The nurse is evaluating the fluid balance of a client who was admitted yesterday with dehydration and who has been receiving IV fluids since admission. An increase in which parameter indicates to the nurse that the client is rehydrating?

Choice A reason: Removing the nasal cannula is not appropriate as it would deprive the client of supplemental oxygen. The client's oxygen saturation is below the normal range of 95% to 100%, indicating hypoxemia.

Choice B reason:While increasing oxygen might seem appropriate, this should only be done after verifying the accuracy of the pulse oximeter reading and assessing the client’s overall condition. Automatically increasing oxygen without further assessment could delay addressing other underlying issues or lead to over-oxygenation in clients with certain conditions like COPD.

Choice C reason:The first step is to ensure the accuracy of the pulse oximeter reading by checking its placement and ruling out factors that can interfere with accurate readings, such as poor circulation, cold extremities, nail polish, or motion artifacts. This ensures that the subsequent intervention is based on reliable data.

Choice D reason: Switching to a non-rebreather mask is not necessary as it would deliver a high concentration of oxygen (up to 100%) that may be excessive for the client. A nasal cannula can deliver oxygen from 1 to 6 L/minute, depending on the client's needs.

Choice A reason: Serum potassium and sodium levels are not relevant to the assessment of the wound infection. They are electrolytes that regulate fluid balance, nerve conduction, and muscle contraction. They may be affected by dehydration, renal failure, or diuretics.

Choice B reason: Neutrophil count is the most relevant laboratory value to note before reporting the wound infection. Neutrophils are white blood cells that fight bacterial infections and inflammation. A high neutrophil count indicates an acute infection or inflammation, while a low neutrophil count indicates a compromised immune system or a chronic infection.

Choice C reason: Blood pH level is not relevant to the assessment of the wound infection. It is a measure of the acidity or alkalinity of the blood. It may be affected by respiratory or metabolic disorders, such as acidosis or alkalosis.

Choice D reason: Hematocrit is not relevant to the assessment of the wound infection. It is the percentage of red blood cells in the blood. It may be affected by anemia, dehydration, or polycythemia.
