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 B
Explanation
A. Decrease the potential for thrombus formation: Metoclopramide is not used to prevent thrombus formation; this is typically managed with anticoagulants or other interventions.
B. Prevent postoperative nausea and vomiting: Metoclopramide is a prokinetic agent that helps in increasing gastric motility and is commonly used to prevent or treat nausea and vomiting after surgery.
C. Prolong the effects of anesthesia: Metoclopramide does not affect the duration of anesthesia. It is primarily used for nausea and vomiting.
D. Decrease postoperative pain: Metoclopramide does not have analgesic properties and is not used for pain management postoperatively.
Correct Answer is A
Explanation
A. Flush the tube: Flushing the tube before administering a feeding ensures that the tube is patent and free of blockages, which helps prevent aspiration or feeding tube complications.
B. Roll the patient flat: Rolling the patient flat is not necessary for administering a tube feeding, as most feeding tubes are positioned with the head of the bed elevated to reduce the risk of aspiration.
C. Check for a residual formula and return the residual to his or her stomach: While checking for residuals is important for assessing gastric emptying and tolerance to the feeding, it is not the first action before starting the feeding.
D. Place the end of the tube in water and check for bubbles: This action is used to check the placement of the tube (i.e., confirming it is in the stomach or intestine), but it’s not directly related to the initial steps before administering a feeding.
