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.

"I will not allow anyone to smoke near my baby."

• A. Correct. Avoiding exposure to tobacco smoke is one of the measures to prevent SIDS, as it can affect the respiratory function and arousal of the newborn.
• B. Incorrect. Placing bumper pads in the baby's crib is not recommended, as they can pose a suffocation or strangulation hazard for the newborn.
• C. Incorrect. Placing the baby's head on a pillow for sleeping is not advised, as it can increase the risk of suffocation or rebreathing of carbon dioxide for the newborn.
• D. Incorrect. Placing the baby in a side-lying position for sleeping is not suggested, as it can increase the likelihood of rolling over to a prone position, which is associated with a higher incidence of SIDS.
