A nurse in a provider's clinic is assessing a client who has rheumatoid arthritis and is prescribed methotrexate. Which action should the nurse take first when the client reports bleeding gums?

A.Depressed mood and psychological distress are common in clients with chronic autoimmune diseases due to physical limitations and the unpredictable nature of flares. While mental health is a significant concern that requires screening and support, it does not indicate acute organ-threatening pathology. The nurse should address this with counseling and potential pharmacotherapy, but it is not the most immediate threat to life.

B.A facial rash, particularly the characteristic malar "butterfly" rash, is a classic diagnostic hallmark of systemic lupus erythematosus resulting from cutaneous inflammation. While it indicates active disease or photosensitivity, it is usually a superficial manifestation that does not represent internal organ failure. Skin changes are common in SLE and generally managed with topical steroids and ultraviolet light protection rather than emergency intervention.

C.Weight loss can occur during SLE flares due to systemic inflammation, decreased appetite, or metabolic changes associated with the autoimmune process. While significant weight changes require nutritional assessment and monitoring, they usually represent a chronic progression rather than an acute clinical emergency. The nurse should document this finding and assess for other signs of systemic involvement, but it is not the highest priority.

D.Decreased urine output is highly concerning in SLE because it may signal the development of lupus nephritis, a severe complication where immune complexes damage the renal glomeruli. This can rapidly progress to acute kidney injury or chronic renal failure if not treated aggressively with immunosuppressants. Because renal involvement is a leading cause of morbidity and mortality in SLE, this symptom demands immediate diagnostic follow-up.

A.Calling the laboratory to verify results is only indicated when a value is critically high, critically low, or clinically inconsistent with the patient's physical presentation. A potassium level of 3.5 mEq/L is at the low end of the normal physiological range (3.5 to 5.0 mEq/L) and does not constitute a laboratory emergency. Verification would unnecessarily delay the administration of needed electrolyte replacement.

B.A serum potassium level of 3.5 mEq/L is at the minimum threshold of the normal reference range. Since the client is receiving furosemide, a loop diuretic known to cause potassium depletion through renal excretion, administering the prescribed potassium chloride is appropriate to maintain normokalemia and prevent hypokalemia. The nurse should proceed with the administration to counteract the expected electrolyte losses associated with diuretic therapy.

C.Holding the dose and notifying the provider is not required because the potassium level is within the normal range and the medication is indicated to prevent deficiency. Notifying the provider for a normal lab value is an inefficient use of clinical communication and may lead to the patient becoming hypokalemic. The nurse should only hold the dose if the potassium level were significantly elevated (hyperkalemia).

D.Holding the dose and documenting its omission without a clinical justification or provider's order is a violation of the standards of nursing practice. Documentation of a withheld medication must include a valid physiological reason, such as an out-of-range lab value. In this case, withholding the medication puts the patient at risk for cardiac dysrhythmias and muscle weakness as the loop diuretic continues to deplete potassium stores.
