Proper order of techniques for abdominal assessment is - 1)inspection, 2) auscultation, 3) percussion, and 4) palpation. Abdominal assessment - performed in this order as percussion and palpation can increase peristalsis, which can give a false interpretation of bowel sounds. tympanic sounds are heard over - hollow organs such as the stomach and intestines while dull notes are heard - over solid organs such as the liver, kidneys and a full bladder.

Mastering Genetics 3,4,9,10,11 What is the basis for homology among chromosomes? - ANSWER- type and location of genes Polydactyly is expressed when an individual has extra fingers and/or toes. Assume that a man with six fingers on each hand and six toes on each foot marries a woman with a normal number of digits. Having extra digits is caused by a dominant allele. The couple has a son with normal hands and feet, but the couple's second child has extra digits. What is the probability that ...
