The nurse is caring for a client who just had a subclavian central venous catheter inserted. Which symptom should the nurse recognize as setting a priority for this client's care?

C. Dehydration is a state of insufficient fluid intake or excessive fluid loss, leading to electrolyte imbalances and increased concentrations of solutes in the blood. The elevated sodium level (hypernatremia) and slightly elevated glucose level in the context of dehydration are consistent with the laboratory findings. Dehydration can also cause elevated BUN due to decreased kidney perfusion and impaired renal function secondary to hypovolemia. Therefore, dehydration is the most likely condition based on the laboratory findings.
A. SIADH is characterized by excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia (low sodium levels). In this case, the sodium level is elevated, which is not consistent with SIADH. Therefore, SIADH is unlikely.

B. Low-protein diet is not typically associated with the laboratory findings presented. Low protein intake would not directly cause elevated sodium, potassium, glucose, or BUN levels. Therefore, this option is unlikely.
D. Renal failure is characterized by impaired kidney function, resulting in electrolyte imbalances, elevated BUN, and abnormal creatinine levels. However, the creatinine level in this case is within the normal range, suggesting preserved kidney function. Additionally, the elevated sodium level is not typically associated with renal failure. Therefore, renal failure is less likely.

A. One of the primary purposes of inserting an NG tube is to decompress the stomach by removing gastric contents. In the case of abdominal distention and severe vomiting, excess gas and fluid accumulation in the stomach can contribute to discomfort and further vomiting. The NG tube provides a way to suction out these contents, relieving pressure and reducing symptoms.
B. NG tubes can also be used to administer medications directly into the stomach. This route is particularly useful when a client is unable to take medications orally due to vomiting or other gastrointestinal issues. Medications can be crushed and dissolved in liquid form before being administered through the NG tube.
C. In some situations, such as when assessing for gastrointestinal bleeding or checking for tube placement, it may be necessary to determine the pH of gastric secretions. Gastric aspirate obtained through the NG tube can be tested for acidity, which can help confirm that the tube is correctly positioned in the stomach and provide information about the client's digestive function.
D. While NG tubes can be used to supply nutrients via tube feedings, this is not typically the primary rationale for their use in the acute situation described (abdominal distention and severe vomiting). However, in cases where a client is unable to tolerate oral intake due to their condition, tube feedings can be administered through the NG tube to provide essential nutrients and maintain nutritional status.
