Question 1
A 64-year-old male with a history of chronic hypertension and
hyperlipidemia presents to the emergency department with sudden onset
of severe, tearing chest pain radiating to his back. His blood pressure is
185/110 mmHg in the right arm and 160/95 mmHg in the left arm. A chest
X-ray reveals a widened mediastinum. Which of the following is the most
appropriate next step in management?
A. Intravenous administration of tissue plasminogen activator (tPA)
B. Immediate surgical consultation and initiation of intravenous beta-
blockers
,C. Sublingual nitroglycerin administration and urgent cardiac
catheterization
D. Emergent subcutaneous administration of low-molecular-weight
heparin
Answer: B. Immediate surgical consultation and initiation of
intravenous beta-blockers
Rationale: The clinical presentation of sudden, severe, tearing chest
pain radiating to the back, coupled with asymmetric blood pressures
in the upper extremities and a widened mediastinum on a chest X-
ray, is highly indicative of an acute aortic dissection. Management
requires immediate stabilization of the aortic wall by lowering blood
pressure and heart rate to decrease shear stress. Intravenous
beta-blockers (such as esmolol or labetalol) are the first-line
therapy to target a systolic blood pressure between 100-120 mmHg
and a heart rate below 60 bpm. Prompt surgical evaluation is
essential for type A dissections. Thrombolytics (tPA) and
anticoagulants are strictly contraindicated as they can lead to fatal
exsanguination. Nitroglycerin alone induces reflex tachycardia,
which increases aortic shear stress and worsens the dissection.
Question 2
A 45-year-old female presents to the clinic complaining of worsening
fatigue, weight gain, cold intolerance, and generalized muscle aches over
,the past four months. On physical examination, her thyroid gland is
diffusely enlarged, firm, and non-tender. Laboratory findings reveal an
elevated Thyroid-Stimulating Hormone (TSH) level and a decreased free
thyroxine (T4) level. Serum tests are strongly positive for anti-thyroid
peroxidase (anti-TPO) antibodies. Which of the following conditions is the
most likely diagnosis?
A. Graves' Disease
B. Subacute Granulomatous (de Quervain's) Thyroiditis
C. Hashimoto's Thyroiditis
D. Papillary Thyroid Carcinoma
Answer: C. Hashimoto's Thyroiditis
Rationale: Hashimoto's thyroiditis (chronic lymphocytic thyroiditis)
is the most common cause of hypothyroidism in iodine-sufficient
regions. It is characterized by autoimmune destruction of the
thyroid gland, typically presenting with symptoms of hypothyroidism
(fatigue, cold intolerance, weight gain) and a firm, non-tender goiter.
The presence of elevated TSH, low free T4, and positive anti-TPO
antibodies confirms the diagnosis. Graves' disease presents with
hyperthyroidism (weight loss, heat intolerance, tremors) and is
associated with TSH receptor antibodies. Subacute granulomatous
thyroiditis presents with a painfully tender thyroid gland following a
viral illness. Papillary thyroid carcinoma typically presents as a
discrete, painless thyroid nodule rather than a diffuse, symmetrical,
firm goiter.
, Question 3
A 28-year-old multigravida at 34 weeks gestation presents to the labor
and delivery unit with a sudden onset of painless, bright red vaginal
bleeding. She denies any trauma or recent intercourse. Vital signs are
stable, and the fetal heart rate tracing shows a reassuring Category I
pattern with a baseline of 140 bpm. Uterine contractions are absent.
Which of the following interventions is strictly contraindicated in the
initial assessment of this patient?
A. Transabdominal ultrasound examination
B. Continuous external fetal monitoring
C. Digital cervical examination
D. Placement of a large-bore intravenous catheter
Answer: C. Digital cervical examination
Rationale: Painless, bright red vaginal bleeding in the second or
third trimester is the classic presentation of placenta previa, where
the placenta implants over or near the internal cervical os.
Performing a digital cervical examination is strictly contraindicated
until the location of the placenta is confirmed by ultrasound. Digital
probing can inadvertently disrupt the placental attachment, leading
to catastrophic maternal hemorrhage and fetal distress. A
transabdominal ultrasound should be performed first to identify
placental position safely. Continuous fetal monitoring and large-bore
IV access are highly recommended components of initial
