A nurse is teaching a client who has a prescription for alendronate 5 mg PO daily for osteoporosis. Which of the following client statements should the nurse identify as an understanding of the teaching?

A. Provide a low-potassium diet: Sickle cell anemia does not require a low-potassium diet. The focus should be on hydration and pain management during a vaso-occlusive crisis, not dietary restrictions unless indicated for other reasons.

B. Apply cold compresses to joints: Cold compresses are not recommended during a vaso-occlusive crisis. Cold can constrict blood vessels and worsen pain. Heat therapy is typically more effective for alleviating pain during a crisis, as it promotes vasodilation and blood flow.

C. Implement a fluid restriction: Fluid restriction is not recommended for a child experiencing a vaso-occlusive crisis. Increasing fluid intake is crucial during a crisis to help reduce blood viscosity and prevent further occlusion of blood vessels.

D. Maintain bed rest: Bed rest is appropriate during a vaso-occlusive crisis. Limiting physical activity can help reduce the body's oxygen demand and prevent further strain on the cardiovascular system. Rest can also alleviate pain and fatigue during the crisis.

A. "Avoid exposing your baby to secondhand smoke.": Exposure to secondhand smoke is a significant risk factor for otitis media in infants. Smoke irritates the respiratory system and can contribute to Eustachian tube dysfunction, which increases the likelihood of ear infections.

B. "Ensure your baby receives the Hepatitis B vaccine.": While vaccination is important for overall health, the Hepatitis B vaccine is not specifically related to the prevention of otitis media. The focus should be on risk factors that directly affect ear infections.

C. "Place your baby in a supine position during feeding.": Placing an infant in a supine position during feeding increases the risk of otitis media. The recommended position is an upright or semi-upright position, which helps prevent milk from flowing into the Eustachian tube.

D. "Switch from breastfeeding to formula feeding when your baby is 2 months old.": Breastfed infants have a lower incidence of ear infections compared to formula-fed infants due to the immune protection provided by breast milk. Therefore, breastfeeding should continue.
