A nurse is providing breast self-examination teaching to a client who is menopausal. Which of the following statements should the nurse identify as an indication that the teaching was effective? (Select all that apply.)

Choice A reason:
Hemodialysis does not typically result in a significant decrease in RBC count. While there can be a minimal loss of red blood cells during the process, it is not the primary focus of the treatment. The main purpose of hemodialysis is to remove waste products and excess fluid from the blood when the kidneys are not functioning properly.

Choice B reason:
Calcium levels may vary during hemodialysis, and the treatment can be adjusted to prevent significant changes in calcium levels. Hemodialysis can remove some calcium from the blood, but it is usually not the most affected value, and calcium can be added to the dialysate solution if necessary.

Choice C reason:
Potassium is one of the primary electrolytes removed during hemodialysis. High levels of potassium, which can be life-threatening, are commonly seen in clients with renal failure. Hemodialysis effectively reduces high potassium levels, which is crucial for preventing complications such as cardiac arrhythmias.

Choice D reason:
Protein levels are not directly targeted by hemodialysis, and significant protein loss is not a usual outcome of the treatment. The dialysis membrane is designed to allow smaller molecules like urea and potassium to pass through while retaining larger molecules like proteins.

Choice A reason:
The inability to move toes can be an early sign that a cast is too tight. This symptom may indicate that the cast is impinging on nerves or blood vessels, leading to decreased motor function. It is essential to address this immediately to prevent further complications such as permanent damage or compartment syndrome.

Choice B reason:
Edema, or swelling of the toes, can occur if a cast is too tight, but it may not be the first sign observed. Swelling is a response to increased pressure in the tissues and can develop over time as fluid accumulates. While it is a concern, it often follows other symptoms such as changes in sensation or movement.

Choice C reason:
Pallor of the toes, indicating reduced blood flow, can be a sign of a cast that is too tight. However, pallor may not be as immediately noticeable as the inability to move toes or changes in sensation. It is still a critical sign that requires prompt evaluation and possible adjustment of the cast.

Choice D reason:
A change in the temperature of the toes, such as them becoming cooler to the touch, can suggest impaired blood flow due to a tight cast. This sign, along with pallor, may develop after other symptoms such as numbness or motor impairment.
