Radioactive iodine uptake test

24-hour cortisol urine study

Adrenocorticotropic hormone (ACTH) stimulation test

Edrophonium (Tensilon) test

Answer and Explanation

The Correct Answer is B

A. Radioactive iodine uptake test: This test is used to assess thyroid function and diagnose thyroid disorders, such as hyperthyroidism. It is not used to diagnose Cushing syndrome.
B. 24-hour cortisol urine study: This test measures cortisol levels in the urine over a 24-hour period and is commonly used to diagnose Cushing syndrome by evaluating elevated cortisol production.
C. Adrenocorticotropic hormone (ACTH) stimulation test: This test evaluates adrenal function and is typically used to assess adrenal insufficiency rather than Cushing syndrome.
D. Edrophonium (Tensilon) test: This test is used to diagnose myasthenia gravis, not Cushing syndrome. It evaluates the effect of the medication on muscle strength.

Correct Answer is ["75"]

Explanation

Step 1: Determine the total infusion time in hours
• There are 24 hours in a day.
Step 2: Calculate the infusion rate
• Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
• Infusion rate = 1800 mL / 24 hr = 75 mL/hr
Therefore, the nurse should set the IV pump to deliver 75 mL/hr.
