A nurse is teaching a prenatal class about infection prevention at a community center.
Which of the following statements by a client indicates an understanding of the teaching?
"I can visit my nephew who has chickenpox 5 days after the sores have crusted."
"I should take antibiotics when I have a virus."
"I should wash my hands for 10 seconds with hot water after working in the garden."
"I can clean my cat's litter box during my pregnancy."
The Correct Answer is A
A. Correct. Chickenpox is contagious until the sores have crusted over, which generally takes about 5-7 days. Visiting after this period reduces the risk of infection.
B. Incorrect. Antibiotics are not effective against viruses; they treat bacterial infections.
C. Incorrect. Handwashing should be done with soap and water for at least 20 seconds, not 10 seconds, to effectively remove germs.
D. Incorrect. Cleaning a cat's litter box during pregnancy is not recommended due to the risk of toxoplasmosis, a parasitic infection.

Correct Answer is C
Explanation
A. Incorrect. While maintaining eye contact during feedings is generally beneficial for bonding, it's not a specific intervention for managing neonatal abstinence syndrome.
B. Incorrect. Swaddling a newborn with extended legs might be uncomfortable, as newborns with neonatal abstinence syndrome can experience increased muscle tone and jitteriness.
C. Correct. Newborns with neonatal abstinence syndrome can be hypersensitive to stimuli, including noise. Minimizing noise in the environment helps reduce stress and overstimulation.
D. Incorrect. Naloxone is not typically administered to newborns with neonatal abstinence syndrome. The syndrome is managed through supportive care, gradually reducing exposure to the substance.
Correct Answer is B
Explanation
Choice A rationale:
Changing the inner cannula on a tracheostomy is within the legal scope of practice for registered nurses. Nurses are trained to perform tracheostomy care, including changing the inner cannula. This procedure is within the nursing scope of practice and does not require a physician's intervention.
Choice B rationale:
Inserting a tunneled central venous catheter (such as a Hickman line) is a specialized procedure that generally falls under the scope of practice for advanced practice nurses (such as nurse practitioners or clinical nurse specialists) or physicians. RNs typically do not have the required training or authority to perform this invasive procedure.
Choice C rationale:
Irrigation of an external ear canal is within the legal scope of practice for registered nurses. Ear irrigation is a common nursing procedure used to remove impacted cerumen (earwax) and foreign bodies from the ear canal. Nurses are trained to perform this procedure safely and effectively.
Choice D rationale:
Administering blood products, including platelet transfusions, is within the legal scope of practice for an RN. RNs are responsible for preparing, verifying, and administering blood products according to institutional policies and procedures. This includes monitoring the patient during and after the transfusion for any adverse reactions.
