foundations of nursing practice questions Questions
Question 1 of 5
A patient with a family history of allergies has suffered an allergic response based on a genetic predisposition. This atopic response is usually mediated by what immunoglobulin?
Correct Answer: D
Rationale: The correct answer is D: Immunoglobulin E. The atopic response in allergies is mainly mediated by IgE antibodies. IgE binds to allergens and triggers the release of histamine and other chemicals that cause allergic symptoms. IgA is mainly found in mucosal areas, IgM is involved in early immune responses, and IgG is important for long-term immunity. IgE is specifically associated with allergic reactions due to its role in sensitizing mast cells and basophils to allergens.
Question 2 of 5
A patient has been admitted to the emergency department with signs of anaphylaxis following a bee sting. The nurse knows that if this is a true allergic reaction the patient will present with what alteration in laboratory values?
Correct Answer: A
Rationale: The correct answer is A: Increased eosinophils. Eosinophils are a type of white blood cell involved in allergic reactions. During anaphylaxis, the body releases chemicals that stimulate the production and activation of eosinophils, leading to an increase in their count. This helps in the identification of an allergic reaction. Incorrect Choices: B: Increased neutrophils - Neutrophils are not specific to allergic reactions and are typically increased in bacterial infections. C: Increased serum albumin - Serum albumin levels are not directly affected by allergic reactions. D: Decreased blood glucose - Hypoglycemia is not a typical manifestation of an allergic reaction.
Question 3 of 5
The nurse is planning the care of a patient who has a diagnosis of atopic dermatitis, which commonly affects both of her hands and forearms. What risk nursing diagnosis should the nurse include in the patients care plan?
Correct Answer: D
Rationale: The correct answer is D: Risk for Self-Care Deficit Related to Skin Lesions. Patients with atopic dermatitis may experience difficulty performing self-care tasks due to pain, itching, and limitations in hand mobility caused by skin lesions. This diagnosis addresses the potential challenges the patient may face in maintaining personal hygiene and managing their skin condition. Explanation for why other choices are incorrect: A: Risk for Disturbed Body Image Related to Skin Lesions - While atopic dermatitis may impact body image, the priority in this case is the patient's ability to perform self-care. B: Risk for Disuse Syndrome Related to Dermatitis - Disuse syndrome is not typically associated with atopic dermatitis. C: Risk for Ineffective Role Performance Related to Dermatitis - This diagnosis focuses on the patient's ability to fulfill their roles, which may not be directly impacted by atopic dermatitis.
Question 4 of 5
A patient has been living with seasonal allergies for many years, but does not take antihistamines, stating, When I was young I used to take antihistamines, but they always put me to sleep. How should the nurse best respond?
Correct Answer: C
Rationale: Rationale for Correct Answer (C): 1. The newer antihistamines, such as second-generation antihistamines like loratadine or cetirizine, are designed to cause less sedation compared to older antihistamines like diphenhydramine. 2. These newer antihistamines have a lower affinity for crossing the blood-brain barrier, reducing the sedative effects. 3. Therefore, suggesting that the newer antihistamines are different and cause less sedation is the best response to address the patient's concerns. Summary of Incorrect Choices: A. While some newer antihistamines may be combined with decongestants to offset drowsiness, this is not a consistent feature of all newer antihistamines. B. Developing tolerance to sedation after a few months is not a common or reliable response to antihistamines. D. Taking antihistamines at bedtime may help with sedation, but it does not address
Question 5 of 5
A patient has sought care, stating that she developed hives overnight. The nurses inspection confirms the presence of urticaria. What type of allergic hypersensitivity reaction has the patient developed?
Correct Answer: A
Rationale: The correct answer is A: Type I hypersensitivity reaction. This type of reaction involves the release of histamine from mast cells and basophils, leading to symptoms like hives. It is characterized by the involvement of IgE antibodies. In this case, the patient developed hives quickly after exposure to the allergen, indicating an immediate hypersensitivity reaction typical of Type I. Choices B, C, and D are incorrect because they are associated with different mechanisms and timeframes of hypersensitivity reactions. Type II involves antibody-mediated cell destruction, Type III involves immune complex deposition, and Type IV is a delayed-type hypersensitivity reaction mediated by T cells, none of which are consistent with the rapid onset of hives seen in this patient.
