A nurse on a medical-surgical unit is caring for a client who has a history of congestive heart failure (CHF). Complete the diagram by dragging from the choices below to specify what condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to assess the client's progress.

Rationale for Correct Choices: Hypovolemic shock: The client has received a high dose of IV diuretic (furosemide) and has drastically reduced urine output (30 mL in 1 hour), dizziness, and hypotension (BP dropped from 175/88 to 122/75 mm Hg). These are signs of intravascular volume depletion leading to hypovolemic shock. Administer IV fluids: This helps to restore circulating volume and prevent progression to shock. It improves perfusion to vital organs. Elevate the client's feet: This (Modified Trendelenburg) helps increase venous return to the heart and improve cardiac output during a hypotensive crisis. Pulse pressure: A narrowing pulse pressure (the difference between systolic and diastolic BP) is a classic sign of compensatory hypovolemic shock. Mental status: Changes in level of consciousness or increased confusion are early indicators of decreased cerebral perfusion in shock. Rationale for Incorrect Choices: Septic Shock: While the client has diabetes (a risk factor for infection), there are no clinical indicators of infection such as an elevated temperature or a history of fever. The 0100 temperature of 36.9°C (98.4°F) is normal. Obstructive Shock: This is caused by a physical obstruction to blood flow (like a tension pneumothorax or pulmonary embolism). The client's lung sounds are clear, and the clinical history specifically points to rapid fluid loss via diuresis rather than an obstructive event. Cardiogenic Shock: Although the client has CHF, cardiogenic shock usually presents with pulmonary congestion (crackles) and signs of pump failure. At 0100, the client’s lung sounds are clear and they are experiencing signs of dehydration (thirst, dizziness) after receiving 80 mg of IV furosemide, which indicates the low blood pressure is due to low volume (hypovolemia), not primary pump failure. Administer 1 unit of packed RBCs: This is indicated for hemorrhagic shock (blood loss). This client is losing fluid through urine (980 mL in 3 hours), not blood. Administer IV antibiotics: This would be the priority for septic shock. There is no evidence of infection in the provided notes or vitals. Obtain a lactate level: While lactate is a common lab for shock, it is specifically the "gold standard" for identifying tissue hypoperfusion in sepsis. In a clear case of over-diuresis leading to hypovolemia, the immediate priority is volume replacement. Blood culture: This is used to diagnose sepsis/septic shock, which is not supported by the client's clear lung sounds and normal temperature. Temperature: While important, it is not a specific indicator for monitoring progress in hypovolemic shock treatment; it is more relevant for infection. Platelet count: This would be monitored if the nurse suspected a clotting disorder or DIC (disseminated intravascular coagulation), often seen in advanced sepsis, but it does not help assess fluid resuscitation progress.
