NR 547 CEA Exam Study Guide – Full Part 1 (1–74)
1. Suspicion while percussing the liver Answer: Percussion changes from dull to tympany
(left anterior axillary line → left sternal border)
Rationale: Suggests gastric air bubble or enlarged left lobe of the liver.
2. Assessing ROM of the shoulder, 26 y/o Answer: Rotator cuff injury
Rationale: Pain or weakness with shoulder abduction or external rotation.
3. Unequal shoulder height, lateral spinal curve Answer: Scoliosis
Rationale: Spinal curvature causes asymmetry of shoulders and scapulae.
4. Awful taste sensation name Answer: Gustatory
Rationale: Gustatory sense relates to taste perception.
5. Macrocytic anemia in 43 y/o male Answer: Vitamin B12 deficiency
Rationale: B12 deficiency causes large RBCs (macrocytosis).
6. 24 y/o erythema on face treatment Answer: Doxycycline
Rationale: Common antibiotic for acne or rosacea.
7. Testing for hyperthyroidism Answer: TSH and Free T4 (Thyroid-Stimulating Hormone,
Thyroxine)
Rationale: Confirms thyroid function status.
8. Systemic lupus erythematosus hallmark Answer: Butterfly rash on face
Rationale: Typical malar rash pattern sparing nasolabial folds.
9. Elderly w/ retinal detachment pneumopexy Answer: Posterior only
Rationale: Gas bubble tamponade applied to posterior retina.
10. Highest level of research quality Answer: Systematic review
Rationale: Combines multiple studies to give strongest evidence.
11. Hyperthyroid crisis symptom Answer: Tachycardia
Rationale: Sign of thyroid storm and adrenergic overactivity.
12. Second oral anti-diabetic agent when A1C 8.0% Answer: Add 2nd agent (e.g., GLP-1
agonist or SGLT2 inhibitor)
, Rationale: Dual Therapy When Metformin Monotherapy Insufficient.
13. Drug Not Used As Monotherapy For Asthma Answer: Long-Acting Beta-Agonist
(LABA) Rationale: LABA Increases Mortality Risk If Used Without Corticosteroid.
14. Hematuria Post-Strep Infection Answer: Glomerulonephritis
Rationale: Post-Streptococcal Immune Response Damages Glomeruli.
15. Enlarged Object To Be Removed Answer: Thymic Remnant
Rationale: Thymus Tissue May Persist And Enlarge Abnormally.
16. PAD Treatment Agent Answer: Cilostazol (Pletal)
Rationale: Improves Claudication By Vasodilation And Antiplatelet Effects.
17. Gag Reflex Impaired Nerve Answer: Glossopharyngeal (CN IX)
Rationale: Controls Pharyngeal Sensation And Gag Response.
18. SSRI, SNRI, MAOI Risk When Combined Answer: Serotonin Syndrome
Rationale: Results From Excessive Serotonergic Activity.
19. Scrotum Full Feeling Answer: Varicocele
Rationale: Dilation Of Pampiniform Venous Plexus, ‘Bag Of Worms’ Feel.
20. Decreased Reflexes, Confusion, Flushing, Hypotension Answer: Magnesium Toxicity
Rationale: Excess Mg Depresses CNS And Reflexes.
21. Early Renal Dysfunction In DM/HTN Test Answer: Urinalysis With Microalbumin
Rationale: Detects Early Kidney Damage.
22. Abdominal Pain But No Rebound Tenderness Answer: Not Peritonitis
Rationale: Lack Of Rebound Pain Indicates No Peritoneal Inflammation.
23. CKD, DM, Hypothyroidism (TSH 9) Answer: Cold Intolerance
Rationale: Symptom Of Hypothyroidism Due To Low Metabolism.
24. S3/S4 Murmur Phase Answer: Diastole
Rationale: Extra Heart Sounds Occur During Ventricular Filling.
25. Understanding Dialysis Answer: Blood Cleansed Via Semipermeable Membrane
