When a patient participates in a research study, the pediatric nurse's primary concern is to ensure that the:

Correct Answer: B

Rationale: In this scenario, option B is the correct answer because the primary concern of the pediatric nurse when a patient participates in a research study should be to ensure that the quality of care the patient receives will not be affected if they choose to withdraw from the study. This is crucial to uphold the ethical principle of beneficence, which requires healthcare providers to prioritize the well-being of their patients. Option A is incorrect because verbal consent from a parent or guardian alone is not sufficient to address the potential risks or changes in care that may arise from the research study. Option C is incorrect because while meeting the developmental needs of the patient is important, ensuring the continuity and quality of care takes precedence in this context. Option D is also incorrect because while research benefits are valuable, the immediate concern should be the patient's well-being and care provision. In an educational context, it is essential for pediatric nurses to understand the ethical considerations involved in research participation in pediatric care. By prioritizing the patient's well-being and ensuring that their care remains unaffected by research involvement, nurses uphold the principles of beneficence and patient-centered care, ultimately promoting ethical and responsible practice in pediatric healthcare.

Correct Answer: D

Rationale: In pediatric primary care, it is crucial to recognize developmental milestones and potential signs of developmental delays early on. The correct answer, D) 12 months, is when a child should typically start responding to their name. At this age, most children demonstrate social responsiveness and recognition of their name when called. Option A) 6 months is too early to expect consistent name response as infants are still developing their cognitive and social skills. Option B) 8 months is also premature for this skill to be fully established. Option C) 10 months might show some sporadic responses but not the consistent recognition expected at 12 months. Educationally, understanding these developmental markers aids healthcare providers in identifying potential concerns and initiating early interventions if needed. It also allows for appropriate counseling and support for parents in promoting their child's optimal development. By knowing when certain milestones should be reached, healthcare professionals can provide holistic and proactive care for children.

Correct Answer: D

Rationale: The most likely diagnosis in this case is D) Acrodynia. Acrodynia, also known as pink disease, is a rare condition caused by mercury exposure. The symptoms described in the question, such as peeling rash on hands and feet, irritability, photophobia, and tremor of the tongue, are classic manifestations of mercury toxicity in children. The history of the child's brothers playing with liquid mercury further supports this diagnosis. A) Measles is incorrect because the symptoms described do not align with those of measles, which typically presents with fever, cough, runny nose, and a characteristic rash starting on the face and spreading to the body. B) Fifth disease is unlikely as it presents with a "slapped cheek" rash on the face and a lacy rash on the trunk and limbs, not peeling rash on hands and feet. C) Kawasaki disease does not typically present with symptoms of mercury toxicity. It is characterized by fever, rash, conjunctivitis, swollen hands and feet, and inflammation of the blood vessels. Educationally, understanding the differential diagnosis of rashes and associated symptoms in pediatric patients is crucial for healthcare providers working in primary care settings. Recognizing the unique presentation of mercury toxicity in children, like in acrodynia, is essential for prompt diagnosis and appropriate management to prevent long-term complications. It highlights the importance of taking a detailed history, considering environmental exposures, and connecting clinical findings to potential causes.

Correct Answer: D

Rationale: In this question, the correct answer is D) speaks inhibition word 'no.' The developmental milestone of speaking the word "no" typically occurs around the age of 18 months to 2 years. At 10 months, children are usually beginning to babble, imitate sounds, say simple words like "mama" or "dada," follow simple commands with gestures, and point to objects or say their first words. Option A is incorrect because a 10-month-old child can typically say "mama" or "dada." Option B is incorrect because a 10-month-old child can usually follow a one-step command with gestures. Option C is incorrect because a 10-month-old child can often point to objects or say their first word. Educationally, understanding typical developmental milestones in children is crucial for healthcare providers working in pediatric primary care. Recognizing when a child should be reaching certain milestones can help identify potential developmental delays or concerns early on, allowing for timely interventions and support. It also enables healthcare providers to offer appropriate guidance to parents on what to expect in terms of their child's development.

Correct Answer: D

Rationale: The correct answer is D) 80%. The specificity of a test refers to its ability to correctly identify those without the condition (true negative rate). In this case, the indirect fluorescence antibody test for Campylobacter enteritis was positive in 30 out of 150 normal persons tested. Therefore, the test correctly identified 120 people as true negatives (150 - 30 = 120). To calculate specificity, we divide the number of true negatives by the total number of normal persons tested and multiply by 100. So, specificity = (120/150) x 100 = 80%. Option A) 20%, Option B) 40%, and Option C) 60% are incorrect because they do not accurately reflect the specificity of the test based on the information provided in the question. Educationally, understanding the concepts of sensitivity and specificity in diagnostic testing is crucial for healthcare professionals, especially in fields like pediatric primary care where accurate and rapid diagnosis is essential for effective treatment and management of conditions. Being able to interpret and calculate these values ensures that healthcare providers can make informed decisions based on test results, ultimately leading to better patient outcomes.
