1. The healthcare provider is assessing an infant with pyloric stenosis. Which pathophysiological mechanism is the most likely consequence of this infant's clinical picture?
- A. Metabolic alkalosis.
- B. Respiratory acidosis.
- C. Metabolic acidosis.
- D. Respiratory alkalosis.
Correct answer: A
Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.
2. During a well baby visit, the parents explain that a soft bulge appears in the groin of their 4-month-old son when he cries or strains during stooling. The infant is scheduled for surgical repair of the inguinal hernia in two weeks. What should the parent be instructed to do if the hernia becomes incarcerated prior to the surgery?
- A. Use a rectal thermometer to strain during stooling.
- B. Gently manipulate the hernia for reduction.
- C. Offer oral electrolyte fluids for comfort.
- D. Give acetaminophen or aspirin for crying.
Correct answer: B
Rationale: In the case of an incarcerated inguinal hernia, gentle manipulation can sometimes help in reducing it before surgery. This action should be taken cautiously and immediately followed by seeking medical attention. It is important to note that attempting reduction should be done by a healthcare professional, and parents should be advised to seek urgent medical care if the hernia becomes incarcerated. Using a rectal thermometer to strain during stooling (Choice A) is not the correct approach for an incarcerated hernia and can worsen the condition. Offering oral electrolyte fluids for comfort (Choice C) or giving acetaminophen or aspirin for crying (Choice D) are not appropriate interventions for an incarcerated hernia and may delay necessary medical treatment.
3. A 10-year-old girl who has had type 1 diabetes mellitus (DM) for the past two years tells the nurse that she would like to use a pump instead of insulin injections to manage her diabetes. Which assessment of the girl is most important for the nurse to obtain?
- A. Understanding of the quality control process used to troubleshoot the pump
- B. Interpretation of fingerstick glucose levels that influence diet selections
- C. Knowledge of her glycosylated hemoglobin A1c levels for the past year
- D. Ability to perform the pump for basal insulin with mealtime boluses
Correct answer: A
Rationale: In a patient transitioning to an insulin pump, understanding the quality control process to troubleshoot the pump is crucial for ensuring proper and safe management of diabetes. This knowledge enables the individual to identify and address any issues that may arise with the pump, helping maintain optimal glycemic control and prevent complications. Choices B, C, and D, although important in diabetes management, are not as critical as ensuring the correct understanding of troubleshooting the pump, which directly impacts the girl's ability to effectively use the pump for insulin delivery.
4. A 6 year old who has asthma is demonstrating a prolonged expiratory phase and wheezing and has a 35% of personal best peak expiratory flow rate (PEFR). Based on these findings, what actions should the nurse take first?
- A. Administer a prescribed bronchodilator.
- B. Encourage the child to cough and deep breath.
- C. Report findings to the health care provider.
- D. Determine what triggers precipitated this attack.
Correct answer: A
Rationale: Administering a bronchodilator will help open the airways and improve breathing.
5. During a routine assessment of a 3-year-old at a community health center, the healthcare professional should be alert for signs of autism spectrum disorder. Which behavior by the child should prompt further evaluation for a possible autistic spectrum disorder?
- A. Engages in odd repetitive behaviors
- B. Shows indifference to verbal stimulation
- C. Strokes the hair of a hand-held doll
- D. Has a history of temper tantrums
Correct answer: A
Rationale: Engaging in odd repetitive behaviors is a hallmark sign of autism spectrum disorder in children. These behaviors can include repetitive movements, insistence on sameness, or specific routines. Recognizing and addressing these behaviors early can help in providing appropriate interventions and support for the child.
