A nurse is caring for a client who experienced an infection at the insertion site of her intravenous catheter. Which of the following findings should the nurse expect?

A. Light-headedness when standing up:
Elevated potassium levels (hyperkalemia) can lead to muscle weakness or paralysis, cardiac dysrhythmias, and even cardiac arrest. Light-headedness when standing up is more commonly associated with orthostatic hypotension or volume depletion rather than electrolyte imbalances like hyperkalemia.

B. Weak quadriceps muscles:
Weakness in the quadriceps muscles is not typically associated with the electrolyte imbalances presented in the scenario. Hyperkalemia can cause muscle weakness, but it is not specific to the quadriceps.

C. Decreased deep tendon reflexes:
Decreased deep tendon reflexes are not typically associated with the electrolyte imbalances presented in the scenario. Hyperkalemia can lead to hyperreflexia or absent reflexes, but it is not specific to decreased deep tendon reflexes.

D. Tingling of extremities:
This is the correct answer. Hypocalcemia, indicated by the low calcium level in the scenario, can manifest with symptoms such as tingling or numbness of the extremities, muscle cramps, and tetany. Calcium plays a crucial role in nerve transmission, and low levels can lead to sensory disturbances like tingling in the extremities.

A) Increase hematocrit: Fluid overload typically results in dilutional effects on the blood, leading to a decrease in hematocrit rather than an increase. Hematocrit levels may decrease due to the relative decrease in the concentration of red blood cells in relation to plasma.

B) Increased temperature: Fluid overload is not typically associated with an increase in body temperature. While fever can occur as a result of infection, it is not a direct manifestation of fluid overload.

C) Increased heart rate: Fluid overload can lead to increased blood volume, which results in an increased workload for the heart. As a compensatory mechanism, the heart rate may increase to maintain adequate cardiac output.

D) Increased respiratory rate: Fluid overload can cause pulmonary congestion and impair gas exchange in the lungs, leading to respiratory distress. As a result, the respiratory rate may increase as the body attempts to compensate for the decreased oxygenation.

E) Increased blood pressure: Fluid overload can lead to an increase in blood volume, which results in increased pressure within the blood vessels. As a result, blood pressure may rise as the heart works harder to pump the excess fluid throughout the body.
