hydroxyzine IM on
call. The RN should be awake of that: *** this preop med set is contraindication for this patient
