A nurse is preparing to administer levothyroxine 50 mcg to a client. Available is levothyroxine 0.025 mg/tablet. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Rationale:

• Hypoxia: Hypoxia occurs in both epiglottitis and RSV due to airway obstruction or lower respiratory involvement. In epiglottitis, airway swelling can limit oxygen intake, whereas in RSV, lower airway inflammation and bronchiolitis cause oxygen desaturation. Streptococcal pharyngitis typically does not impair oxygenation.

• Fever: Fever is a nonspecific finding seen in epiglottitis, RSV, and streptococcal pharyngitis. Infection-induced inflammation and immune response in all three conditions cause elevated temperatures. The degree and onset of fever can vary among the conditions.

• Tachypnea: Tachypnea is a compensatory response to hypoxia and airway compromise. It is commonly observed in epiglottitis due to upper airway obstruction and in RSV due to bronchiolar inflammation. It is usually absent in isolated streptococcal pharyngitis.

• Drooling: Drooling is a hallmark sign of epiglottitis due to painful swallowing and airway obstruction. It is not typical in RSV or streptococcal pharyngitis. Presence of drooling indicates urgent airway assessment.

• Exudate on pharynx: Exudative pharyngitis is characteristic of streptococcal infections. It is rarely seen in epiglottitis and RSV. White or yellow exudates on the tonsils help differentiate bacterial pharyngitis from viral or upper airway conditions.

• Wheezing upon auscultation: Wheezing is associated with lower airway involvement, commonly seen in RSV bronchiolitis. It is not typically present in epiglottitis or streptococcal pharyngitis. Wheezing reflects bronchospasm or airway inflammation.

A. Headache: Headache is not an expected finding during cardiac catheterization. If it occurs, it may indicate an unrelated issue such as anxiety, dehydration, or reaction to contrast dye, but it is not typical of the procedure itself.

B. Numbness and tingling of the extremities: Numbness and tingling are not expected during cardiac catheterization. These symptoms could suggest a complication such as nerve compression, impaired circulation, or allergic reaction, requiring immediate evaluation.

C. Increased salivation: Increased salivation is not associated with cardiac catheterization. This finding may be linked to oral stimulation or nausea, but it is not a normal response to the procedure.

D. Sensation of skin warmth: Clients often report a sensation of warmth or flushing during the injection of contrast dye used in cardiac catheterization. This response is expected and temporary, resulting from vasodilation and the chemical properties of the contrast medium.
