Which condition may the patient have when reporting flushing, itching, hives, anxiety, and tongue swelling after taking an antibiotic?

This question evaluates the management of side effects resulting from loop diuretic therapy. It requires assessing clinical signs of hypovolemia and electrolyte imbalance (normal potassium 3.5 to 5.0 mEq/L) to implement safety interventions that prevent injury while balancing fluid removal and hemodynamic stability.

Choice A rationale

While potassium supplementation is needed for a level of 3.2 mEq/L, administration requires a provider order to ensure safety and correct dosing. Independent administration of medications is outside of nursing scope and could lead to cardiac toxicity.

Choice B rationale

The patient's blood pressure of 90/60 mm Hg and reported dizziness indicate symptomatic orthostatic hypotension. Implementing fall precautions is the immediate priority to ensure patient safety while the nurse continues to monitor hemodynamic status and notifies the provider for further orders.

Choice C rationale

Encouraging increased fluid intake in a patient receiving diuretics for edema is counterproductive to the therapeutic goal of fluid removal. The focus should be on managing the postural hypotension through safety measures and titration rather than reversing the diuretic effect.

Choice D rationale

While withholding the medication might be appropriate given the hypotension and hypokalemia, the nursing priority is first to ensure the patient's immediate safety through fall prevention, followed promptly by reporting the clinical findings to the provider for a definitive medication plan.

This question tests clinical judgment regarding life-threatening adverse reactions to vancomycin. It requires identifying the signs of an anaphylactic or severe infusion-related reaction, which necessitates immediate intervention to maintain the patient's airway, breathing, and circulation, as these symptoms indicate critical physiological instability.

Choice A rationale

Phlebitis is a localized inflammatory reaction of the vein wall. While it requires assessment and site rotation to prevent further tissue damage, it is a localized complication and does not represent a life-threatening systemic emergency.

Choice B rationale

Flushing, hypotension, and wheezing are cardinal signs of an anaphylactic reaction. These systemic symptoms indicate severe bronchospasm and cardiovascular collapse, requiring immediate cessation of the infusion, administration of epinephrine, and urgent medical management to prevent patient mortality.

Choice C rationale

Mild tinnitus is a known side effect related to vancomycin's potential ototoxicity, which is usually dose-related and progressive. While it warrants monitoring and potential dose adjustment, it does not represent an immediate systemic emergency that requires emergency intervention.

Choice D rationale

Mild myalgia and vertigo can occur following vancomycin administration but are not indicative of an immediate, life-threatening crisis. They require monitoring and documentation, but the patient remains hemodynamically stable, making this a secondary priority compared to anaphylaxis.
