TESTING EXAM 2 VERSIONS WITH ACTUAL QUESTIONS AND DETAILED ANSWERS
WITH A STUDY GUIDE
Question 1
A 28-year-old patient presents with chronic, persistent worry, difficulty staying focused on tasks
at work, and increased irritability over the last 7 months. Which of the following is a hallmark
characteristic of Generalized Anxiety Disorder (GAD)?
A) Tangential thoughts and delusions
B) Impaired concentration and irritability
C) Flashbacks and hypervigilance
D) Disorganized behavior and suspiciousness
E) Grandiosity and decreased need for sleep
Correct Answer: B) Impaired concentration and irritability
Rationale: Generalized Anxiety Disorder (GAD) is characterized by excessive,
uncontrollable worry about various aspects of life. Major clinical characteristics include
physical symptoms such as muscle tension, as well as cognitive and emotional symptoms
like impaired concentration, restlessness, and irritability.
Question 2
A patient is being evaluated for symptoms including paranoia, auditory hallucinations, and
tangential thoughts. Which of the following conditions is most consistent with this presentation?
A) Post-Traumatic Stress Disorder (PTSD)
B) Bipolar I Disorder
C) Schizophrenia
D) Generalized Anxiety Disorder (GAD)
E) Major Depressive Disorder
Correct Answer: C) Schizophrenia
Rationale: The core symptoms of schizophrenia include "positive symptoms" such as
delusions, hallucinations (usually auditory), and paranoia, as well as "disorganized
symptoms" like tangential thoughts, suspiciousness, and disorganized behavior.
Question 3
A 5-year-old child presents with severe ear pain (otalgia), muffled hearing, and a popping
sensation in the ear. The parent notes the child recently recovered from a "bad cold." What is the
most likely diagnosis?
A) Otitis externa
B) Meniere’s disease
C) Acute otitis media
D) Mastoiditis
E) Peritonsillar abscess
Correct Answer: C) Acute otitis media
Rationale: Acute otitis media often follows a viral upper respiratory infection or an allergic
, 2
rhinitis flare-up. The infection causes fluid buildup in the middle ear, leading to the classic
symptoms of otalgia, muffled hearing, and popping or pressure sensations.
Question 4
Which of the following clinical findings is most characteristic of a peritonsillar abscess?
A) Barking cough and inspiratory stridor
B) White plaques on the tongue and oral mucosa
C) High-pitched cat-like cry
D) Severe sore throat and "hot potato" voice
E) Sudden onset of high fever and a "slapped-cheek" rash
Correct Answer: D) Severe sore throat and "hot potato" voice
Rationale: A peritonsillar abscess is a localized collection of pus behind the tonsils. It is
characterized by severe unilateral throat pain, difficulty swallowing (dysphagia), jaw
muscle spasms (trismus), and a muffled, "hot potato" voice due to the swelling in the
oropharynx.
Question 5
An autoimmune condition characterized by "diffuse toxic goiter" is the most common cause of
hyperthyroidism. This condition is known as:
A) Hashimoto's thyroiditis
B) Cushing's disease
C) Addison's disease
D) Graves' disease
E) Pheochromocytoma
Correct Answer: D) Graves' disease
Rationale: Graves' disease is an autoimmune disorder where thyroid-stimulating
immunoglobulins (TSI) bind to TSH receptors, causing the thyroid to overproduce
hormones and enlarge (goiter). It is the leading cause of hyperthyroidism across most age
groups.
Question 6
A clinician is reviewing laboratory results for a patient with metabolic syndrome. Which of the
following findings is most strongly associated with increasing insulin resistance?
A) Serum Sodium < 135 mEq/L
B) LDL cholesterol < 100 mg/dL
C) Triglycerides > 150 mg/dL
D) Hemoglobin > 16 g/dL
E) Serum Potassium > 5.0 mEq/L
Correct Answer: C) Triglycerides > 150 mg/dL
Rationale: Elevated triglycerides (hypertriglyceridemia) are a key component of metabolic
