Question 1
A 62-year-old male with a history of chronic stable angina is being counseled
on the proper utilization and storage of sublingual nitroglycerin (NTG) tablets.
Which statement by the patient demonstrates an accurate understanding of the
,stability and maintenance of this medication?
A. "I should transfer a few pills to a plastic keychain container so I always have
them on hand."
B. "Once the bottle is opened, I can safely use the pills until the expiration date
printed on the label."
C. "I must keep the tablets in their original dark glass bottle and replace them
six months after opening."
D. "Storing the bottle in the bathroom medicine cabinet will keep it safe from
temperature extremes."
ANSWER: C. "I must keep the tablets in their original dark glass bottle and
replace them six months after opening."
EXPLANATION: Sublingual nitroglycerin is highly unstable and chemically
volatile. It readily degrades when exposed to air, moisture, light, and heat. To
preserve potency, it must remain in its original light-resistant amber glass
bottle with a tightly sealed cap. Once the original seal is broken and the bottle
is opened, the medication loses its efficacy rapidly; therefore, patients must
discard and replace the bottle exactly six months after opening, regardless of
the manufacturer’s expiration date printed on the packaging. Plastic
containers absorb the drug, and humid environments like bathroom cabinets
accelerate degradation.
Question 2
A nurse practitioner is evaluating laboratory results for a 34-year-old female
presenting with profound fatigue, pallor, and microcytic, hypochromic red
blood cells. The iron panel reveals a low serum iron level, a markedly elevated
,Total Iron-Binding Capacity (TIBC), and a serum ferritin level of 8 ng/mL.
Which condition is most consistently supported by these objective findings?
A. Thalassemia minor
B. Iron deficiency anemia
C. Anemia of chronic disease
D. Sideroblastic anemia
ANSWER: B. Iron deficiency anemia
EXPLANATION: Serum ferritin is the most sensitive and specific biomarker
for evaluating total body iron stores. A ferritin level below 15 ng/mL is
diagnostic of iron deficiency anemia (IDA). In IDA, the body lacks sufficient
iron to synthesize hemoglobin, leading to microcytic and hypochromic
indices. To compensate for depleted iron reserves, the liver increases the
production of transferrin, which directly causes a high Total Iron-Binding
Capacity (TIBC). Thalassemia presents with normal to high ferritin and
TIBC; anemia of chronic disease presents with normal to high ferritin and
low TIBC.
Question 3
During a routine wellness assessment of a 47-year-old male, the advanced
practice provider performs an abdominal examination. To ensure clinical
accuracy and prevent the artificial alteration or stimulation of peristaltic
motility, which sequential order of physical assessment techniques must be
strictly followed?
A. Inspection, Palpation, Percussion, Auscultation
B. Inspection, Auscultation, Percussion, Palpation
, C. Auscultation, Inspection, Percussion, Palpation
D. Inspection, Percussion, Palpation, Auscultation
ANSWER: B. Inspection, Auscultation, Percussion, Palpation
EXPLANATION: The standard, universally accepted sequence for an
abdominal physical examination is inspection followed immediately by
auscultation, then percussion, and finally palpation. Performing percussion
or palpation beforehand exerts mechanical pressure on the abdominal viscera
and the smooth muscle walls of the gastrointestinal tract. This physical
manipulation artificially stimulates peristalsis, alters the frequency and
character of baseline bowel sounds, and can skew diagnostic reasoning.
Question 4
A 24-year-old male presents to the primary care clinic with acute-onset right
lower quadrant (RLQ) abdominal pain, a low-grade fever, and nausea. While
performing the physical examination, the nurse practitioner applies deep, steady
pressure to the left lower quadrant (LLQ) of the abdomen and then abruptly
releases it. The patient immediately reports sharp, severe pain localized in the
right lower quadrant. Which eponymous clinical sign is positive?
A. Murphy's sign
B. Psoas sign
C. Obturator sign
D. Rovsing's sign
ANSWER: D. Rovsing's sign
EXPLANATION: Rovsing's sign is an indicative marker of localized
peritoneal irritation, classically associated with acute appendicitis. It is
