Pediatric Practice Exam HESI

Correct Answer: B

Rationale: The best approach in dealing with a child's tantrum is to not give in to their demands. By allowing the tantrum to continue until it ends, the child learns that this behavior is not effective in getting what they want. Offering a distraction (Choice A) might temporarily calm the child but does not address the underlying issue of the tantrum. Leaving the child with a babysitter (Choice C) does not teach the child how to handle such situations. Giving in to the child's demands (Choice D) reinforces the tantrum behavior.

Correct Answer: B

Rationale: The priority nursing intervention in a 4-year-old child admitted with bacterial pneumonia is administering antibiotics. Antibiotics are crucial for treating the infection and preventing potential complications. Administering antipyretics (Choice A) may help reduce fever, but addressing the underlying infection with antibiotics is the priority. Monitoring fluid intake (Choice C) is important for hydration but does not take precedence over administering antibiotics. Providing nutritional support (Choice D) is essential for overall care but is not the immediate priority when managing bacterial pneumonia.

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: 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: B

Rationale: The correct answer is B: 'Warmth at skin disruption site.' Cellulitis is characterized by localized warmth at the site of skin disruption, which indicates an infection. Choice A, 'Red, raised hair follicles,' is more typical of folliculitis. Choice C, 'Papules progressing to vesicles,' is suggestive of conditions like herpes simplex virus infections. Choice D, 'Honey-colored exudate,' is associated with impetigo, not cellulitis. When assessing cellulitis, nurses should primarily look for warmth, erythema, edema, and tenderness at the affected site.
