Pediatric Infectious Diseases PNLE Questions

Introduction

The live published inventory contains exactly 29 original PNLE-style practice questions; it was last updated August 12, 2026. This page uses those questions for diagnostic practice, not as actual, recalled, or leaked board questions. The set sits under NP2: Maternal & Child Health and covers childhood infections, recognition, isolation, treatment, and complications.

Practice decisions include identifying a likely infectious pattern, separating similar febrile rashes, choosing immediate infection-control actions, recognizing urgent findings, applying IMCI classification principles, supporting the acutely ill child, and escalating possible complications. The focus remains on infections rather than vaccination scheduling or noninfectious organ-system disorders.

This pedagogical lens is mapped across relevant competencies in the official five-subject PNLE TOS, including the 2025 Enhanced TOS. It is not a separate official test subject, and the TOS does not provide a guaranteed question count for this microtopic.

Key concepts

Recognize the infectious pattern before naming the disease
Recognize: Combine fever, rash or mucosal findings, respiratory symptoms, exposure clues, hydration, mental status, and the child's overall appearance. A single sign rarely provides enough information by itself.
Decide: Form a syndrome-based impression first, then select the safest assessment, isolation, referral, and treatment actions supported by the findings.
Avoid: Anchoring on one memorable sign while ignoring airway status, neurologic changes, intake, or the speed of deterioration.
Begin infection-control action from the suspected route
Recognize: Cough, respiratory secretions, vesicular or draining lesions, and a highly transmissible febrile illness can place other children and staff at risk before confirmation is available.
Decide: Apply the transmission-based precautions indicated by the suspected syndrome, limit exposure, use appropriate personal protective equipment, and follow facility policy for placement and notification.
Avoid: Waiting for a laboratory result before separating a potentially infectious child or transporting the child without communicating the risk.
Differentiate measles from varicella by the complete rash pattern
Recognize: Measles is associated with fever, cough, coryza, conjunctivitis, and Koplik spots, with a rash that classically begins on the face and spreads downward. Varicella commonly presents with pruritic vesicles appearing in crops, so lesions may be seen at different stages.
Decide: Inspect the mouth, eyes, respiratory symptoms, lesion distribution, and lesion stage together while initiating appropriate precautions.
Avoid: Calling every fever with a rash measles or using itch alone as the deciding feature.
Treat stiff neck or IMCI danger signs as urgent findings
Recognize: Fever with nuchal rigidity, altered responsiveness, inability to drink, breathing difficulty, or two or more pink signs indicates a child who needs prompt chart-based classification and escalation.
Decide: Use the IMCI chart, prioritize airway and breathing, notify the appropriate clinician, and prepare for urgent referral or treatment according to the classification.
Avoid: Delaying action for a complete history, reassuring yourself because the fever is not very high, or downgrading risk because one assessment finding appears normal.
Support the acutely ill child while carrying out prescribed treatment
Recognize: Infection can increase work of breathing, fluid losses, fatigue, discomfort, and poor intake. Diphtheria care may require special attention to airway safety and reduced exertion.
Decide: Verify the prescription, allergy status, route, and weight-related safety checks; provide ordered therapy, hydration support, comfort measures, rest, clustered care, and repeated reassessment.
Avoid: Treating fever alone as proof that an antibiotic is needed, giving unverified medication advice, or exhausting the child with unnecessary handling.
Screen continuously for complications
Recognize: Worsening breathing, cyanosis, reduced intake, altered mental status, seizures, new cardiac or neurologic changes, or severe weakness can signal deterioration. A male child with mumps who develops testicular pain or swelling requires prompt assessment for orchitis.
Decide: Compare findings over time, document changes, escalate promptly, and maintain safety precautions while the child receives further evaluation.
Avoid: Assuming that a known diagnosis guarantees a mild course or stopping surveillance when the temperature improves.

What to expect on the PNLE

The inventory supports several question forms: identifying classic manifestations, differentiating measles from varicella, selecting care for a febrile or acutely ill child, choosing isolation actions, applying IMCI classification, and recognizing complications such as those associated with mumps or diphtheria. These forms require more than naming a disease because the learner must connect clinical cues to a safe nursing action.

Within the 29-question inventory, the difficulty distribution is 9 easy, 15 medium, and 5 hard. The Bloom distribution is 8 remembering, 13 applying, 3 analyzing, and 5 evaluating, so practice should include recall of hallmark findings plus prioritization, comparison, interpretation of danger signs, and judgment about escalation. Exact topic distribution varies by exam form; these inventory proportions are not a prediction of a particular examination.

Remembering: retrieve classic signs, complications, and basic care principles.
Applying: use findings to select precautions, supportive care, or the next nursing action.
Analyzing: compare overlapping febrile illnesses and interpret combinations of findings.
Evaluating: rank urgency, judge deterioration, and decide when referral or escalation is required.

Study tips

Start with a diagnostic pass. Answer a small mixed set from Pediatric Infectious Diseases without reviewing notes first. Label each error as recognition, isolation, treatment, complication, or IMCI classification so the next study block targets a decision rather than a vague disease list.
Build a comparison grid for focused retrieval. Recreate this from memory, then correct it using your rationales:
Comparison grid:
Feature | Measles | Varicella
Respiratory or mucosal clues | cough, coryza, conjunctivitis, Koplik spots | vesicular eruption and pruritus
Rash pattern | classically face first, then downward spread | crops with lesions at different stages
Immediate nursing focus | precautions, airway, hydration, complications | precautions, skin care, hydration, complications
Review the rationale and your error path. For every missed item, write the decisive cue, the unsafe alternative, and the action that protects the child or contacts. Include why a stiff neck, pink signs, or airway change changes urgency.
Retry with spacing. Reanswer missed questions after a delay, then again during a later session. Retrieve IMCI classification steps, measles and varicella distinctions, diphtheria safety actions, and mumps complications without looking at the answer first.
Finish with mixed timed practice. Combine infection questions with adjacent pediatric respiratory or immunization items only after the infection decisions are stable. Review timing errors separately from knowledge errors, and do not convert the 29-question inventory into a predicted exam quota.

Common mistakes to avoid

Choosing a disease from fever alone. Fever is a nonspecific cue. Correct the reasoning by checking the full pattern: respiratory and mucosal findings, lesion stage and distribution, exposure risk, hydration, mental status, and progression.
Waiting for confirmation before using precautions. A child may transmit infection while testing is pending. The safety principle is to act on the suspected route, limit contact, use appropriate PPE, and communicate the concern according to facility policy.
Missing the urgency of nuchal rigidity or pink signs. Stiff neck with fever and two or more pink signs should trigger chart-based IMCI classification and prompt escalation. Do not let a normal appetite, a modest temperature, or one reassuring observation cancel a danger sign.
Prioritizing the label over ABC and hydration. Knowing the infection does not replace assessment of breathing, circulation, intake, urine output, responsiveness, and fatigue. Reassess after interventions because a child can worsen quickly.
Giving treatment that is not supported by the order or assessment. Fever does not automatically establish a need for antibiotics, and medication safety requires verification of the prescription, allergy status, route, and weight-related checks. Use supportive care and prescribed therapy while escalating findings that suggest complications.
Forgetting disease-specific complications. A male child with mumps needs assessment for testicular pain or swelling, while diphtheria requires vigilance for airway, cardiac, and neurologic deterioration. Link each complication to a monitoring cue and a prompt escalation action.

Medium

Five days after mumps begins, a 17-year-old develops unilateral testicular pain, swelling, and low-grade fever. Which complication should the nurse suspect?

A

Epididymal torsion

B

Viral meningitis

C

Pancreatitis

D

Orchitis

Rationale

A 17-year-old with a recent mumps infection who now presents with unilateral testicular pain, swelling, and low-grade fever is most likely experiencing mumps orchitis. This is a well-recognized complication of mumps, especially in post-pubertal males.

Why This Is Correct (D: Orchitis): Mumps is caused by a paramyxovirus and most commonly presents with parotitis (swelling of the parotid glands). However, after initial infection, the virus can spread hematogenously to other tissues, most notably the testes in post-pubertal males. Orchitis typically occurs about 4-8 days after onset of parotitis and is characterized by unilateral or bilateral testicular pain, tenderness, swelling, erythema, and sometimes fever. Recognizing this progression is key for nursing care, as orchitis can lead to long-term complications, including infertility. The standard of care includes supportive management: bed rest, scrotal elevation, pain control, and fever management. Early recognition helps prevent unnecessary testing and focuses care.

Why the Other Answers Are Incorrect:

Option	Explanation
A. Epididymal torsion	Testicular torsion is an emergency presenting with sudden, severe scrotal pain and swelling, often with nause/vomiting but not generally with fever. It is not a complication of mumps infection. Key clinical pearl: A history of recent mumps strongly suggests orchitis, not torsion.
B. Viral meningitis	Mumps virus can lead to aseptic meningitis, but the symptoms are headache, neck stiffness, photophobia, and altered mental status, not isolated testicular pain and swelling.
C. Pancreatitis	Mumps can involve the pancreas, presenting with abdominal pain and vomiting, but would not cause isolated testicular symptoms. Pancreatitis would be suspected in a patient with epigastric pain rather than scrotal pain.

Nursing Concepts and Clinical Reasoning:

Testicular/scrotal pain in adolescents or young men always requires prompt evaluation to rule out emergent causes (torsion), but the presence of constitutional symptoms and viral prodrome points toward an infectious etiology here.
The nurse should use knowledge of mumps pathophysiology and typical disease course to guide differential diagnosis, prompt appropriate supportive management, and provide education about potential fertility risks if orchitis is present.

Clinical Pearls:

Classic association: "Mumps means lumps"—often mnemonic reminder for parotitis and testicular swelling.
Differentiate painful, gradual-onset swelling after mumps (orchitis) from sudden-onset, severe pain in torsion (surgical emergency).

Early identification and patient/family teaching about mumps sequencing and potential complications are fundamental nursing responsibilities, supporting safe, evidence-based care.
