Why is a measure of serum lactate obtained in the initial assessment of the trauma patient? Answer: c - a) to measure oxygenation and ventilation b) to quantify the base deficit for the adequacy of cellular perfusion c) *to gauge end-organ perfusion and tissue hypoxia ** d) to determine the underlying cause of shock A trauma patient is restless and repeatedly asking "where am I?" vital signs upon arrival were BP 100/60 mm Hg, HR 96 beats/min, and RR 24 breaths/min. Her skin is cool and...

What is the basic structure of an amino acid? What do they look like? -Answer- amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group How do you identify the 3 different types of side chains: non-polar/hydrophobic, polar, and charged? -Answer- Non-polar/hydrophobic - end with CH or "can't have" water. Polar - end with OH, SH, or NH. Charged - end with a charge what kinds of bonds do each of the 3 different types of side chains make? -Answerionic, hy...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - Answer Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amino acid valine, leads to the development of sick...
