A client is ordered to receive 4 g of a medication. The pharmacy has the medication available in a concentration of 160 mg per 5 mL. How many mL should the client receive?
The Correct Answer is ["125"]
To calculate the amount of mL that the client should receive, we need to use the formula:
mL = (g * 5 mL) / mg
where g is the ordered dose of the medication, mg is the concentration of the medication, and mL is the volume of the solution.
Plugging in the given values, we get:
mL = (4 g * 5 mL) / 160 mg
Simplifying, we get:
mL = 0.125 g/mL
Multiplying by 1000 to convert grams to milligrams, we get:
mL = 125 mg/mL
Therefore, the client should receive 125 mL of the solution.

Correct Answer is ["0.75"]
Explanation
The nurse needs to calculate the correct dose of atropine for a client who has a prescription for 0.3 mg IV stat. The nurse knows that atropine is a medication that blocks the effects of the parasympathetic nervous system and is used to treat bradycardia, heart block, and some types of poisoning.
To find out how many milliliters of atropine the nurse will administer, the nurse can use the formula:
Dose ordered / Dose available = Volume to administer
Plugging in the values, the nurse gets:
0.3 mg / 0.4 mg per mL = 0.75 mL
Therefore, the nurse will administer 0.75 mL of atropine to the client IV stat.
Correct Answer is A

B. “The older I get the higher my risk for peripheral arterial disease gets.”

C. “Since my family is from Italy, I have a higher risk of developing peripheral arterial disease.”
Explanation: Family history is a non-modifiable risk factor, and the statement correctly identifies this risk factor. However, it doesn't address modifiable factors or actions to reduce risk.
