A client with intestinal obstruction has a nasogastric tube to low intermittent suction and is receiving an intravenous (IV) infusion of lactated Ringer's at 100 mL/hour.
Which finding is most important for the nurse to report to the healthcare provider? Reference Range: Potassium (3.5 to 5 mEq/L (3.5 to 5 mmol/L).

Choice A rationale:

History of vomiting at home for 3 days prior to surgery. Rationale: This information is relevant to the client's surgical history and may impact their current condition. It is essential to inform the receiving nurse about this history to ensure appropriate postoperative care.

Choice B rationale:

Soft abdomen, absent bowel sounds, no bleeding on dressing. Rationale: While this information is important for assessing the client's postoperative status, it is less urgent than the history of vomiting. The abdominal assessment suggests normal findings after surgery.

Choice C rationale:

Declining to take ice chips for complaints of dry mouth. Rationale: While this information indicates the client's complaint of dry mouth, it is not as critical as the history of vomiting or the assessment of surgical outcomes.

Choice D rationale:

Peripheral pulses present with full range of motion of both legs. Rationale: This information is important but primarily related to the client's vascular and neurological status. It may not be as immediately relevant as the history of vomiting in the context of a recent surgery.

Choice A rationale:

Correcting electrolytes that are out of normal range is a crucial goal of therapy for this client. In diabetic ketoacidosis (DKA), the body’s cells are unable to use glucose for energy due to a lack of insulin. This leads to the breakdown of fat for energy, producing ketones as a by-product. Ketones are acidic and can cause the blood’s pH to decrease, leading to metabolic acidosis. This process also leads to an increased production and excretion of electrolytes such as potassium and sodium. Therefore, correcting these electrolyte imbalances is a key goal of therapy.

Choice B rationale:

While promoting oxygenation to tissues is generally important in critical care, it is not a specific goal in the management of DKA. The primary issues in DKA are metabolic in nature, including hyperglycemia, ketosis, and acidosis.

Choice C rationale:

Preventing hyperventilation is not a specific goal in the management of DKA. Hyperventilation in DKA is a compensatory mechanism for metabolic acidosis (Kussmaul breathing). The body tries to expel more carbon dioxide to reduce the acidity of the blood.

Choice D rationale:

Reversing dehydration is another important goal of therapy for this client. In DKA, high blood glucose levels lead to osmotic diuresis, where water is drawn into the urine from the blood, leading to dehydration. This can cause hypotension and reduced tissue perfusion. Therefore, reversing dehydration through fluid replacement is a key part of treatment.

Choice E rationale:

Replacing insulin is a fundamental goal of therapy for this client. Insulin deficiency is the primary cause of DKA. Insulin allows glucose to enter cells where it can be used for energy, preventing the breakdown of fat for energy and the subsequent production of ketones.

Choice F rationale:

Providing respiratory support may be necessary in severe cases of DKA where the patient’s compensatory respiratory efforts are insufficient to maintain adequate gas exchange. However, it is not one of the primary goals of therapy in DKA management.
