A nurse in a provider's office is reinforcing teaching about skin care with a client who has a new diagnosis of systemic lupus erythematosus. Which of the following statements by the client indicates an understanding of the teaching?

Pain in the calf can be a potential symptom of deep vein thrombosis (DVT), which is a serious complication after surgery. Monitoring the client's pulse oximetry can help assess for signs of decreased oxygenation, which may indicate a possible clot or compromised circulation. A decrease in oxygen saturation can be an early indicator of a potential DVT-related complication, such as a pulmonary embolism. Monitoring the pulse oximetry can provide valuable information for timely intervention and management.

Instructing the client to massage the calf gently is not advisable without further assessment and evaluation. Massaging the calf can potentially dislodge a clot if one is present, leading to further complications. It is important to rule out DVT through appropriate diagnostic measures before providing specific instructions for calf massage.

Maintaining the leg in a dependent position while in bed can potentially worsen the symptoms and increase the risk of venous stasis. Elevating the affected leg, rather than maintaining it in a dependent position, can help improve venous return and reduce pain or swelling.

Applying a cold compress to the client's calf is not recommended without further assessment. Heat or cold therapy should be applied based on the underlying cause of the pain. In the case of potential DVT, applying a cold compress can increase vasoconstriction and potentially worsen the condition. It is essential to investigate the cause of the pain first and consult with the healthcare provider before initiating any specific therapies or interventions.

This statement shows that the client understands the threshold for high blood pressure readings. A blood pressure reading of 140/90 mmHg or higher is considered elevated or hypertensive.

It is important for the client to be aware of this value and to seek medical attention or follow the prescribed management plan if their blood pressure exceeds this threshold.

The hand should be supported at the level of the heart or positioned comfortably during blood pressure measurement, but it does not need to be specifically 6 inches below the heart.

Consistency in the timing of blood pressure measurements is important for accurate monitoring. It is generally recommended to measure blood pressure at the same time each day to account for variations that can occur throughout the day.

The blood pressure cuff should be snug but not too tight around the upper arm. It should fit comfortably and securely to ensure accurate readings.
