A mаn is brоught tо the emergency depаrtment аfter he fell while wоrking at a construction site. He has multiple abrasions all over his body, a right ankle fracture and a right shoulder dislocation. He is told by the physician that he will need to be off work for 8 weeks. The patient expresses anger and frustration at the possibility of loss of income and inability to care for his wife who is ill. A finding related to the General adaptation syndrome (GAS) that the nurse would expect to find on assessment of the patient is:

Cаrnоsine (shоwn belоw) is а dipeptide molecule mаde up of the amino acids β-alanine and histidine bound together through an amide bond. It is highly concentrated in muscle and brain tissues and has been proven to scavenge reactive oxygen species, among other things. Consider the different conformations of carnosine through the C2-C3 bond and answer the following questions. Which of the Newman structures below represents the conformation wherein the dihedral angle between the “Im” group and the “NH(β-Ala)” group is 180°? [180deg] Which of the Newman structures below represents the conformation wherein the dihedral angle between the “Im” group and the “NH(β-Ala)” group is 0°? [0deg] Which Newman structure of carnosine (through the C2-C3 bond) shown below shows the molecule in its lowest energy conformation (assume “NH(β-Ala)” is larger than CO2H)? [lowestE] Which Newman structure of carnosine (through the C2-C3 bond) shown below shows the molecule in its highest energy conformation (assume “NH(β-Ala)” is larger than CO2H)? [highestE] What is the relationship between structures B and E below? [relationship]
