Order: Colace 25 mg PO PRN for constipation. Available: Colace 20mg/5ml. How much will the nurse give??
1.25ml
6.25ml
6.3mg
6 mg
The Correct Answer is B
A. 1.25ml: The dosage of 20mg/5ml means 1ml contains 4mg. To get 25mg, you need more than 1.25ml.
B. 6.25ml: Since 20 mg is in 5ml, to administer 25mg, you can use the following calculation:
25mg * 
= 6.25ml
C. 6.3mg: This is incorrect because the dosage needed is 25mg, not 6.3mg.
D. 6mg: The prescribed dose is 25mg, not 6mg.

Correct Answer is A
Explanation
A. Encourage turning, coughing, and deep breathing every 2 hours: Bed rest increases the risk of respiratory complications like atelectasis and pneumonia, so encouraging turning, coughing, and deep breathing helps prevent these complications by improving lung ventilation.
B. Raise the knee gatch to prevent the patient from sliding down in bed: While this may help position the patient, it is not the priority action to prevent complications related to bed rest and hepatitis.
C. Provide undisturbed periods of 6 hours to encourage rest: While rest is important, prolonged periods without movement can lead to complications like pneumonia or pressure ulcers. Movement should still be encouraged.
D. Restrict fluids: Fluid restriction is not necessary for most hepatitis patients unless there are specific complications like ascites or severe edema. Fluid intake should generally be encouraged to prevent dehydration.
