NR 667 CEA EXAM 2026 CERTIFICATION
EVALUATION QUESTIONS AND SOLUTIONS
COMPLETE STUDY SHEET FINAL PREP 450
◉ Gram negative rods.
Answer: Perforated ulcers and resultant peritonitis often involve
gram-negative enteric organisms (e.g., E. coli).
◉ Hydrocele.
Answer: A fluid-filled scrotal enlargement that can transilluminate is
most consistent with a hydrocele.
◉ Leaning forward.
Answer: Sinus pressure typically worsens when bending or leaning
forward.
◉ Lymphoma.
Answer: 'B symptoms' (night sweats, weight loss) plus hilar
lymphadenopathy strongly suggests lymphoma.
◉ Ehlers-Danlos.
,Answer: Ehlers-Danlos syndrome, a connective tissue disorder, can
be linked to vitreous abnormalities.
◉ Homonymous hemianopia.
Answer: Loss of the right visual field in both eyes is a right
homonymous hemianopia (post-chiasmal lesion).
◉ TIBC and ferritin.
Answer: Iron studies (especially serum ferritin, TIBC) confirm iron
deficiency (the most common cause of microcytosis with high RDW).
◉ Thalassemia trait.
Answer: Thalassemia typically shows microcytosis with normal RBC
distribution width, as opposed to iron deficiency (which raises
RDW).
◉ Vitamin B12.
Answer: Macrocytosis suggests checking B12 or folate to
differentiate causes.
◉ Normal MCH, hemoglobin 9.6.
Answer: ESRD often causes a normocytic, normochromic anemia
(low hemoglobin, but normal indices).
,◉ Aspirin use.
Answer: Reye syndrome in children has been associated with aspirin
administration during viral illnesses.
◉ IgM.
Answer: IgM anti-HAV rises early in acute hepatitis A infections.
◉ Hepatitis Core antibody.
Answer: After about a year, the IgG core antibody (anti-HBc)
typically remains positive in ongoing or past HBV infection.
◉ Antinuclear antibody.
Answer: ANA testing is the primary screening test for SLE.
◉ Apocrine.
Answer: Apocrine sweat gland obstruction (e.g., in hidradenitis
suppurativa) often leads to abscess formation.
◉ Irregular border.
Answer: An irregular or poorly demarcated border is a classic red
flag for melanoma.
◉ Actinic keratosis.
, Answer: Actinic (solar) keratoses are considered premalignant
lesions from sun (UV-B) damage.
◉ Diameter of 0.8 cm.
Answer: Lesions >6 mm (0.6 cm) in diameter are concerning ("D" in
ABCDE). At 0.8 cm, it's suspicious.
◉ GABA.
Answer: Alcohol enhances GABA; withdrawal states lead to relative
GABA deficiency, causing hyperadrenergic symptoms.
◉ TSH and free T4.
Answer: Thyroid function tests help rule out hyperthyroidism, which
can mimic anxiety symptoms.
◉ Olfactory.
Answer: Perceiving nonexistent odors is an olfactory hallucination.
◉ Depression.
Answer: Depression is the most frequent psychiatric condition co-
existing with self-harm/suicidality.
◉ Damage to the rotator cuff.
