해설
Bilateral parotid gland swelling with associated earache is the hallmark sign of mumps, caused by the mumps virus affecting the salivary glands.
Mumps (epidemic parotitis) is a viral infection caused by a paramyxovirus, primarily affecting the salivary glands, especially the parotid glands. The most characteristic and pathognomonic sign of mumps is bilateral parotid gland swelling, which sometimes starts on one side and then progresses to both sides.
The parotid glands are located in front of and below each ear, and when inflamed due to mumps, they become visibly swollen, giving the child a characteristic "chipmunk-like" appearance. This swelling is typically accompanied by significant pain and tenderness, especially when chewing or swallowing acidic foods or drinks. Ear pain occurs because the swollen parotid glands put pressure on surrounding structures, including the ear canal.
The swelling usually develops gradually over 1–2 days, peaks on day 3, and then gradually subsides over the following week. The child may also experience fever, headache, general malaise, and difficulty eating due to pain. Diagnosis of mumps is primarily clinical, based on the characteristic parotid swelling, other symptoms, and a history of potential exposure.
From a nursing perspective, assessment should include monitoring for complications such as orchitis in post-pubertal males, meningitis, and hearing loss. Nurses should also assess the child's hydration status, as difficulty swallowing can lead to decreased fluid intake. Since mumps is a viral infection that must run its course, pain management and supportive care are the main interventions.
Correct Answer: 4. Bilateral parotid gland swelling with earache
The most characteristic clinical presentation of mumps is acute, painful swelling of the salivary glands, most commonly the parotid glands. The mumps virus has a tropism for glandular tissue, and the inflammatory response within the parotid gland leads to the classic visible swelling at the angle of the jaw that may obscure the jawline and extend upward toward the ear. This swelling is frequently bilateral, though it may begin unilaterally and progress to the contralateral side over several days. The stretching of the parotid capsule, which is richly innervated, produces significant tenderness and pain that is often referred to the ear, resulting in the characteristic earache described in the correct option. Fever, malaise, and myalgia are common prodromal symptoms that precede the parotitis by 1 to 2 days, which aligns with the 2-day history of fever and facial swelling in the presented scenario [2].
The pathophysiology of this glandular swelling involves direct viral invasion of the parotid ductal epithelium, leading to local inflammation, edema, and obstruction of salivary flow. This mechanism explains the clinical finding of parotid tenderness that is exacerbated by tasting or chewing acidic or sour foods, a classic bedside assessment clue. While parotitis is the hallmark, mumps is a systemic infection that can involve other glandular tissues, including the pancreas, testes, and ovaries, as well as the central nervous system. A systematic review and meta-analysis of global mumps outbreaks confirmed that parotitis remains the predominant clinical feature, with complications such as orchitis and pancreatitis occurring at variable rates depending on age and vaccination status . In a vaccinated adolescent or young adult, as described in one case report, waning immunity can lead to a presentation where parotitis occurs concurrently with pancreatitis and orchitis, underscoring the virus's broad glandular tropism [2].
The other options represent pathognomonic findings for distinct viral exanthems that are critical to differentiate on the NCLEX-RN. Koplik's spots are small, white, salt-grain-like lesions on an erythematous buccal mucosa and are pathognomonic for measles (rubeola), not mumps. A fine, red, sandpaper-like rash on the trunk is the classic descriptor for the rash of scarlet fever, caused by group A beta-hemolytic Streptococcus pyogenes erythrogenic toxin. Vesicular lesions on the face and scalp are characteristic of varicella (chickenpox), where the rash appears in crops and progresses from macules to papules to vesicles and finally crusts, with a centripetal distribution. The mumps virus does not produce a rash; its clinical hallmark is the tender, swollen parotid gland. Frontline healthcare providers are advised to use a systematic "Identify-Isolate-Inform" approach when encountering a patient with acute parotitis and fever, as early recognition of this highly contagious viral infection is essential to prevent transmission, particularly in settings where vaccine-induced immunity may have waned, such as among adolescents and young adults in close-contact environments .

Mumps Assessment in ChildrenKey Clinical Findings for Parotitis
The hallmark of mumps is bilateral parotid gland swelling, often accompanied by earache due to stretching of the parotid capsule. Prodromal symptoms like fever and myalgia precede the swelling by 1-2 days.
Parotid tenderness is exacerbated by chewing or tasting acidic foods (e.g., lemon juice), a useful bedside assessment clue. Swelling obscures the angle of the jaw and may lift the earlobe.
