1. The nurse is assessing a newborn the day after birth. A high-pitched cry, irritability, and lack of interest in feeding are noted. The mother signed her own discharge against medical advice. What intervention is appropriate nursing care?
- A. Reduce the environmental stimuli
- B. Offer formula every 2 hours
- C. Talk to the newborn while feeding
- D. Rock the baby frequently
Correct answer: A
Rationale: The correct intervention is to reduce the environmental stimuli. In this scenario, the newborn is displaying signs of overstimulation and distress, which can be exacerbated by environmental factors. Offering formula every 2 hours (Choice B) may not address the underlying issue of overstimulation. Talking to the newborn while feeding (Choice C) and rocking the baby frequently (Choice D) may further stimulate the newborn, which is not appropriate in this case.
2. The nurse is developing a plan of care for a 7-year-old boy with diabetes insipidus. What is the priority nursing diagnosis?
- A. Deficient fluid volume related to dehydration
- B. Excess fluid volume related to edema
- C. Deficient knowledge related to fluid intake regimen
- D. Imbalanced nutrition related to excess weight
Correct answer: A
Rationale: The priority nursing diagnosis for a 7-year-old boy with diabetes insipidus is deficient fluid volume related to dehydration. Diabetes insipidus causes excessive thirst and urination, leading to fluid imbalance and potential dehydration. Choice B, excess fluid volume related to edema, is not a priority as diabetes insipidus is characterized by fluid loss, not retention. Choice C, deficient knowledge related to fluid intake regimen, may be important but is not the priority when the child is at risk of dehydration. Choice D, imbalanced nutrition related to excess weight, is not directly associated with the primary concern of fluid volume imbalance in diabetes insipidus.
3. A healthcare professional is planning care for a full-term newborn who is receiving phototherapy. Which of the following actions should the healthcare professional include in the plan of care?
- A. Dress the newborn in lightweight clothing.
- B. Avoid using lotion or ointment on the newborn's skin.
- C. Keep the newborn supine throughout treatment.
- D. Measure the newborn's temperature every 8 hours.
Correct answer: B
Rationale: When a newborn is receiving phototherapy, it is important to avoid using lotions or ointments on their skin as these products can lead to skin irritation and burns under the phototherapy lights. Dressing the newborn in lightweight clothing helps ensure proper exposure to the phototherapy lights. Keeping the newborn supine during treatment helps maximize exposure to the light. However, the key consideration in this scenario is to prevent skin irritation and burns by avoiding lotions or ointments.
4. Which neurotransmitter is most closely associated with mood regulation and is targeted by antidepressants?
- A. Serotonin
- B. Dopamine
- C. GABA
- D. Acetylcholine
Correct answer: A
Rationale: The correct answer is A: Serotonin. Serotonin plays a vital role in mood regulation, and its imbalance is often associated with depression. Many antidepressants function by boosting serotonin levels in the brain. Dopamine (Choice B) is more linked to reward and pleasure pathways in the brain, not primarily targeted for mood regulation. GABA (Choice C) is an inhibitory neurotransmitter that helps reduce neuronal excitability, not primarily associated with mood regulation. Acetylcholine (Choice D) is involved in muscle movement and cognitive functions, not the primary target of antidepressants for mood regulation.
5. You are called to a residence for a "sick" 5-year-old child. When you arrive and begin your assessment, you note that the child is unconscious with a respiratory rate of 8 breaths/min and a heart rate of 50 beats/min. Management of this child should consist of
- A. 100% oxygen via a non-rebreathing mask and rapid transport
- B. positive pressure ventilations with a BVM device and rapid transport
- C. chest compressions, artificial ventilations, and rapid transport
- D. back blows and chest thrusts while attempting artificial ventilations
Correct answer: C
Rationale: In a pediatric patient with an unconscious state, a respiratory rate of 8 breaths/min, and a heart rate of 50 beats/min, the appropriate management involves chest compressions, artificial ventilations, and rapid transport. These signs indicate severe respiratory and circulatory compromise, requiring immediate intervention to support breathing and circulation. Choice A (100% oxygen via a non-rebreathing mask) is not sufficient in this critical situation as the child requires more than just oxygen supplementation. Choice B (positive pressure ventilations with a BVM device) may be needed, but chest compressions are crucial in this scenario due to the presence of bradycardia. Choice D (back blows and chest thrusts) are not indicated for an unconscious child with respiratory and circulatory compromise; instead, immediate chest compressions are necessary to provide circulatory support.
