HESI RN
HESI Pediatric Practice Exam
1. The infant scheduled for reduction of intussusception passes a soft-formed brown stool the day before the procedure. What intervention should the nurse implement?
- A. Instruct the parents that the infant needs to be NPO.
- B. Notify the healthcare provider of the passage of brown stool.
- C. Obtain a stool specimen for laboratory analysis.
- D. Ask the parents about recent changes in the infant's diet.
Correct answer: B
Rationale: Notifying the healthcare provider is crucial when an infant scheduled for intussusception reduction passes a soft-formed brown stool as it may indicate spontaneous reduction of the intussusception. The healthcare provider needs to be informed to assess if the procedure is still necessary or if further evaluation is required. Instructing the parents that the infant needs to be NPO (nothing by mouth) is not the immediate action required in this situation. Obtaining a stool specimen for laboratory analysis is not necessary as the soft-formed brown stool is likely a result of the intussusception spontaneously reducing. Asking about recent changes in the infant's diet is not the most appropriate action when brown stool is passed before the procedure for intussusception reduction.
2. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which assessment finding should be reported to the healthcare provider immediately?
- A. Blood pressure of 110/70 mmHg
- B. Heart rate of 80 beats per minute
- C. Fever of 100.4°F
- D. Respiratory rate of 24 breaths per minute
Correct answer: C
Rationale: The correct answer is C. A fever of 100.4°F is most concerning in a client with ESRD scheduled for hemodialysis as it may indicate an underlying infection, which can lead to serious complications in this population. Elevated body temperature can be a sign of sepsis, which requires immediate attention to prevent further deterioration. Reporting this finding promptly allows for timely intervention. Choices A, B, and D are within normal ranges and do not pose an immediate threat to the client's well-being in the context of preparing for hemodialysis.
3. The client with chronic renal failure who is on a low-sodium diet should avoid which of the following foods?
- A. Fresh fruits.
- B. Canned soups.
- C. Lean meats.
- D. Whole grain bread.
Correct answer: B
Rationale: Canned soups are high in sodium, which can lead to fluid retention and hypertension in clients with chronic renal failure who are on a low-sodium diet. Fresh fruits, lean meats, and whole grain bread are generally lower in sodium and can be included in a low-sodium diet. Lean meats provide essential protein, fresh fruits offer vitamins and minerals, and whole grain bread provides fiber, making them suitable choices for individuals with chronic renal failure.
4. A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?
- A. Administer IV calcium gluconate.
- B. Administer sodium polystyrene sulfonate (Kayexalate).
- C. Administer insulin with dextrose.
- D. Restrict potassium intake in the client's diet.
Correct answer: A
Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.
5. A healthcare professional prepares to administer sodium polystyrene sulfonate (Kayexalate) to a client. Before administering the medication, the professional reviews the action of the medication and understands that it:
- A. Releases bicarbonate in exchange for primarily sodium ions
- B. Releases sodium ions in exchange for primarily potassium ions
- C. Releases potassium ions in exchange for primarily sodium ions
- D. Releases sodium ions in exchange for primarily bicarbonate ions
Correct answer: B
Rationale: Sodium polystyrene sulfonate, such as Kayexalate, is a cation exchange resin that functions by releasing sodium ions in exchange for primarily potassium ions. This medication is commonly used to treat hyperkalemia, a condition characterized by elevated levels of potassium in the blood.
