A nurse is providing teaching about food selection to a client who has iron-deficiency anemia. Which of the following client statements should the nurse identify as an understanding of the teaching?

A) "Sit with your legs in a dependent position when in a chair."
Sitting with legs in a dependent position can decrease blood flow and increase the risk of clot formation. It's important to elevate the legs when sitting to promote venous return and reduce the risk of deep-vein thrombosis (DVT).

B) "Prevent dehydration by drinking at least 2.5 liters fluids each day."
Staying well-hydrated helps maintain good blood circulation and prevents blood from becoming too viscous, reducing the risk of clot formation. Adequate fluid intake is crucial in preventing DVT.

C) "Massage your calves after sitting for 2 hours."
Massaging the calves is not recommended for someone with a history of DVT, as it may dislodge a clot. Instead, clients should be encouraged to move or stretch their legs regularly to improve circulation.

D) "Roll stretchy nylon stockings down to the upper part of your calves."
Proper use of compression stockings involves wearing them as prescribed, which typically means keeping them fully extended to ensure consistent pressure along the leg. Rolling them down can create a tourniquet effect and is not recommended.

A) "If you experience angina, take a 10-minute rest period, then resume exercise."
It's important for clients to stop exercising immediately and consult a healthcare provider if they experience angina during exercise. Resting and then resuming exercise can be unsafe without medical advice, as angina indicates insufficient blood flow to the heart.

B) "Stop exercising if your heart rate increases by 20 beats per minute from baseline."
An increase in heart rate during exercise is expected, and stopping at a 20 BPM increase may be overly cautious. Clients should be taught to monitor for excessive fatigue or symptoms like dizziness, but a 20 BPM increase alone isn't necessarily a concern.

C) "Limit your exercise to an indoor facility to avoid exposure to the sun."
While excessive sun exposure can be a concern for some individuals, limiting exercise to indoors is unnecessary unless there are specific contraindications. Clients should be encouraged to exercise in environments they enjoy, with appropriate sun protection if outdoors.

D) "Begin by walking half a mile two times a day for the first week."
This recommendation is a reasonable starting point for postoperative exercise. Walking is a low-impact exercise that can help improve cardiovascular health gradually. Clients should gradually increase their activity level based on their tolerance and healthcare provider's advice.
