Early introduction of all the following decreases the risk of asthma and allergic rhinitis EXCEPT

Correct Answer: A

Rationale: In this question, the correct answer is A) rye. Early introduction of allergenic foods like fish, egg, and meat has been shown to decrease the risk of asthma and allergic rhinitis in children. However, rye is not typically associated with reducing the risk of these conditions through early introduction. Educationally, understanding the impact of early introduction of allergenic foods on pediatric health is crucial for healthcare providers, especially pediatric nurses. It allows them to provide evidence-based guidance to parents on feeding practices for their children. By knowing which foods can decrease the risk of asthma and allergic rhinitis, nurses can play a vital role in promoting preventive care and overall well-being in pediatric populations. This knowledge empowers nurses to support parents in making informed decisions about their children's diet and potentially reducing the incidence of these conditions.

Correct Answer: B

Rationale: In the management of severe asthma exacerbations in pediatric patients, the MOST vital initial treatment is the administration of inhaled B-agonists. This is the correct answer (option B) because B-agonists, such as albuterol, work by quickly relaxing the airway smooth muscles, providing rapid relief of bronchospasm and improving airflow. This is crucial in managing acute asthma attacks and preventing respiratory failure. Supplemental oxygen (option A) may be necessary for patients with severe asthma exacerbations, but it is not the MOST vital initial treatment. Oxygen therapy is usually provided alongside bronchodilators like B-agonists. Intramuscular injection of epinephrine (option C) is not recommended as a first-line treatment for severe asthma exacerbations in children. Epinephrine is primarily used in managing anaphylaxis, not asthma. Inhaled ipratropium (option D) is another bronchodilator that can be used in conjunction with B-agonists in the treatment of asthma exacerbations, but it is not the MOST vital initial treatment. B-agonists are preferred due to their rapid onset of action and effectiveness in relieving bronchospasm. Educationally, it is essential for pediatric nurses to understand the priority interventions in managing acute asthma exacerbations to provide timely and effective care. By recognizing the importance of inhaled B-agonists as the initial treatment, nurses can help stabilize pediatric patients experiencing severe asthma attacks and prevent further respiratory compromise. Understanding the rationale behind treatment choices is crucial for delivering safe and evidence-based pediatric care.

Correct Answer: A

Rationale: In pediatric nursing, understanding the adverse effects of frequently administered B-agonist therapy in asthma is crucial for safe and effective patient care. In this question, the correct answer is A) bradycardia. Bradycardia is not a typical adverse effect of B-agonist therapy; in fact, B-agonists such as albuterol usually lead to an increase in heart rate (tachycardia) due to their stimulatory effect on beta receptors in the heart. Option B) irritability is a possible adverse effect of B-agonist therapy, as these medications can sometimes cause nervous system stimulation leading to irritability in pediatric patients. Option C) tachycardia is a common adverse effect of B-agonist therapy due to the medication's stimulatory effect on beta receptors in the heart, leading to an increased heart rate. Option D) hypokalemia is another potential adverse effect of B-agonist therapy, as these medications can shift potassium into cells, potentially lowering serum potassium levels. Educationally, it is essential for pediatric nurses to be aware of the potential adverse effects of common asthma medications like B-agonists to monitor patients for any signs of complications. Understanding these effects enables nurses to provide safe and individualized care, monitor for adverse reactions, and intervene promptly if needed to ensure positive patient outcomes.

Correct Answer: C

Rationale: In the context of pediatric nursing, it is essential to understand the differential diagnosis of common conditions like atopic dermatitis. In this case, the correct answer is C) phenylketonuria. Phenylketonuria is a genetic disorder that affects the body's ability to break down the amino acid phenylalanine. It primarily presents with neurological symptoms due to the accumulation of phenylalanine in the body, rather than skin manifestations like atopic dermatitis. Option A) zinc deficiency can present with dermatitis, making it a possible consideration in the differential diagnosis of atopic dermatitis. Option B) pyridoxine deficiency can also present with dermatological symptoms, including a rash, which could be mistaken for atopic dermatitis. Option D) niacin deficiency can lead to a condition called pellagra, which presents with dermatitis in sun-exposed areas, further complicating the diagnosis of atopic dermatitis. Understanding the nuances of these metabolic conditions and their clinical presentations is crucial for pediatric nurses to accurately assess and diagnose pediatric patients. Differential diagnosis skills are fundamental in providing effective care, as they guide appropriate treatment plans and interventions tailored to each child's specific needs.

Correct Answer: D

Rationale: In this question, the correct answer is D) hydrocortisone. Hydrocortisone is the least potent topical steroid used in the treatment of atopic dermatitis. Hydrocortisone is a low-potency corticosteroid that is suitable for use on delicate areas of the skin such as the face, groin, and armpits. It is often recommended for mild cases of atopic dermatitis or for use on children due to its lower potency and decreased risk of side effects compared to stronger steroids. The other options (A) fluticasone, (B) desonide, and (C) betamethasone dipropionate are all more potent topical steroids. Fluticasone, desonide, and betamethasone dipropionate are higher in potency and are typically reserved for more severe cases of atopic dermatitis or for areas of thicker skin where stronger medication may be required. In an educational context, understanding the potency of different topical steroids is crucial for pediatric nurses when managing skin conditions like atopic dermatitis in children. It is important to match the potency of the steroid with the severity of the condition and the age of the patient to ensure effective treatment while minimizing the risk of adverse effects.
