Answer to Question 1

ANS: B
Measurement should be within 10 minutes of voiding. It is a postvoid so the measurement is after the patient voids and the urine volume is recorded. Patient is supine with head slightly elevated.

Answer to Question 2

ANS: B
Patients are not put under anesthesia for a CT scan; instead, the nurse should educate patients about the need to lie perfectly still and about possible methods of overcoming feelings of claustrophobia. The other options are correct and require no further teaching. Patients need to be assessed for an allergy to shellfish if receiving contrast for the CT scan. Bowel cleansing is often performed before CT scan. Another area to address is food and fluid restriction up to 4 hours prior to the test. After the procedure, encourage fluids to promote dye excretion.
