Pediatric Practice Exam HESI

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: C

Rationale: A caring relationship with family members is an external protective factor that promotes resilience in individuals, especially in adolescents. This support system provides a sense of security, stability, and emotional connection, which can help the teenager navigate challenges and setbacks. Choices A, B, and D allude to internal factors related to personal decision-making, self-awareness, and goal management, which are important but do not directly represent external protective factors involving external relationships or resources.

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 do not directly lead to loss of necessary nutrients. Choice C is incorrect as it focuses on emotional impact rather than physiological risks. Choice D is incorrect as shock from a sudden drop in temperature is not a common consequence of a tap water enema in this scenario.

Correct Answer: A

Rationale: The correct answer is A: 'High fever and Koplik spots.' Rubeola (measles) is characterized by a high fever and the presence of Koplik spots, which are not seen in rubella (German measles). Choice B, rash on the trunk with pruritus, is more indicative of rubella. Choice C, nausea, vomiting, and abdominal cramps, are not specific to either rubeola or rubella. Choice D, characteristics of a cold followed by a rash, is not a typical presentation of rubeola or rubella.

Correct Answer: C

Rationale: The most likely nursing diagnosis for a 1-month-old girl with trisomy 18, characterized by low-set ears and severe hypotonia, is 'Grieving related to the child's poor prognosis.' Trisomy 18 is associated with a poor prognosis, and families often experience grief as they come to terms with the challenges and uncertainties associated with the condition. 'Interrupted family process' may not be as relevant since the primary focus is on the child's condition. 'Deficient knowledge related to the genetic disorder' could be important but may not be the most likely initial concern, as emotional support for the family is crucial at this point. 'Ineffective coping related to the stress of providing care' is a broad diagnosis that does not specifically address the emotional response to the child's prognosis, which is the primary concern in this case.
