The nurse is caring for client with liver failure admitted with hepatic encephalopathy, Lactulose is ordered Q2 hours. What assessment finding should the nurse use to best evaluate therapeutic response of the medication?

A. Sodium: Sodium levels are important to monitor, but in the context of pantoprazole use, abnormal sodium levels are less commonly a direct concern. Pantoprazole primarily impacts the gastric environment rather than fluid or electrolyte balance in a way that would dramatically alter sodium levels.

B. Gastric pH: Pantoprazole works to increase gastric pH by reducing acid secretion, which is its primary therapeutic effect. A higher gastric pH is expected and beneficial in conditions like GERD or peptic ulcers.

C. Calcium: Pantoprazole, when used for extended periods, can interfere with calcium absorption, potentially leading to bone health issues like osteoporosis. However, changes in calcium levels typically do not pose an immediate or life-threatening concern unless significantly low or related to prolonged therapy. It is still something to monitor, but magnesium is a higher priority in this case.

D. Magnesium: Pantoprazole and other proton pump inhibitors (PPIs) are known to cause hypomagnesemia, especially with prolonged use. Low magnesium levels can lead to serious complications, including muscle spasms, seizures, and arrhythmias. Hypomagnesemia is a well-documented side effect of long-term PPI use, making it the most critical lab result to address.

A) Evaluation: Evaluation is the phase where the nurse assesses whether the goals or outcomes of the care plan have been met. It involves determining if the interventions provided were effective in achieving the desired outcomes. In this scenario, the nurse is still
gathering information before the action is taken, so evaluation is not the correct phase.

B) Planning: Planning is the phase in the nursing process where the nurse develops a care plan, which includes setting goals and determining interventions based on the client's needs. Although reviewing the medical record and blood glucose level is important for planning the administration of insulin, this is more about gathering data rather than forming a plan of care.

C) Implementation: Implementation refers to the actual delivery of the nursing interventions or actions. In this case, administering the insulin would be part of the implementation phase, but reviewing the medical history and obtaining a fingerstick blood glucose reading are steps taken before implementing the medication.

D) Assessment: The nurse is collecting pertinent information about the client’s condition, including reviewing the medical record and obtaining the blood glucose level. Assessment is the first step in the nursing process and involves gathering information to help guide clinical decisions.

E) Diagnosis: Diagnosis is the phase in which the nurse analyzes the assessment data to identify the client’s health problems or potential risks. While the nurse is collecting data, the diagnosis comes after the assessment phase, when the nurse has enough information to make a clinical judgment about the client's health status.
