Question 1
A 24-year-old female presents to the clinic with severe, generalized pruritus that is
worse at night. Upon physical examination, you note linear burrows in the web spaces
of her fingers, on her wrists, and around her axillae. Which of the following is the most
appropriate first-line pharmacological treatment?
A. Topical Hydrocortisone 1% cream
B. Oral Diphenhydramine 25mg
C. Topical Permethrin 5% cream
D. Oral Amoxicillin 500mg
Answer: C. Topical Permethrin 5% cream
Rationale: The clinical presentation of severe nocturnal pruritus with linear burrows in
the interdigital web spaces and flexor surfaces is classic for scabies. Topical Permethrin
5% cream is the first-line treatment of choice for scabies infestation. It must be applied
from the neck down to the toes, left on for 8 to 14 hours, and then thoroughly washed
off. Hydrocortisone and diphenhydramine only address symptoms but do not eliminate
the mite, while antibiotics like amoxicillin are ineffective unless a secondary bacterial
infection is present.
, Question 2
A family nurse practitioner is evaluating a screening test for a local health clinic. The
test is highly sensitive. Which of the following statements best describes a screening
test with high sensitivity?
A. The test is excellent at correctly identifying individuals who do not have the disease.
B. The test has a high rate of true negative results.
C. The test is excellent at correctly identifying individuals who actually have the disease.
D. The test is used exclusively for establishing a definitive diagnosis.
Answer: C. The test is excellent at correctly identifying individuals who actually
have the disease.
Rationale: Sensitivity refers to the probability that a screening test will be positive when
the disease is truly present (true positive rate). A highly sensitive test is ideal for
screening because it minimizes false negatives, ensuring that fewer cases of the
disease are missed. Conversely, specificity refers to the test's ability to correctly identify
those without the disease (true negative rate).
Question 3
A 19-year-old patient returns to the clinic for a follow-up on moderate acne vulgaris. The
clinician decides to prescribe a topical retinoid. Which of the following instructions
should be included in the patient education?
A. Apply the medication immediately after washing your face while the skin is damp.
B. Wash your face gently twice daily and wait 30 minutes before applying the
medication.
C. Apply a thick layer of the medication directly over open sores or sunburned skin.
D. Use the medication every 4 hours throughout the day for faster results.
Answer: B. Wash your face gently twice daily and wait 30 minutes before applying
the medication.
1. A patient presents with a dynamic, transient, erythematous, and intensely pruritic rash
that changes location within 24 hours. What is the primary management goal for this
condition?
A) Initiate high-dose oral corticosteroids immediately.
B) Identify and eliminate the triggering allergen or cause.
C) Apply topical tazarotene cream twice daily.
D) Perform an emergency punch biopsy of the lesion.
Answer: B) Identify and eliminate the triggering allergen or cause.
, Rationale: The patient is presenting with acute urticaria (hives), which is characterized
by transient wheals. The primary management strategy is to identify and eliminate the
underlying trigger (e.g., foods, medications, physical stimuli) while managing symptoms
with antihistamines.
2. Which of the following counseling points is most accurate when educating a patient
starting a topical retinoid for acne vulgaris?
A) Wash the face with an abrasive scrub right before applying the medication.
B) Apply the medication to wet skin immediately after washing to increase absorption.
C) Wait at least 30 minutes after washing the face before applying the medication.
D) Use the medication only on active lesions and avoid surrounding clear skin.
Answer: C) Wait at least 30 minutes after washing the face before applying the
medication.
Rationale: Applying topical retinoids to damp skin increases absorption and significantly
increases skin irritation, burning, and erythema. Patients should wait 20 to 30 minutes
until the skin is completely dry before application.
3. A 24-year-old female presents with severe nocturnal pruritus. On examination, you note
linear burrows and small papules in the finger webs, wrists, and periumbilical area.
What is the first-line treatment?
A) Topical Hydrocortisone 1% cream
B) Oral Fluconazole 150 mg single dose
C) Topical Permethrin 5% cream
D) Oral Amoxicillin 500 mg three times daily
Answer: C) Topical Permethrin 5% cream
Rationale: The presentation is classic for Scabies. Permethrin 5% cream is the first-line
topical treatment, applied from the neck down to the toes, left on for 8–14 hours, and
then washed off.
4. In a clinical trial evaluating a new diagnostic test for viral pharyngitis, the test correctly
identifies 95% of patients who actually have the disease. This characteristic refers to the
test's:
A) Specificity
B) Positive Predictive Value
C) Sensitivity
D) Negative Predictive Value
Answer: C) Sensitivity
Rationale: Sensitivity is the probability that a diagnostic test will be positive when the
disease is truly present (true positive rate). Specificity, on the other hand, is the ability to
correctly identify those without the disease.
5. According to current USPSTF guidelines, routine screening for colorectal cancer in
average-risk individuals should begin at what age?
A) 40 years old
B) 45 years old
, C) 50 years old
D) 55 years old
Answer: B) 45 years old
Rationale: The United States Preventive Services Task Force (USPSTF) lowered the
recommended age to start routine colorectal cancer screening from 50 to 45 years for
adults at average risk to address rising rates among younger populations.
6. When writing a clinical note using the SOAP format, where should the primary care
nurse practitioner document the formal differential diagnoses and final diagnosis?
A) Subjective (S)
B) Objective (O)
C) Assessment (A)
D) Plan (P)
Answer: C) Assessment (A)
Rationale: The Assessment section of a SOAP note contains the clinician's diagnostic
reasoning, differential diagnoses, and the final definitive or working diagnosis based on
the subjective and objective data collected.
7. A patient presents with localized abdominal pain in the left lower quadrant, fever, and
leukocytosis. Which diagnostic condition should be at the top of your differential list?
A) Acute Appendicitis
B) Acute Diverticulitis
C) Cholecystitis
D) Peptic Ulcer Disease
Answer: B) Acute Diverticulitis
Rationale: Left lower quadrant abdominal pain accompanied by fever and signs of
infection/inflammation (leukocytosis) is the classic presentation for acute diverticulitis in
Western populations.
8. What is the hallmark clinical finding that differentiates viral pharyngitis from Group A
Beta-Hemolytic Streptococcal (GABHS) pharyngitis?
A) Presence of a high fever
B) Presence of anterior cervical lymphadenopathy
C) Absence of cough and presence of tonsillar exudates
D) Presence of conjunctivitis, coryza, and cough
Answer: D) Presence of conjunctivitis, coryza, and cough
Rationale: The presence of viral symptoms such as cough, rhinorrhea/coryza,
hoarseness, and conjunctivitis strongly points away from Strep throat and indicates a
viral etiology.
9. A diagnostic test with high specificity is most useful to the clinician for which of the
following purposes?
A) Screening a large asymptomatic population
B) Ruling in a diagnosis when the test result is positive
C) Ruling out a diagnosis when the test result is negative
D) Reducing the overall cost of diagnostic workups
