Which disease causes a classic butterfly rash over cheeks and bridge of nose (malar rash), which looks like a sunburn?

Psoriasis.

Eczema.

Systemic Lupus Erythematosus.

Acne vulgaris.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Psoriasis is a chronic autoimmune skin condition characterized by red, scaly patches (plaques) with well-defined borders, often on extensor surfaces like elbows and knees. It does not typically manifest as a butterfly-shaped rash on the face, differentiating it from the specified presentation.

Choice B rationale

Eczema (atopic dermatitis) is an inflammatory skin condition presenting with itchy, red, and sometimes weeping or crusted patches. While it can affect the face, its distribution and appearance do not typically form the classic butterfly-shaped malar rash described.

Choice C rationale

Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease characterized by systemic inflammation. A classic dermatological manifestation is the "malar rash" or "butterfly rash" over the cheeks and bridge of the nose, resembling a sunburn, which is highly characteristic of the disease.

Choice D rationale

Acne vulgaris is a common skin condition involving inflammation of hair follicles and sebaceous glands, leading to comedones, papules, pustules, and cysts. It typically affects the face, chest, and back but does not present as a distinct butterfly-shaped erythematous rash.

Correct Answer is ["100"]

Explanation

Step 1: Calculate mL per minute. 100 mL ÷ 60 min = 1.666. mL/min.

Step 2: Multiply mL per minute by the drop factor. 1.666. mL/min × 60 gtt/mL = 100 gtt/min. The nurse should set the IV flow rate to deliver 100 gtt/min.

A. Avoid the use of warm water to wash the client's face. B. Apply an eye patch to the client's right eye. C. Place suction equipment at the client's bedside. D. Provide range-of-motion exercises to the client's neck and shoulders.

Correct Answer is C

Explanation

Choice A rationale

Avoiding warm water for facial washing is generally unrelated to cranial nerve IX (glossopharyngeal) or X (vagus) impairment. These nerves primarily affect swallowing, gag reflex, and vocal cord function, not facial sensation or hygiene temperature responses. Facial sensation is predominantly mediated by the trigeminal nerve (CN V), and facial motor control by the facial nerve (CN VII).

Choice B rationale

Applying an eye patch to the right eye is indicated for impairment of the facial nerve (CN VII) or trigeminal nerve (CN V), which can lead to lagophthalmos or corneal abrasions due to incomplete eyelid closure or decreased sensation. Acoustic neuroma primarily affects CN VIII, but its growth can sometimes impinge on adjacent nerves, including CNs V and VII. However, the question specifically mentions CN IX and X impairment.

Choice C rationale

Impairment of cranial nerves IX (glossopharyngeal) and X (vagus) significantly affects the gag reflex and swallowing mechanisms, increasing the risk of aspiration. The glossopharyngeal nerve is crucial for the afferent limb of the gag reflex and initiates swallowing, while the vagus nerve controls pharyngeal and laryngeal muscles. Therefore, having suction equipment readily available is a critical safety measure to manage potential aspiration events and maintain airway patency.

Choice D rationale

Providing range-of-motion exercises to the client's neck and shoulders addresses musculoskeletal concerns and is not directly related to the physiological deficits caused by impairment of cranial nerves IX and X. These nerves are involved in functions like speech, swallowing, and parasympathetic regulation, not in the motor control of the neck and shoulder musculature, which is primarily managed by cervical spinal nerves and the accessory nerve (CN XI).
