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.

The mother of a 5-year-old boy with a myelomeningocele who has developed a sensitivity to latex is being taught by the nurse. Which response from his mother indicates a need for further teaching?
- A. He needs to wear a medical alert identification.
- B. I will need to inform his caregivers about this.
- C. A product's label always indicates if it is latex-free.
- D. He should avoid all contact with latex.
Correct Answer: C
Rationale: Choice C indicates a need for further teaching because not all products are clearly labeled as latex-free. It is essential for the mother to understand that she should not solely rely on product labels to determine latex content. She should be encouraged to verify with manufacturers and consult healthcare providers for accurate information. Choices A, B, and D are correct responses. Wearing a medical alert identification, informing caregivers, and ensuring the boy avoids all contact with latex are crucial steps in managing his sensitivity to latex and preventing potential allergic reactions.
A healthcare professional is preparing a presentation for a parent group about musculoskeletal injuries. When describing a child's risk for this type of injury, the professional integrates knowledge that bone growth occurs primarily in which area?
- A. Growth plate.
- B. Epiphysis.
- C. Physis.
- D. Metaphysis.
Correct Answer: B
Rationale: Bone growth primarily occurs in the epiphysis, which is the area where growth plates are located. The epiphysis is responsible for longitudinal bone growth. The growth plate, also known as the physis, is the cartilaginous region in the metaphysis where bone growth occurs. The metaphysis is the area between the epiphysis and diaphysis where bone lengthening occurs, but it is not the primary site of bone growth. Therefore, choices A, C, and D are incorrect.
A child with a diagnosis of congenital heart disease is admitted to the hospital. What should the nurse include in the child's care plan?
- A. Monitoring fluid status
- B. Encouraging activity
- C. Promoting a high-calorie diet
- D. Maintaining oxygen therapy
Correct Answer: A
Rationale: Monitoring fluid status is crucial for a child with congenital heart disease because these children are at risk of fluid overload which can worsen their condition. Monitoring fluid intake and output helps prevent complications like congestive heart failure. Encouraging activity (Choice B) should be individualized based on the child's condition and tolerance, as excessive activity can strain the heart. Promoting a high-calorie diet (Choice C) is not typically recommended for children with congenital heart disease unless specifically indicated, as excessive weight gain can worsen their cardiac function. Maintaining oxygen therapy (Choice D) may be necessary in some cases, but monitoring fluid status is a more fundamental aspect of care for children with congenital heart disease.
A child with a diagnosis of nephrotic syndrome is being treated with corticosteroids. What is an important nursing consideration?
- A. Monitor for signs of infection
- B. Monitor blood pressure
- C. Monitor for hyperglycemia
- D. Monitor for hypertension
Correct Answer: A
Rationale: When a child with nephrotic syndrome is undergoing treatment with corticosteroids, it is crucial to monitor for signs of infection. Corticosteroids can suppress the immune system, increasing the child's susceptibility to infections. Monitoring for signs of infection allows for early detection and prompt intervention, reducing the risk of complications. While monitoring blood pressure (choice B) is important in nephrotic syndrome, it is not the most immediate concern when the child is on corticosteroids. Monitoring for hyperglycemia (choice C) is relevant in corticosteroid therapy, but the priority in this scenario is to watch for signs of infection. Monitoring for hypertension (choice D) is important in nephrotic syndrome but is not the most critical consideration when the child is on corticosteroids.
During an oral cavity assessment of a 6-month-old infant, the parent inquires about which teeth will erupt first. How should the healthcare provider respond?
- A. Incisors
- B. Canines
- C. Upper molars
- D. Lower molars
Correct Answer: A
Rationale: Incisors are the teeth that typically erupt first in infants, usually around 6 months of age. These teeth play a crucial role in biting and cutting food. Canines, upper molars, and lower molars are not the primary teeth to erupt in infants. Canines usually erupt after incisors, while molars, whether upper or lower, come in later during the teething process.
