Exam Cram NCLEX RN Practice Questions Questions
Question 1 of 5
A child is diagnosed with Hirschsprung's disease. The nurse is teaching the parents about the cause of the disease. Which statement, if made by the parent, supports that teaching was successful?
Correct Answer: A
Rationale: Hirschsprung's disease, also known as congenital aganglionosis or megacolon, is characterized by the absence of ganglion cells in the rectum and, sometimes, extending into the colon. Choice A correctly explains the cause of Hirschsprung's disease. Choice B is incorrect as it describes celiac disease, which is related to gluten intolerance. Choice C is inaccurate as it describes symptoms of irritable bowel syndrome, not the cause of Hirschsprung's disease. Choice D is wrong as it pertains to lactose intolerance, not Hirschsprung's disease.
Question 2 of 5
The clinic nurse is obtaining data about a child with a diagnosis of lactose intolerance. Which data should the nurse expect to obtain on assessment?
Correct Answer: A
Rationale: Lactose intolerance commonly presents with frothy stools and diarrhea due to the inability to digest lactose. Other symptoms include abdominal distension, crampy abdominal pain, and excessive flatus. Foul-smelling ribbon stools are indicative of Hirschsprung's disease, not lactose intolerance. Profuse, watery diarrhea and vomiting are more characteristic of celiac disease. Diffuse abdominal pain unrelated to meals or activity is a typical symptom of irritable bowel syndrome, not lactose intolerance.
Question 3 of 5
The nurse has provided dietary instructions to the mother of a child with celiac disease. The nurse determines that further instruction is needed if the mother states that she will include which food item in the child's nutritional plan?
Correct Answer: C
Rationale: In celiac disease, individuals need to avoid gluten-containing foods like wheat, rye, barley, and oats. Oatmeal contains gluten unless it is specifically labeled as gluten-free. Corn and rice are safe alternatives for individuals with celiac disease as they do not contain gluten. Chicken is a naturally gluten-free protein source. While vitamin supplements may be necessary to address deficiencies due to malabsorption, oatmeal poses a risk of gluten exposure, making it an incorrect choice for a child with celiac disease.
Question 4 of 5
A child is suspected of suffering from intussusception. The nurse should be alert to which clinical manifestation of this condition?
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.
Question 5 of 5
While suctioning the endotracheal tube of an adult client, what level of pressure should the nurse apply?
Correct Answer: B
Rationale: When suctioning the endotracheal tube of an adult client, the nurse should set the suction apparatus at a level no higher than 150 mmHg, with a preferable level between 100 and 120 mmHg. Suction pressure that is too high can contribute to the client's hypoxia. Alternatively, too low suction pressure may not clear adequate amounts of secretions. Choice A (70-80 mmHg) is too low and may not effectively clear secretions. Choices C (150-170 mmHg) and D (200 mmHg) are too high and can potentially harm the client by causing hypoxia or damaging the airway.
