Nursing Elites

1. The charge nurse in the pediatric unit is teaching nursing students about pyloric stenosis. A student asks what causes pyloric stenosis. How should the nurse respond?

• A. One portion of the intestines invaginates or telescopes into another
• B. Hypertrophy of the circular pylorus muscle
• C. Relaxed cardiac sphincter
• D. Absent ganglion cells in the colon

Correct answer: B

Rationale: Pyloric stenosis is caused by the hypertrophy (thickening) of the circular muscle of the pylorus, leading to obstruction. Choice A is incorrect as it describes intussusception, not pyloric stenosis. Choice C is incorrect as a relaxed cardiac sphincter is related to gastroesophageal reflux. Choice D is incorrect as it describes Hirschsprung's disease, not pyloric stenosis.

2. An infant has been diagnosed with failure to thrive (FTT) classified according to the pathophysiology of defective utilization. The nurse understands that the reason for the FTT is most likely related to what?

• A. Cystic fibrosis
• B. Hyperthyroidism
• C. Congenital infection
• D. Breastfeeding problems

Correct answer: C

Rationale: FTT classified as defective utilization is often related to conditions like congenital infections, which interfere with the body's ability to effectively use nutrients. Conditions like cystic fibrosis and hyperthyroidism can also contribute to FTT but are categorized differently

3. What test is used to screen for carbohydrate malabsorption?

• A. Stool pH
• B. Urine ketones
• C. C urea breath test
• D. ELISA stool assay

Correct answer: A

Rationale: Stool pH testing is used to screen for carbohydrate malabsorption. A low pH indicates the presence of unabsorbed carbohydrates, which are fermented by bacteria, leading to acidic stool.

4. The nurses caring for a child are concerned about the child’s frequent requests for pain medication. During a team conference, a new nurse suggests they consider administering a placebo instead of the usual pain medication to see how the child responds. The team educates the nurse on why this is not appropriate and bases the decision on what knowledge?

• A. This practice is unjustified and unethical.
• B. This practice is effective in determining whether a child’s pain is real.
• C. The absence of a response to a placebo means the child’s pain has an organic basis.
• D. A positive response to a placebo will not occur if the child’s pain has an organic basis.

Correct answer: A

Rationale: The correct answer is A. The use of placebos without the patient’s consent is unethical and goes against the principles of beneficence and autonomy. Choice B is incorrect because using placebos does not provide reliable information about the presence or severity of the pain; it only indicates the response to the placebo itself. Choice C is wrong as the absence of a response to a placebo does not definitively mean that the child’s pain has an organic basis; there could be various reasons for the lack of response. Choice D is also incorrect as individuals may have a positive response to a placebo even if their pain has a significant organic cause. Therefore, the most appropriate response is A, emphasizing the ethical concerns surrounding the use of placebos without informed consent.

5. What findings on physical assessment of a neonate would indicate the need for further evaluation?

• A. Nystagmus
• B. Epstein pearls
• C. Low-set ears
• D. Positive Babinski reflex

Correct answer: C

Rationale: Low-set ears in a neonate suggest major abnormalities and should prompt further evaluation. The correct alignment of the top of the pinnae of the ear with the outer canthus of the eye is crucial. Nystagmus, an involuntary eye movement, is common in newborns and often resolves on its own. Epstein pearls, small cysts on the hard palate, are insignificant and disappear over time. A positive Babinski reflex is normal in infants up to 1 year of age. Therefore, the presence of low-set ears is the most concerning finding that requires immediate attention.
