1. What is the major criterion for diagnosing cognitive impairment in a child?
- A. An IQ of 75 or less
- B. Subaverage functioning
- C. An IQ of 70 or less
- D. Onset before 18
Correct answer: C
Rationale: The correct criterion for diagnosing cognitive impairment in a child is having an IQ of 70 or less. This range is typically used to define cognitive impairment in children. Choice A ('An IQ of 75 or less') is incorrect as the threshold is generally set at 70 or below. Choice B ('Subaverage functioning') is vague and does not specifically address the IQ criterion. Choice D ('Onset before 18') is unrelated to the primary criterion of IQ level used in diagnosing cognitive impairment in children.
2. What should be included in the medical management of sickle cell crisis?
- A. Information for the parents including home care
- B. Provisions for adequate hydration and pain management
- C. Pain management and administration of iron supplements
- D. Adequate oxygenation and factor VIII
Correct answer: B
Rationale: The correct answer is B: Provisions for adequate hydration and pain management. In managing a sickle cell crisis, it is essential to provide adequate hydration to prevent further sickling of red blood cells and ensure proper pain management to alleviate the severe pain associated with the crisis. While information for parents and home care may be important aspects of overall care, they are not specific to the immediate medical management of a sickle cell crisis. Administration of iron supplements is not recommended during a sickle cell crisis as it can potentially worsen the condition by promoting the production of more sickled red blood cells. Adequate oxygenation is crucial in sickle cell disease, but factor VIII is not typically part of the management of a sickle cell crisis.
3. An unlicensed assistive personnel (UAP) reports to the nurse that a client with a postoperative wound infection has a temperature of 103.8°F, blood pressure 90/70, pulse 124 beats/min, and respirations of 28 breaths/min. When the nurse assesses the client's findings, they include a mottled skin appearance and confusion. Which action should the nurse take first?
- A. Obtain a wound specimen for culture.
- B. Initiate an infusion of intravenous (IV) fluids.
- C. Transfer the client to the ICU.
- D. Assess the client's core temperature.
Correct answer: B
Rationale: The correct action for the nurse to take first is to initiate an infusion of intravenous (IV) fluids. In this scenario, the client is showing signs of sepsis, indicated by a high temperature, low blood pressure, rapid heart rate, and increased respiratory rate. Mottled skin appearance and confusion are also signs of poor perfusion. Initiating IV fluids is crucial in treating sepsis to maintain blood pressure and perfusion. Obtaining a wound specimen for culture (Choice A) can be important but is not the priority at this moment. Transferring the client to the ICU (Choice C) can be considered after stabilizing the client. Assessing the client's core temperature (Choice D) is not the immediate priority compared to addressing the signs of sepsis and poor perfusion.
4. Which other congenital defects are common in children with Down syndrome?
- A. Hypospadias
- B. Pyloric stenosis
- C. Heart defects
- D. Hip dysplasia
Correct answer: C
Rationale: The correct answer is C: Heart defects. Many children with Down syndrome are born with congenital heart defects. These heart abnormalities are more prevalent in individuals with Down syndrome than in the general population. Choices A, B, and D are incorrect because while they may be congenital defects in children, they are not commonly associated with Down syndrome. Hypospadias is a urogenital condition, pyloric stenosis affects the stomach, and hip dysplasia involves the hip joint, but these are not typically seen as frequently as heart defects in children with Down syndrome.
5. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?
- A. They involve antigen-antibody complexes.
- B. They are mediated by T cells and do not involve antibodies.
- C. They result in immediate allergic reactions.
- D. They are the least severe form of hypersensitivity.
Correct answer: B
Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.
