Pediatric Practice Exam HESI

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: A

Rationale: The correct answer is A: Syndrome of inappropriate antidiuretic hormone (SIADH). Vasopressin is a medication used to treat diabetes insipidus by increasing water reabsorption in the kidneys. However, an excessive dose of vasopressin can lead to water retention, causing SIADH, which is characterized by dilutional hyponatremia. Choices B, C, and D are incorrect. Thyroid storm is a severe form of hyperthyroidism characterized by increased metabolism and can lead to life-threatening complications. Cushing syndrome results from excess cortisol production and is characterized by weight gain, hypertension, and other features. Vitamin D toxicity occurs due to an overdose of vitamin D, leading to hypercalcemia and symptoms such as nausea, vomiting, and weakness.

Correct Answer: C

Rationale: Avoiding gluten is not typically necessary for managing gastroesophageal reflux disease (GERD) in children. The correct dietary instruction for a 2-year-old with GERD would be to avoid high-fat foods. High-fat foods can relax the lower esophageal sphincter, leading to increased reflux symptoms. While spicy foods and dairy products may also trigger reflux in some individuals, the primary focus should be on avoiding high-fat foods due to their direct impact on the lower esophageal sphincter, which exacerbates GERD symptoms.

Correct Answer: B

Rationale: The correct answer is B: "Put on gloves because standard precautions are required." Standard precautions are essential in healthcare settings to prevent the transmission of infections, and wearing gloves is a crucial part of these precautions during immunizations. Choice A is incorrect because speaking with the nurse manager about techniques does not address the immediate need for wearing gloves. Choice C is incorrect because gloves are indeed needed to prevent the spread of infections. Choice D is incorrect as evaluating the child's appearance is not a substitute for wearing gloves which are a basic infection control measure.

Correct Answer: D

Rationale: In congenital hypothyroidism, infants often experience lethargy and difficulty staying awake due to low thyroid hormone levels. Choice A is incorrect as hypothyroidism can lead to poor growth in infants. Choice B is incorrect because hypothyroidism can cause decreased activity levels and lethargy rather than being active and playful. Choice C is incorrect as hypothyroidism can result in dry skin and poor skin tone, not necessarily pink and healthy-looking skin.
