Correct Answer: B

Rationale: Avoiding sharing of towels and washcloths, using bleach when laundering, and taking daily baths with antibacterial soap are critical to prevent the spread of MRSA. Cold water is not effective for laundering in these cases.

Correct Answer: D

Rationale: The second dose of the hepatitis A vaccine is recommended 6 months after the first dose to ensure full immunity.

Correct Answer: D

Rationale: The correct answer is D because at 9 months, infants become more mobile, increasing the risk of choking hazards from small objects left on the floor. Cautioning about putting the infant in a walker (Choice A) is not as crucial at this age as warning about choking hazards. While advising how to create a toddler-safe home (Choice B) is essential, the most critical concern at 9 months is small objects. Instructing on safety procedures during baths (Choice C) is important but does not address the immediate risk of choking hazards associated with small objects.

Correct Answer: B

Rationale: Being persistent through 10 to 15 minutes of food refusal is recommended to help increase caloric intake in infants with FTT. Establishing a routine and using developmental stimulation can also be helpful, but the priority is ensuring adequate caloric intake.

Correct Answer: B

Rationale: Administering antibiotics on schedule is crucial in treating a UTI effectively and preventing complications. Antibiotics help to eliminate the infection-causing bacteria from the urinary tract. While maintaining adequate nutrition and hydration are important aspects of care, the priority in a UTI is to target the infection with antibiotics. Preventing enuresis (bedwetting) is not directly related to the treatment of the infection. Fluid restriction is not recommended in the management of a UTI; in fact, encouraging adequate fluid intake helps flush out bacteria from the urinary tract.
