The result of his skin turgor test indicates late signs of dehydration (patient had skin with poor turgor)‚ and the presence of tenting in the skin indicates the severity of his dehydration. Patient Case Question 5: Are the negative Grey Turner and Cullen signs evidence of a good or poor prognosis? A positive test for

What type of proteins in the cells membrane was involved in the homeostatic imbalance of the heart cells? Proteins rise then fall. Channels open allowing an inward flow of sodium ions changing electrochemical gradient‚ causing a rise in membrane potential. Causing more channels to open‚ then causing a bigger electric current

Effects of Eating Disorders Eating disorders are serious medical illnesses. They often go along with other problems such as stress‚ anxiety‚ depression‚ and substance use. Eating disorders can lead to the development of serious physical health problems‚ such as heart conditions or kidney failure. Someone whose body weight is at least 15% less than the average weight for that person’s height may not have enough body fat to keep organs and other body parts healthy. In severe cases‚ eating disorders

would guess a fluid volume deficit. Dark amber urine‚ dry mucus membranes‚ poor skin turgor‚ and labs all point in that direction. Although the patient’s output seems to be adequate‚ everything else points towards dehydration. It also seems like the patient has a fluid/electrolyte imbalance which may be putting the water in the wrong departments‚ or an infection (as reflected in pt. vital signs). So even though he is receiving IV fluids‚ it’s not reflecting on his physical assessment and labs. 2.)

Morning sickness usually does not cause dehydration or nutrition imbalance and is seen all throughout the pregnancy‚ where as hypermesis is only seen between the 4th and 10th week of pregnancy.
