  2. A
  3. B
  4. AB

Question 2

The nurse determines that a patient is experiencing ongoing progression of a shock state. What finding led the nurse to come to this conclusion?
 
  1. decrease in serum glucose level
  2. drop in blood urea nitrogen level
  3. increased eosinophil level
  4. low serum cardiac enzyme level

Answer to Question 1

Correct Answer: 1

Type O blood is the universal donor. ABO antibodies develop in the serum of people whose RBCs lack the corresponding antigen; these antibodies are called anti-A and anti-B. The person with blood type B has A antibodies, the person with type A has B antibodies, the person with type O has both types of antibodies, and the person with AB has no antibodies (called a universal recipient).

Answer to Question 2

Correct Answer: 1

Serum electrolyte levels are assessed to monitor the severity and progression of shock. As shock progresses, serum glucose levels decrease. A drop in blood urea nitrogen level means the kidneys are receiving adequate blood flow. An increase in eosinophils indicates an allergic response. Low serum cardiac enzymes indicate there is no myocardial damage.
