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?

  • A. Constriction of small venules
  • B. Contraction of bronchial smooth muscle
  • C. Dilation of large blood vessels
  • D. Decreased secretions from gastric and mucosal cells
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.
