The physician orders Lanoxin elixir 90 mcg PO every morning.
Drug available: Lanoxin elixir 0.05 mg/mL
How many mL will be given?
The Correct Answer is ["1.8"]
First, let's convert 90 mcg to mg:
90 mcg = 0.09 mg
Next, we can use dimensional analysis to calculate the required mL: 0.09 mg Lanoxin x 1 mL/0.05 mg Lanoxin = 1.8 mL
Therefore, the nurse will give 1.8 mL of Lanoxin elixir.
Rounding to the nearest tenth, the answer is 1.8 mL.

Correct Answer is D
Explanation
Upon discovering that the client's abdominal wound has been eviscerated, the nurse should immediately cover the wound area with sterile gauze moistened with sterile 0.9% normal saline. This will help to protect the exposed organs and prevent them from becoming dry or exposed to contaminants. Pouring hydrogen peroxide into the abdominal cavity can cause further damage to the exposed organs and is not recommended. Similarly, normal saline should be gently poured on the area to moisten it, but organs should not be placed back into the cavity as this can cause further injury. Attempting to close the wound area with reinforced adhesive skin closures is also not appropriate as the wound needs to be assessed and repaired by a healthcare provider. The nurse should call the healthcare provider and provide ongoing assessment and support to the client while waiting for further interventions.
Correct Answer is ["0.2"]
Explanation
Each mL contains 5,000,000 units. Therefore, to administer 1,000,000 units, we need:
1,000,000 units / 5,000,000 units/mL = 0.2 mL
So, the nurse will give 0.2 mL of reconstituted penicillin G to the client.
