Question 1
One worker in the surgical center is found to be culture positive for Streptococcus
microorganisms in his nasal mucosa but has no symptoms of infection. What is this person's
status in the chain of infection?
A) Portal of entry
B) Susceptible host
C) Portal of exit
D) Reservoir
This worker is not considered a susceptible host even though he is harboring a pathogenic
microorganism because the microorganism has not proliferated to the point of making him sick
with an active infection. Thus he is an asymptomatic carrier who is capable of infecting other
people who are more susceptible to this microorganism.
Question 2
The client with an in-dwelling urinary catheter requires a urine specimen for culture and
sensitivity. Which technique should you use to obtain the specimen?
A) Wipe the distal end of the catheter with an alcohol sponge. Separate the distal end of the
catheter from the drainage collection tube and allow 5 to 10 mL of fresh urine to drain
into a sterile container.
B) Empty the residual urine in the collection bag completely and discard. Collect the urine
that drains into the bag during the next hour.
C) Clamp the catheter close to the distal end for 15 minutes. Cleanse the aspiration site on
the catheter with iodine. Draw up a 2-mL specimen with a sterile needle and syringe.
D) Clamp the catheter close to the distal end for 2 hours. Have the client void around the
catheter into a sterile specimen container.
Urine from the collection bag is considered contaminated. The catheter and drainage system unit
should not be separated. The client should never attempt to void around the catheter.

Question 3
Which statement regarding platelet function in hemostasis is true?
A) Platelets are required for erythrocyte aggregation.
B) Platelet aggregation helps maintain blood vessel integrity during tissue trauma.
C) Platelet aggregation prevents the extension of clot formation beyond the area of injury.
D) Platelet aggregation is dependent on adequate amounts of all clotting factors.
Aggregation of platelets stimulates the initiation of the blood clotting cascade and adds to
blood vessel integrity by forming a large, semisolid plug within the lumen and walls of blood
vessels, thereby disrupting blood flow.
Question 4
The nurse is providing care for a client in a sickle cell crisis who has effective pain
management. Which of the following is the priority nursing diagnosis at this point in the
client’s care?
A) Deficient Knowledge related to prevention of crisis episodes
B) Risk for Infection related to decreased spleen function
C) Risk for Injury related to decreased tissue oxygenation
D) Deficient Knowledge related to contraception and pregnancy options
During crisis when cells are sickled, blood flow is obstructed in the microcirculation and
macrocirculation. Depending on which tissue is hypoxic or anoxic, ischemia can lead to tissue
injury and cell death.
Question 5
Drug idiosyncrasy: An unexpected drug reaction.
Extravasation: This is a complication from infusing a vesicant fluid.
Thrombocytopenia: This is a side effect of antineoplastics that may result in increased bleeding.
Drug tolerance: This is a decreased response to a drug that may require an increased dose.
Miosis: A reaction of the eye to an narcotic agonist.
