A nurse is assisting with triage for group of clients following a mass casualty incident. Which of the following actions should the nurse take?

A) Beefy, red tongue: The beefy, red tongue is typically associated with scarlet fever, a bacterial infection caused by group A Streptococcus. This condition can lead to a red, "strawberry" tongue, often accompanied by a rash. While measles can involve a variety of symptoms, including a red rash, conjunctivitis, and cough, the beefy red tongue is not characteristic of measles. In measles, the more notable symptoms are a high fever, cough, runny nose, and the development of Koplik spots inside the mouth.

B) Paroxysmal cough: Paroxysmal cough, which is a sudden, severe, and uncontrollable cough often followed by a "whooping" sound, is more characteristic of pertussis (whooping cough). While a cough is indeed present with measles, it is generally not paroxysmal. In measles, the cough is more persistent and associated with other typical symptoms such as fever and a characteristic rash. The coughing in measles may also be dry and harsh but does not tend to occur in violent, paroxysmal episodes like those seen in pertussis.

C) Peeling of the hands and feet: Peeling of the skin, particularly of the hands and feet, is more commonly observed in conditions such as scarlet fever, Kawasaki disease, or after a viral infection like hand-foot-and-mouth disease. It is not a classic finding of measles. In measles, the skin rash usually starts as maculopapular spots on the face and spreads down the body. While some skin sloughing can occur after the rash resolves, especially in severe cases, it is not the characteristic sign of measles, and it is not typically seen on the hands and feet.

D) Fever: Fever is one of the earliest and most prominent symptoms of measles. It typically appears about 2-4 days before the characteristic measles rash. The fever in measles can be quite high, often exceeding 104°F (40°C), and is associated with other symptoms such as cough, conjunctivitis, and photophobia. The fever usually persists for several days, and it is one of the critical signs that lead to the diagnosis of measles, particularly when combined with the characteristic rash and other respiratory symptoms.

A) Time: The time of administration is an important factor to clarify. The prescription specifies erythromycin 500mg four times per day, but it does not specify the exact times the medication should be administered. The nurse should clarify the specific times to ensure the medication is given at proper intervals, especially considering the potential for drug interactions and the timing of meals, which may impact absorption.

B) Dosage: The dosage of 500mg is specified clearly in the prescription. There is no indication that the dosage is incorrect or needs clarification. Erythromycin 500mg four times per day is a standard dose for certain infections, so no issues are apparent with the dosage itself.

C) Route: The route of administration (oral, intravenous, etc.) is not specified in the question but is typically understood unless otherwise stated. However, in the context of erythromycin, the most common route is oral. Unless there’s uncertainty about the route, it does not need clarification.

D) Medication: The medication is clearly identified as erythromycin, which is a known antibiotic. There is no ambiguity in the medication prescribed, so there is no need for clarification in this regard. The focus should be on confirming the time of administration.
