The nurse in an allergy clinic is educating a new patient about the pathology of the patients health problem. What response should the nurse describe as a possible consequence of histamine release?

Correct Answer: B

Rationale: The correct answer is B: Contraction of bronchial smooth muscle. Histamine release can lead to bronchoconstriction, which narrows the airways and causes difficulty in breathing. This is a common symptom in allergic reactions like asthma. Constriction of small venules (Choice A) is not a typical consequence of histamine release. Dilation of large blood vessels (Choice C) is more associated with histamine's role in increasing vascular permeability. Decreased secretions from gastric and mucosal cells (Choice D) is not directly related to histamine's effects on smooth muscle contraction.

Correct Answer: D

Rationale: The correct answer is D: Asthma. Atopic dermatitis is associated with a heightened immune response and inflammation, which can predispose individuals to developing asthma. Both conditions involve an overactive immune response and can coexist in patients due to shared genetic and environmental factors. Asthma commonly presents alongside atopic dermatitis in individuals with atopic tendencies. Bronchitis (choice A) is a respiratory condition caused by inflammation of the bronchial tubes and is not directly linked to atopic dermatitis. Systemic lupus erythematosus (choice B) and rheumatoid arthritis (choice C) are autoimmune diseases that primarily affect the joints and other organs, but they are not typically associated with atopic dermatitis.

Correct Answer: B

Rationale: The correct answer is B. Antihistamines are generally considered safe during pregnancy, but it is recommended to avoid unnecessary medications, especially in the third trimester. Antihistamines should be used cautiously in pregnant women due to potential effects on the fetus. Choice A is incorrect because previous treatment for tuberculosis does not contraindicate the use of antihistamines. Choice C is incorrect as estrogen-replacement therapy does not interact significantly with antihistamines. Choice D is incorrect as a severe allergy to eggs does not directly contraindicate the use of antihistamines.

Correct Answer: B

Rationale: The correct answer is B: Refer the woman to her primary care provider to have the medication changed. Rationale: 1. Rash after taking the first dose of an antibiotic suggests a possible allergic reaction. 2. Allergic reactions can range from mild to severe, including anaphylaxis. 3. It is crucial to discontinue the suspected medication to prevent worsening of the reaction. 4. Referring the patient to their primary care provider ensures proper evaluation and management. 5. Changing the medication is necessary to avoid potential harm from continued exposure. Summary: A: Continuing the medication can worsen the allergic reaction and is not recommended. C: Going to the emergency department may be excessive at this point for a mild rash. D: Taking an antihistamine does not address the underlying issue of an allergic reaction.

Correct Answer: A

Rationale: The correct answer is A: Wear a medical identification bracelet. This is important because in case of an emergency, such as an allergic reaction, medical professionals need to be aware of the child's severe food allergy quickly. The bracelet provides crucial information that can help in providing timely and appropriate medical care. B: Knowing how to use the antihistamine pen is also important in managing allergic reactions, but wearing a medical identification bracelet takes precedence as it provides immediate identification of the allergy. C: Knowing how to give injections of lidocaine is not relevant to managing a food allergy in a child. D: Avoiding live attenuated vaccinations may be necessary for individuals with certain allergies, but it is not directly related to educating parents about managing the child's food allergy.
