A nurse is preparing to administer haloperidol 0.5 mg by mouth to an older adult client. The amount available is haloperidol oral concentrate 2 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 amount of haloperidol oral concentrate the nurse should administer, we can use the following equation:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
In this case, the dose is 0.5 mg and the concentration of the haloperidol oral concentrate is 2 mg/mL.
Volume (mL) = 0.5 mg / 2 mg/mL
Volume (mL) = 0.25 mL

Correct Answer is A
Explanation
a.This requires intervention because creases in the stockings can create pressure points that may lead to skin irritation or impaired circulation. The stockings should be applied smoothly and evenly to ensure proper compression and to avoid skin complications.
b.This is not necessary and can actually be incorrect. Antiembolic stockings should be applied with the correct side facing the client's skin. Turning them inside out could alter their effectiveness in providing the required compression.
c.This is appropriate. Applying antiembolic stockings before the client gets out of bed is recommended because it helps to promote venous return and prevent blood clots, especially if the client is immobile or has limited mobility.
d.This is appropriate. Asking the client to point their toes helps to ensure that the stockings can be applied correctly and fit well, reducing the risk of creating pressure points or causing discomfort.
Correct Answer is B
Explanation
During an intravenous pyelogram (IVP), a contrast dye is injected into the client's veins, and X-ray images are taken to visualize the urinary tract. The dye used in an IVP can cause a warming or flushing sensation as it circulates through the body. The client's statement indicates an understanding of this common sensation associated with the procedure.
"I can have a meal up to 2 hours before the procedure": This statement is incorrect. Typically, for an IVP, the client is required to have an empty stomach before the procedure to ensure accurate imaging results. The client should follow the specific instructions provided by their healthcare provider regarding fasting before the procedure.
"I do not need to sign a consent form before this procedure": This statement is incorrect. Informed consent is required for most medical procedures, including an IVP. The client should sign a consent form after receiving all the necessary information about the procedure, its risks, and benefits.
"I should limit my fluid intake for 2 days after the procedure": This statement is incorrect. After an IVP, it is generally advised to increase fluid intake to help flush out the contrast dye from the body and prevent potential complications. The client should follow the specific instructions provided by their healthcare provider regarding post-procedure fluid intake.
