HESI Pediatrics Practice Exam
1. The healthcare provider is evaluating the effects of thyroid therapy used to treat a 5-month-old with hypothyroidism. Which behavior indicates that the treatment has been effective?
- A. Laughs readily, turns from back to side.
- B. Has strong Moro and tonic neck reflexes.
- C. Keeps fists clenched, opens hands when grasping an object.
- D. Can lift head but not chest when lying on abdomen.
Correct answer: A
Rationale: In infants, laughing readily and turning from back to side are developmental milestones that indicate effective thyroid therapy and normal development. These actions demonstrate improved muscle tone, coordination, and overall growth, which are key indicators of successful treatment for hypothyroidism in infants. Choices B, C, and D describe behaviors that are not specific indicators of thyroid therapy effectiveness in treating hypothyroidism in infants.
2. A 15-year-old adolescent with anorexia nervosa is admitted to the hospital for severe weight loss. The nurse notes that the client has dry skin, brittle hair, and is severely underweight. What is the nurse’s priority intervention?
- A. Establish a therapeutic relationship with the client
- B. Monitor the client’s vital signs frequently
- C. Initiate a structured eating plan
- D. Provide education about healthy eating habits
Correct answer: C
Rationale: In this scenario, the priority intervention for the nurse is to initiate a structured eating plan. Anorexia nervosa is a serious eating disorder characterized by severe food restriction, which can lead to malnutrition and severe weight loss. By starting a structured eating plan, the nurse can ensure the client receives the necessary nutrition to begin the process of weight restoration and recovery. Monitoring vital signs is essential, but without addressing the nutrition deficiency, vital signs may not improve significantly. Establishing a therapeutic relationship is crucial for long-term care but may not address the immediate risk of malnutrition. Providing education about healthy eating habits is important but may not be effective initially due to the severity of the client's condition.
3. Following admission for cardiac catheterization, the nurse is providing discharge teaching to the parents of a 2-year-old toddler with tetralogy of Fallot. What instruction should the nurse give the parents if their child becomes pale, cool, and lethargic?
- A. Encourage oral electrolyte solution intake
- B. Assist the child to a recumbent position
- C. Contact their healthcare provider immediately
- D. Provide a quiet time by holding or rocking the toddler
Correct answer: C
Rationale: If a child with tetralogy of Fallot becomes pale, cool, and lethargic, these symptoms may indicate a hypoxic episode or worsening condition. It is crucial to contact the healthcare provider immediately for further evaluation and management to ensure the child's safety and well-being. Option A is incorrect because electrolyte solution intake is not the immediate action needed for these symptoms. Option B is incorrect as positioning alone may not address the underlying issue. Option D is incorrect as providing a quiet time is not appropriate if the child is experiencing concerning symptoms that require prompt medical attention.
4. The healthcare provider finds a 6-month-old infant unresponsive and calls for help. After opening the airway and finding the infant is still not breathing, which action should the provider take?
- A. Palpate femoral pulse and check for regularity.
- B. Deliver cycles of 30 chest compressions and 2 breaths.
- C. Give two breaths that make the chest rise.
- D. Feel the carotid pulse and check for adequate breathing.
Correct answer: C
Rationale: In pediatric basic life support, for an unresponsive infant who is not breathing normally, the correct action is to give two breaths that make the chest rise. This helps provide oxygen to the infant's body and is a crucial step in resuscitation efforts for infants in distress. Choices A, B, and D are incorrect. Palpating the femoral pulse or feeling the carotid pulse is not indicated in this scenario where the infant is unresponsive and not breathing. Delivering cycles of chest compressions and breaths is not the immediate action to take; the priority is to provide two breaths to help with oxygenation.
5. 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.
