NCO Fluid and Electrolytes Practice Exam

The primary concern for a client with a nasogastric tube set to low intermittent suction is to prevent electrolyte imbalance. This is due to the nature of gastric suctioning, where essential fluids, electrolytes, and nutrients can be lost from the body. The stomach plays a crucial role in maintaining electrolyte balance, and when a nasogastric tube is in place, especially attached to suction, there is a risk of removing not only gastric contents but also significant amounts of electrolytes like sodium, potassium, and chloride.

As the gastric contents are removed, the risk for developing imbalances increases, which can lead to clinical conditions such as hyponatremia or hypokalemia if not monitored and managed appropriately. Thus, consistent assessment of electrolyte levels and quick intervention is crucial to maintain homeostasis in the client.

Preventing dehydration is a concern, but the focus should be on electrolyte levels because dehydration is often a consequence of electrolyte imbalances, especially when the body loses fluid through gastric suction. Constipation, while important, is typically less urgent in the context of a nasogastric tube and does not directly relate to the immediate complications of the suctioning process. Preventing vomiting is also a valid consideration; however, the primary concern lies more
