A nurse is contributing a nutritional plan of care for a child. Which of the following diagnostic tests should the nurse recommend for the child?

Cardiac enzymes

Complete blood count

Blood coagulation tests

Arterial blood gases

Answer and Explanation

The Correct Answer is B

A. Cardiac enzymes. Cardiac enzyme tests are used to assess heart damage, such as in myocardial infarction, and are not typically relevant in evaluating a child's nutritional status.

B. Complete blood count. A CBC is a key diagnostic test for assessing nutritional status, as it can reveal anemia (low hemoglobin and hematocrit), infection (elevated white blood cells), and overall health status. It helps identify deficiencies in iron, folate, and vitamin B12, which are common nutritional concerns in children.

C. Blood coagulation tests. Coagulation tests (e.g., PT, INR, aPTT) are used to assess blood clotting disorders and monitor anticoagulant therapy, but they are not standard tests for nutritional assessment unless there is suspicion of a vitamin K deficiency.

D. Arterial blood gases. ABG tests assess respiratory function and acid-base balance, which are more relevant in critically ill patients. They are not routinely used to evaluate a child's nutritional status.

Correct Answer is B

Explanation

A. Schedule the child for a follow-up blood test to monitor lead levels over the coming weeks. While ongoing monitoring is important, it is not the immediate priority in a child with extreme lead poisoning. Immediate intervention is needed to manage acute symptoms and prevent further complications.

B. Provide supportive care to manage common symptoms of nausea and pain. This is the correct first action. Severe lead poisoning can cause neurological and gastrointestinal symptoms, including abdominal pain, vomiting, and irritability. Supportive care addresses these symptoms while preparing for further interventions like chelation therapy.

C. Promote a balanced diet rich in calcium and iron to help mitigate lead absorption. Nutritional support is beneficial in mild to moderate cases, as calcium and iron reduce lead absorption, but it is not the first priority in extreme poisoning. Immediate medical treatment takes precedence.

D. Notify the health department to investigate potential lead exposure sources. Identifying the source of lead exposure is crucial for long-term prevention, but in cases of severe poisoning, immediate medical care is the priority before environmental interventions.

A. "Screening involves a combination of parent interviews, observations, and standardized developmental screening tools." B. "ASD can be definitively diagnosed with a simple blood test, so we will schedule one for your child." C. "The screening process for ASLs usually completed in one visit to the healthcare provider." D. "If your child makes eye contact with you we can rule out autism spectrum disorder."

Correct Answer is A

Explanation

A. "Screening involves a combination of parent interviews, observations, and standardized developmental screening tools." The diagnosis of autism spectrum disorder (ASD) is based on behavioral assessments, including parent-reported history, clinical observations, and standardized screening tools such as the Modified Checklist for Autism in Toddlers (M-CHAT).

B. "ASD can be definitively diagnosed with a simple blood test, so we will schedule one for your child." There is no blood test or biomarker that can diagnose ASD. Diagnosis is based on behavioral and developmental criteria rather than laboratory tests.

C. "The screening process for ASD is usually completed in one visit to the healthcare provider." ASD screening and diagnosis require multiple evaluations over time, often involving developmental specialists, psychologists, and speech therapists to get a comprehensive understanding of the child’s behaviors.

D. "If your child makes eye contact with you, we can rule out autism spectrum disorder." While reduced eye contact is a common characteristic of ASD, some children with ASD do make eye contact, and the presence or absence of this behavior alone does not confirm or rule out the disorder.
