A nurse on a medical unit is reviewing the laboratory reports for a client. Which of the following laboratory values is the priority to report to the provider?

A) Increased blood pressure:
Fluid overload results in an increased volume of fluid in the vascular system, leading to higher blood pressure. The excess volume places additional strain on the heart and blood vessels, causing an elevation in systolic and diastolic pressure. The nurse should expect to find elevated blood pressure in a client experiencing fluid overload due to the increased blood volume.

B) Increased hematocrit:
Hematocrit is the proportion of red blood cells in the blood, and it tends to decrease, not increase, during fluid overload. This is because the excess fluid in the bloodstream dilutes the blood, lowering the hematocrit level. Therefore, an increase in hematocrit would not be expected in fluid overload.

C) Increased respiratory rate:
Fluid overload, particularly when it affects the lungs (as seen in conditions like congestive heart failure), can cause respiratory distress. The accumulation of fluid in the lungs impairs gas exchange, leading to hypoxia and the body compensating by increasing the respiratory rate. This response helps increase oxygenation and expel carbon dioxide, so the nurse should expect to see an increased respiratory rate.

D) Increased heart rate:
An elevated heart rate, or tachycardia, is a compensatory response to fluid overload. The heart tries to pump the excess fluid through the circulatory system, which increases the heart's workload. As a result, the heart rate increases in an attempt to maintain adequate cardiac output despite the increased blood volume.

E) Increased temperature:
An elevated body temperature is not typically associated with fluid overload. In fact, fluid overload is more likely to present with normal or slightly lower body temperature, especially if there is no infection or inflammatory process present. If there is an increase in temperature, the nurse should consider other possible causes, such as infection or inflammatory conditions.

A) Notify the facility’s ethics committee:
While it may be relevant to involve an ethics committee in certain complex situations, such as when there are concerns about patient autonomy or ethical decision-making, the refusal of a medication by a client is generally a standard issue that does not immediately require ethics consultation.

B) Return the opened medication in the medication cart:
Returning an opened unit-dose medication to the cart is not appropriate. Once a unit-dose medication is opened, it cannot be reused due to safety concerns (e.g., contamination, dosage errors). The opened medication should be disposed of properly according to the facility's policies for medication handling and disposal.

C) Report the incident to the provider:
The provider should be notified when a client refuses medication, especially if the medication is essential for the client’s treatment or health condition. It is important for the nurse to document the refusal and inform the provider so that appropriate follow-up can be arranged, including possible reassessment of the treatment plan, alternative medications, or further education for the client.

D) Fill out an incident report:
An incident report is typically completed for situations that involve safety issues, errors, or accidents that may affect patient safety or quality of care. While refusal of medication is an important event, it does not generally require an incident report unless it involves an unusual or dangerous situation, such as a medication error or patient harm.
