A nurse is reviewing the EKG strip of a client who has prolonged vomiting. Which of the following abnormalities on the client's EKG should the nurse interpret as a sign of hypokalemia?

A. Increase hematocrit: Fluid overload typically leads to hemodilution, resulting in a decrease in hematocrit rather than an increase. Therefore, an increase in hematocrit would not be expected in a client with fluid overload.
B. Increased temperature: Fluid overload is not typically associated with an increased body temperature. Instead, fever may indicate an infection or another underlying cause. Therefore, an increased temperature would not be a typical finding in a client with fluid overload.
C. Increased heart rate: Fluid overload can lead to an increased heart rate as the body attempts to maintain adequate cardiac output in the presence of excess fluid volume. An elevated heart rate is a compensatory mechanism to maintain tissue perfusion despite the increased workload on the heart.
D. Increased respiratory rate: Fluid overload can cause pulmonary congestion, leading to increased respiratory effort and a higher respiratory rate as the body attempts to compensate for decreased gas exchange efficiency. An increased respiratory rate helps to improve oxygenation and remove excess carbon dioxide from the body.
E. Increased blood pressure: Fluid overload often leads to increased blood pressure due to the increased volume of circulating blood, which can strain the cardiovascular system. Elevated blood pressure is a common manifestation of fluid overload and reflects the increased workload on the heart and blood vessels.

A. Notify the client's provider: This option might be considered if there are signs of postpartum hemorrhage, such as excessive bleeding, signs of shock, or a boggy uterus that does not respond to massage. However, in this scenario, the fundus is midline and firm, which indicates appropriate uterine contraction. Therefore, notifying the provider at this point may not be necessary.
B. Encourage the client to empty her bladder: Encouraging the client to empty her bladder is always important in the postpartum period, as a full bladder can impede uterine contraction. However, the presence of lochia rubra and small clots along with a midline and firm fundus suggests that uterine involution is progressing well. While encouraging the client to empty her bladder is appropriate, it may not be the priority in this situation.
C. Increase the frequency of fundal massage immediately: Fundal massage is typically performed to promote uterine involution and prevent postpartum hemorrhage. However, in this scenario, the fundus is already midline and firm, indicating adequate contraction. Increasing the frequency of fundal massage unnecessarily could cause discomfort to the client and is not indicated based on the current assessment findings.
D. Document the findings and continue to monitor the client: This is the most appropriate action at this time. The presence of lochia rubra and small clots along with a midline and firm fundus suggests that the uterus is involuting properly. Documenting the findings allows for accurate documentation of the client's condition and continued monitoring for any changes or developments. If the client's condition changes or if there are signs of postpartum hemorrhage, further action, such as notifying the provider, can be taken.
