A patient comes to the Emergency Department with inspiratory stridor, nonproductive cough, and tachypnea. What treatment do you anticipate for this patient as the priority?
Antibiotics
Sputum culture
Inhaled bronchodilator
History of illness exposure
The Correct Answer is C
Choice A reason: Antibiotics treat bacterial infections, but inspiratory stridor, cough, and tachypnea suggest acute airway obstruction, like croup or bronchospasm. Antibiotics are not immediate for these symptoms, as they address infection, not airway narrowing, making this a lower-priority treatment.
Choice B reason: Sputum culture identifies pathogens but is not urgent for inspiratory stridor, which indicates airway compromise needing immediate relief. Cultures guide long-term therapy, not acute management, making this an incorrect priority for the patient’s presentation.
Choice C reason: Inhaled bronchodilators, like albuterol, are the priority for inspiratory stridor, nonproductive cough, and tachypnea, as they relax airway smooth muscles, relieving bronchospasm or narrowing. This addresses acute airway obstruction, common in conditions like asthma or croup, making it the correct treatment.
Choice D reason: History of illness exposure informs diagnosis but delays treatment for acute airway symptoms. Inspiratory stridor requires immediate intervention to ensure airway patency, making history-taking secondary to addressing the urgent respiratory distress, thus an incorrect priority.

Correct Answer is C
Explanation
Choice A reason: Linking high potassium to kidney function risk is inaccurate; hyperkalemia primarily affects cardiac and neuromuscular function. Numbness, tingling, or weakness are direct symptoms, making this statement less relevant for patient education and incorrect.
Choice B reason: Changing IV fluids may be a treatment but doesn’t explain the issue or engage the patient. Asking to report numbness, tingling, or weakness directly addresses hyperkalemia symptoms, making this less appropriate and incorrect.
Choice C reason: High potassium (6.1 mEq/L) can cause numbness, tingling, or weakness. Instructing the patient to report these symptoms ensures early detection of worsening hyperkalemia, making this the correct, patient-centered statement for education.
Choice D reason: Palpitations may occur, but numbness, tingling, and weakness are more specific to hyperkalemia’s neuromuscular effects. “Quick beating” is less precise for heart rhythm issues, so this is incorrect compared to option c.
Correct Answer is ["A","B","C"]
Explanation
Choice A reason: Increased permeability and leakage occur at an injury site due to histamine and cytokine release, causing endothelial gaps. This allows plasma and immune cells to enter tissues, promoting inflammation and edema, making this a correct vascular change.
Choice B reason: Blood vessels initially constrict to limit bleeding, then dilate to increase blood flow, delivering immune cells and nutrients. This biphasic response (constriction followed by dilation) is a hallmark of acute injury, making this a correct vascular change.
Choice C reason: Pallor occurs from initial vasoconstriction, reducing blood flow, followed by swelling from increased permeability and fluid leakage. These are typical injury responses, reflecting vascular and tissue changes, making this a correct observation.
Choice D reason: “None of the above” is incorrect, as increased permeability, biphasic vessel response, and pallor with swelling are well-documented vascular changes at injury sites. These align with the inflammatory process, making this an invalid choice.
Choice E reason: Tightening of capillary endothelial junctions does not occur during acute injury. Junctions loosen due to inflammatory mediators, increasing permeability, not tightening, which would limit leakage, making this an incorrect vascular change.
