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. Advise the client to avoid discussing the deceased with others: Avoiding discussion can intensify feelings of isolation and prevent processing of grief. Healthy grieving involves expressing emotions and sharing memories rather than suppressing them.
B. Encourage the client to focus on other areas of life to distract themselves: Distraction may provide temporary relief but does not address the underlying complicated grief. Encouraging avoidance of emotions can delay healing and exacerbate distress.
C. Refer the client to a bereavement counselor or therapist: Complicated grief involves prolonged, intense, or impairing symptoms that interfere with functioning. Referral to a mental health professional provides specialized assessment, support, and therapy to help the client process grief safely and effectively.
D. Suggest participating in daily physical exercise routines for emotional management: Physical activity can improve mood and reduce stress but is an adjunctive strategy. It does not replace professional intervention for complicated grief, which may require targeted psychotherapy or counseling.
Correct Answer is D
Explanation
A. Reposition the client to improve airway clearance: Positioning can help optimize ventilation and drainage of secretions, but it does not immediately correct hypoxemia in a client with oxygen saturation of 88%.
B. Notify the provider of the low oxygen level: While communication with the provider is important, immediate action to improve oxygenation takes priority over notification. Delaying intervention could worsen hypoxemia.
C. Increase fluid intake to mobilize secretions: Adequate hydration helps thin secretions over time but is not an immediate intervention to address critically low oxygen saturation.
D. Administer oxygen via nasal cannula as prescribed: Providing supplemental oxygen is the priority intervention to raise oxygen saturation and prevent tissue hypoxia. Immediate oxygen delivery directly addresses the client’s critical hypoxemia and stabilizes their respiratory status.
