Question 1 1..2 points
A child is diagnosed with Duchenne muscular dystrophy, and the parents want to know how this
occurred. Which statement by the healthcare professional is most accurate? Select one.
Question options:
X-linked recessive inheritance
Common SMN1 gene abnormality
Autosomal dominant inheritance
Inheritance is not well defined
Hide question 1 feedback
Feedback
A deletion of a segment of DNA or a single-gene defect on the short arm of the X chromosome is believed to be the cause of the X-linked
inherited type of Duchenne muscular dystrophy. Spinal muscular atrophy is a common recessive genetic disorder due to an abnormality in
the SMN1 gene. Facioscapulohumeral muscular dystrophy is a mild progressive type of muscular dystrophy that is inherited in an autosomal
dominant pattern. Limb girdle muscular dystrophy may be a recessive disorder but is not well defined.
Question 2 1..2 points
The functional kidney is associated with which embryonic organ? Select one.
Question options:
Metanephros
Mesonephros
Pronephros
Endonephros
Hide question 2 feedback
Feedback
The functional kidney is associated with the metanephros. The kidney develops from three sets of structures: the pronephros (nonfunctional
by the end of the embryonic period), mesonephros (nonfunctional), and metanephros (the functional kidney). Endonephros is not relevant to
, this process.
Question 3 1..2 points
Hypercalciuria is primarily attributable to which alteration? Select one.
Question options:
Defective renal calcium reabsorption
Intestinal hyperabsorption of dietary calcium
Bone demineralization caused by prolonged immobilization
Hyperparathyroidism
Hide question 3 feedback
Feedback
Hypercalciuria is usually attributable to intestinal hyperabsorption of dietary calcium and less commonly to a defect in renal calcium
reabsorption. Hyperparathyroidism and bone demineralization associated with prolonged immobilization are also known to cause
hypercalciuria but to a much lesser degree.
Question 4 1..2 points
Acute glomerulonephritis (AGN) may be accompanied by a positive throat or skin culture for which
bacteria? Select one.
Question options:
Staphylococcus aureus
Streptococcus
Pseudomonas aeruginosa
Haemophilus
Hide question 4 feedback
Feedback
AGN may be accompanied by a positive throat or skin culture for Streptococcus. AGN is not associated with any of the other organisms.
