Answer to Question 1

ANS: C, D, E, F
The patient with B-positive blood may receive B-negative and B-positive blood as well as O-negative and O-positive blood. The patient does not have A-type antigens in his blood, so he cannot safely receive AB-positive or AB-negative blood.

Answer to Question 2

ANS: B
Serum potassium levels above 7.0 mEq/L can lead to dangerous cardiac arrhythmias, so the potassium level must be lowered promptly. Administration of IV insulin with 50 dextrose will push potassium into the cells to avoid hyperkalemia symptoms.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
