Section 1: History Taking and Subjective Data
Questions 1-8
Question 1 Erin Bradley, a 25-year-old female, presents with complaints of fatigue, palpitations,
and unintentional weight loss over the past 3 months. Which additional question would be most
important to ask during the history of present illness using the OLDCARTS framework?
A. "Have you had any recent infections?" B. "Do you feel hot when others are comfortable?"
[CORRECT] C. "Have you traveled outside the country recently?" D. "What is your typical
daily diet?"
Correct Answer: B
Rationale: Heat intolerance is a cardinal symptom of hyperthyroidism, which should be high on
the differential given Erin's triad of fatigue, palpitations, and weight loss. This question directly
addresses the "A" (associated symptoms) in OLDCARTS and helps differentiate
hyperthyroidism from other causes such as diabetes, malignancy, or chronic infection. Recent
infections (A) might suggest subacute thyroiditis but are less specific. Travel history (C) is
relevant for infectious diseases but not the priority here. Dietary history (D) is important for
nutritional assessment but does not immediately advance the diagnostic reasoning for this
presentation. The clinical reasoning error in choosing A, C, or D involves pursuing less likely
etiologies before ruling in/out the most probable diagnosis based on the symptom cluster.
Question 2 When obtaining Erin's past medical history, which finding would be most relevant to
her current symptoms and potential differential diagnoses?
A. Childhood asthma treated with bronchodilators B. History of autoimmune disease
[CORRECT] C. Previous ankle fracture requiring ORIF D. Seasonal allergic rhinitis
,2
Correct Answer: B
Rationale: Autoimmune diseases such as Hashimoto's thyroiditis, Graves' disease, type 1
diabetes, or systemic lupus erythematosus often cluster due to shared genetic susceptibility. A
history of any autoimmune condition significantly increases the pre-test probability of
autoimmune thyroid disease. Childhood asthma (A) is unrelated to thyroid function. Previous
orthopedic trauma (C) has no bearing on endocrine function. Seasonal allergies (D), while
common, do not increase risk for thyroid dysfunction. The common reasoning error is dismissing
past medical history as irrelevant when, in fact, autoimmune history provides crucial diagnostic
probability information.
Question 3 Erin reports that her mother had "thyroid problems" and takes medication daily.
Which specific follow-up question is most important for determining Erin's risk assessment?
A. "Did your mother have diabetes as well?" B. "Do you know if your mother's thyroid was
overactive or underactive?" [CORRECT] C. "Was your mother treated with surgery or
radioactive iodine?" D. "At what age was your mother diagnosed?"
Correct Answer: B
Rationale: Determining whether the mother had hyperthyroidism (Graves' disease) or
hypothyroidism (Hashimoto's thyroiditis) is essential because both have genetic components,
though the clinical presentations differ significantly. Knowing the type helps guide which
diagnostic pathway to emphasize. While treatment type (C) and age of diagnosis (D) provide
some information, the nature of the disorder (B) is most critical for Erin's current presentation.
Diabetes (A) is less relevant unless suggesting autoimmune polyglandular syndrome. The
clinical reasoning error involves focusing on treatment details before understanding the disease
etiology—treatment choices do not change Erin's genetic risk, but disease type does influence
the differential.
Question 4 During the review of systems, Erin reports occasional palpitations described as "my
heart racing." Which additional cardiac symptom should the nurse practitioner prioritize asking
about to assess for potential life-threatening complications?
A. Chest pain, pressure, or tightness [CORRECT] B. Orthopnea requiring multiple pillows C.
Paroxysmal nocturnal dyspnea D. Peripheral edema in lower extremities
Correct Answer: A
Rationale: Palpitations accompanied by chest pain may indicate cardiac ischemia, significant
arrhythmia, or structural heart disease—potential complications of sustained hyperthyroidism. In
a 25-year-old with possible hyperthyroidism, excluding angina or significant arrhythmia is
, 3
essential before proceeding with outpatient management. Orthopnea (B), PND (C), and
peripheral edema (D) are classic signs of heart failure, which is less likely in this young patient
without known cardiac disease, though still important to assess in comprehensive ROS. The
clinical reasoning error involves assuming palpitations in a young patient are "just anxiety" or
"just hyperthyroidism" without ruling out concurrent cardiac pathology that requires immediate
intervention.
Question 5 Erin mentions she has been trying to conceive for the past 6 months without success.
Which aspect of her social history is most critical to explore further?
A. Occupational exposure to chemicals B. Sexual history and menstrual pattern changes
[CORRECT] C. Exercise routine and intensity D. Caffeine and alcohol consumption
Correct Answer: B
Rationale: Thyroid dysfunction, particularly hyperthyroidism, commonly causes menstrual
irregularities (oligomenorrhea or amenorrhea) and anovulation, leading to infertility. Detailed
menstrual history (frequency, duration, flow changes) and sexual history are essential to
differentiate thyroid-related infertility from other causes. While occupational exposures (A),
exercise (C), and substance use (D) can affect fertility, the temporal association with her other
symptoms makes thyroid-related menstrual dysfunction the most likely contributor. The clinical
reasoning error involves pursuing lifestyle factors before ruling out physiological causes clearly
linked to her presenting symptoms.
Question 6 When inquiring about Erin's medication history, which over-the-counter or
supplement use would be most important to identify?
A. Daily multivitamin with iron B. Biotin supplements for hair and nails [CORRECT] C.
Calcium carbonate for heartburn D. Vitamin D supplementation
Correct Answer: B
Rationale: Biotin (vitamin B7) supplements can cause falsely low TSH and falsely elevated
T4/T3 on immunoassay-based thyroid function tests, leading to misdiagnosis of hyperthyroidism.
The FDA issued warnings about biotin interference with laboratory tests. Patients often do not
disclose "vitamins" as medications, so specific inquiry is necessary. Iron (A), calcium (C), and
vitamin D (D) do not interfere with thyroid function testing. The clinical reasoning error involves
accepting laboratory values at face value without considering pre-analytical factors that could
lead to misdiagnosis and inappropriate treatment.
