Answer to Question 1

B
The patient is experiencing a hypersensitivity reaction to the phytonadione, which is manifested by impending respiratory distress associated with IV administration of the drug.
Mild pruritus may be significant, but the pulse is within normal limits. The greatest concerns are the low O2 sats and bronchoconstriction .
There is no indication of how long the patient was exposed to warfarin, therefore sensitization is not a correct choice.
A blood pressure of 107/52 is not significant, because it may be baseline for the patient. Bleeding gums are an anticipated effect of excessive warfarin and would not be a significant finding after administration of the vitamin K.

Answer to Question 2

C, D, E
Vitamin B6 deficiency likely is related to alcoholism or the use of isoniazid, which prevents conversion of the vitamin to its active form and may induce symptoms of deficiency, such as se-borrheic dermatitis, microcytic anemia, peripheral neuritis, convulsions, depression, and confu-sion.
Vitamin B6 deficiency does not induce sprue or glossitis.
