A nurse is evaluating teaching about infection control with the caregiver of a school-age child who has rubella.
Which of the following statements by the caregiver indicates an understanding of the teaching?
"I will take my child for a walk in the hallway today.”.
"I will contact my pregnant friend who visited my child a day before the rash appeared.”.
"I won't send my child to school for seven days after the rash disappears.”.
"I will keep my child's door closed when I visit.”. .
The Correct Answer is C
Choice A rationale
Taking the child for a walk in the hallway increases exposure to others and the risk of rubella transmission. Rubella is a contagious viral illness requiring droplet isolation precautions to prevent spreading. Walking in public spaces breaches infection control standards. Rubella symptoms include fever, rash, and swollen lymph nodes. Maintaining isolation reduces the risk of secondary infections, particularly in vulnerable populations like pregnant individuals, for whom rubella poses significant teratogenic risks.
Choice B rationale
Contacting a pregnant friend who visited before the rash appeared disregards rubella's incubation and transmission periods. Rubella is communicable 7 days before and up to 7 days after rash onset. Exposing pregnant individuals to rubella increases the risk of congenital rubella syndrome, leading to severe fetal complications. Understanding rubella’s contagious timeline ensures caregivers take necessary precautions to protect at-risk populations, emphasizing avoiding direct contact during infectious periods.
Choice C rationale
Keeping the child home for 7 days after rash disappearance adheres to rubella isolation guidelines. Rubella remains transmissible during and after rash presence, necessitating extended isolation to prevent community spread. Droplet precautions limit viral dissemination, particularly crucial around immunocompromised and pregnant individuals. Educating caregivers about prolonged isolation promotes effective infection control and minimizes public health risks associated with rubella outbreaks.
Choice D rationale
Keeping the child’s door closed when visiting does not adequately prevent rubella transmission. Droplet isolation requires mask use, restricted visitor access, and proper room ventilation. Closing the door alone fails to control airborne particles expelled during coughing or sneezing. Infection control measures prioritize reducing respiratory droplet spread, safeguarding household members and visitors from acquiring rubella.

Correct Answer is A
Explanation
Choice A rationale
Allowing medications to flow by gravity ensures gradual administration, minimizing the risk of mucosal irritation and preventing excessive pressure or leakage in the nasogastric tube.
Choice B rationale
Crushing sustained-release tablets alters their pharmacokinetics, leading to uncontrolled drug release and increased risk of toxicity or subtherapeutic effects. Sustained-release formulations must remain intact.
Choice C rationale
Using 2 mL sterile water is inadequate for flushing a nasogastric tube post-medication; recommended flushing volumes typically range between 10-15 mL for effective clearance.
Choice D rationale
Mixing medications together may result in chemical interactions and altered bioavailability. Administering each medication individually is essential to maintaining integrity and therapeutic efficacy.
Correct Answer is A
Explanation
Choice A rationale
Applying an ice collar provides localized cooling, reducing postoperative swelling and discomfort. The cold restricts blood flow and inflammation at the surgical site, improving healing. Ice therapy minimizes pain through nerve desensitization, aiding recovery and child comfort. This method aligns with evidence-based practices for managing postoperative symptoms.
Choice B rationale
Providing cherry fruit juice is inappropriate due to its acidic content, which may irritate the tonsillectomy site, delaying healing. Acidic beverages can exacerbate pain and interfere with tissue repair. Postoperative diets should prioritize non-acidic, soothing liquids for optimal recovery.
Choice C rationale
Encouraging straw use increases suction force in the mouth, which can disrupt blood clot formation and trigger bleeding at the surgical site. Using cups or spoons for fluid intake eliminates suction risks, promoting clot stability and healing post-tonsillectomy.
Choice D rationale
Coughing and deep breathing are contraindicated due to potential strain on the tonsillectomy site, increasing risk of bleeding or delayed recovery. Such actions elevate pressure in the surgical area, compromising clot stability. Rest and gentle care ensure smoother postoperative healing.
