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) Position the cast on a plastic-covered pillow:
Positioning the cast on a plastic-covered pillow is not recommended because the plastic can trap moisture and heat, potentially affecting the cast's integrity as it dries. Instead, a soft, absorbent material should be used to support the cast.

B) Perform neurovascular checks every 2 hr:
Frequent neurovascular checks are essential to monitor for complications such as compartment syndrome, nerve damage, or impaired circulation. This action helps ensure that any changes in sensation, movement, or circulation are identified and addressed promptly.

C) Instruct the client to avoid moving the fingers on the left hand:
Encouraging the client to move their fingers is important to prevent stiffness and swelling and to promote circulation. Instructing the client to avoid moving their fingers is not appropriate and could lead to complications.

D) Touch the cast with the palms of the hands when moving the client:
Handling a wet plaster cast with the palms of the hands is correct to prevent indentations and pressure points that could cause skin irritation or pressure sores. However, this action is not as critical as performing frequent neurovascular checks to ensure the client's safety and monitor for complications.

A) Cimetidine: Cimetidine is an H2 receptor antagonist used to reduce stomach acid and treat conditions such as peptic ulcers and gastroesophageal reflux disease (GERD). It is not used to manage metabolic acidosis.

B) Calcitonin: Calcitonin is used to regulate calcium levels and treat conditions like osteoporosis or hypercalcemia. It does not address metabolic acidosis and is not appropriate for this condition.

C) Sodium bicarbonate: Sodium bicarbonate is commonly used to treat metabolic acidosis. It works by neutralizing excess acid in the blood, thereby increasing the blood's pH and helping to correct the acid-base imbalance associated with metabolic acidosis.

D) Sodium chloride: Sodium chloride is a salt that can be used to manage fluid and electrolyte imbalances but does not correct metabolic acidosis. It is not suitable for treating the acid-base imbalance seen in metabolic acidosis.
