A nurse is educating the parent of a school-age child about the importance of maintaining water intake to prevent dehydration. Which of the following food choices should the nurse recommend as containing the greatest percentage of water?

The correct answer is choice B: Muscle weakness.

Choice A rationale:

Exaggerated reflexes are not typically associated with water intoxication. They can be a sign of other neurological conditions but not specifically related to the administration of hypotonic IV fluids.

Choice B rationale:

Muscle weakness is a symptom of water intoxication, which can occur due to the dilution of electrolytes, including sodium, in the body when a hypotonic solution is administered.

Choice C rationale:

Hypernatremia, or high levels of sodium in the blood, is the opposite of what occurs in water intoxication. Water intoxication leads to hyponatremia, which is a low sodium concentration in the blood.

Choice D rationale:

Weak pulses are not a direct indicator of water intoxication. While they can be associated with various conditions, they do not specifically point to water intoxication following the administration of a hypotonic IV fluid bolus.

Choice A rationale:
Soft, formed bowel movements indicate effective probiotic therapy. Probiotics are live microorganisms that confer health benefits when consumed in adequate amounts. They can promote gut health and regular bowel movements by restoring the balance of intestinal flora. The presence of soft, formed stools suggests that the probiotics are aiding in digestion and maintaining a healthy gut environment.
Choice B rationale:
The pinkness of mucous membranes is not a direct indicator of the effectiveness of probiotic therapy. While probiotics can have systemic effects on the body, such as enhancing the immune system, mucous membrane color is more influenced by factors like oxygenation and hydration status.
Choice C rationale:
The ability to complete activities of daily living (ADLs) is not a specific marker of the effectiveness of probiotic therapy. Probiotics primarily impact gastrointestinal health and digestion. ADLs reflect a client's overall functional status, which can be influenced by various factors beyond probiotic use.
Choice D rationale:
Blood glucose level being within the expected reference range is not directly related to probiotic therapy. The question stem mentions that the client is receiving parenteral nutrition, which means they are likely not consuming food orally, reducing the impact of dietary factors on blood glucose levels. Blood glucose levels are more affected by factors like insulin administration and the body's glucose utilization.
