Correct Answer: A

Rationale: A cough is a common clinical manifestation of pneumonia. Pneumonia often presents with symptoms such as cough, fever, chest pain, and difficulty breathing. The inflammation and infection in the lungs lead to the characteristic cough observed in patients with pneumonia. Diarrhea, rash, and vomiting are not typically associated with pneumonia and are less likely to be observed in a child with this condition.

Correct Answer: A

Rationale: The nurse should suspect measles based on the symptoms described, including the presence of Koplik spots (small, red spots with blue-white centers in the mouth). Measles typically presents with fever, irritability, runny nose, and a rash that begins on the face and spreads downward. Chickenpox (choice B) presents with vesicular lesions in different stages of healing and usually starts on the trunk. Fifth disease (choice C) presents with a 'slapped cheek' rash on the face and can cause joint pain. Scarlet fever (choice D) is characterized by a sandpaper-like rash, fever, and strawberry tongue.

Correct Answer: B

Rationale: Given the diversity of families in today's society, some believe that family should be defined as whatever the child and family say it is.

Correct Answer: B

Rationale: Covering the sac with saline-soaked nonadhesive gauze is essential in the preoperative care of an infant with myelomeningocele. This practice helps prevent infection and maintains moisture around the sac before surgery, promoting optimal healing outcomes. Positioning the infant supine with a pillow under the buttocks may be uncomfortable and unnecessary. Wrapping the infant snugly in a blanket does not address the specific care needs of the myelomeningocele. Applying a diaper over the sac can increase the risk of infection and should be avoided in this case.

Correct Answer: B

Rationale: The most important factor in preparing a toddler for additional surgery is their previous hospitalization experience. This familiarity with the hospital setting and procedures can help reduce anxiety and fear in the child. Choice A, meeting the child's wishes, may not always align with what is medically necessary or safe for the child. Choice C, preventing the child from staying with strangers, is important for general comfort but may not directly address the child's preparation for surgery. Choice D, ensuring ongoing parental affection, is crucial for emotional support but may not have the same impact as the child's previous hospitalization experience in preparing them for the surgery.
