Nursing Elites

1. The clinic nurse reviews the record of an infant and notes that the primary healthcare provider has documented a diagnosis of suspected Hirschsprung's disease. The nurse reviews the assessment findings documented in the record, knowing that which sign most likely led the mother to seek healthcare for the infant?

• A. Diarrhea
• B. Projectile vomiting
• C. Regurgitation of feedings
• D. Foul-smelling, ribbon-like stools

Correct answer: D

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or aganglionic megacolon, is a congenital anomaly characterized by an absence of ganglion cells in the rectum and other areas of the affected intestine. A key clinical manifestation of Hirschsprung's disease is chronic constipation that starts in the first month of life, leading to pellet-like or ribbon-like stools that have a foul smell. Another sign is the delayed passage or absence of meconium stool in the neonatal period. In addition to foul-smelling, ribbon-like stools, bowel obstruction (especially in the neonatal period), abdominal pain and distention, and failure to thrive are also common clinical manifestations of this disorder. Options A, B, and C are not typically associated with Hirschsprung's disease, making them incorrect choices in this scenario.

2. A child is suspected of suffering from intussusception. The nurse should be alert to which clinical manifestation of this condition?

• A. Tender, distended abdomen
• B. Presence of fecal incontinence
• C. Incomplete development of the anus
• D. Infrequent and difficult passage of dry stools

Correct answer: A

Rationale: Intussusception is an invagination of a section of the intestine into the distal bowel, and it is the most common cause of bowel obstruction in children aged 3 months to 6 years. A tender, distended abdomen is a typical clinical manifestation of intussusception. The presence of fecal incontinence is not a characteristic presentation of intussusception; it describes encopresis, which generally affects preschool and school-aged children but is not specific to intussusception. Incomplete development of the anus describes imperforate anus, a disorder diagnosed in the neonatal period, not intussusception. The infrequent and difficult passage of dry stools is characteristic of constipation, a common issue in children that can occur at any age, although it often peaks at 2 to 3 years old.

3. The nurse is caring for a 10-year-old upon admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is

• A. Urinary output of 30 ml per hour
• B. No complaints of thirst
• C. Increased hematocrit
• D. Good skin turgor around burn

Correct answer: A

Rationale: The correct answer is urinary output of 30 ml per hour. In a 10-year-old child, this level of urinary output is indicative of adequate fluid replacement without suggesting overload. Monitoring urinary output is crucial in assessing fluid balance. Choices B, C, and D are incorrect. No complaints of thirst do not provide a direct assessment of fluid status. Increased hematocrit is a sign of dehydration, not adequate fluid replacement. Good skin turgor around the burn is a general assessment but may not directly reflect the child's overall fluid status.

4. The patient in the emergency room has a history of alprazolam (Xanax) abuse and abruptly stopped taking Xanax about 24 hours ago. He presents with visible tremors, pacing, fear, impaired concentration, and memory. Which intervention takes priority?

• A. Have the patient lie down on a stretcher with bed rails raised
• B. Offer the patient a cup of water and a small amount of food
• C. Reassure the patient about his well-being
• D. Inform the physician about the patient's Xanax withdrawal

Correct answer: A

Rationale: The 1-4 day period after Xanax withdrawal is critical as it poses the highest risk of life-threatening seizures. Alprazolam is a benzodiazepine, and sudden cessation can lead to severe withdrawal symptoms. The patient's visible tremors, fear, pacing, and cognitive impairment indicate a state of heightened distress and potential seizure risk. Placing the patient on a stretcher with raised bed rails is essential for seizure precautions, ensuring safety and preventing injury during a potential seizure. Offering water and food, reassuring the patient, or informing the physician about Xanax withdrawal are not immediate priorities compared to managing the risk of seizures in this high-risk situation.

5. A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?

• A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
• B. The ventilator coordinates delivered breaths with the client's respiratory efforts
• C. The ventilator provides a supplemental breath for every third breath of the client
• D. The ventilator provides breaths during the expiratory phase of the client's respirations

Correct answer: B

Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.
