New red blood cells are made by the bone marrow and transport oxygen and carbon
dioxide.
What is the life span of a red blood cell?
A. 30 days.
B. 60 days.
C. 90 days.
D. 120 days

, D: The typical life span of a red blood cell is 120 days. Red blood cells contain
hemoglobin,
which carries oxygen to cells and carbon dioxide back to the lungs.
Depressed or inverted T-waves on ECG analysis can occur with many different clinical
situations in pediatric patients. Which of the following is NOT a common reason for
depressed
or inverted T-waves?
A. Hypokalemia.
B. Myocarditis.
C. Digitalis toxicity.
D. Hyperthyroidism.
Give this one a try later!
B: Hyperthyroidism commonly causes an increase in T-wave amplitude, not a
decrease.
Myocarditis, hypokalemia, and digitalis toxicity are common reasons for
inverted or decreased Twaves.
A newborn with jaundice is treated with outpatient ultraviolet light therapy. What blood
test is
tested to ensure that the jaundice is clearing?
A. Bilirubin.
B. CBC.
C. AST.
D. Amylase.
Give this one a try later!
, A: Jaundice is caused by an elevation of bilirubin, which is monitored to
ensure treatment
success. As red blood cells break down, bilirubin forms and is excreted
through the liver, but the
infant's liver may be immature and unable to remove bilirubin fast enough, so
bilirubin levels in the
blood rise. Ultraviolet light helps to break down bilirubin.
The child of a celebrity client is admitted to a nursing floor, and the nurse taking care of
this
patient notices a medical assistant not involved in the care of the patient looking at her
chart.
What would be the most appropriate course of action?
A. Confront medical assistant and make her apologize.
B. Notify nursing supervisor of HIPAA violation.
C. Place chart in locked cabinet.
D. Place chart at end of client's bed.
Give this one a try later!
B: An unauthorized person's looking at any patient's chart is a clear HIPAA
violation and
must be reported to the supervisor in charge so that appropriate disciplinary
action can be taken.
What is the leading cause of death in children in developing countries?
A. Accidental trauma.
B. TB.
C. AIDS.
D. Infectious diarrhea.
, Give this one a try later!
D: Infectious diarrhea remains the leading cause of death in developing
countries.
Outbreaks of diarrhea are common in areas with poor sanitation that allows
food and water to
become contaminated with bacteria, such as E. coli or Shigella.
14-year-old male with renal failure is given an arteriovenous fistula (shunt) for future
dialysis.
How does the nurse assess the shunt post-operatively for patency?
A. Assess for bruit and thrill.
B. Monitor blood pressure on that arm.
C. Ease of venipuncture at shunt site.
D. Rate of flow during dialysis.
Give this one a try later!
A: The patency of an AV shunt is assured by assessing for bruit and thrill.
Continuous wave
Doppler ultrasound can also assess patency. Venipuncture and blood
pressure measurements
should never be done on the arm with an AV shunt.
A 5-year-old girl has a fever, headache, and complaints of a stiff neck. The physician
suspects
bacterial meningitis. What is the best test culture site to detect the bacteria?
A. Lumbar puncture.
B. Clean catch urine.
C. Blood culture.
D. Nasal swab.
