Final answer:
The most important lab results to monitor in a patient with hypovolemic shock receiving lactated Ringer's are serum potassium, sodium, and pH levels to check for electrolyte imbalances and ensure homeostasis. Hemoglobin and hematocrit are also important to assess overall blood volume and oxygen delivery. The correct option is C.
Step-by-step explanation:
A patient with hypovolemic shock receiving lactated Ringer's solution for fluid replacement needs close monitoring of several laboratory results due to the critical balance of fluids and electrolytes necessary for homeostasis. During this therapy, the most important laboratory result to monitor is serum potassium, serum sodium, and serum pH levels due to the risk of electrolyte imbalances which can be life-threatening.
However, it is also crucial to track hemoglobin (Hgb) and hematocrit (Hct) levels to ensure adequate oxygen-carrying capacity and overall blood concentration. Acid-base imbalances indicated by changes in serum pH can suggest underlying metabolic issues that need correction.
Given the patient is receiving an isotonic solution like lactated Ringer's, which has similar electrolyte concentrations to blood, avoiding drastic shifts in osmolarity that could cause cellular damage is essential.
