A community health nurse is planning care by using the family system approach. Which of the following methods should the nurse use to obtain Information about family function?

A. Weighing every other day is insufficient for heart failure management. Daily weight monitoring is essential to detect fluid retention early, as even small increases can indicate worsening heart failure and the need for medication adjustment.

B. Walking three or more times a week helps improve cardiovascular health and endurance without overexerting the heart. Regular, moderate exercise is recommended for heart failure clients to support functional status and prevent deconditioning.

C. Drinking 2.5 to 3 liters of water daily can lead to fluid overload in heart failure patients. These clients often require fluid restrictions to prevent worsening symptoms such as edema and shortness of breath due to impaired cardiac function.

D. Including whole milk with each meal increases saturated fat intake, which can worsen heart health. Low-fat dairy options are better suited for individuals with heart failure to manage cholesterol and cardiovascular risk.

A. Use a dandruff shampoo followed by drying the child's hair on high heat: Dandruff shampoos are not formulated to kill lice or nits, and while high heat may kill some lice, it is not a reliable or complete treatment. This approach may not effectively eliminate an active infestation.

B. Manually remove the lice eggs with a special comb: Manual removal using a fine-toothed nit comb is a safe and effective non-chemical method, especially suitable when natural remedies are preferred. This method ensures physical removal of lice and nits and is often recommended in combination with other treatments for full eradication.

C. Boil the child's combs, brushes, and hair accessories in water for 10 min: While this action is effective for preventing re-infestation by sanitizing personal items, it does not treat the lice on the child. It is an important environmental control measure but not a primary treatment strategy.

D. Apply mayonnaise to the child's head: Mayonnaise is sometimes cited as a natural remedy because it may smother lice, but there is limited evidence supporting its effectiveness. Additionally, it does not reliably kill nits and may not fully resolve the infestation without combing.
