RN HESI Obstetrics and Pediatrics Exam 2 Questions
Question 1 of 5
One week after removing a tick that bit him, a student arrives at the school nurse's office with reports of flu-like symptoms. Which intervention should the school nurse implement first?
Correct Answer: B
Rationale: Observing for a rash around the tick bite site is the first intervention because a 'bull's-eye' rash is indicative of Lyme disease, a potential tick-borne illness. This guides further actions, prioritizing specific symptoms over general ones like fever, which is common to many illnesses.
Question 2 of 5
A one-month old male infant is brought to the clinic by his mother who states that her son has been vomiting forcefully after each meal for the last three days. The infant is afebrile, dehydrated, and pyloric stenosis is suspected. Which other findings should the nurse identify that are consistent with pyloric stenosis?
Correct Answer: B
Rationale: An olive-shaped mass in the abdominal area is a hallmark sign of pyloric stenosis, caused by hypertrophy of the pyloric muscle leading to gastric outlet obstruction. Other options like rooting or bile-stained emesis are not specific to this condition.
Question 3 of 5
A healthy 2-day-old newborn received the first dose of hepatitis B prior to being discharge home with the parents. The nurse should instruct the parents to return to the clinic for the infant's next dose of hepatitis B in how many months?
Correct Answer: D
Rationale: The hepatitis B vaccine schedule for infants involves three doses, with the second dose administered 1 to 2 months after the first, ensuring timely immunity development. The 2-month interval is appropriate for the next dose.
Question 4 of 5
The nurse knows that a shunt procedure is the therapy of choice in almost all cases of hydrocephalus. Which is the most common reason for revision of a child's ventriculoperitoneal shunt?
Correct Answer: C
Rationale: Malfunction of the valves is the most common reason for ventriculoperitoneal shunt revision, as valves can become blocked or stuck, leading to inadequate or excessive cerebrospinal fluid drainage.
Question 5 of 5
An infant diagnosed with respiratory syncytial virus is being discharged. Which instruction should the nurse include in caregiver education?
Correct Answer: D
Rationale: Performing bulb syringe suction with nasal saline drops helps clear mucus from the infant's nasal passages, easing breathing and feeding, which is critical for RSV management. Prone sleeping increases SIDS risk, and albuterol is not typically indicated.
