Answer:
17 units
Explanation:
We are told in the question that:
The patient has been receiving 20 units of Lantus.
The order reads that if your patient is NPO, reduce Lantus by 15% , because. now the patient has become NPO (nothing through the mouth) for surgery
The amount to units to reduce Lantus by is calculated as:
15 % of 20 units
= 15% × 20 units
= 3 units.
Hence, if a patient is NPO the Lantus is reduced by 3 units
The number of units of Lantus should the patient receive now that he is NPO
is calculated as
= 20 units - 3 units
= 17 units.
Therefore, the number of units of Lantus should the patient receive now that he is NPO is 17 units.
