Rationale: Fat emboli syndrome most commonly occur 24-72 hours after a long
bone (femur) fracture. S/S include dyspnea, tachypnea, tachycardia, fever,
confusion, and a reddish-brown non palpable petechial rash over the upper body,
particularly on the chest and axillae.

A patient complains of an excruciating unilateral headache with nasal congestion
and excessive lacrimation on the affected side. The nurse suspects:
a. Migraine
b. Temporal arteritis
c. Sinus headache
d. Cluster headache - ANSWER-d. Cluster headache
Rationale: Excessive tearing/lacrimation, along with unilateral nasal congestions
are signs of a cluster headache. Temporal (Giant cell) arteritis has a palpable cord-
like temporal artery.
A patient complains of cramps left lower quadrant abdominal pain with
alternating episodes of explosive diarrhea and severe constipation. The nurse
knows rehydration is critical since she/he suspects which disorder?
a. Diverticulitis
b. Bowel obstruction

, CEN PRE TEST
Rationale: Diverticulitis is characterized by crampy LLQ pain with alternating
episodes of explosive diarrhea and constipation. It is often caused by a low fiber
diet.
Which highly communicable infection is characterized by swollen salivary and
parotid glands?
a. Mumps
b. Measles
c. Pertussis
d. Diphtheria - ANSWER-a. Mumps

b. Central retinal artery occlusion
c. Retinal detachment
d. Hyphema - ANSWER-b. Central retinal artery occlusion
3|Page
, CEN PRE TEST
Rationale: Painless unilateral vision loss, curtain coming. down, and amaurosis
fugal are seen in central retinal artery occlusion (CRAO). Acute angle glaucoma has
"tunnel vision" and halos around lights. Hyphema is blood in the anterior chamber
of the eye.
Which of the following signs/symptoms should raise an index of suspicion that a
patient is experiencing retinal detachment?
a. "Tunnel vision" and being halos around lights
b. Reddish hue to vision after getting punched in the face
c. Crusty eyelids with yellow discharge from the eye
d. Photopsia and "floaters" in the visual field - ANSWER-d. Photopsia and
"floaters" in the visual field
Rationale: Flashes of light (photopsia) and floaters (spots in vision) are
characteristic of retinal detachment.
A hazardous vulnerability assessment is completed in which phase of disaster
management?
a. Mitigation
b. Preparedness
c. Response
d. Recovery - ANSWER-a. Mitigation
