After calibration of the multi-channel analyzer, what is the ideal relationship between the Cs-137 photopeak and the energy window? (Hint: consider the energy spectrum)

Define precision, define accuracy, and compare the two. You may include a drawing to demonstrate your understanding. 

Define scintillator and use one example from the lab exercises completed in class.

Identify the correct photopeak: The photopeak that occurs 28 keV below the primary photopeak is called the [photopeak1] The region that corresponds with the area of scattered gamma rays across a variety of angles, including events that are not absorbed in the crystal are called [photopeak2] The region that corresponds with the photopeak that results from internal conversion electrons and their resulting emission are called [photopeak3] The photopeak that occurs when a gamma ray transfers its energy into a scintillation crystal is called the [photopeak4]

A client with a sodium level of 122 mEq/L is confused and lethargic. What is the nurse’s priority action?

The nurse is preparing to administer an oral opioid analgesic to a client with acute pain. Before administering the medication, the nurse must assess the client’s:

Which clinical manifestation would most likely alert the nurse that a client is moving from simple restlessness into sensory overload?

A deaf client relying on lip-reading reports frustration because the nurses keep starting conversations before gaining their attention. To correct this, the nurse should prioritize which initial step before speaking?

A patient asks the nurse for a copy of their medical record. What is the nurse’s most appropriate response according to HIPAA guidelines?

In the immediate postoperative period, which assessment finding is the priority?
