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. A mother brings her 8-month-old baby boy to the clinic because he has been vomiting and having diarrhea for the last 3 days. Which assessment is most important for the nurse to make?

• A. Assess the infant's abdomen for tenderness
• B. Determine if the infant has been exposed to a virus
• C. Measure the infant’s pulse
• D. Evaluate the infant’s cry

Correct answer: C

Rationale: The most crucial assessment in this scenario is to measure the infant's pulse. Pulse measurement is essential to evaluate the severity of dehydration, which can be a significant concern in a baby experiencing vomiting and diarrhea for several days. Assessing the abdomen for tenderness may provide information on potential causes of symptoms but is not as urgent as monitoring hydration status. Determining exposure to a virus is important for infection control but does not directly address the immediate issue of dehydration. Evaluating the infant's cry, although a form of communication, does not provide critical information regarding the baby's physiological status in this situation.

3. What action should the nurse implement after the infusion is complete for a 16-year-old with acute myelocytic leukemia receiving chemotherapy via an implanted medication port at the outpatient oncology clinic?

• A. Administer Zofran
• B. Obtain blood samples for RBCs, WBCs, and platelets
• C. Flush the mediport with saline and heparin solution
• D. Initiate an infusion of normal saline

Correct answer: C

Rationale: After completing the chemotherapy infusion via the implanted medication port, the nurse should flush the mediport with saline and heparin solution. This action helps prevent clot formation in the port, ensuring its patency for future use and reducing the risk of complications associated with catheter occlusion. Administering Zofran (Choice A) is used for managing chemotherapy-induced nausea and vomiting, not for post-infusion care. Obtaining blood samples for RBCs, WBCs, and platelets (Choice B) is important for monitoring the patient's blood count but is not the immediate post-infusion priority. Initiating an infusion of normal saline (Choice D) is not necessary after completing the chemotherapy infusion.

4. What is the best response for a two-year-old boy who begins to cry when the mother starts to leave?

• A. Let's wave bye-bye to mommy.
• B. Two-year-olds usually stop crying the minute the parent leaves.
• C. Now be a big boy. Mommy will be back soon.
• D. Let's wave bye-bye to mommy.

Correct answer: D

Rationale: The best response for a two-year-old boy who begins to cry when the mother starts to leave is to wave bye-bye to mommy. This action helps the child understand that the separation is temporary and gives him a sense of closure. Choice A is the correct answer. Choice B is incorrect as it generalizes the behavior of two-year-olds. Choice C may invalidate the child's feelings by telling him to 'be a big boy' instead of acknowledging his emotions and providing comfort.

5. A 16-year-old adolescent with cystic fibrosis is admitted to the hospital with a respiratory infection. The nurse is teaching the adolescent about the importance of airway clearance techniques. Which statement by the adolescent indicates a need for further teaching?

• A. I should do my airway clearance exercises every day.
• B. I don’t need to do my airway clearance exercises if I feel okay.
• C. Airway clearance helps prevent mucus buildup in my lungs.
• D. I should continue my airway clearance routine even when I’m not sick.

Correct answer: B

Rationale: The correct answer is B. Airway clearance exercises are essential for individuals with cystic fibrosis to prevent mucus buildup in their lungs. It is crucial to perform these exercises regularly, even when feeling well, to maintain lung health and prevent complications. Choice A is correct as doing airway clearance exercises daily is necessary. Choice C is also accurate as airway clearance does indeed help prevent mucus buildup. Choice D is correct as it is important to continue the airway clearance routine even when not sick to maintain lung health. Choice B is incorrect because stating that airway clearance exercises are unnecessary when feeling okay demonstrates a misunderstanding of the importance of consistent airway clearance in cystic fibrosis management.
