A charge nurse is reviewing guidelines for initiating airborne precautions.
Which of the following patients should the nurse identify as requiring airborne precautions?
A patient who has streptococcal pharyngitis
A patient who has scabies
A patient who has measles
A patient who has pertussis
The Correct Answer is C
Choice A rationale
Streptococcal pharyngitis, also known as strep throat, is a bacterial infection that causes inflammation and pain in the throat. This condition is spread through respiratory droplets, not through the air, and does not require airborne precautions.
Choice B rationale
Scabies is caused by a mite infestation, not an airborne pathogen. It is spread through direct skin-to-skin contact and does not require airborne precautions.
Choice C rationale
Measles is a highly contagious virus that lives in the nose and throat mucus of an infected person. It can spread to others through coughing and sneezing, and the measles virus can live for up to two hours in an airspace where the infected person coughed or sneezed. Therefore, a patient with measles requires airborne precautions.
Choice D rationale
Pertussis, also known as whooping cough, is a highly contagious respiratory disease caused by the bacterium Bordetella pertussis. It spreads through close contact with respiratory droplets when an infected person coughs or sneezes. It is typically managed with droplet precautions, not airborne precautions.

Correct Answer is D
Explanation
Choice A rationale
The shoulder is not the correct fetal presentation in this case. The shoulder presentation, also known as a transverse lie, occurs when the fetus is positioned horizontally in the uterus, and the shoulder is the presenting part. This is not the case in an RSA (Right Sacrum Anterior) position, which indicates a breech presentation.
Choice B rationale
The vertex presentation, also known as a cephalic presentation, occurs when the fetus is positioned head down in the uterus. However, in an RSA position, the fetus is in a breech presentation, not a vertex presentation.
Choice C rationale
The mentum (face) presentation is a rare type of fetal presentation where the neck of the fetus is hyperextended, and the face presents at the cervix. This is not the case in an RSA position, which indicates a breech presentation.
Choice D rationale
In an RSA (Right Sacrum Anterior) position, the fetus is in a breech presentation. This means that the buttocks or feet of the fetus are positioned to enter the birth canal first. Therefore, the nurse should document a breech presentation in the patient’s medical record.
Correct Answer is ["120"]
Explanation
The correct answer is 120 gtt/min.
Step 1 is to convert the infusion rate from mL/hr to mL/min: 120 mL/hr ÷ 60 min/hr = 2 mL/min.
Step 2 is to multiply the mL/min rate by the drop factor to find the gtt/min rate: 2 mL/min × 60 gtt/mL = 120 gtt/min.
