The nurse is developing a teaching plan for a client with acute gastritis caused by drinking contaminated water. The nurse should emphasize the need to report the onset of which problem?

Choice A rationale
Monitoring leukocytes, neutrophils, and thyroxine is not the most crucial for a patient with end-stage renal disease (ESRD). While these lab values can provide information about the patient’s immune function and thyroid function, they do not directly relate to the patient’s renal function.
Choice B rationale
Monitoring serum potassium, calcium, and phosphorus levels is crucial for a patient with ESRD. These electrolytes are typically excreted by the kidneys, and their levels can become imbalanced in patients with ESRD. Imbalances can lead to serious complications, such as cardiac arrhythmias and bone disease.
Choice C rationale
Monitoring erythrocytes, hemoglobin, and hematocrit is important for a patient with ESRD, as these patients often develop anemia due to decreased erythropoietin production by the kidneys. However, these are not the only lab values that should be monitored in these patients.
Choice D rationale

Monitoring blood pressure, heart rate, and temperature is important for all patients, but these are not specific to patients with ESRD. Patients with ESRD are at risk for electrolyte imbalances, which can affect cardiac function, making monitoring of serum potassium, calcium, and phosphorus levels more crucial.

Choice A rationale
Comparing muscle strength bilaterally is not the most important intervention in this situation. While muscle weakness can be a symptom of hyperkalemia, it is not the most immediate concern. Hyperkalemia can lead to life-threatening cardiac dysrhythmias, which is a more immediate threat to the patient’s life.

Choice B rationale

Observing the color and amount of urine can provide information about the patient’s renal function, which is important in the regulation of potassium. However, this is not the most immediate concern when a patient’s serum potassium level is dangerously high.

Choice C rationale
Determining the apical pulse rate and rhythm is the most important intervention. Hyperkalemia can cause cardiac dysrhythmias, so the nurse should immediately assess the patient’s heart rate and rhythm. The nurse should also place the patient on a cardiac monitor, if not already done, and notify the healthcare provider immediately.

Choice D rationale
Assessing the strength of deep tendon reflexes can provide information about neuromuscular function, which can be affected by hyperkalemia. However, this is not the most immediate concern. The nurse’s priority is to assess and monitor for life-threatening cardiac dysrhythmias.
