.A nurse is preparing to administer vitamin K 1mg IM to a newborn. Available is vitamin K injection 1 mg/0.5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
To determine the correct volume to administer, we use the formula for calculating the dose:
Volume to administer=Prescribed dose ÷ Available concentration
Given:
● Prescribed dose: 1 mg
● Available concentration: 1 mg per 0.5 mL
Plugging in the values:
Volume to administer=1 mg÷ 1 mg/0.5 ml
Perform the division:
Volume to administer=0.5 mL
So, the nurse should administer 0.5 mL per dose.
Since the question specifies rounding to the nearest tenth and to use a leading zero if it applies (and not to use a trailing zero), the final answer is: 0.5 mL

Explanation
To calculate the volume of haloperidol 5 mg to administer, we'll use the formula:
Volume (mL)=Dose (mg)/Concentration (mg/mL)
Given:
Dose = 5 mg
Concentration = 50 mg/mL
Plugging these values into the formula:
Volume (mL)=5 mg÷50 mg/mL
Volume (mL)=1÷10
So, the nurse should administer 0.1 mL of haloperidol per dose.
Correct Answer is D
Explanation
A. "Type 2 diabetes": Type 2 diabetes is characterized by insulin resistance and relative insulin deficiency but not by a complete lack of insulin production.
B. Neither-they both result from the inability of the body to use insulin: This is incorrect as Type 1 diabetes results from the pancreas not producing insulin, while Type 2 diabetes involves insulin resistance.
C. "Both type 1 and type 2 diabetes": This is incorrect as only Type 1 diabetes is caused by no insulin secretion. Type 2 diabetes involves different pathophysiological mechanisms.
D. "Type 1 diabetes": Type 1 diabetes is characterized by the pancreas's inability to produce insulin due to autoimmune destruction of insulin-producing beta cells. This type of diabetes requires insulin therapy for management.
