NR 507 Final Exam
Question Question : What term is used to describe a hernial protrusion of a saclike cyst
1. that contains meninges, spinal fluid, and a portion of the spinal
cord through a defect in a posterior arch of a vertebra?
Encephalocele
Meningocele
Spina bifida occulta
Myelomeningocele
Explanation: Myelomeningocele is a hernial protrusion of a saclike cyst containing
meninges, spinal fluid, and a portion of the spinal cord with its nerves
through a defect in the posterior arch of a vertebra. The remaining options
are not appropriate terms to identity the described condition.
Question 2. Question : What provides the best estimate of the functioning of renal tissue?
Glomerular filtration rate
, Hourly urine output
Serum blood urea nitrogen and creatinine
The specific gravity of the solute concentration of the urine
Explanation: The glomerular filtration rate provides the best estimate of the level of
functioning of renal tissue. The other options are not used to assess renal
tissue function.
Question 3. Question : Where are Langerhans cells found?
Skin
Intestinal lining
Kidney
Thyroid
Explanation: Of the available options, only the skin is the location for Langerhans
cells.
,Question 4. Question : Where in the lung does gas exchange occur?
Trachea
Segmental bronchi
Alveolocapillary membrane
Main bronchus
Explanation: Gas exchange occurs only across the alveolocapillary membrane.
Question 5. Question : The tonic neck reflex observed in a newborn should no longer be
obtainable by:
2 years
1 year
, 10 months
5 months
Explanation: The tonic neck reflex should be unobtainable by 5 months of age.
Question 6. Question : When renin is released, it is capable of which action?
Inactivation of autoregulation
Direct activation of angiotensin II
Direct release of antidiuretic hormone (ADH)
Formation of angiotensin I
Explanation: When renin is released, it cleaves an -globulin (angiotensinogen
produced by liver hepatocytes) in the plasma to form angiotensin I.
