A home health nurse is assisting in the care of a client.
Amount of time washing hands
Use of cutting board
Defrosting of frozen foods
Leftover storage time in refrigerator
Refrigerator temperature
Time leftovers sit unrefrigerated on countertop
Correct Answer : A,B,C,D
A. Amount of time washing hands: The client increased handwashing time to 15 seconds, which meets the CDC’s recommended minimum for effective hand hygiene when preparing food.
B. Use of cutting board: The client now uses separate cutting boards for raw meats and raw vegetables, which helps prevent cross-contamination and foodborne illness.
C. Defrosting of frozen foods: Defrosting foods in the refrigerator is a safe method that prevents bacterial growth, unlike leaving food on the countertop.
D. Leftover storage time in refrigerator: Storing leftovers in the refrigerator for a maximum of 2 days (or 7 days initially) demonstrates proper food handling to prevent spoilage and bacterial growth. This aligns with recommended guidelines.
E. Refrigerator temperature: Although the temperature has improved (now 5.6°C instead of 6.7°C), the ideal refrigerator temperature should be 4°C (40°F) or lower for optimal food safety.
F. Time leftovers sit unrefrigerated on countertop: Leaving leftovers at room temperature for 2 hours still meets the maximum allowable limit, but best practice is to refrigerate within 1 hour if the room temperature is high (above 90°F/32°C), which might not reflect consistent safe food handling in all conditions.

Correct Answer is A
Explanation
A. The client holds the cane on the stronger side of their body: Holding the cane on the stronger side improves balance and support while reducing strain on the weaker limb. It also helps coordinate movement and distribute weight more efficiently during ambulation.
B. The client advances the cane forward 12.7 cm (5 in): The cane should typically be advanced 15 to 25 cm (6 to 10 inches) forward for optimal support. Advancing it only 5 inches may provide insufficient balance assistance during walking.
C. The client moves their stronger leg forward first: The weaker leg should move forward after the cane to allow the stronger leg to support most of the weight. This pattern maximizes stability and safety during ambulation.
D. The top of the cane is at the same height as the client's waist: The cane should be level with the wrist crease when the client’s arms are relaxed at their sides, not at waist level. A cane that is too high or low can cause discomfort or improper posture.
Correct Answer is A
Explanation
A. Chlorine bleach: Chlorine bleach is the recommended disinfectant for cleaning surfaces contaminated with Clostridium difficile spores. It is effective in killing these hardy spores that are resistant to many other disinfectants.
B. Chlorhexidine: Chlorhexidine is an antiseptic commonly used for skin cleansing, not for disinfecting environmental surfaces contaminated with C. difficile. It is ineffective against spores.
C. Triclosan: Triclosan is an antimicrobial found in some personal care products, but it is not suitable or approved for disinfecting surfaces in healthcare settings, especially against C. difficile.
D. Isopropyl alcohol: Alcohol-based disinfectants are ineffective against C. difficile spores. They do not have sporicidal activity and are not recommended for cleaning in cases of C. difficile infection.
