A nurse is performing an admission assessment on a client who had a recent positive pregnancy test. The first day of her last menstrual period (LMP) was May 8. According to Nägele's rule, which of the following dates should the nurse document as the client's estimated date of birth (EDB)?

A: Incorrect. Aspirin can trigger asthma attacks in some children and should be avoided.

B: Incorrect. The peak expiratory flow meter should be used daily, not just when the child has symptoms, and the highest reading should be recorded, not the average.

C: Incorrect. Carpet can harbor dust mites, mold, and other allergens that can worsen asthma. It is better to have hardwood or tile floors and washable rugs.

D: Correct. Influenza immunization can prevent serious complications from respiratory infections in children with asthma.

Electrolyte imbalance in pregnant clients is often associated with conditions that lead to dehydration and nutritional deficiencies. In this scenario, the key indicators are persistent nausea and significant weight loss.

• Persistent nausea can lead to reduced food and fluid intake. This condition, especially if prolonged, can cause dehydration and electrolyte imbalances due to the loss of essential minerals and nutrients that are not being replenished due to inadequate dietary intake.
• Significant weight loss, particularly the amount described in the scenario (6.8 kg or 15 lb), is a clear sign of inadequate nutritional intake and can further exacerbate the risk of electrolyte imbalance. It indicates that the body is not receiving enough nutrients, which is crucial for maintaining electrolyte balance.

The other options, while related to diet and fluid intake, are more specific to the client's eating habits and do not directly point to the primary cause of potential electrolyte imbalance in the context of this scenario. Therefore, the most comprehensive and medically relevant choice is (A) Persistent nausea and significant weight loss.
