A nurse is assessing a client's vital signs. Which vital sign reflects the number of times the heart beats per minute?

Answer: c. Faces Pain Scale - Revised (FPS-R) Explanation: The Faces Pain Scale - Revised (FPS-R) is commonly used for children who are too young to verbalize their pain intensity. It consists of a series of faces depicting different levels of pain intensity.

a. The Numeric Rating Scale (NRS) and Visual Analog Scale (VAS) require verbal or numerical expression of pain intensity, which may not be possible for young children.

d. The Wong-Baker FACES Pain Rating Scale is also commonly used for children and includes a series of faces to assess pain intensity, but the FPS-R is more widely used.

Answer: c. Notify the healthcare provider of the significant difference.

Explanation: A significant difference in blood pressure readings between the right and left arms may indicate arterial occlusion or other circulatory abnormalities. The nurse should notify the healthcare provider for further evaluation and intervention.

a. Rechecking the blood pressure with a different cuff size may be appropriate if the initial readings were inaccurate, but it does not address the significant difference between the arms.

b. Documenting the finding is important, but further action is required to investigate the cause of the discrepancy.

d. Performing a Doppler ultrasound may be done as part of the diagnostic process to assess blood flow, but the healthcare provider should be notified first for appropriate evaluation.
