One of the following is false about CNS leukemia:

Correct Answer: D

Rationale: In pediatric nursing, understanding CNS leukemia is crucial for providing effective care to pediatric oncology patients. The correct answer, Option D, "None of the above," is the correct choice because CNS leukemia does not necessarily always have a bad prognosis, increased intracranial tension, or guaranteed relapse. Firstly, CNS leukemia prognosis can vary depending on various factors such as the subtype of leukemia, the response to treatment, and the overall health of the patient. While CNS involvement in leukemia can complicate treatment, it does not always indicate a uniformly bad prognosis. Secondly, while increased intracranial tension can occur in some cases of CNS leukemia due to tumor growth or accumulation of leukemic cells in the brain and spinal cord, it is not a universal feature of all cases. Lastly, while relapse is a concern in leukemia treatment, not all cases experience relapse, and the likelihood of relapse can be influenced by the type of leukemia, the response to treatment, and other individual factors. In an educational context, it is important for pediatric nurses to have a comprehensive understanding of CNS leukemia to provide optimal care to pediatric patients with this condition. By knowing the nuances and variations in presentation and prognosis, nurses can collaborate effectively with the healthcare team to develop individualized care plans and support patients and their families through the treatment journey.

Correct Answer: C

Rationale: Rationale: The correct answer is C) 8 months. At around 8 months of age, most infants develop the physical strength and coordination required to sit steadily unsupported. This milestone is part of their gross motor skill development. Infants typically start by propping themselves up on their hands around 4 months, then progress to sitting with support, and finally, by 8 months, they can sit steadily without assistance. Option A) 4 months is incorrect because infants at this age are usually able to hold their heads up and may be able to prop themselves up on their arms briefly, but they are not yet able to sit steadily unsupported. Option B) 6 months is incorrect as well, as while some infants may start to sit with support around this age, sitting steadily without assistance is more commonly achieved closer to 8 months. Option D) 10 months is incorrect because by 10 months, most infants have already mastered sitting steadily unsupported and have moved on to other developmental milestones. Understanding the typical age range for developmental milestones in infants is crucial for pediatric nurses as it helps in monitoring the growth and development of children under their care. It also aids in early identification of any potential delays or issues that may require further evaluation or intervention.

Correct Answer: B

Rationale: In pediatric nursing, understanding developmental milestones is crucial for assessing a child's growth and well-being. The correct answer to the question, "At what age should the nurse expect an infant to begin smiling in response to pleasurable stimuli?" is B) 2 months. At around 6-8 weeks of age, infants typically start to exhibit social smiles in response to stimuli like a caregiver's face or voice, indicating their ability to engage socially and form emotional bonds. This milestone is an essential indicator of a child's healthy social and emotional development. Option A) 1 month is incorrect because while infants may display reflex smiles in their sleep shortly after birth, genuine social smiles typically emerge a bit later, around 6-8 weeks. Option C) 3 months is incorrect as infants usually begin smiling socially before this age, demonstrating early social interaction skills and attachment to caregivers. Option D) 4 months is incorrect because by this age, infants should already be engaging in social smiling and have progressed to more advanced social behaviors. Understanding these developmental timelines is vital for nurses to monitor infants' progress accurately, identify potential developmental delays early, and provide appropriate interventions or referrals when needed to support optimal growth and development.

Correct Answer: D

Rationale: The correct answer is D) Most children are highly susceptible from birth. In pediatric nursing, understanding the susceptibility to pertussis is crucial for providing appropriate care and preventive measures. Pertussis, also known as whooping cough, is a highly contagious respiratory disease that can be severe, especially in young children. This disease is caused by the bacterium Bordetella pertussis. Option A is incorrect because neonates are not immune to pertussis in the first few months of life. In fact, infants are at high risk of severe complications from pertussis due to their immature immune systems. Option B is incorrect because although passive immunity can be passed from mother to infant through maternal antibodies, this protection is not guaranteed and is not a reliable method of prevention against pertussis. Option C is incorrect because children younger than 1 year are actually at higher risk of contracting pertussis due to their vulnerability to infections and the fact that they are not fully vaccinated yet. The correct answer, D, highlights the vulnerability of most children to pertussis from birth due to their lack of immunity and susceptibility to infections. It emphasizes the importance of vaccination and preventive measures to protect children from this potentially serious disease. Pediatric nurses play a key role in educating parents about the need for timely vaccination and recognizing the signs and symptoms of pertussis to ensure early intervention and treatment.

Correct Answer: D

Rationale: The correct answer is D) 13-18. The assessment of seriousness of adolescent drug abuse score categorizes scores into ranges to determine the severity of drug abuse in adolescents. A score falling between 13-18 is considered serious, indicating a higher level of drug abuse that requires immediate intervention and support. Option A) 0-3 is incorrect because this score range is considered minimal or low severity, suggesting less urgent intervention may be needed. Option B) 8-Mar is incorrect as well, as this range falls within the moderate severity category, indicating a higher level of concern than minimal but not as serious as the score range for severe cases. Option C) 13-Aug is also incorrect because it is not a standard score range used in the assessment tool. It is important to understand the specific score ranges in the assessment tool to accurately gauge the severity of drug abuse in adolescents. In an educational context, understanding the severity levels of adolescent drug abuse is crucial for healthcare providers working with this population. Recognizing the seriousness of the issue based on assessment scores helps in providing appropriate interventions and support to address the needs of adolescents struggling with drug abuse. It highlights the importance of early identification and intervention to prevent further harm and promote recovery in these vulnerable individuals.
