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. The nurse is caring for a 12-year-old boy with idiopathic thrombocytopenia. The nurse is providing discharge instructions about home care and safety recommendations to the boy and his parents. Which response indicates a need for further teaching?

• A. We should avoid aspirin and medications like ibuprofen.
• B. He can resume participation in football in 2 weeks.
• C. Swimming would be a great activity.
• D. Our son cannot take any antihistamines.

Correct answer: B

Rationale: Choice B indicates a need for further teaching because participation in contact sports like football should be avoided in children with idiopathic thrombocytopenia due to the increased risk of bleeding. Choices A, C, and D are correct. Avoiding aspirin and medications like ibuprofen helps prevent bleeding complications. Swimming is a safe physical activity that can be recommended. Antihistamines do not pose a significant risk in this case and can be used if needed.

3. Based on developmental norms for a 5-year-old child, a healthcare professional decides to withhold a scheduled dose of digoxin (Lanoxin) elixir and notify the healthcare provider. Below what apical pulse did the healthcare professional withhold the medication?

• A. 60 beats/min
• B. 70 beats/min
• C. 90 beats/min
• D. 100 beats/min

Correct answer: C

Rationale: For a 5-year-old child, an apical pulse below 90 beats/min is an indicator to withhold digoxin. Digoxin is a medication that affects the heart, and in pediatric patients, monitoring the pulse rate is crucial due to the risk of bradycardia (slow heart rate) as a potential side effect. In this case, an apical pulse of 90 beats/min or lower indicates a heart rate that may be too slow for a child of this age, warranting the withholding of digoxin and prompt notification of the healthcare provider. Choices A, B, and D are not within the critical range specified for withholding digoxin in a 5-year-old child and would not necessitate withholding the medication.

4. An infant is admitted to the neonatal intensive care unit (NICU) with exstrophy of the bladder. What covering should the nurse use to protect the exposed area?

• A. Loose diaper
• B. Dry gauze dressing
• C. Moist sterile dressing
• D. Petroleum jelly gauze pad

Correct answer: C

Rationale: In cases of exstrophy of the bladder, a moist sterile dressing is the most appropriate choice to protect the exposed bladder tissue. Moist sterile dressings help maintain a clean environment, prevent infection, and promote healing. A loose diaper (Choice A) may not provide adequate protection and may lead to contamination. Dry gauze dressing (Choice B) could adhere to the wound and cause trauma upon removal. Petroleum jelly gauze pad (Choice D) is not ideal as it may not provide the necessary barrier against infection and could potentially cause irritation.

5. What is the priority nursing intervention for a child with a diagnosis of acute lymphoblastic leukemia (ALL) receiving chemotherapy?

• A. Preventing infection
• B. Administering chemotherapy
• C. Providing nutritional support
• D. Monitoring fluid intake

Correct answer: A

Rationale: The priority nursing intervention for a child with acute lymphoblastic leukemia (ALL) receiving chemotherapy is to prevent infection. Chemotherapy compromises the child's immune system, increasing susceptibility to infections. Preventing infection is crucial to avoid potential complications such as sepsis, which can be life-threatening. Administering chemotherapy is essential for treating ALL but preventing infection takes precedence due to the increased risk of infections associated with chemotherapy-induced immunosuppression. Providing nutritional support is important for overall health but preventing infections is more critical in this context. Monitoring fluid intake is significant, but the priority is to prevent infections that can have severe consequences in an immunocompromised child.
