1. A nurse is using a computerized documentation

system to record the vital signs of a patient. The nurse

notices that the system does not allow her to enter a

blood pressure value that is outside the normal range.

What is the most likely reason for this feature?

a) To prevent data entry errors

b) To alert the nurse to a potential problem

c) To ensure data quality and accuracy

d) To protect patient confidentiality

*Answer: c) To ensure data quality and accuracy

Rationale: Data quality and accuracy are essential for

health information systems, as they affect the

reliability and validity of the information and the

decisions based on it. A computerized documentation

system may have built-in validation rules that prevent

the entry of values that are implausible or inconsistent

with other data.

2. A nurse is working in a telehealth center that

provides remote monitoring and consultation services

to patients with chronic conditions. The nurse receives

a call from a patient who reports feeling dizzy and

having chest pain. What should the nurse do first?

a) Advise the patient to call 911 or go to the nearest

emergency department
