The practical nurse (PN) plans to administer a PRN dose of loperamide via a client's gastrostomy tube. The prescribed dose is 3 mg. The label on the medication bottle reads, "1 mg/5 mL." How many mL should the PN administer? (Enter numeric value only.)
The Correct Answer is ["15"]
Prescribed dose = 3 mg
Available concentration = 1 mg per 5 mL
Calculate the volume in milliliters (mL) to administer.
Volume (mL) = (Prescribed dose (mg) / Available concentration (mg)) x Available volume (mL)
= (3 mg / 1 mg) x 5 mL
= 3 x 5 mL
= 15 mL.

Correct Answer is A
Explanation
A. Instruct a UAP to keep the upper side rails up and check on the client every 15 minutes until the client is resting: Close supervision and use of safety measures such as raised side rails help prevent falls and injury. Frequent monitoring ensures the client’s safety while allowing time for the effects of pain medication and reorientation.
B. Administer a prescribed narcotic antagonist to reverse the effects of any analgesic accumulation: This is only indicated if there are signs of opioid overdose such as respiratory depression, not agitation or confusion. Administering a narcotic antagonist unnecessarily could reverse needed pain control.
C. Notify the healthcare provider and request a prescription for restraints to minimize the client's danger to self: Restraints are a last resort due to risks of injury and psychological distress. Other less restrictive interventions should be attempted first.
D. Raise the side rails and notify the family to come and stay until the client is reoriented and cooperative: While involving family may provide comfort, immediate close monitoring and safety measures take priority to prevent falls or injury.
Correct Answer is ["4.3"]
Explanation
Prescribed dose = 325 mg
Available concentration = 375 mg per 5 mL
Calculate the volume in milliliters (mL) to administer.
Volume (mL) = (Prescribed dose (mg) / Available concentration (mg)) x Available volume (mL)
= (325 mg / 375 mg) x 5 mL
= 0.8667 x 5 mL
= 4.335 mL.
Round the answer to the nearest tenth.
= 4.3 mL.
