Question 3

Assessment of pupil size and reaction to light provides information about the function of cranial nerves:
III and IV
II and III
I and III
I and II

Correct Answer:

Correct answer: II and III
The optic nerve controls visual fields and visual acuity; the oculomotor nerve controls most extraocular eye movements, ability to elevate eyelid, muscular contraction of the iris in response to light.
* Olfactory Nerve - I
* Optic Nerve - II
* Oculomotor Nerve - III
* Trochlear Nerve - IV
* Trigeminal Nerve - V
* Abducens Nerve - VI
* Facial Nerve - VII
* Vestibulocochlear (Auditory) Nerve - VIII
* Glossopharyngeal Nerve - IX
* Vagus Nerve - X
* Accessory Nerve - XI
* Hypoglossal Nerve - XII

An illustration of the human brain highlights the 12 cranial nerves:
1. The olfactory nerve is located within the nasal cavity below the frontal lobe.
2. The optic nerve emerges from the optic disk in the forebrain.
3. The oculomotor nerve originates from the midbrain of the brainstem.
4. The trochlear nerve originates from the medial midbrain.
5. The trigeminal nerve emerges from the semilunar ganglion near the apex of the temporal bone.
6. The abducens is located on the floor of the fourth ventricle in pons.
7. The facial nerve emerges from pons.
8. The vestibulocochlear nerve is located in pons of the brainstem.
9. The glossopharyngeal nerve emerges from the medulla oblongata.
10. The vagus nerve arises from medulla oblongata.
11. The hypoglossal nerve originates near the top of the spinal cord at the base of the brain.
12. The accessory nerve arises from the cervical spinal cord and caudal medulla.

It is not necessary to wear gloves when handling the respiratory secretions of a patient who has been afebrile for the past 48 hours C. The use of large-volume room-air humidifiers that create aerosols (nebulizers) is acceptable if they can be sterilized at least daily and filled only with sterile water D. Hand washing is not necessary after contact with a respiratory device that is used by a patient when gloves are worn

Question 8

All of the following statements are true concerning ibutilide except:

A. The drug is more effective than procainamide and sotalol in terminating atrial fibrillation and atrial flutter B. Serum potassium and magnesium levels should be measured and corrected before the drug is administered C. The infusion of ibutilide should be stopped in the event of nonsustained or sustained ventricular tachycardia D. The drug causes shortening of the refractory period and action potential duration with little effect on conduction velocity or automaticity
