1. When children who are reared by adoptive parents are nonetheless more similar to their natural parents in a trait, it can be concluded that:
- A. the genetic characteristics of the children change over time.
- B. heredity is solely responsible for how a child grows.
- C. the environment is solely responsible for the development of those characteristics.
- D. genetics play a role in the development of those characteristics.
Correct answer: D
Rationale: When children exhibit traits that are more similar to their biological parents than their adoptive parents, it indicates a strong genetic influence on those traits. This similarity suggests that genetics play a significant role in the development of the observed characteristics. Choice A is incorrect because genetic characteristics do not change over time in this context. Choice B is incorrect as it implies that heredity is the only factor, disregarding the impact of the environment. Choice C is also incorrect as it suggests that only the environment influences trait development, overlooking the genetic contribution.
2. A client who is nonambulatory notifies the nurse that his trash can is on fire. After the nurse confirms the fire, which of the following actions should the nurse take next?
- A. Activate the emergency fire alarm
- B. Extinguish the fire
- C. Evacuate the client
- D. Confine the fire
Correct answer: C
Rationale: The correct action for the nurse to take next, after confirming the fire, is to evacuate the client. In a fire situation, following the RACE mnemonic, the priority is to rescue or evacuate clients to ensure their safety. Activating the emergency fire alarm (Choice A) is important to alert others and the fire department, but evacuating the client takes precedence. Extinguishing the fire (Choice B) may put the nurse and client at risk and is best left to trained personnel. Confining the fire (Choice D) is not the nurse's responsibility; the focus should be on ensuring the client's safety by evacuating them.
3. A client with depression is started on a selective serotonin reuptake inhibitor (SSRI). The client asks, 'How long will it take for this medication to work?' What is the best response by the nurse?
- A. It may take 2 to 4 weeks before you start feeling better.
- B. You should start feeling better within a few days.
- C. The medication works immediately to improve your mood.
- D. It may take up to 8 weeks for the medication to take full effect.
Correct answer: D
Rationale: Explaining that it may take up to 8 weeks for the medication to take full effect provides the client with a realistic expectation. SSRI medications typically require time to build up in the body and exert their therapeutic effects. Choice A is incorrect as it underestimates the time frame required for the medication to work. Choice B is incorrect as SSRIs do not produce immediate effects. Choice C is incorrect as it falsely states that the medication works immediately, which is not true for SSRIs.
4. The nurse suspects child abuse when assessing a 3-year-old boy and noticing several small, round burns on his legs and trunk that might be the result of cigarette burns. Which parental behavior provides the greatest validation for such suspicions?
- A. The parents' explanation of how the burns occurred is different from the child's explanation of how they occurred.
- B. The parents seem to dismiss the severity of the child's burns, saying they are very small and have not posed any problem.
- C. The parents become very anxious when the nurse suggests that the child may need to be admitted for further evaluation.
- D. The parents tell the nurse that the child was burned in a house fire which is incompatible with the nurse's observation of the type of burn.
Correct answer: D
Rationale: (D) provides the most validation for suspecting child abuse. The parent's explanation (subjective data) that the child was burned in a house fire is incompatible with the objective data observed by the nurse (small, round burns on the legs and trunk). (A) relies on subjective data, and the child's explanation might not accurately reflect the situation due to various factors like age or fear. The apparent lack of concern from the parents (B) is inconclusive as the nurse's interpretation of their reaction could be subjective. While parental anxiety (C) could hint at potential child abuse, it's important to note that most parents would naturally be anxious about their child's hospitalization, making it a less definitive indicator compared to the inconsistency in the explanation provided by the parents in option (D).
5. What is the most common cause of seizures in children?
- A. An abrupt rise in body temperature
- B. An inflammatory process in the brain
- C. A temperature greater than 102°F
- D. A life-threatening infection
Correct answer: C
Rationale: Seizures in children most often result from a temperature greater than 102°F, known as febrile seizures. Febrile seizures are commonly triggered by a rapid increase in body temperature due to infections or other causes. Choice A is incorrect as febrile seizures are not necessarily caused by the abrupt rise in body temperature alone. Choice B is incorrect as inflammatory processes in the brain may lead to other types of seizures but are not the most common cause in children. Choice D is incorrect as not all seizures in children are due to life-threatening infections.
