20-Year-Old-Male with Abdominal Trauma
Richard Watkins, 20, fell off his roof while replacing some shingles. Upon arrival at the scene, paramedics make the following observations:
•Abdominal pain, right upper quadrant
•Cyanotic, cool & clammy skin
•Falling blood pressure, 100/60 mm Hg; rapid pulse, 100 beats/min
Paramedics start an IV to rapidly infuse a 0.9% sodium chloride solution (normal saline). They transport him to a small rural hospital where Mr. Watkins’s blood pressure continues to fall and his cyanosis worsens. The local physician begins infusing O negative packed red blood cells (PRBCs) and arranges transport by helicopter to a trauma center. She sends additional PRBC units in the helicopter for transfusion en route. After arrival at the trauma center, the following notes were added to Mr. Watkins's chart:
•Abdomen firm and distended
•Blood drawn for typing and cross matching: packed A positive blood cells infused
•Emergency FAST (focused assessment with sonography for trauma) ultrasound is positive for intraperitoneal fluid
A positive FAST scan indicates intra-abdominal bleeding. Mr. Watkins's condition continues to deteriorate, so he is prepared for surgery. The operation reveals a lacerated liver, which is repaired. Mr. Watkins’s vital signs stabilize.
2. NCLEX-STYLE Why was Mr. Watkins given PRBCs in addition to normal saline solution? What problem does the infusion of PRBCs address that the saline solution could not?
a. PRBCs help restore blood ion composition to normal.
b. PRBCs increase blood osmotic pressure, making the infused fluid stay in the vessels rather than move into the cells.
c. PRBCs enhance clotting, sealing off the injured vessels.
d. PRBCs contain hemoglobin, so they are able to carry oxygen to the tissues.

- Plekhg5 functions in bottle cell formation, and Shroom3 functions in neural plate closure, yet the phenotype of injecting mRNA of each into the animal pole of a fertilized egg is very similar. What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forwardWhat are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?arrow_forwardwhat did charles darwin do in sciencearrow_forward

First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids using the same colors as in #7. Do not color the bonds in the backbone of each amino acid. B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds in the backbone of each amino acid. C. Position the two amino acids on the page below in an orientation where the two R groups could bond together.
