A patient is experiencing a possible neurological emergency from a blunt force closed head injury. He is found
to have abnormal pupillary reactions to light and has lost the ability to move his eyes from side to side to follow
your finger movements. He is also unable to identify the number of fingers you are holding up. He reports he is
able to see the fingers but is not able to focus enough to identify how many fingers are present.
Which of the following cranial nerves should you suspect may be involved in his injury?
A.
Cranial nerves I, V, and VI
B.
Cranial nerves V and VII
C.
Cranial nerves IX and X
D.
Cranial nerves II, III, and IV - ANSD.
A patient suffering from an ST-elevation myocardial infarction or a presumably new-onset left bundle branch
block may benefit from the use of fibrinolytic therapy if the agent is given promptly. How long does a patient
have to receive the first fibrinolytic agent to salvage ischemic heart tissue?
A.
Within 12 hours of symptoms onset
B.
Within the first 90 minutes from symptom onset
,C.
Within 24 hours of symptoms onset
D.
Within the first hour ("golden hour") from symptom onset - ANSA.
According to the American Heart Association, healthcare providers should not attempt to alter glucose
concentration within a specific range because of the increased risk of hypoglycemia. What is the suggested
range?
A.
60-90 mg/dL
B.
80-110 mg/dL
C.
186-202 mg/dL
D.
110-160 mg/dL - ANSB.
After assisting a full-term pregnant patient in the delivery of her newborn, the newborn remains bradycardic
with a heart rate of 50 beats per minute and exhibits cyanosis around his mouth, nose, fingers, and toes. He is
not responding well and appears lethargic following the five-minute APGAR assessment.
What would be the best initial intervention at this point to increase his heart rate?
A. Deliver adequate artificial ventilation after ensuring a definitive airway
,B. Administer epinephrine 1:10,000 at 0.1 mg/mL intravenously
C. Administer a vasopressor agent intravenously per medical command recommendations
D. "Fast and hard" chest compressions at more than 120 compressions per minute - ANSA.
After assisting a pregnant patient to deliver her full-term newborn at home, you quickly dry the infant and
open his airway to help begin spontaneous respiration. However, after a few seconds, you realize the newborn
has copious secretions in his airway preventing effective spontaneous respiration.
Which of the following should you do to safely and effectively clear the infant's airway?
A. Use a portable suction machine with a rigid suction catheter to suction his posterior airway
B. Use a bulb syringe to suction his nose first and his mouth second
C. With assistance, use two bulb syringes to suction his mouth and nose simultaneously
D. Use a bulb syringe to suction his mouth first and then his nose second - ANSD.
After attempting to slow the bleeding associated with natural childbirth by non-invasive means, your patient
continues to bleed significantly. Per medical direction, after ensuring a second fetus is not present, which of the
following would be the most appropriate intervention for the new mother?
A.
Rapidly administer a 2-3 liter glucose-containing IV solution such as D5W using a pressure infusion
B.
Place ice packs on the abdomen and at the opening of the birth canal to promote clotting
, C.
Mix 10 units of oxytocin to 1 liter of lactated Ringer's solution and run at 20-30 gtts/min
D.
Apply firm, direct pressure to the area above the pubic bone while inserting a sterile ABD pad into the opening
of the birth canal - ANSC.
After intubating your apneic patient, what tube placement confirmation means should be assessed first?
A.
Auscultate each lung field for the presence of breath sounds
B.
Attach capnography to determine the presence of ventilatory waveform
C.
Attach an end-tidal carbon dioxide detector
D.
Auscultate over the epigastric region for the presence or absence of breath sounds - ANSD
An adult asthma patient is experiencing laryngospasm and ineffective respirations, making orotracheal
intubation impossible. So, you quickly decide to perform nasotracheal intubation. Which of the following tubes
would be most appropriate for the procedure for an average height and weight adult?
A.
Cuffed 6.0-6.5 mm endotracheal tube
B.
