Pediatric Practice Exam HESI

Correct Answer: B

Rationale: The priority intervention for a 3-month-old infant hospitalized with respiratory syncytial virus (RSV) is to cluster care to conserve energy. Infants with RSV often have difficulty breathing and need to rest frequently. Clustering care involves grouping nursing interventions to allow for longer periods of rest between activities, which helps prevent exhaustion and conserve the infant's energy. Administering an antiviral agent is not the primary intervention for RSV, as it is a viral infection and antiviral agents are not typically used for RSV. Offering oral fluids is important for hydration but may not be the priority when the infant is struggling to breathe. Providing an antitussive agent should be done judiciously and under medical guidance, as suppressing the cough reflex can be detrimental in RSV cases where coughing helps clear airway secretions.

Correct Answer: C

Rationale: Preventing straining at stool is crucial postoperatively after heart surgery for tetralogy of Fallot to avoid increasing intrathoracic pressure and placing stress on the surgical site. This can help prevent complications and promote faster healing. While crying, coughing, and unnecessary movement are common postoperative behaviors, they are not specifically linked to worsening outcomes in this context. Straining at stool is particularly emphasized due to its potential to impact the surgical site and overall recovery process.

Correct Answer: B

Rationale: The correct answer is to use a soft toothbrush for oral care. Children with hemophilia have a decreased ability to form blood clots, leading to prolonged bleeding. Using a soft toothbrush helps prevent trauma to the gums and oral mucosa, reducing the risk of bleeding. Encouraging participation in contact sports (Choice A) is contraindicated in hemophiliac patients due to the high risk of injury and bleeding. Administering nonsteroidal anti-inflammatory drugs (Choice C) and aspirin (Choice D) should be avoided in hemophilia as they can further increase the risk of bleeding due to their antiplatelet effects.

Correct Answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis. This occurs due to impaired respirations, leading to the retention of carbon dioxide and the formation of carbonic acid. Choice A is incorrect as metabolic alkalosis is not expected in this situation. Choice B is incorrect as respiratory alkalosis does not align with the scenario of impaired respirations in severe asthma attacks. Choice D is also incorrect as it describes metabolic acidosis, which is not typically associated with severe asthma attacks.

Correct Answer: B

Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas are unlikely to lead to loss of necessary nutrients. Choice C is incorrect as it does not directly relate to the physiological risk of tap water enemas. Choice D is incorrect as shock from a sudden drop in temperature is not a common concern with tap water enemas.
