A nurse is assessing a client who has heart failure. Which of the following client statements should indicate to the nurse that the client needs a referral for cardiac rehabilitation?

Rationale:

A. Check the client's airway and level of consciousness: The first priority is to assess the client's airway and level of consciousness to ensure that they are breathing properly and to gauge the severity of the condition.

B. Assess vital signs to determine hydration status: After assessing the airway and consciousness, it’s crucial to evaluate vital signs to determine the client's hydration status, as dehydration is a significant concern in diabetic ketoacidosis.

C. Administer prescribed IV fluids: IV fluids should be administered promptly to treat dehydration, restore electrolyte balance, and help improve circulation. This is typically the next step after assessing vital signs and hydration status.

D. Monitor for pulmonary edema: Once the IV fluids are being administered, the nurse should monitor for potential complications, such as pulmonary edema, which can occur due to fluid overload or other factors related to treatment.

Rationale:

A. Renal failure: The client has elevated creatinine levels (1.7 mg/dL), which suggests kidney impairment. This could be due to dehydration and osmotic diuresis associated with hyperglycemia, which is commonly seen in diabetic ketoacidosis (DKA) or hyperglycemic-hyperosmolar state (HHS).

B. Hypotension: The client’s blood pressure is low (96/65 mm Hg), which can be attributed to dehydration caused by excessive urination and hyperglycemia. Hypotension can worsen as the client becomes more dehydrated, potentially progressing to shock.

C. Cerebral edema: Cerebral edema is a rare but serious complication of diabetic ketoacidosis (DKA), particularly in younger patients and those with severe electrolyte imbalances. The rapid correction of hyperglycemia can cause osmotic shifts that may lead to cerebral edema. The client’s altered fluid balance increases this risk.

D. Septic shock: Although the client has a history of bronchitis and pneumonia, there is no evidence of active sepsis at this time. Septic shock is characterized by signs of infection, such as fever and widespread infection leading to organ dysfunction. This client’s symptoms point more toward a metabolic complication rather than sepsis.

E. Respiratory alkalosis: Respiratory alkalosis occurs when there is excessive loss of carbon dioxide due to hyperventilation. In this client, there is no indication of Kussmaul respirations to suggest respiratory alkalosis. The client is more likely to develop metabolic acidosis due to the presence of ketones and a low pH (7.30).

F. Cardiac arrhythmias: Elevated potassium levels (5.5 mEq/L) and the potential for rapid fluctuations in electrolytes in a client with DKA or HHS can increase the risk of cardiac arrhythmias. Potassium imbalances hyperkalemia or hypokalemia, are closely linked to arrhythmias.
