Correct Answer: C
Rationale: Step 1: The key information here is an irritated, erythematous area on Mrs. Stevens' left hand. Step 2: The most likely cause is contact dermatitis, often triggered by changes in dish detergent. Step 3: Therefore, it is crucial to first determine if she changed her dish detergent recently. Step 4: If the detergent is the cause, changing back to the previous one can resolve the issue. Summary: - A: Food allergies usually manifest differently and are less likely to cause localized skin irritation. - B: Anaphylaxis presents with severe symptoms like difficulty breathing, not just skin irritation. - D: Strange animals are unlikely to cause localized skin irritation unless a specific allergy is known.
Question 2 of 5
In planning Mr. Baker’s daily care, you wish to give him as much independence and control as possible. In relation to a required dressing change, which would be an appropriate question to ask?
Correct Answer: D
Rationale: The correct answer is D: "Would you like to have your dressing changed now or at 11:00 A.M.?" This question allows Mr. Baker to choose the timing of the dressing change, promoting his independence and control over his care. By giving him options, it respects his autonomy and preferences. Choice A is not as appropriate because it only offers one option for the timing of the dressing change, limiting Mr. Baker's control. Choice B is more focused on the method of dressing change rather than the timing, which is not directly related to promoting independence. Choice C introduces an unnecessary element of bravery and medication, which may not be relevant or respectful of Mr. Baker's autonomy in this context.
Question 3 of 5
Some cells in the subcutaneous tissue produce histamine, which contributes to the process of:
Correct Answer: D
Rationale: The correct answer is D: inflammation. Histamine is released by cells in response to injury or allergens, leading to vasodilation and increased permeability of blood vessels, causing redness and swelling - classic signs of inflammation. Inflammation is a protective response that helps the body to eliminate harmful stimuli and initiate the healing process. Choices A, B, and C are incorrect because histamine does not play a role in infection, mitosis, or energy storage.
Question 4 of 5
Which statement is NOT true of the dermis?
Correct Answer: A
Rationale: The correct answer is A because the papillary layer of the dermis actually anchors the epidermis to the dermis, not the dermis to the subcutaneous tissue. The papillary layer contains blood vessels, nerves, and touch receptors. Choice B is correct because hair follicles are indeed found in the dermis, providing nourishment to hair. Choice C is incorrect because the secretory portions of sebaceous glands are actually located in the subcutaneous layer, not the dermis. Choice D is incorrect because many cutaneous receptors, such as Meissner's corpuscles and Pacinian corpuscles, are located in the dermis, responsible for sensations like touch and pressure.
Question 5 of 5
The healthcare provider has ordered Collagenase for a patient with a left leg necrotic ulcer. What does the nurse understands about the use of collagenase?
Correct Answer: C
Rationale: The correct answer is C because Collagenase speeds up the rate at which necrotic tissue is removed by breaking down collagen within the necrotic tissue. This enzyme helps to debride the wound and promote healing. Choice A is incorrect as collagenase does not absorb exudates. Choice B is incorrect because collagenase is not the body's own digestive enzymes. Choice D is incorrect because collagenase does not remove exudate through high moisture-vapor transmission rate.
