1. If a patient presents with a WBC count of 450 cells/L, what immediate clinical
considerations should be taken into account?
Increased risk of infections
Enhanced healing capacity
Normal immune function
Decreased blood pressure
2. What is Paronychia?
where the nail flakes away
A viral disorder of the Nail
the seal at the side of the nail wall
Bacterial inflammation of the skin surrounding the nail plate
3. Describe the mechanism by which a positive Nickolsky sign occurs and its
implications for skin health.
A positive Nickolsky sign occurs when the skin is dry and flaky due to
dehydration.
A positive Nickolsky sign occurs when the outer layer of skin
separates easily from the underlying layers due to a loss of
adhesion, indicating a potential skin disorder.
A positive Nickolsky sign occurs when the skin becomes inflamed and
red due to an allergic reaction.
A positive Nickolsky sign occurs when the skin shows signs of
infection with pus formation.
,4. A hematocrit is a measure of:
Total red blood cell mass
Total red blood cells
Packed red blood cell volume
Red blood cell sedimentation rate
5. Which examination assesses corneal sensitivity?
Touching some cotton onto the cornea, and observing for the
expected blink response
Looking for a portion of the iris to not light up when a light is shined
on the limbus
Asking the patient to read a chart 20 feet away
Looking for adequate lateral movements of both pupils
6. What is Seborrheic keratosis?
An infection of the skin by lice
A skin condition that can cause rough, scaly skin on the scalp, face
and upper body
A benign epidermal tumor "senile warts"
A disease that features a virus that resides in the ganglia of the
cerebrum or posterior spinal nerve roots
7. The primary function of hemoglobin is to
store iron.
give RBCs their color.
, carry oxygen to peripheral tissues.
transport glucose.
8. If a healthcare provider observes widespread eyes and a thin upper lip in a
child, what should be the next step in their assessment?
Ignore the features as they are not significant.
Refer the child to a plastic surgeon.
Immediately diagnose fetal alcohol syndrome.
Conduct a comprehensive developmental evaluation.
9. If a patient exhibits a diminished blink response during the wisp test, what
clinical implications might this have for their ocular health?
It suggests the patient has perfect vision.
It may indicate corneal damage or neuropathy.
It means the patient is experiencing eye strain.
It indicates the presence of cataracts.
10. Describe the significance of CFU in assessing bacterial populations in a
sample.
CFU measures the total mass of bacteria in a sample.
CFU quantifies the genetic material of bacteria in a sample.
CFU estimates the number of viable bacteria in a sample, indicating
the level of contamination or infection.
CFU identifies the specific species of bacteria present in a sample.
11. Describe how glucose levels can influence the specific gravity of urine.
, High glucose levels can increase urine specific gravity due to
increased solute concentration.
Glucose levels have no effect on urine specific gravity.
Low glucose levels decrease urine specific gravity.
Glucose levels only affect urine pH, not specific gravity.
12. Describe the significance of elevated urobilinogen levels in a urine dip test
in relation to liver function.
Elevated urobilinogen levels indicate kidney disease.
Elevated urobilinogen levels are unrelated to liver health.
Elevated urobilinogen levels suggest normal liver function.
Elevated urobilinogen levels may indicate liver dysfunction or
hemolysis.
13. Describe the significance of conducting a culture and sensitivity test before
starting antibiotic therapy.
It helps to identify the most effective antibiotic for treating the
specific bacterial infection.
It assesses the patient's overall health status.
It eliminates the need for further testing of the infection.
It provides immediate results for antibiotic selection.
14. You are concerned for a friend who went camping in the CA mountains, and
was bitten by several ticks of the sort shown in the image, below. Your friend
has since developed a "bullseye" rash.
What is the name of the pathogen and of the disease that your friend may
