Conjunctivitis medicamentosa is a consequence of chronic use of

Correct Answer: C

Rationale: In this question from the Pediatric NCLEX Practice Quiz, the correct answer is C) decongestants. Conjunctivitis medicamentosa, also known as rebound conjunctivitis, is a condition that can occur as a result of chronic use of decongestant eye drops. Decongestants work by constricting blood vessels in the eye to reduce redness and swelling. Prolonged use of decongestant eye drops can lead to a rebound effect where the blood vessels dilate excessively, causing redness, irritation, and inflammation of the conjunctiva, leading to conjunctivitis. Option A) antihistamines are not typically associated with conjunctivitis medicamentosa as they work by blocking histamine receptors to reduce allergic symptoms. Option B) steroids are not commonly linked to this condition. Steroids are anti-inflammatory agents that work by suppressing the immune response and reducing inflammation. Option D) anti-inflammatory medications, which may include non-steroidal anti-inflammatory drugs (NSAIDs), are not typically the cause of conjunctivitis medicamentosa. These medications reduce inflammation by inhibiting the production of certain chemicals in the body. Educationally, understanding the adverse effects of commonly used medications is crucial for nursing students preparing for the NCLEX exam. This question highlights the importance of recognizing side effects associated with specific drug classes and the significance of patient education to prevent such complications. Nurses must be vigilant in monitoring patients for signs of adverse drug reactions and educating them on proper medication use to prevent complications like conjunctivitis medicamentosa.

Correct Answer: A

Rationale: In this question, the correct answer is A) Heiner syndrome. Heiner syndrome is a non-IgE-mediated food allergy that typically presents as pulmonary hemosiderosis in infants and is associated with cow's milk consumption. This is the correct answer because non-IgE-mediated food allergies involve immune responses that do not involve IgE antibodies. Option B) gastrointestinal anaphylaxis is incorrect because it refers to a severe allergic reaction in the gastrointestinal tract that typically involves IgE antibodies. Option C) rhinoconjunctivitis is incorrect as it is a form of allergic rhinitis that involves IgE-mediated reactions in the nasal and ocular mucosa. Option D) oral allergy syndrome is also incorrect as it is a condition where individuals experience allergic reactions to certain fresh fruits, vegetables, and nuts due to cross-reactivity with pollen allergens. This is typically IgE-mediated. Understanding the different types of food allergies and their mechanisms is crucial for healthcare professionals caring for pediatric patients. Recognizing the distinctions between IgE-mediated and non-IgE-mediated food allergies can help guide appropriate diagnostic testing and management strategies for these conditions. It is important for nurses and other healthcare providers to be able to differentiate between various food allergy presentations to provide safe and effective care to pediatric patients.

Correct Answer: B

Rationale: Cutaneous lupus is a form of lupus that primarily affects the skin. Sulfonamides are implicated in causing drug-induced cutaneous lupus erythematosus (CLE). Sulfonamides like sulfamethoxazole are known triggers for CLE due to their ability to induce an autoimmune response in susceptible individuals. Corticosteroids (Option A) are not typically associated with causing cutaneous lupus; in fact, they are commonly used in the treatment of lupus to suppress inflammation. Allopurinol (Option C) is a xanthine oxidase inhibitor used to treat gout and hyperuricemia, and it is not known to cause cutaneous lupus. Beta-lactam antibiotics (Option D) are not commonly implicated in causing cutaneous lupus either. In an educational context, understanding the potential triggers for cutaneous lupus is important for healthcare providers, especially those working with pediatric patients. By knowing which medications can induce this condition, healthcare providers can make informed decisions when prescribing medications to children with lupus or at risk for developing lupus. This knowledge can help in preventing adverse reactions and managing the condition effectively.

Correct Answer: D

Rationale: In this question, the correct answer is D) 50%. When one parent has allergies, there is a 50% chance that their child will develop an allergic disease. This is due to the inheritance of atopic traits, which can predispose individuals to allergic conditions. Option A) 15%, Option B) 25%, and Option C) 35% are incorrect because they underestimate the likelihood of a child developing allergies when one parent is affected. Allergies often have a strong genetic component, and the risk is higher than the percentages provided in these options. Educationally, understanding the link between family history and the development of allergic diseases is crucial for healthcare professionals, especially in pediatric care. Recognizing this relationship can aid in early identification, prevention, and management of allergies in children. It also highlights the importance of taking a detailed family history when assessing pediatric patients with suspected allergic conditions.

Correct Answer: D

Rationale: In the context of reducing exposure to dust mites, the correct action is to remove carpets from the bedroom and play areas (Option D). Dust mites thrive in carpets, and removing them can significantly reduce the allergen load in the environment. Carpets trap dust, skin flakes, and other particles that serve as food for dust mites, making them a breeding ground for these allergens. Option A, encasing pillows and mattresses in allergen-impermeable encasements, is also an essential action to reduce exposure to dust mites. However, this alone may not be as effective as removing carpets, which are a major reservoir for dust mites. Options B and C are not directly related to reducing exposure to dust mites. While avoiding sleeping or lying on upholstered furniture may help reduce exposure to other allergens like pet dander or pollen, it is not as effective for dust mites. Similarly, while minimizing stuffed toys can help reduce dust accumulation in the bedroom, it is not as critical as removing carpets, which are a primary habitat for dust mites. In an educational context, understanding the importance of environmental modifications in reducing exposure to allergens like dust mites is crucial for healthcare professionals working with pediatric populations. By prioritizing actions like removing carpets and using allergen-impermeable encasements, healthcare providers can better support families in managing allergies and asthma in children.
