A nurse is preparing to administer haloperidol 5 mg IM to a client. The amount available is haloperidol 20 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.25"]
To calculate the volume of haloperidol solution needed, we can use the formula:
Volume (mL)=Dose (mg)/Concentration (mg/mL)
Given: Dose of haloperidol = 5 mg
Concentration of haloperidol solution = 20 mg/mL
Substituting the given values into the formula:
Volume (mL)=5 mg/20 mg/mL
Volume (mL)=5/20
Volume (mL)=0.25 mL
Rounded to the nearest hundredth, the nurse should administer 0.25 mL of haloperidol solution.

Correct Answer is D
Explanation
A. Grapefruit juice inactivates this medication - Grapefruit juice is known to interact with certain medications, but it does not affect the metabolism of diazepam. Therefore, this statement is incorrect.
B. It is important to avoid foods that contain tyramine - Tyramine is typically associated with interactions with monoamine oxidase inhibitors (MAOIs), not benzodiazepines like diazepam. Therefore, this statement is incorrect.
C. This medication must be swallowed whole - While it is generally recommended to swallow diazepam tablets whole with a full glass of water, this instruction does not encompass the full range of information necessary for safe medication use.
D. Diazepam can cause drowsiness - This statement is correct. Diazepam, like other benzodiazepines, has sedative effects and can cause drowsiness. Patients should be advised to avoid activities that require mental alertness, such as driving, until they know how the medication affects them. This is an essential aspect of patient education regarding diazepam.
Correct Answer is ["75"]
Explanation
To calculate the infusion rate in mL/hr for total parenteral nutrition (TPN) we divide the total volume by the total infusion time.
Given: Total volume of TPN = 1800 mL Total infusion time = 24 hours
Infusion rate (mL/hr) = Total volume / Total infusion time
Substituting the given values: Infusion rate = 1800 mL / 24 hr ≈ 75 mL/hr
Rounded to the nearest whole number, the nurse should set the IV pump to deliver approximately 75 mL/hr of TPN.
