Nursing Elites

1. A group of students is reviewing the components of the endocrine system. The students demonstrate understanding of the review when they identify what as the primary function of this system?

• A. Regulation of water balance
• B. Hormonal secretion
• C. Cellular metabolism
• D. Growth stimulation

Correct answer: B

Rationale: The primary function of the endocrine system is hormonal secretion. This system is responsible for producing and releasing hormones that regulate various bodily functions such as growth, metabolism, and mood. Choice A, regulation of water balance, is more related to the functions of the renal system rather than the endocrine system. Choice C, cellular metabolism, is a general cellular process that involves various systems, not specific to the endocrine system. Choice D, growth stimulation, though hormones can influence growth, it is not the primary function of the endocrine system. Therefore, the correct answer is B.

2. When developing the plan of care for a child with burns requiring fluid replacement therapy, what information would the nurse expect to include?

• A. Administration of colloid initially followed by a crystalloid
• B. Determination of fluid replacement based on the type of burn
• C. Administration of most of the volume during the first 8 hours
• D. Monitoring of hourly urine output to achieve less than 1 mL/kg/hr

Correct answer: C

Rationale: The correct answer is C. In fluid replacement therapy for burns, the majority of the volume should be administered within the first 8 hours to prevent shock and maintain perfusion. Choice A is incorrect because crystalloids are typically administered first in fluid resuscitation for burns. Choice B is incorrect as fluid replacement in burn patients is primarily determined by the extent of the burn injury rather than the type of burn. Choice D is incorrect as the goal for hourly urine output in burn patients is generally higher, aiming for 1-2 mL/kg/hr in children to ensure adequate renal perfusion and prevent dehydration.

3. A newborn is admitted to the neonatal intensive care unit (NICU) with choanal atresia. Which part of the infant’s body should the nurse assess?

• A. Rectum
• B. Nasopharynx
• C. Intestinal tract
• D. Laryngopharynx

Correct answer: B

Rationale: Choanal atresia is a congenital condition that presents with a blockage in the nasal passages at the junction of the nasal cavity and the nasopharynx. To assess and confirm the diagnosis of choanal atresia, the nurse should focus on assessing the nasopharynx. Choices A, C, and D are incorrect as choanal atresia specifically involves a blockage in the nasal passages, not the rectum, intestinal tract, or laryngopharynx. By assessing the nasopharynx, the severity of the obstruction can be determined, aiding in planning appropriate interventions for the newborn.

4. How should you care for an alert 4-year-old child with a mild airway obstruction, who has respiratory distress, a strong cough, and normal skin color?

• A. Back blows, abdominal thrusts, transport
• B. Oxygen, avoiding agitation, transport
• C. Assisting ventilations, back blows, transport
• D. Chest thrusts, finger sweeps, transport

Correct answer: B

Rationale: The correct approach for an alert 4-year-old child with a mild airway obstruction, respiratory distress, a strong cough, and normal skin color is to provide oxygen, avoid agitation, and arrange for transport. Oxygen helps support breathing, avoiding agitation prevents worsening of the obstruction, and transport ensures the child receives further medical evaluation and treatment. Choices A, C, and D involve techniques that are not recommended for a mild airway obstruction in this scenario. Back blows, abdominal thrusts, chest thrusts, and finger sweeps are interventions used for different situations and not suitable for a child with the described symptoms.

5. The nurse is assessing a 9-year-old girl with a history of tuberculosis at age 6 years. She has been losing weight and has no appetite. The nurse suspects Addison disease based on which assessment findings?

• A. Arrested height and increased weight
• B. Thin, fragile skin and multiple bruises
• C. Hyperpigmentation and hypotension
• D. Blurred vision and enuresis

Correct answer: C

Rationale: In a child with suspected Addison disease, the presence of hyperpigmentation (bronzing of the skin) and hypotension are key clinical findings. Hyperpigmentation is due to increased ACTH stimulation, resulting in melanocyte stimulation. Hypotension occurs due to decreased aldosterone production and subsequent sodium loss. Choices A, B, and D are incorrect. Arrested height and increased weight are not typical of Addison disease; thin, fragile skin and multiple bruises are more indicative of conditions like Cushing's syndrome; blurred vision and enuresis are not typically associated with Addison disease.
