A client arrives at a hurricane disaster medical area seeking treatment for diarrhea.

Which source of contamination should the nurse consider when interviewing the client about exposure?

Choice A rationale:

Checking the femoral site for hematoma formation is the most appropriate action in response to the client's complaint of pain at the right groin insertion site after a cardiac catheterization. Hematoma formation is a potential complication of this procedure and can lead to further complications if not addressed promptly. Checking for hematoma allows the nurse to assess for bleeding and take appropriate measures to manage it.

Choice B rationale:

Stimulating the client to take deep breaths is not the most immediate action needed in this situation. While deep breathing is important for respiratory function, the client's pain at the groin site requires immediate assessment to rule out complications.

Choice C rationale:

Evaluating the integrity of the IV insertion site is not the primary concern in this case. The client's pain is localized to the groin site, which is where the cardiac catheterization was performed. Checking for hematoma formation at this site takes precedence.

Choice D rationale:

Assessing distal lower extremity capillary refill is important for assessing peripheral perfusion, but it is not the most immediate action needed when a client complains of pain at a specific site, such as the right groin insertion site after a cardiac catheterization. Checking for hematoma and assessing for bleeding should come first.

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.
