Final answer:
The dose of the loop diuretic should be held and the physician notified if the patient's potassium level is 1.5 mEq/L as this indicates severe hypokalemia, which can be exacerbated by the diuretic and potentially lead to life-threatening complications.
Step-by-step explanation:
The correct direct answer to the question is B:
An explanation for this is required due to the potential seriousness of the condition. Loop diuretics promote the loss of potassium through increased urination, and administering the medication to a patient with an already low potassium level may cause further depletion, possibly leading to severe hypokalemia. Hypokalemia can result in life-threatening issues such as cardiac arrhythmias, muscle weakness, or paralysis. Therefore, it would be essential to hold the loop diuretic and notify the physician immediately for further assessment and orders, which might include supplementation or alteration of the medication regimen.
In contrast, the calcium level of 9 mg/L falls within the normal range, as does the sodium level of 144 mEq/L. The blood pressure reading of 102/78 might be slightly low for some individuals but would not typically be an indication to hold a loop diuretic unless the patient has other symptoms or specific instructions from the healthcare provider.
It is critical for healthcare providers to carefully monitor electrolyte levels, particularly potassium, in patients receiving loop diuretics to prevent complications associated with electrolyte imbalances. Prompt communication with healthcare team members is vital when abnormal values are encountered to ensure patient safety.
