A nurse is assessing a client's blood pressure using the two-step method. Which error could lead to inaccurate readings?
Allowing the client to talk during the measurement.
Using a cuff that is too small for the client.
Positioning the client's arm below heart level.
Using the same arm repeatedly without a break
The Correct Answer is B
A. Allowing the client to talk during the measurement: Talking can cause slight elevations in blood pressure readings but is generally less impactful than using an incorrectly sized cuff. Proper technique still allows accurate assessment if the client remains mostly still and quiet.
B. Using a cuff that is too small for the client: A cuff that is too small increases the pressure required to occlude the artery, resulting in falsely high blood pressure readings. Correct cuff size is essential for accurate measurement, making this the most significant error.
C. Positioning the client's arm below heart level: An arm below heart level can elevate readings slightly due to hydrostatic pressure, but the effect is usually less than that caused by an improper cuff size. Proper positioning remains important for accuracy.
D. Using the same arm repeatedly without a break: Repeated measurements without a short rest may cause discomfort or transient changes but is unlikely to produce as significant an error as using an incorrectly sized cuff. Rotating arms or allowing rest can improve reliability.

Correct Answer is C
Explanation
A. Introduce themselves and ask about the client's health history: While establishing rapport and obtaining history are essential, these actions occur after ensuring the environment is safe for both the nurse and client.
B. Verify the client's identity and confirm the care plan: Confirming identity and care plans is important for accurate care delivery but is secondary to assessing environmental safety. Unsafe conditions could compromise the nurse’s ability to provide care.
C. Perform a quick assessment of the home environment for potential hazards: The first priority in home health visits is personal safety. Assessing for hazards such as loose rugs, pets, unsafe stairs, or potential threats ensures the nurse can safely provide care without risk of injury or harm.
D. Set up a workspace for documentation and equipment: Organizing the workspace is necessary for effective care but should follow the initial environmental and personal safety assessment. Unsafe surroundings take precedence over workflow setup.
Correct Answer is D
Explanation
A. Ignore as it is not the nurse's responsibility: Maintaining patient confidentiality is a shared professional and legal responsibility. Ignoring a breach could violate HIPAA regulations and ethical standards, placing patients and staff at risk.
B. Wait for the colleague to return and discuss the issue with them: Waiting delays immediate protection of sensitive information and could result in unauthorized access. Patient privacy must be addressed without delay.
C. Inform the hospital administration immediately: While reporting repeated breaches may be appropriate, the immediate concern is to secure the information to prevent exposure. Administrative reporting alone does not address the urgent risk.
D. Close the computer screen and remind the colleague to log out: Securing the unattended computer prevents unauthorized access to patient records and maintains confidentiality. Promptly reminding the colleague reinforces professional accountability and compliance with privacy regulations.
