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 2-year-old is admitted to the hospital with possible encephalitis, and a lumbar puncture is scheduled. Which information should the nurse provide this child concerning the procedure?

• A. Describe the side-lying, knees-to-chest position that must be assumed during the procedure.
• B. Explain that fluids cannot be taken for 8 hours before the procedure and for 4 hours after the procedure.
• C. Reassure the child that there will be no restrictions on activity after the procedure is completed.
• D. Tell the child to expect loud clicking noises during the procedure that may be slightly annoying.

Correct answer: A

Rationale: Children, especially young ones, benefit from knowing what position they will be in during a procedure as it helps them understand and feel more in control. Describing the side-lying, knees-to-chest position can reduce anxiety and promote cooperation during the lumbar puncture. Choice B is incorrect because the question is about preparing the child for the procedure, not about pre-procedure fasting requirements. Choice C is incorrect because there may be restrictions on activity after the procedure. Choice D is incorrect because mentioning loud clicking noises may increase the child's anxiety and fear.

3. When developing a behavior modification program for an extremely aggressive 10-year-old boy, what should the nurse do first?

• A. Determine what activities, foods, and toys the child enjoys
• B. Evaluate the child’s previous reactions to punishment
• C. Provide the child with positive feedback
• D. Encourage other children on the unit to describe the token system

Correct answer: A

Rationale: The first step in developing a behavior modification program for an aggressive child is to determine what activities, foods, and toys the child enjoys. Understanding the child's preferences allows the nurse to personalize the program, making it more engaging and effective. This approach increases the chances of success in modifying the aggressive behavior. Evaluating previous reactions to punishment (Choice B) may be important but comes later in the process. Providing positive feedback (Choice C) is beneficial but should come after tailoring the program. Encouraging other children to describe the token system (Choice D) is not the initial step; the focus should be on individualizing the program for the specific child first.

4. Which statement by a school-aged client going to summer camp indicates the best understanding of the mode of transmission of Lyme disease?

• A. I'll cover my mouth with a wet cloth if there's too much dust blowing.
• B. Cuts and scrapes need to be washed out and covered right away.
• C. I'm not going to swim where the water is standing still or feels too hot.
• D. I have to wear long sleeves and pants when we're hiking around the pond.

Correct answer: D

Rationale: The correct answer is D. Wearing long sleeves and pants helps prevent tick bites, which can transmit Lyme disease. Ticks carrying Lyme disease are often found in wooded or grassy areas, so covering exposed skin can reduce the risk of being bitten by an infected tick. Choices A, B, and C do not address the specific mode of transmission of Lyme disease through tick bites, making them incorrect.

5. A 7-year-old child is admitted to the hospital with nephrotic syndrome. The nurse notes that the child has gained 3 pounds in the past 24 hours. What should the nurse do first?

• A. Administer a diuretic as prescribed
• B. Restrict the child’s fluid intake
• C. Notify the healthcare provider
• D. Measure the child’s abdominal girth

Correct answer: C

Rationale: In a child with nephrotic syndrome experiencing sudden weight gain, the priority action for the nurse is to notify the healthcare provider. This weight gain could indicate worsening edema or fluid retention, necessitating immediate medical evaluation and intervention. The healthcare provider can conduct a comprehensive assessment, order necessary tests, and adjust the treatment plan accordingly. Administering a diuretic, restricting fluid intake, or measuring abdominal girth should not be initiated without healthcare provider consultation to ensure appropriate management of the child's condition.
