CEN Exam Questions AND Correct Answers
"blow in" orbital fx - ✔✔bone fx into orbit towards the eye
exopthalmos or eye bulging
occurs with impact to lateral side of face
"blow out" orbital fx - ✔✔bone fractures away from eye
enopthalmos
occurs with direct blow to the eye
1st and 2nd rib fx concerns - ✔✔great vessel
(subclavian/aorta) and lung injury
4 elements needed to prove medical negligence - ✔✔DUTY:
the nurse has a duty to perform care
BREACH OF DUTY: the person failed to complete that duty
,CAUSATION: the breach of duty caused damage
DAMAGE: damage exists
9th-12th rib fx concerns - ✔✔spleen and liver injury
abnormal ICP - ✔✔sustained >20 mmHg
abruptio placentae - ✔✔premature separation of the placenta
from the uterine wall, causing hemorrhage and shock.
S/S: contractions with uterine rigidity and backache, dark,
frank blood, abnormal FHT's
TX: blood products STAT and prepare for C-section
ACE inhibitors adverse effects - ✔✔dry cough, angioedema,
renal impairment
,achilles tendon rupture - ✔✔higher risk if on flouroquinolones
(cipro, levaquin)
acid ocular burns - ✔✔irrigate with LR
acute angle closure glaucoma - ✔✔increase in IOP,
compression of optic nerve
***blindness within hours if left untreated
tunnel vision, halos around lights; fixed &dilated pupil, cloudy
cornea, firm feeling globe
TX: elevate HOB, decrease IOP, miotic drops, topical beta
blockers
D/C teaching: immediate ophthalmology consult/ follow up;
no lifting, no lowering head below waist; avoid
coughing/straining
, acute renal failure - ✔✔rapid loss of renal function (less than
400 ml/day in adults, less than 0.5 ml/kg/hr in children)
adrenal crisis/addison's disease - ✔✔CAUSES: sudden
discontinuation of glucocorticoids, infection, trauma, surgery
S/S: tachycardia, hypotension, hyponatremia, hypoglycemia
and hyperkalemia
TX: treat hypovolemic shock with NS, replace glucocorticoids
airborne precautions - ✔✔negative pressure room, N-95 mask
(TB, pertussis, influenza)
alkali burns (cement, lye, ammonia) - ✔✔cause liquefaction,
large amounts of copious irrigation needed
alkali ocular burns - ✔✔requires large amounts of irrigation
with normal saline
