A patient arrives at the emergency department exhibiting symptoms of nausea, vomiting, and diarrhea.
The nurse learns during the physical assessment that the patient’s partner is recovering from COVID-19. After taking a nasal swab to test the patient for COVID-19, what is the most crucial action for the nurse to take?

Advise family members to monitor for symptoms of illness for two weeks after their last contact with the patient.

Implement droplet precautions, place the patient in a private room, and keep the door closed.

Inform the patient to notify others that they may have been potentially exposed in the past 14 days.

Initiate an IV infusion for the administration of an antiviral drug in case of a positive COVID-19 test result.

Answer and Explanation

The Correct Answer is B

Choice A rationale

While advising family members to monitor for symptoms of illness is important, it’s not the most crucial action for the nurse to take immediately after testing the patient for COVID-194.

Choice B rationale

Implementing droplet precautions, placing the patient in a private room, and keeping the door closed is the most crucial action. This helps prevent the potential spread of COVID-19 to other patients and healthcare workers.

Choice C rationale

Informing the patient to notify others about potential exposure is important, but it’s not the most crucial action immediately after testing.

Choice D rationale

Initiating an IV infusion for the administration of an antiviral drug is not the most crucial action. Antiviral medication is typically administered after a positive test result, not before.

Correct Answer is B

Explanation

Choice A rationale

Hematocrit is a measure of the proportion of red blood cells in the blood. While it can be affected by various conditions, it is not the most relevant lab value to check when purulent drainage is noticed at a postoperative patient’s dressing site.

Choice B rationale

Neutrophil count is a measure of the number of neutrophils, a type of white blood cell, in the blood. An elevated neutrophil count can indicate an infection, making it the most relevant lab value to check in this scenario.

Choice C rationale

Platelet count is a measure of the number of platelets in the blood. While platelets play a crucial role in blood clotting, they are not directly related to infection and therefore not the most relevant lab value to check in this scenario.

Choice D rationale

Serum sodium level is a measure of the amount of sodium in the blood. While it can be affected by various conditions, it is not the most relevant lab value to check when purulent drainage is noticed at a postoperative patient’s dressing site.

Correct Answer is ["21"]

Explanation

Step 1 is: Convert 12 hours into minutes. 12 hours × 60 minutes/hour = 720 minutes.

Step 2 is: Calculate the infusion rate. (1000 mL ÷ 720 minutes) × 15 gtt/mL = 20.83 gtt/min. Therefore, the infusion rate should be approximately 21 gtt/min when rounded to the nearest whole number.
