A nurse is caring for a 40-year-old female client in an outpatient clinic.
Which of the following primary skin lesions contain fluid?
Papule
Nodule
Vesicle
Pustule
Tumor
Wheal
Macule
Correct Answer : C,D
Choice A rationale: Papules are small, raised, solid skin lesions less than 1 cm in diameter. They do not contain fluid; instead, they consist of thickened epidermis or dermal infiltrates. Papules are common in conditions like psoriasis and dermatitis, but their solid nature distinguishes them from fluid-filled lesions.
Choice B rationale: Nodules are larger, solid, raised lesions extending deeper into the dermis or subcutaneous tissue, typically more than 1 cm. They do not contain fluid but represent firm tissue masses seen in conditions such as rheumatoid nodules or lipomas.
Choice C rationale: Vesicles are small, fluid-filled lesions less than 1 cm in diameter, containing clear serous fluid. They appear as raised, translucent blisters and are characteristic of conditions like herpes simplex virus infection or contact dermatitis, matching the client’s fluid-filled itchy rash.
Choice D rationale: Pustules are raised lesions similar to vesicles but filled with purulent material (pus), indicating localized infection or inflammation. They appear white or yellow and are typical in conditions like acne or impetigo, representing a fluid-filled primary lesion.
Choice E rationale: Tumors are large solid masses that extend deeper into the dermis or subcutaneous tissues, usually more than 2 cm in diameter. They do not contain fluid and represent neoplasms or benign growths such as lipomas or cysts.
Choice F rationale: Wheals are transient, elevated, erythematous, and edematous lesions caused by dermal edema. They do not contain fluid in a cavity but represent swelling in the skin layers, typical of urticaria or allergic reactions.
Choice G rationale: Macules are flat, non-palpable skin color changes less than 1 cm in size. They do not contain fluid and are seen in conditions like freckles or petechiae.

Correct Answer is ["0.7"]
Explanation
Step 1: Convert the child's weight from pounds to kilograms. 58 pounds ÷ 2.2 pounds/kg = 26.36 kg.
Step 2: Calculate the total milligrams of methylprednisolone needed per dose. 1 mg/kg × 26.36 kg = 26.36 mg.
Step 3: Determine the volume in mL to administer per dose. 26.36 mg ÷ (40 mg/mL) = 0.659 mL.
Step 4: Round the volume to the nearest tenth. 0.7 mL. The final calculated answer is 0.7 mL.
Correct Answer is C
Explanation
Choice A rationale
Otitis media is an inflammation of the middle ear, typically presenting with ear pain, fever, and sometimes discharge. While a tuning fork might be used in a general ear examination, its primary role is not in diagnosing otitis media, which relies more on otoscopic visualization of the tympanic membrane and clinical signs.
Choice B rationale
Tinnitus is the perception of ringing or buzzing in the ears, often a symptom of an underlying condition rather than a disease itself. While a client with tinnitus might have hearing loss, the tuning fork is used to *assess* hearing, not specifically to diagnose or characterize the subjective experience of tinnitus.
Choice C rationale
A tuning fork is a calibrated instrument used to assess hearing loss, specifically to differentiate between conductive and sensorineural hearing deficits. The Weber and Rinne tests, performed with a tuning fork, provide valuable information about how sound is transmitted through the ear and perceived by the auditory nerve.
Choice D rationale
While some neurological conditions can affect hearing, the tuning fork's direct application in a physical examination is for auditory assessment. Neurological pathology is primarily assessed through a comprehensive neurological examination, including cranial nerve assessments, reflexes, and motor and sensory function, rather than relying solely on a tuning fork.
