A 24-year-old with diabetic ketoacidosis is admitted to the ED and his blood glucose on arrival was 780. He has been started on an insulin drip and has received one amp of bicarb. The nurse will be doing finger stick blood sugars every hour. ABG results are: pH= 7.31 PaCO2= 25 mm/Hg HCO3=12 mmol/l 1. The graduate nurse asks the preceptor to help with interpretation of the blood gases. How should the preceptor interpret these values and explain the reasons for the changes?

  • Apply Kurt Lewin - Change theory in a Advance Practice Registered Nurse practice as Nurse Practitioner site that address social needs, education needs, life process changes, you want to make in advance practice as in a practice site.
  • How would you describe Kurt Lewin - Change theory reflect the work of the FNP as a Primary Care Provider therefore the change should be in outpatient settings.
  • How becoming an Advance Practice Registered Nurse (APRN) nurse practitioner could make a difference in applying this change.

Which one of the following statements is incorrect?


Which one of the following statements is incorrect?

 1) Scarcity is a universal phenomenon that arises because resources are limited

 2) Microeconomics is the branch of economics which studies how individual decision-makers behave and interact with each other

 3) Macroeconomics is the branch of economics which studies the functioning and performance of a society's economy as a whole (often with a focus on levels of and changes in aggregate measures such as the unemployment rate, inflation rate, and Gross Domestic Product growth rate).

 4) Macroeconomics focuses on the individual unit (i.e., it examines the "trees")

b. Consider the current economic conditions in Australia, where (even though official data is not yet in) current output (real GDP) is currently below potential GDP.

(i) What type of fiscal policy has the government used to try and get Australia to potential GDP? Draw an AD-AS diagram to illustrate this situation (including the initial situation). Explain the figure in some detail. By this, we mean do not just explain the changes in the diagram, but also state what components of the AD and AS curves are changing (if any), and in which direction.

  1. An antibody can bind to a coronavirus receptor with a koffand kon rate of 10-5s-1and 104M-1s-1, respectively. If there are 10 µM total receptors and 50 µM free antibody, what concentration of coronavirus receptors are bound with antibody? What percent of receptors are bound?
  2. The coronavirus mutated its receptor which changes the dissociation rate koff to 1 s-1for the antibody. How does this change the percent of receptors bounds?
  3. How long does the antibody stay bound to the wildtype receptors vs. the mutated receptors?

Consider a galvanic cell based on the following two half reactions at 298 K: SRP Fe3+ + e-  Fe2+ 0.77 V Cu2+ + 2 e-  Cu 0.34 V How many of the following changes will increase the potential of the cell? Why?

1. Increasing the concentration of Fe+3 ions

2. Increasing the concentration of Cu2+ ions

3. Removing equal volumes of water in both half reactions through evaporation

4. Increasing the concentration of Fe2+ ions

5. Adding a NO3 - solution to the anode portion of the cell
