Explanation

Following a right-sided mastectomy, the right arm is considered the 'at-risk' limb due to potential disruption of the lymphatic system.
To prevent the complication of lymphedema (chronic swelling), all constrictive procedures, including blood pressure measurements, must be avoided on the affected side.
Taking the blood pressure on the unaffected (left) arm is the correct and safe priority action for monitoring the patient's hemodynamic status post-operatively.
Monitoring blood pressure is a higher priority than pulse oximetry in the immediate post-operative phase to detect complications like hemorrhage.

Option A: This action is contraindicated. Applying a constrictive blood pressure cuff to the arm on the side of a mastectomy can cause trauma and precipitate lymphedema.
Option C: While monitoring oxygen saturation is a standard part of post-operative care and should be done on the left side, assessing blood pressure is a higher priority for detecting immediate, life-threatening complications like hemorrhage or shock.
Option D: Any procedure or device, even one as seemingly minor as a pulse oximeter probe, should be avoided on the affected limb to minimize any risk of constriction, injury, or infection.

Clinical Relevance

Nursing practice connection: Safe nursing care depends on performing Post-Mastectomy Care and Limb Precautions in the correct sequence, documenting the action clearly, and monitoring for the expected response.
A critical nursing responsibility is to protect the patient from iatrogenic (treatment-induced) harm. Enforcing limb precautions after mastectomy is a key patient safety measure.
Nurses must place a 'Limb Alert' sign above the patient's bed and ensure a corresponding wristband is worn to communicate this precaution to all members of the healthcare team.
What if? If the patient had a pre-existing condition affecting the left arm (e.g., an AV fistula for dialysis, or paralysis from a stroke), taking blood pressure on either arm would be contraindicated. In this case, the nurse would need to use an alternative site, such as the thigh, and document this accordingly.

How to Approach the Question

First, identify the key elements of the clinical scenario: The patient is post-operative from a right-sided mastectomy.
Recall the primary complication associated with the affected limb after a mastectomy: lymphedema due to lymphatic system disruption.
Apply the standard nursing principle of 'limb precautions' for the affected side. This means avoiding any constrictive procedures like blood pressure readings, IVs, or blood draws.
Based on this principle, immediately eliminate any options that involve using the right arm (Options A and D).
Compare the remaining valid options (B and C). Both involve using the unaffected left side. The question asks for the 'priority' care.
Prioritize post-operative assessments. Monitoring for hemodynamic instability (e.g., hemorrhage, shock) via blood pressure is a higher priority than monitoring oxygen saturation in this initial post-op phase. Therefore, taking the BP is the priority action.

Concept Tested & Keywords

Concept Tested: Post-Mastectomy Care and Limb Precautions
Stem keywords: post-op, right side mastectomy, priority care
Lead-in keywords: priority care
Clinical cues: The procedure (right side mastectomy) directly informs the site-specific precaution.
