While assessing a client, a nurse detects a bluish tinge to the client's palms, soles, and mucous membranes. Which action should the nurse take next?

Correct Answer: B

Rationale: The correct answer is B: Use pulse oximetry to assess the client's oxygen saturation. The bluish tinge, known as cyanosis, indicates decreased oxygen saturation in the blood. Using pulse oximetry will provide objective data on the client's oxygen levels. This is crucial in determining the severity of hypoxemia and guiding further interventions. Choice A: Asking about medications is not the immediate priority when cyanosis is detected. Medications may be relevant but do not address the urgent need for assessing oxygen saturation. Choice C: Auscultating lung fields is important in assessing respiratory status, but it does not directly address the need to determine the client's oxygen saturation level. Choice D: Palpating pulses can provide information on perfusion, but it does not directly assess the client's oxygenation status, which is the immediate concern when cyanosis is present.

Correct Answer: A

Rationale: The correct answer is A: Cool, moist compresses. This nonpharmacologic measure helps to soothe eczematous dermatitis by reducing inflammation, itching, and discomfort. Cool compresses provide relief by constricting blood vessels and reducing swelling. Moist compresses help to hydrate the skin and prevent further irritation. Summary: B: Topical corticosteroids are pharmacologic agents used to treat eczematous dermatitis by reducing inflammation. They are not nonpharmacologic comfort measures. C: Heating pad can exacerbate eczematous dermatitis by increasing inflammation and itching. It is not recommended for this condition. D: Tepid bath with cornstarch may provide some relief for eczematous dermatitis, but cool, moist compresses are more effective in soothing the skin and reducing discomfort.

Correct Answer: C

Rationale: The correct answer is C: Full thickness. This categorization is based on the description of white and leather-like appearance, indicating complete destruction of the epidermis and dermis layers. This type of injury is characteristic of full-thickness burns, also known as third-degree burns. Partial-thickness deep burns (A) involve damage to the dermis but not the full thickness, while partial-thickness superficial burns (B) only affect the epidermis and part of the dermis. Superficial burns (D) are limited to the epidermis only. The specific description of the burns in this case clearly aligns with full-thickness burns, making choice C the most appropriate categorization.

Correct Answer: D

Rationale: The correct answer is D because staying out of the sun between 10 AM and 2 PM reduces exposure to the strongest UV rays, decreasing the risk of skin damage. A is incorrect as SPF should be at least 30. B is wrong as water-resistant sunscreens require reapplication after swimming. C is incorrect as increasing sun exposure can lead to more skin damage. In summary, option D is the most effective in reducing sun damage risk compared to the other choices.

Correct Answer: D

Rationale: The correct answer is D: Ask the patient to describe the impact of psoriasis on quality of life. This is the first action the nurse should take to understand the patient's perspective, feelings, and how psoriasis is affecting their daily life. By doing so, the nurse can assess the severity of the social withdrawal and emotional impact, which can guide further interventions. Choice A is incorrect because enrolling in a worker-retraining program does not address the immediate social withdrawal and emotional impact due to psoriasis. Choice B is incorrect as encouraging the patient to volunteer for community projects may not be suitable or effective in addressing the patient's current emotional distress. Choice C is incorrect because suggesting cosmetics to cover the lesions only focuses on the physical appearance and does not address the underlying emotional and social issues.
