1. When caring for a child with Reye's Syndrome, which action should the nurse give the highest priority?
- A. Monitor intake and output
- B. Provide good skin care
- C. Assess level of consciousness
- D. Assist with range of motion
Correct answer: C
Rationale: Assessing the level of consciousness is crucial when caring for a child with Reye's Syndrome. Changes in neurological status can indicate deterioration of the condition, necessitating immediate medical attention. Monitoring intake and output is important but not the highest priority compared to assessing the child's level of consciousness. Providing good skin care and assisting with range of motion are also important aspects of care but take a lower priority than assessing the child's neurological status in this critical condition.
2. In what units are energy measurements expressed by most scientists and nutritionists outside the United States?
- A. newtons
- B. liters
- C. kilojoules
- D. kilocalories
Correct answer: C
Rationale: Kilojoules are the standard units of energy used by most scientists and nutritionists worldwide. Newtons are units of force, liters are units of volume, and kilocalories are more commonly used in the United States but not as widely adopted internationally for energy measurements. Therefore, the correct answer is 'kilojoules.'
3. The practical nurse administered 15 units of NPH insulin subcutaneously to a client before they consumed their breakfast at 7:30 AM. At what time is the client at an increased risk for a hypoglycemic reaction?
- A. 8:30 to 11:30 AM
- B. 3:30 to 7:30 PM
- C. 9:30 PM to midnight
- D. 1:00 to 5:00 AM
Correct answer: B
Rationale: NPH insulin, an intermediate-acting type, peaks approximately 8 to 12 hours after subcutaneous administration. Considering this, the client is most likely to experience a hypoglycemic reaction between 3:30 and 7:30 PM, making option B the correct answer. Choices A, C, and D are incorrect because they fall outside the peak time for a hypoglycemic reaction after administering NPH insulin.
4. During a home visit, the nurse assesses the skin of a client with eczema who reports that an exacerbation of symptoms has occurred during the last week. Which information is most useful in determining the possible cause of the symptoms?
- A. An old friend with eczema came for a visit.
- B. Recently received an influenza immunization.
- C. A grandson and his new dog recently visited.
- D. Corticosteroid cream was applied to eczema.
Correct answer: C
Rationale: The correct answer is C. Contact with the grandson's new dog could have introduced new allergens or irritants, exacerbating the eczema symptoms. Choice A is unrelated to the exacerbation of symptoms. Choice B, receiving an influenza immunization, is unlikely to directly cause an exacerbation of eczema symptoms. Choice D, applying corticosteroid cream, is a common treatment for eczema and would not likely be the cause of the exacerbation.
5. What explanation should the nurse give a parent about the purpose of a tetanus toxoid injection for their child?
- A. Passive immunity is conferred temporarily.
- B. Long-lasting active immunity is conferred.
- C. Lifelong active natural immunity is conferred.
- D. Passive natural immunity is conferred temporarily.
Correct answer: B
Rationale: The correct answer is B: Long-lasting active immunity is conferred. Tetanus toxoid injection works by stimulating the child's body to produce its antibodies, providing long-lasting active immunity. Choice A is incorrect because passive immunity is not conferred for life; it is temporary and involves receiving antibodies rather than producing them internally. Choice C is incorrect as the immunity conferred by the tetanus toxoid injection is not lifelong natural immunity but rather active immunity stimulated by the body's immune response. Choice D is also incorrect since passive natural immunity is not conferred by the tetanus toxoid injection, and it is not temporary.
