A nurse is collecting a medication history from a client who is scheduled to have a cardiac catheterization. Which of the following medications taken by the client interacts with contrast material and places the client at risk for acute kidney injury?

Choice A: Increased Respiratory Rate

Fluid overload, also known as hypervolemia, can lead to an increased respiratory rate. This occurs because the excess fluid in the body can accumulate in the lungs, leading to pulmonary congestion and edema. As a result, the body attempts to compensate by increasing the respiratory rate to improve oxygenation and remove excess carbon dioxide. Normal respiratory rate for adults is typically between 12-20 breaths per minute. An increased respiratory rate above this range can indicate fluid overload.

Choice B: Increased Heart Rate

An increased heart rate, or tachycardia, is another common finding in clients with fluid overload. The heart has to work harder to pump the excess fluid throughout the body, leading to an increased heart rate. This is a compensatory mechanism to maintain adequate cardiac output and tissue perfusion. Normal resting heart rate for adults is between 60-100 beats per minute. A heart rate above this range can be indicative of fluid overload.

Choice C: Increased Blood Pressure

Fluid overload can also result in increased blood pressure, or hypertension. The excess fluid in the bloodstream increases the volume of blood that the heart has to pump, leading to higher pressure within the arteries. This can strain the cardiovascular system and lead to complications if not managed properly. Normal blood pressure is typically around 120/80 mmHg. Blood pressure readings consistently above this range can suggest fluid overload.

Choice D: Increased Hematocrit

Increased hematocrit is not typically associated with fluid overload. Hematocrit is the proportion of red blood cells in the blood. In cases of fluid overload, the hematocrit level is usually decreased due to the dilutional effect of the excess fluid. Therefore, this choice is incorrect.

Choice E: Increased Temperature

Increased temperature is not a common finding in fluid overload. Fever or elevated body temperature is more commonly associated with infections or inflammatory conditions. Fluid overload does not typically cause an increase in body temperature. Therefore, this choice is incorrect.

Choice A Reason:

Administering 0.45% NS (normal saline) at 50 mL/h is not appropriate for a client with SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion). This solution is hypotonic and can exacerbate the condition by increasing water retention and worsening hyponatremia. Therefore, this choice is not included in the plan of care.

Choice B Reason:

Obtaining daily weight is crucial for monitoring fluid balance in clients with SIADH. Daily weights help detect fluid retention or loss, which is essential for managing the condition. Accurate weight measurements can indicate changes in fluid status and guide adjustments in treatment.

Choice C Reason:

Maintaining seizure precautions is vital for clients with SIADH because severe hyponatremia can lead to neurological symptoms, including seizures. Implementing seizure precautions helps ensure the client’s safety and allows for prompt intervention if seizures occur.

Choice D Reason:

Administering 3% saline as ordered is appropriate for treating severe hyponatremia in clients with SIADH. Hypertonic saline helps increase serum sodium levels, which is critical for correcting the electrolyte imbalance. This intervention should be closely monitored to avoid rapid changes in sodium levels.

Choice E Reason:

Encouraging fluid intake is not appropriate for clients with SIADH. The condition is characterized by excessive water retention, and increasing fluid intake can worsen hyponatremia. Instead, fluid restriction is typically recommended to manage the condition effectively.
