Pediatric HESI Practice Questions

Correct Answer: B

Rationale: In a child with a disorder of the posterior pituitary gland, desmopressin acetate is commonly used to manage the condition by replacing the antidiuretic hormone. Instructing the parents to administer desmopressin acetate correctly is essential for the child's treatment. The other options are incorrect because growth hormone treatment, stopping treatment at puberty, and reporting signs of acute adrenal crisis are not directly related to managing a disorder of the posterior pituitary gland.

Correct Answer: B

Rationale: Allowing the child to play with a favorite toy while taking the medication is the best approach to gain cooperation. This strategy can help distract and calm the child during the medication administration process. Choice A may not be as effective with a young child who may not fully understand the explanation. Offering a reward (choice C) may reinforce negative behavior and create a dependency on rewards for cooperation. Giving the medication with food (choice D) may not always be appropriate and may not address the cooperation aspect.

Correct Answer: B

Rationale: The correct answer is B: Signs of dehydration. Infants with hypertrophic pyloric stenosis (HPS) are at high risk of dehydration due to frequent vomiting. Assessing for signs of dehydration, such as decreased urine output, dry mucous membranes, and sunken fontanelles, is crucial for early intervention and management. Choices A, C, and D are not the most critical assessments for HPS. The quality of the cry (choice A) may not provide as much relevant information in this case. Coughing up of feedings (choice C) may be a symptom but is not as crucial as assessing for dehydration. Characteristics of the stool (choice D) are important but assessing for signs of dehydration takes precedence due to the immediate risk it poses to the infant's health.

Correct Answer: C

Rationale: The correct answer is C, Chickenpox (varicella). Chickenpox is a viral disease characterized by a highly pruritic rash that typically starts on the abdomen and then spreads to other parts of the body, including the face and proximal extremities. It can lead to complications such as pneumonia and encephalitis. Rubella (German measles) presents with a mild rash and swollen lymph nodes; Rubeola (measles) also presents with a rash but starts on the face before spreading downwards; Scarlet fever is caused by Group A Streptococcus bacteria and is characterized by a rash, fever, and sore throat.

Correct Answer: B

Rationale: The priority nursing intervention for a 3-year-old child with Kawasaki disease is monitoring for coronary artery aneurysms. Kawasaki disease can lead to coronary artery complications, making early detection crucial in preventing serious outcomes. Administering IV immunoglobulin is a standard treatment for Kawasaki disease but does not take precedence over monitoring for potential complications. Encouraging fluid intake and providing nutritional support are important aspects of care but are not the priority when compared to monitoring for coronary artery aneurysms to prevent long-term cardiac issues.
