A nurse is reinforcing education about Infection prevention to a group of clients at a community center. What information should the nurse Include in the teaching?

Clean a pet's litter box once a week.

Take antibiotics when you have a cough or cold virus.

Use separate cutting boards for meat and vegetables.

Allow frozen foods to thaw on the countertop.

Answer and Explanation

The Correct Answer is C

Infection prevention education in the community focuses on reducing exposure to infectious organisms through proper hygiene, safe food handling, and environmental cleanliness. Many foodborne illnesses are caused by cross-contamination, where bacteria from raw animal products are transferred to ready-to-eat foods. Teaching safe kitchen practices is essential to reduce gastrointestinal infections and other preventable illnesses. Nurses emphasize evidence-based strategies that interrupt transmission routes of pathogens.

Rationale:
A. Cleaning a pet’s litter box once a week is incorrect because litter boxes should be cleaned daily to reduce exposure to pathogens such as Toxoplasma gondii. Delayed cleaning increases the risk of environmental contamination and transmission of zoonotic infections. More frequent hygiene practices are required for effective infection prevention.

B. Taking antibiotics for viral illnesses such as coughs or colds is inappropriate because antibiotics are ineffective against viruses. Overuse contributes to antimicrobial resistance and does not shorten viral illness duration. Viral infections require supportive care rather than antibiotic therapy.

C. Using separate cutting boards for raw meat and vegetables helps prevent cross-contamination of pathogens such as Salmonella and E. coli. Raw meat can harbor bacteria that may spread to ready-to-eat foods if shared surfaces are used. This is a key food safety practice in infection prevention education.

D. Allowing frozen foods to thaw on the countertop increases the risk of bacterial growth because food may enter the “danger zone” temperature range where microorganisms multiply rapidly. Safe thawing methods include refrigeration, cold water, or microwave thawing. Improper thawing practices significantly increase foodborne illness risk.

Correct Answer is D

Explanation

Postoperative clients require close monitoring for early signs of infection, especially within the first few days after surgery when surgical sites are most vulnerable. Infection can develop due to bacterial contamination, impaired tissue healing, or compromised immunity. Common indicators include systemic inflammatory responses such as fever, leukocytosis, and localized signs at the incision site. Nurses must differentiate normal postoperative changes from findings that suggest infection to ensure timely intervention.

Rationale:
A. A temperature of 37.2°C (99.0°F) is within normal or low-grade postoperative range and does not indicate infection. Mild temperature elevations can occur after surgery due to atelectasis or the inflammatory healing process. It is not a reliable indicator of infection on its own.

B. Increased urinary output is not associated with postoperative infection. In fact, infection or sepsis may initially present with decreased urine output due to poor perfusion. Increased output is more likely related to fluid administration or improved renal perfusion.

C. A pain rating of 4/10 is expected in a postoperative client and is not specific for infection. Postoperative pain typically decreases gradually with healing. Infection-related pain is often worsening, localized, and associated with other inflammatory signs rather than a moderate stable pain score.

D. An elevated WBC count is a key indicator of infection because it reflects the body’s immune response to invading pathogens. In a client who is 2 days post abdominal surgery, leukocytosis may suggest developing surgical site infection or intra-abdominal infection. In conditions involving postoperative monitoring such as Postoperative infection, elevated WBCs warrant further assessment and possible intervention.

A. "We can turn the oxygen up to 10 when he has trouble breathing." B. "We will frequently check the top of his ears for sores." C. "We will need to remove the nasal cannula when he is eating." D. "We can use petroleum jelly to keep his nares moist."

Correct Answer is B

Explanation

Home oxygen therapy via nasal cannula requires careful safety practices and skin integrity monitoring to prevent complications associated with prolonged oxygen delivery. Oxygen tubing can create continuous pressure on bony prominences such as the ears and cheeks, leading to skin breakdown. Proper education also includes safe oxygen flow settings, avoidance of flammable substances, and maintenance of nasal and skin moisture using appropriate water-based products. Family members must demonstrate understanding of both safety precautions and device care.

Rationale:
A. Increasing oxygen flow arbitrarily to “10” is unsafe because oxygen must be administered at the prescribed rate to avoid complications such as oxygen toxicity and CO₂ retention in susceptible clients. In a client receiving Oxygen therapy, flow rates should only be adjusted based on provider orders. Unregulated increases can lead to respiratory depression or oxygen-related injury.

B. Checking the tops of the ears for sores indicates correct understanding because nasal cannula tubing can cause pressure injury over time. Regular assessment helps detect early skin breakdown and allows for repositioning or padding to prevent ulcer formation. This is an important preventive measure in long-term oxygen therapy.

C. Removing the nasal cannula during meals is not necessary and may be harmful if the client requires continuous oxygen therapy. Oxygen delivery should be maintained unless otherwise prescribed, even during eating or drinking. Interrupting oxygen therapy can lead to hypoxemia in clients with respiratory compromise.

D. Using petroleum jelly is unsafe because it is oil-based and flammable in the presence of oxygen, increasing fire risk. Water-based lubricants should be used instead to moisten nasal passages. Fire safety is a critical teaching point in home oxygen therapy.
