A client presents to the emergency department with nausea, vomiting, and diarrhea. While obtaining the history and physical assessment, the nurse discovers that the client's significant other is recovering from COVID 19. After obtaining a nasal swab to test the client for COVID 19, which action is most important for the nurse to take?

Start an IV infusion for antiviral drug to be administered for positive COVID 19 test results.

Institute droplet precautions, place client in a private room, and keep the door closed.

Counsel family members to monitor for illness symptoms for 2 weeks after last contact with patient.

Explain to the client to inform others that they may have been potentially exposed in the last 14 days.

Answer and Explanation

The Correct Answer is B

Rationale

A. Starting IV infusion for antiviral drugs is premature without confirmation of COVID-19 diagnosis. Antiviral treatment for COVID-19 is typically initiated based on positive test results and clinical assessment by the healthcare provider. It is important to wait for test results before starting specific treatment protocols.

B. Given the client's symptoms and exposure history to someone with COVID-19, it is crucial to implement droplet precautions. This includes placing the client in a private room with the door closed to minimize the risk of airborne transmission. Healthcare providers should wear appropriate personal protective equipment (PPE), including masks (N95 respirator or surgical mask), gown, gloves, and eye protection, when entering the room.

C. This action is appropriate to inform family members about potential exposure to COVID-19. Symptoms can develop up to 14 days after exposure, so monitoring for symptoms is essential. However, immediate isolation and precautions for the client are more critical at this stage.

D. While it is important for the client to inform others about potential exposure, the immediate concern is implementing isolation precautions for the client and preventing further transmission within the healthcare setting.

Correct Answer is B

Explanation

Rationale

A. Evacuation centers often accommodate a large number of people in close proximity. This can lead to increased transmission of infectious agents, including those causing diarrheal illnesses, through person- to-person contact or contaminated surfaces.

B. Hurricanes can cause flooding, which may overwhelm sewage systems and lead to contamination of drinking water sources. Consuming water contaminated by sewage can introduce pathogens that cause diarrheal diseases, such as bacteria like Escherichia coli or viruses like norovirus.

C. Flood waters can contaminate food supplies in various ways, such as direct contact with contaminated water, improper storage, or inadequate cooking or refrigeration. Consuming

contaminated food can result in diarrheal illnesses due to ingestion of pathogens like bacteria or parasites.

D. Nosocomial infections refer to infections acquired in healthcare settings. In a disaster medical area, improper infection control practices or overcrowding can contribute to nosocomial transmission of infectious agents, including those causing diarrheal diseases. However, this option is less likely in the context of a client seeking treatment for diarrhea immediately upon arrival at the disaster medical area.

Correct Answer is ["12.5"]

Explanation

To calculate the dosage of amoxicillin suspension to be administered every 8 hours, one must first determine the total daily dosage in milligrams. Since 1 gram equals 1000 milligrams, 1.5 grams is equivalent to 1500 milligrams. This total daily dosage needs to be divided into three doses, as it will be administered every 8 hours.

Therefore, each dose will be 1500 mg divided by 3, which equals 500 mg per dose. The medication bottle states that there are 200 mg of amoxicillin in every 5 mL of suspension. To find out how many mL correspond to a 500 mg dose, set up a proportion: 200 mg/5 mL = 500 mg/x mL. Solving for x gives x = (500 mg * 5 mL) / 200 mg, which equals 12.5 mL

Therefore, the nurse should administer 12.5 mL of the amoxicillin suspension every 8 hours.
