Test Bank Review and Advanced Study
Guide for Certification Preparation
Question 1:
A patient undergoes a Snellen visual acuity test and records 20/30 in the left eye and
20/40 in the right eye. What is the most appropriate interpretation?
A. Normal visual acuity
B. Immediate ophthalmology emergency
C. Mild visual impairment requiring further evaluation
D. Complete vision loss in one eye
Correct Answer: C. Mild visual impairment requiring further evaluation
Rationale:
Visual acuity of 20/20 is considered normal. A result of 20/30 or 20/40 indicates
reduced visual sharpness, meaning the patient sees at 20 feet what a normal eye sees
at 30–40 feet. While not an emergency, this finding requires further evaluation to rule
out refractive errors or early ocular disease. Options A and D are incorrect because
the vision is not normal or lost, and option B is incorrect because this is not an acute
emergency finding.
Question 2:
A caregiver intentionally fabricates or induces illness in a dependent child for
attention. This condition is known as:
A. Factitious disorder imposed on self
B. Malingering
C. Munchausen syndrome by proxy
D. Somatic symptom disorder
Correct Answer: C. Munchausen syndrome by proxy
Rationale:
Munchausen syndrome by proxy (factitious disorder imposed on another) involves a
caregiver deliberately producing or exaggerating illness in someone under their care.
It is a form of abuse requiring immediate reporting. Malingering involves external
incentives, and factitious disorder imposed on self involves self-induced symptoms.
Somatic symptom disorder involves genuine distress without intentional deception.
,Question 3:
Which medication is commonly used off-label for migraine prophylaxis?
A. Sumatriptan
B. Amitriptyline
C. Albuterol
D. Metronidazole
Correct Answer: B. Amitriptyline
Rationale:
Amitriptyline, a tricyclic antidepressant, is widely used for migraine prevention due to
its effects on serotonin and norepinephrine pathways. Sumatriptan is used for acute
attacks, not prevention. Albuterol is a bronchodilator, and metronidazole is an
antibiotic.
Question 4:
A dark, raised lesion with irregular borders and asymmetry is most suggestive of:
A. Basal cell carcinoma
B. Squamous cell carcinoma
C. Melanoma
D. Seborrheic keratosis
Correct Answer: C. Melanoma
Rationale:
Melanoma typically presents with ABCDE features: asymmetry, border irregularity,
color variation, diameter >6 mm, and evolving characteristics. Basal and squamous
cell carcinomas have different clinical appearances, and seborrheic keratosis is benign.
Question 5:
Periorbital edema with a puffy, non-pitting appearance is most consistent with:
A. Heart failure
B. Nephrotic syndrome
C. Liver cirrhosis
D. Allergic rhinitis
Correct Answer: B. Nephrotic syndrome
Rationale:
Nephrotic syndrome causes hypoalbuminemia leading to decreased oncotic pressure
,and generalized edema, often first noticed around the eyes. Heart failure causes
dependent pitting edema, not periorbital puffiness.
Question 6:
Which condition is commonly treated with short-acting beta agonists (SABA)?
A. Hypertension
B. Acute asthma exacerbation
C. Diabetes mellitus
D. Hyperlipidemia
Correct Answer: B. Acute asthma exacerbation
Rationale:
SABAs such as albuterol are first-line rescue medications for acute bronchospasm in
asthma. They act quickly to relax airway smooth muscle.
Question 7:
A Rh-negative pregnant woman should receive Rho(D) immunoglobulin at:
A. 12 weeks
B. 20 weeks
C. 28 weeks
D. After delivery only
Correct Answer: C. 28 weeks
Rationale:
Rho(D) immunoglobulin prevents Rh sensitization in Rh-negative mothers. It is
routinely given at 28 weeks and again postpartum if the newborn is Rh-positive.
Question 8:
Mean corpuscular volume (MCV) measures:
A. White blood cell count
B. Hemoglobin concentration
C. Size of red blood cells
D. Platelet activity
Correct Answer: C. Size of red blood cells
, Rationale:
MCV classifies anemia: microcytic (low MCV), normocytic, and macrocytic (high
MCV). It helps identify causes such as iron deficiency or vitamin B12 deficiency.
Question 9:
A key contraindication for combined oral contraceptives includes:
A. Acne
B. Smoking in women over 35
C. Mild anemia
D. Irregular menstruation
Correct Answer: B. Smoking in women over 35
Rationale:
Estrogen-containing contraceptives increase thromboembolic risk, especially in
smokers over 35. This significantly increases cardiovascular risk.
Question 10:
Sudden bloody nipple discharge most likely indicates:
A. Normal lactation
B. Benign fibrocystic changes
C. Possible breast malignancy
D. Hormonal imbalance only
Correct Answer: C. Possible breast malignancy
Rationale:
Spontaneous unilateral bloody discharge is concerning for intraductal papilloma or
breast cancer and requires urgent evaluation.
Question 11:
Which medication is contraindicated for migraine prophylaxis due to adverse effects?
A. Amitriptyline
B. Venlafaxine
C. Propranolol
D. Topiramate
Correct Answer: B. Venlafaxine
