You are a nurse on postpartum caring for a G6P4114 that is 4 hours postpartum after an emergent cesarean section (C/S). The patient delivered a viable infant male at 28 weeks gestation due to preeclampsia. She had been on magnesium sulfate for 23 hours prior to delivery and continues to be on magnesium sulfate. Her QBL (quantitative blood loss) in the C/S was 750mL.  Based on her vitals, what is your next action?  4 hours ago 2 hours ago  Now BP 130/90 120/80 105/75 HR 89 93 108 RR 14 14 14 SPo2 99% 98% 97% Temp 97.9F 98.2F 98.5F

You are a nurse on postpartum caring for a G6P4114 that is 4 hours postpartum after an emergent cesarean section (C/S). The patient delivered a viable infant male at 28 weeks gestation due to pre-eclampsia. She had been on magnesium sulfate for 23 hours prior to delivery and continues to be on magnesium sulfate. Her QBL (quantitative blood loss) in the C/S was 750mL. Upon examination you find that the patient’s fundus is boggy with heavy lochia rubra. It was determined that she is having a postpartum hemorrhage. Her QBL is now 1150 mL with continued hemorrhaging.  The provider is in the room and massaging the fundus. Which three priority interventions should the nurse do immediately? 

Rank the carbon atoms in order of increasing effective electronegativity for the compound below. Click to Show Image Description The structure shows a six-carbon ring with alternating double bonds. A C≡C group extends from the left side of the ring, and a C≡N group extends from the right side. Arrow I points to the left C≡C group, arrow II points to the lower-left carbon region of the ring, and arrow III points to the upper-right carbon region of the ring.  

In the video lectures for this class we discussed that the atomic electron configuration for ground state carbon (shown below) would not account for making four covalent bonds as in methane, CH4.  However, you can experimentally add energy to a carbon atom and pump the electrons to an excited state (shown below) with four unpaired electrons to make four covalent bonds.  Would such an atom offer a satisfactory model for the carbon in CH4?  If not, why not?    Click to Show Image Description The graphic shows two side-by-side orbital diagrams. In the ground-state carbon diagram, the 2s orbital has paired up and down arrows, the 2pₓ and 2pᵧ orbitals each have one upward arrow, and the 2pz orbital is empty. In the excited-state carbon diagram, the 2s orbital has one upward arrow, and the 2pₓ, 2pᵧ, and 2pz orbitals each have one upward arrow.

This question has four parts, A – D. Indicate where the following pharmaceuticals would be found physiologically: the blood (aqueous), tissues (less aqueous), or in lipids (least aqueous, hydrophobic).     Click to Show Image Description The skeletal chemical structure shows three fused rings across the top, with two outer six-membered rings containing alternating double bonds and a larger central ring. A three-carbon chain extends downward from the central ring and ends at an N atom. The N atom is bonded to two one-carbon groups. [AnswerA] Click to Show Image Description The skeletal chemical structure shows a central six-carbon benzene ring with four substituents. The upper-left substituent is a C(=O)OH group. The lower-left substituent is a sulfur-containing group shown as S bonded to two O atoms and an H₂N group. Cl is bonded to the lower-right side of the benzene ring. An HN group is bonded to the upper-right side of the ring and connects through CH₂ to a five-membered ring containing one O atom and two double bonds. [AnswerB] Click to Show Image Description The skeletal chemical structure shows a fused ring system on the left connected through a sulfur-containing linker to a six-membered ring on the right. The left fused system includes a six-carbon ring bonded to a five-membered ring containing two N atoms, one shown as N-H. A methoxy group extends from the left side of the fused ring. The sulfur linker is bonded to O with a double bond and connects to the right-hand ring through a one-carbon chain. The right-hand ring contains one N atom, two double bonds, two one-carbon branches, and one methoxy group. [AnswerC] Click to Show Image Description The skeletal chemical structure shows a fused two-ring system on the left, with an upper benzene ring fused to a lower six-membered ring. An HN group bonded to CH₃ extends from the left side of the lower ring on a dashed wedge bond. A solid wedge bond extends from the right side of the lower ring to a benzene ring on the right. The right benzene ring has two Cl substituents, one extending to the right and one extending downward. [AnswerD]   The compounds shown above (and the same are provided below) include: an antidepressant (must cross blood-brain barrier), a compound to release fluid buildup in kidneys, a muscle relaxant, and a stomach acid inhibitor (PPI).   Which one is which?   Click to Show Image Description The skeletal chemical structure shows three fused rings across the top, with two outer six-membered rings containing alternating double bonds and a larger central ring.
