. A nurse practitioner employed in the emergency department admits a patient who has experienced severe frostbite to his hands and toes after becoming lost on a ski trail. The NP recognizes that which of the following phenomena has caused the tissue damage? (Points : 3)Decreased blood viscosity has resulted in interstitial bleeding.Reactive vasodilation has compromised perfusion.Autonomic nervous stimulation has resulted in injury.Decreased blood flow has induced hypoxia.Question 21.21. A nurse practitioner employed in a hospitalist notices that a patient is experiencing muscle atrophy following 2 weeks in traction after a motor vehicle accident. Which of the following factors has most likely contributed to the atrophy of the patient’s muscle cells? (Points : 3)High levels of insulin and IGF-1 in the patient’s blood during immobilizationDenervation of the affected muscles during the time of tractionA reduction of skeletal muscle use secondary to the traction treatmentReduced oxygen consumption and cellular function that ensures muscle cell survivalQuestion 22.22. An infant who is four days postpartum has been diagnosed with a single-gene disorder.

Which of the following teaching points most accurately captures an aspect of single-gene congenital disorders? (Points : 3)Affected genes are present on autosomal chromosomes rather than sex chromosomes.The majority of single-gene disorders manifest near the time of puberty.A particular defect can be caused by mutations at one of several different loci.Single-gene disorders are associated with existing rather than new mutations.Question 23.23.

(Points : 3)The gene fragment responsible for insulin production can be isolated and reproduced.Particular bacteria are capable of insulin production.It is possible to reproduce the chromosome responsible for insulin production.Recombination of DNA base pairs can result in a gene that will produce insulin.Question 24.24.
