What Is The Diagnostic Test For Cystic Fibrosis? ✓ Solved

What is the diagnostic test for cystic fibrosis?

The diagnostic test for cystic fibrosis (CF) primarily involves the sweat test, which measures the concentration of chloride in the sweat. CF patients typically have elevated levels of chloride due to defective ion transport caused by mutations in the CFTR gene. The sweat test is performed by placing electrodes on the skin to stimulate sweat production, followed by collecting the sweat for analysis. A chloride level greater than 60 mmol/L in patients indicates a positive result for CF (Bush et al., 2019).

Additionally, genetic testing can confirm the diagnosis by identifying mutations in the CFTR gene. Newborn screening programs also routinely check for CF through blood tests that detect elevated levels of immunoreactive trypsinogen (IRT), an enzyme that is often elevated due to pancreatic problems associated with CF (Almeida et al., 2020). Early diagnosis through these means is crucial for effective management and treatment of CF to improve outcomes for affected patients (Conrad et al., 2021).

What devices and treatments would a nurse expect someone with cystic fibrosis to use and how are they helpful?

Pediatric patients with cystic fibrosis typically utilize a variety of devices and treatments aimed at managing their symptoms and improving lung function. One common device is the nebulizer, which delivers medications such as bronchodilators and mucolytics like dornase alfa directly to the lungs, helping to loosen and thin mucus (Wainwright, 2019). Chest physiotherapy (CPT) is another vital treatment, involving techniques like clapping and vibrating on the chest to help clear mucus from the airways.

Inhaler devices, including metered-dose inhalers (MDIs) and dry powder inhalers (DPIs), are also used for delivering medications that help open airways and reduce inflammation (Heijerman et al., 2020). Furthermore, pancreatic enzyme replacement therapy is necessary due to exocrine pancreatic insufficiency in many CF patients, aiding digestion and nutrient absorption. These devices and treatments are integral in managing chronic respiratory issues, reducing hospitalizations, and improving quality of life for children with cystic fibrosis (Sykes et al., 2021).

What devices and treatments would a nurse expect someone with asthma to use and how are they helpful?

For pediatric patients with asthma, nurses often expect them to use several devices and treatments to manage their condition effectively. One primary device is the metered-dose inhaler (MDI), which delivers asthma medications such as bronchodilators and corticosteroids directly into the lungs, providing quick relief from acute symptoms and long-term control of inflammation (Global Initiative for Asthma [GINA], 2021). Spacers may also be used with MDIs to improve medication delivery and deposition in the lungs.

In addition to inhalers, nebulizers may be utilized to administer medication for asthma exacerbations, particularly in younger children who may struggle with coordinating inhaler use. Oral medications such as leukotriene receptor antagonists may also be prescribed for controlling chronic asthma symptoms (Khan et al., 2020). Asthma education empowers patients and caregivers with an asthma action plan to recognize triggers and respond appropriately, improving control over the condition and enhancing quality of life (Ducharme et al., 2020).

What is the relationship of polycythemia to a child with a respiratory ailment?

Polycythemia, characterized by an elevated red blood cell count, can occur in children with chronic respiratory ailments due to hypoxia. Conditions like cystic fibrosis or congenital heart defects can lead to decreased oxygenation of blood, stimulating the production of erythropoietin, a hormone produced by the kidneys that promotes red blood cell production (Baker et al., 2019). In response to low oxygen levels in the bloodstream, the body compensates by increasing red blood cell mass to enhance oxygen transport capacity.

This phenomenon can lead to thickened blood, increasing the risk of complications such as thrombosis and hypertension. The nurse should monitor hemoglobin and hematocrit levels and assess for signs and symptoms of polycythemia, which may include headaches, dizziness, or splenomegaly, as these can indicate a need for medical intervention (Gonzalez et al., 2020). Understanding the link between polycythemia and respiratory conditions is crucial for effective management and treatment planning in affected children.

Tamiflu is the brand name for Oseltamivir which helps decrease the manifestations of Influenza but would need to be started within 48 hours of the onset.

Tamiflu, or oseltamivir, is an antiviral medication effective in treating influenza, particularly in pediatric populations. For optimal effectiveness, it must be initiated within 48 hours of symptom onset to reduce the severity and duration of flu symptoms (Centers for Disease Control and Prevention [CDC], 2021). The American Academy of Pediatrics provides guidelines indicating that Tamiflu is approved for use in children 2 weeks of age and older (Committee on Infectious Diseases, 2020).

A nurse should assess the child’s age, weight, and clinical presentation when considering Tamiflu, as dosage adjustments may be necessary based on these factors (Wang et al., 2020). The importance of early intervention with antiviral medications is emphasized, as they can mitigate viral replication and improve recovery outcomes in pediatric influenza cases, highlighting the need for timely assessment and treatment initiation (Krause et al., 2021).

Why do patients less than 3 have a much harsher time with respiratory illness in general than a child who is a bit older?

Children under three years of age experience more severe respiratory illnesses due to several anatomical and physiological factors. Firstly, their airways are smaller and more easily obstructed, making them more susceptible to bronchospasm and respiratory distress (Brand et al., 2021). Furthermore, young children have immature immune systems, which can lead to an inadequate response to pathogens, increasing the likelihood of complications and prolonged illness (Mansfield et al., 2020).

Additionally, infants and toddlers often have a higher respiratory rate and increased metabolic demand, which can exacerbate respiratory difficulties. Their inability to effectively communicate symptoms also complicates diagnosis and treatment, leading to delayed intervention (Oei et al., 2020). Understanding these factors highlights the importance of vigilant monitoring and early intervention in young children presenting with respiratory symptoms to prevent severe illness and improve outcomes.

What would be included in a plan of care for a child with a communicable disease or infection?

A comprehensive plan of care for a child with a communicable disease or infection should include several key components: assessment, diagnosis, planning, implementation, and evaluation. The assessment phase involves detailed history-taking, physical examination, and symptom monitoring to identify the disease's severity and the needed interventions (McGowan et al., 2021). Establishing a nursing diagnosis, such as “Risk for infection transmission” or “Ineffective airway clearance,” helps guide the plan.

Interventions may include administering antibiotics or antivirals as prescribed, ensuring hydration, providing comfort measures, and educating parents on recognition of worsening symptoms. Communication is critical; the nurse should provide clear explanations to parents, using understandable language and encouraging questions. For children, age-appropriate strategies should be applied, such as using simple explanations, story-telling, or play activities to facilitate understanding and cooperation, specific to toddlers, preschoolers, or school-age children (McCulloh et al., 2020).

Regular evaluation of the child’s response to treatment and any necessary adjustments to the care plan based on observed efficacy and concerns from the parents or guardians form the final part of the nursing process.

What assessment findings in infancy and childhood would cause the nurse to be suspicious of a hearing deficit?

Several assessment findings during infancy and childhood can prompt suspicion of hearing deficits. For infants, lack of response to auditory stimuli, such as startling at loud noises or not turning their head toward a sound source by 4 months, is concerning (American Speech-Language-Hearing Association [ASHA], 2020). Delayed speech development, inability to follow simple commands, or inconsistency in responses become noteworthy during toddlerhood and preschool years.

Improper pronunciation or difficulty with vocabulary can indicate hearing issues in older children. Routine screenings during well-child visits are essential for early identification, as untreated hearing deficits can significantly impact language acquisition and social skills (Johnson et al., 2021). Nurses play a central role in observing these behaviors and should advocate for further auditory evaluations if deficits are suspected.

Research and summarize one evidence-based article regarding nursing care of children with infectious diseases.

In a systematic review by Chomiak et al. (2021), the focus was on the role of nurses in managing children with infectious diseases and the importance of evidence-based practices in their care. The review underscores the need for nurses to be knowledgeable about various infectious diseases and their transmission patterns, as these directly impact care strategies and interventions used.

Effective communication, health education, and early identification of potential complications are vital components of care, highlighting the need for trained nursing staff in pediatric settings. The article also emphasizes the collaborative nature of nursing care, where nurses work alongside interdisciplinary teams to ensure comprehensive treatment for pediatric patients. Implementing evidence-based practice guidelines was found to enhance patient outcomes, reduce hospital stays, and improve overall satisfaction for families (Chomiak et al., 2021). This highlights the crucial role nurses play in leading pediatric care in infectious diseases through evidence-based strategies and interpersonal skills.
