NUR 555- Quiz 9: Questions With Correct Solutions, Already Passed-SNHU

Question 1 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 The functional kidney is associated with which embryonic organ? Select one. Question options: 1.2 / 1.2 points 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 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 1.2 / 1.2 points 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 / 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. Question 5 1.2 / 1.2 points Compared with other renal disorders, a child diagnosed with nephritic syndrome is more susceptible to what health risk? Select one. Question options: Frothy urine Pallor Edema Bacterial peritonitis Hide question 5 feedback Feedback Children with nephrotic syndrome are more susceptible to infections such as cellulitis, spontaneous bacterial peritonitis, and bacteremia. This occurs partially as a result of the urinary losses of immunoglobulin G, which causes hypoglobulinemia. The remaining options are all commonly seen among those experiencing renal disorders. Question 6 1.2 / 1.2 points What unique factor causes adolescent girls to have a high risk for sexually transmitted infections (STIs)? Select one. Question options: They are in an experimental phase and believe they are resistant to developing STIs. The position of susceptible cells on the adolescent cervix is different than in older women. The length of the vaginal canal is short in adolescents In adolescent girls, the anus to the vaginal introitus is in close proximity. Hide question 6 feedback Feedback The unique factor for adolescent women is that they have a physiologically increased susceptibility to infection because of the position of susceptible cells on the surface of the cervix. The remaining options are not considered legitimate risk factors for STIs. Question 7 An 85-year-old person has been diagnosed with a urinary tract infection. What clinical manifestation does the healthcare professional expect to see in this person? Select one. Question options: Confusion and malaise Dysuria, frequency, and suprapubic pain Hematuria and flank pain Pyuria, urgency, and frequency Hide question 7 feedback
