Nursing Elites

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. The practical nurse is providing care for a toddler who has just returned from surgery for a tonsillectomy. Which intervention is a priority in the immediate postoperative period?

• A. Offer clear fluids frequently.
• B. Encourage the child to cough and deep breathe.
• C. Monitor for frequent swallowing.
• D. Apply a warm compress to the throat area.

Correct answer: C

Rationale: Monitoring for frequent swallowing is a priority intervention in the immediate postoperative period after a tonsillectomy. Frequent swallowing may indicate bleeding from the surgical site, which requires immediate attention to prevent complications such as hemorrhage. Offering clear fluids frequently may not be appropriate immediately after surgery. Encouraging coughing and deep breathing may increase the risk of bleeding. Applying a warm compress to the throat area is not recommended as it can increase blood flow to the surgical site, potentially causing bleeding.

3. A child with cystic fibrosis is admitted to the hospital with respiratory distress. Which intervention should the practical nurse (PN) implement?

• A. Administer bronchodilators as prescribed.
• B. Limit fluid intake.
• C. Provide a high-fat diet.
• D. Encourage bed rest only.

Correct answer: A

Rationale: Administering bronchodilators as prescribed is crucial for managing respiratory distress in children with cystic fibrosis. Bronchodilators help to open the airways, facilitating easier breathing for the child. Limiting fluid intake, providing a high-fat diet, or encouraging bed rest only are not appropriate interventions for respiratory distress associated with cystic fibrosis. Limiting fluid intake could worsen dehydration, a high-fat diet is not recommended due to pancreatic insufficiency in cystic fibrosis, and bed rest alone does not address the respiratory distress.

4. A 16-year-old female student with a history of asthma controlled with both an oral antihistamine and an albuterol (ProAir) metered-dose inhaler (MDI) comes to the school nurse. The student complains that she cannot sleep at night, feels shaky, and her heart feels like it is 'beating a mile a minute.' Which information is most important for the nurse to obtain?

• A. When she last took the antihistamine.
• B. When her last asthma attack occurred.
• C. Duration of most asthma attacks.
• D. How often the MDI is used daily.

Correct answer: D

Rationale: The most crucial information for the nurse to obtain in this scenario is how often the metered-dose inhaler (MDI) is used daily. This information will help assess if the symptoms of insomnia, shakiness, and palpitations are potentially related to overuse of the inhaler, which can cause side effects such as tremors and palpitations. Monitoring the frequency of MDI usage is essential in managing asthma and ensuring appropriate medication administration.

5. The healthcare provider is preparing to suture a 10-year-old child with a lacerated forehead. Both parents and a 12-year-old sibling are present at the child's bedside. Which instruction best supports family involvement?

• A. While waiting for the healthcare provider, only one visitor may stay with the child.
• B. All of you should leave while the healthcare provider sutures the child's forehead.
• C. It is best if the sibling goes to the waiting room until the suturing is completed.
• D. Please decide who will stay when the healthcare provider begins suturing.

Correct answer: D

Rationale: Involving the family members in deciding who will stay when the healthcare provider begins suturing supports family involvement and helps reduce anxiety for the child. This approach respects the family's dynamics and preferences, promoting a supportive environment during the procedure.
