Question

question 18 (1 point) save
to maintain gut integrity, if a client with pancreatitis will eat nothing by mouth (npo) for longer than 7 days:
tube feeding with a polymeric formula should be considered
tube feeding with an elemental formula should be considered
peripheral parenteral nutrition should be considered
both tube feeding and central parenteral nutrition should be considered
question 19 (1 point) save
cystic fibrosis is caused by
a genetic defect.
cigarette smoking.
bacterial infection.
inadequate folate intake.
question 20 (1 point) save
phenylketonuria is caused by
excessive intake of phenylalanine.
failure to break down excess phenylalanine.
inadequate intake of phenylalanine during pregnancy.
inability to digest proteins that contain phenylalanine.

Explanation:

• For Question 18: In pancreatitis patients with NPO for over 7 days, elemental formula tube - feeding helps maintain gut integrity as it is easily absorbed without much pancreatic stimulation.
• For Question 19: Cystic fibrosis is an autosomal - recessive genetic disorder caused by mutations in the CFTR gene.
• For Question 20: Phenylketonuria (PKU) is due to a deficiency in the enzyme phenylalanine hydroxylase, leading to the failure to break down excess phenylalanine.

Answer:

Question 18: Tube feeding with an elemental formula should be considered
Question 19: a genetic defect.
Question 20: failure to break down excess phenylalanine
