HESI RN
HESI Pediatric Practice Exam
1. A child who is admitted to the hospital with anemia is anxious, fearful, and hyperventilating. The nurse anticipates the child developing which acid-base imbalance?
- A. Metabolic acidosis
- B. Respiratory acidosis
- C. Respiratory alkalosis
- D. Metabolic alkalosis
Correct answer: C
Rationale: In this scenario, the child is hyperventilating, which leads to excessive loss of carbon dioxide. This loss of carbon dioxide causes respiratory alkalosis due to a decrease in the partial pressure of carbon dioxide in the blood. Therefore, the correct answer is respiratory alkalosis. Choices A, B, and D are incorrect. Metabolic acidosis is characterized by a decrease in pH and bicarbonate levels due to conditions like kidney disease. Respiratory acidosis is caused by retention of carbon dioxide, leading to an increase in the partial pressure of carbon dioxide. Metabolic alkalosis results from a loss of acid or an increase in bicarbonate levels.
2. The nurse is caring for a client who had a myocardial infarction 6 hours ago. The primary goal of care at this time is to
- A. Limit the effects of tissue damage
- B. Relieve pain and anxiety
- C. Prevent arrhythmias
- D. Reduce anxiety
Correct answer: A
Rationale: The correct answer is A: 'Limit the effects of tissue damage.' After a myocardial infarction, the primary goal of care is to limit the damage to the heart muscle. This includes interventions to improve blood flow, oxygenation, and prevent further complications. Choice B ('Relieve pain and anxiety') is important but secondary to addressing tissue damage. Choice C ('Prevent arrhythmias') is also crucial but falls under the broader goal of limiting tissue damage. Choice D ('Reduce anxiety') is essential for holistic care but is not the primary goal immediately after a myocardial infarction.
3. For a client with peripheral vascular disease (PVD) of the lower extremities who is trying to manage their condition well, which routine should the nurse evaluate as appropriate?
- A. Resting with the legs elevated above the level of the heart.
- B. Walking slowly but steadily for 30 minutes twice a day.
- C. Minimizing activity.
- D. Wearing antiembolism stockings at all times when out of bed.
Correct answer: B
Rationale: The correct answer is B. Walking slowly but steadily for 30 minutes twice a day is appropriate for clients with PVD as it helps stimulate collateral circulation and improve blood flow. Choice A is incorrect because while elevating the legs can help with symptoms temporarily, it is not as effective as walking for improving circulation. Choice C, minimizing activity, is not recommended as it can lead to further deconditioning and worsen symptoms. Choice D, wearing antiembolism stockings, is not specifically indicated for PVD and may not address the underlying circulation issues.
4. A 13-year-old client with type 1 diabetes is admitted to the hospital with a blood glucose level of 450 mg/dL. The client is lethargic and has fruity-smelling breath. What is the nurse’s priority action?
- A. Administer insulin as prescribed
- B. Start an IV infusion of normal saline
- C. Check the client’s urine for ketones
- D. Monitor the client’s vital signs
Correct answer: B
Rationale: The correct priority action for the nurse is to start an IV infusion of normal saline. The client's presentation with lethargy, fruity-smelling breath, and high blood glucose level indicates diabetic ketoacidosis (DKA). IV fluids are essential to correct dehydration and help stabilize the client's condition. Checking for ketones in the urine is important, but fluid replacement takes precedence to address the immediate risk of dehydration and electrolyte imbalances. Administering insulin is also a crucial intervention for DKA, but fluid resuscitation should first be initiated.
5. An elderly client with a fractured left hip is on strict bedrest. Which nursing measure is essential to the client's nursing care?
- A. Do not massage any reddened areas.
- B. Encourage passive range of motion exercises on extremities.
- C. Position the client laterally, supine, and prone in sequence.
- D. Gently lift the client when moving into a desired position.
Correct answer: D
Rationale: The essential nursing measure for a client with a fractured left hip on strict bedrest is to gently lift the client when moving into a desired position (D). This helps to avoid shearing forces and prevents further injury. Massaging reddened areas (A) should be avoided to prevent skin damage. Active range of motion exercises (B) may be limited due to pain and muscle spasms in the affected leg. The position described in (C) is contraindicated for a client with a fractured left hip as it may cause additional harm.
