Correct Answer: D

Rationale: At 10 months of age, pulling to a stand is a developmental milestone that most infants can achieve. Crawling typically occurs around 6-9 months, sitting without support around 6-8 months, and standing with assistance around 7-11 months. Therefore, choices A, B, and C are not the expected developmental milestones for a 10-month-old infant.

Correct Answer: B

Rationale: The correct answer is B: Covering the sac with saline-soaked nonadhesive gauze. This intervention is essential in caring for an infant with myelomeningocele as it helps prevent infection and maintains a moist environment around the sac before surgical repair. Positioning the infant supine with a pillow under the buttocks (Choice A) may be suitable for comfort but is not directly related to managing the myelomeningocele. Wrapping the infant snugly in a blanket (Choice C) and applying a diaper (Choice D) are not recommended as they can increase the risk of infection and damage to the sac.

Correct Answer: B

Rationale: The correct answer is B: Diarrhea. Rotavirus infection commonly presents with symptoms such as watery diarrhea, fever, vomiting, and abdominal pain. However, diarrhea is the hallmark symptom of rotavirus infection, often leading to dehydration in children. Abdominal pain (choice A) can also be present but is not as specific to rotavirus infection as diarrhea. Constipation (choice C) is not a typical symptom of rotavirus infection. While vomiting (choice D) can occur in rotavirus infection, it is more commonly associated with other gastrointestinal conditions.

Correct Answer: B

Rationale: In this scenario, the patient has requested not to be touched, indicating a need for sensitivity and understanding. Asking a female EMT-B to attempt to assess the patient is the most appropriate initial action as it respects the patient's need for privacy, comfort, and potentially reduces re-traumatization. Asking the patient to sign a release form (Choice A) is not suitable as it disregards the patient's immediate concerns. Explaining to the patient that she must be examined (Choice C) may further distress her and violate her autonomy. Transporting the patient without performing an assessment (Choice D) ignores the patient's expressed wishes and may lead to inadequate care.

Correct Answer: B

Rationale: The correct answer is B: Antifungals. Candidal diaper rash is caused by a yeast infection and is best treated with antifungal agents. Corticosteroids (choice A) may worsen fungal infections by suppressing the immune response. Antibiotics (choice C) are used to treat bacterial infections, not fungal infections like candidal diaper rash. Retinoids (choice D) are not typically used to treat candidal diaper rash in infants; they are more commonly used for dermatological conditions like acne.
