The skin of patients with atopic dermatitis exhibits all of the following EXCEPT

Correct Answer: D

Rationale: In pediatric nursing, understanding atopic dermatitis is crucial for providing effective care to children. In this case, the correct answer is D) blanching after intradermal histamine injection. This is because atopic dermatitis is associated with an increased response to histamine, leading to blanching upon injection due to increased capillary permeability. Option A) Wheel and flare reaction after intradermal injection of an allergen is often seen in patients with atopic dermatitis due to their hyperreactivity to allergens, making it a common feature of the condition. Option B) White dermographism refers to the skin reaction where pressure on the skin leads to white lines, which can be present in patients with atopic dermatitis due to their skin hypersensitivity. Option C) Abnormal rates of cooling are not specific to atopic dermatitis and are not a characteristic feature of this condition. Educationally, understanding these skin manifestations in atopic dermatitis helps nurses in early identification, management, and education of patients and families. By differentiating these skin responses, nurses can provide tailored care plans and educate on triggers and symptom management effectively.

Correct Answer: C

Rationale: The correct answer is C) Begin seasonal use of topical corticosteroids. Topical corticosteroids are the recommended treatment for allergic rhinitis in children due to their effectiveness in reducing inflammation in the nasal passages. They help alleviate symptoms such as watery rhinorrhea, sneezing, and nasal congestion by targeting the underlying inflammatory response triggered by allergens. Option A) Institute strict measures to avoid outdoor allergen exposure may help reduce symptoms, but it is often impractical to completely avoid allergen exposure, especially for outdoor allergens like pollen. Option B) Beginning seasonal use of sympathomimetic drugs may provide temporary relief of symptoms like nasal congestion, but they do not address the underlying inflammation and are not the first-line treatment for allergic rhinitis in children. Option D) Prescribing amoxicillin for 10 days is not appropriate for allergic rhinitis, as it is an antibiotic used to treat bacterial infections, not allergic reactions. In an educational context, it is crucial for healthcare providers to understand the appropriate management of allergic rhinitis in children to provide optimal care and improve patient outcomes. Topical corticosteroids are safe and effective when used as directed, making them a cornerstone in the treatment of allergic rhinitis in pediatric patients. Understanding the rationale behind the treatment options helps healthcare professionals make informed decisions and provide evidence-based care.

Correct Answer: D

Rationale: Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur rapidly, leading to airway constriction, a drop in blood pressure, and other serious symptoms. In this case, the correct answer is D) Exercise. While exercise-induced anaphylaxis is a real phenomenon, it is not as common as anaphylaxis triggered by foods, drugs, or insect stings. Foods, drugs, and insect stings are more well-known triggers for anaphylaxis in both children and adults. Common food allergens like peanuts, tree nuts, shellfish, and eggs can cause severe allergic reactions. Certain medications, such as antibiotics or nonsteroidal anti-inflammatory drugs (NSAIDs), are also known to trigger anaphylaxis. Additionally, insect stings from bees, wasps, or hornets can lead to anaphylactic reactions in some individuals. In an educational context, understanding the common triggers of anaphylaxis is crucial for healthcare professionals, especially those working with pediatric patients who may have allergies. By knowing the common causes, healthcare providers can be better prepared to recognize and respond to anaphylactic reactions promptly and effectively. This knowledge can help save lives in emergency situations where quick intervention is essential.

Correct Answer: B

Rationale: Insect sting anaphylaxis is a critical topic in pediatric nursing as it can lead to life-threatening situations. The correct answer, B) Mosquitoes, is not a common cause of insect sting anaphylaxis because mosquito stings typically result in local reactions like redness and itching, rather than systemic allergic reactions. A) Honeybees are a common cause of insect sting anaphylaxis due to the venom they inject, which can trigger severe allergic reactions in susceptible individuals. C) Wasps also inject venom that can cause anaphylactic reactions in some people. D) Fire ants are known for their painful stings which can lead to allergic reactions, including anaphylaxis. Educationally, understanding the common causes of insect sting anaphylaxis is crucial for pediatric nurses to provide prompt and effective care in emergency situations. By knowing which insects are more likely to cause severe allergic reactions, nurses can quickly assess, intervene, and prevent escalation of symptoms in pediatric patients who experience insect stings. This knowledge can ultimately save lives and improve patient outcomes.

Correct Answer: A

Rationale: In pediatric nursing, understanding the causes of distributive shock is crucial for providing effective care to critically ill children. Distributive shock is characterized by widespread vasodilation leading to decreased systemic vascular resistance. In this scenario, the correct answer is A) Early sepsis. Early sepsis can cause distributive shock in pediatric patients due to the release of inflammatory mediators triggering widespread vasodilation. This results in poor tissue perfusion and hypotension, leading to shock. Therefore, early recognition and prompt treatment of sepsis are essential in preventing distributive shock in pediatric patients. Option B) Tension pneumothorax causes obstructive shock due to impaired venous return from the heart, leading to decreased cardiac output. It is not a cause of distributive shock. Option C) Cardiac tamponade results in obstructive shock by compressing the heart chambers, impairing cardiac filling and output. It does not cause distributive shock. Option D) Aortic stenosis leads to obstructive shock as it obstructs blood flow out of the heart, reducing cardiac output. It is not a cause of distributive shock. Educationally, understanding the different types of shock and their etiologies is vital for nurses caring for pediatric patients. By grasping the distinct pathophysiological mechanisms underlying each type of shock, nurses can accurately assess and intervene to stabilize a child in shock. This knowledge enhances patient outcomes and underscores the importance of a systematic approach to pediatric nursing care.
