Infectious Diseases PNLE Questions
Introduction
The live published inventory contains exactly 25 original PNLE-style practice questions for Infectious Diseases. The inventory was last updated August 12, 2026, and should be used as a focused practice set rather than as a forecast of any exam form.
The canonical scope covers clinical nursing care for systemic, bacterial, viral, fungal, parasitic, and opportunistic infections. Practice decisions include recognizing disease patterns, identifying deterioration, selecting an appropriate assessment or diagnostic action, obtaining a useful specimen, explaining manifestations, and prioritizing care for serious complications.
Infectious Diseases belongs to NP4, Medical-Surgical, as a Tangerine practice area. It is a pedagogical lens mapped across relevant competencies in the official five-subject PNLE TOS, not a separate official test subject. The 2025 Enhanced TOS provides weights for broad competency areas, so it does not establish a guaranteed microtopic weight or a fixed number of Infectious Diseases questions on any exam form.
Key concepts
- Recognize systemic deterioration
Recognize: Infection may affect several systems, so worsening mental status, breathing, circulation, temperature-related changes, or urine output can matter more than the original local complaint.
Decide: Assess airway, breathing, circulation, level of consciousness, and trends, then escalate urgent findings according to the clinical setting.
Avoid: Focusing on the suspected organism or one laboratory result while overlooking an unstable patient. - Match the clinical pattern to the infection category
Recognize: The useful pattern combines site, time course, associated findings, exposures, and host factors. Systemic bacterial, viral, fungal, parasitic, and opportunistic infections may require different nursing priorities.
Decide: Link the cluster of findings to the most relevant disease process before selecting the assessment, specimen, or immediate intervention.
Avoid: Naming an infection from one nonspecific symptom or assuming that every fever represents the same process. - Evaluate suspected pulmonary tuberculosis and specimen quality
Recognize: A persistent respiratory symptom pattern with compatible constitutional findings or relevant risk cues warrants a tuberculosis evaluation; the quality of the respiratory specimen affects the usefulness of testing.
Decide: Follow the ordered diagnostic pathway, explain the collection procedure, obtain a properly identified sputum specimen rather than saliva, and follow instructions for handling and transport.
Avoid: Ruling out tuberculosis because one expected symptom is absent, or accepting an inadequate specimen without addressing the problem. - Prioritize complications of malaria
Recognize: Recurrent febrile illness may occur with anemia, jaundice, weakness, altered consciousness, breathing difficulty, circulatory compromise, or significant urine changes.
Decide: Assess neurologic status, respiratory effort, circulation, hydration, urine output, and the trend of anemia or jaundice; report signs of severe deterioration promptly.
Avoid: Treating anemia or jaundice as a routine finding when the patient also has neurologic, respiratory, or hemodynamic changes. - Identify generalized tetanus as an airway and safety emergency
Recognize: Trismus, dysphagia, generalized rigidity, painful spasms, and possible laryngeal or respiratory involvement indicate increasing risk.
Decide: Prioritize airway and breathing assessment, reduce avoidable stimulation, maintain safety, and obtain urgent assistance when spasms or respiratory compromise develop.
Avoid: Describing severe rigidity as an ordinary muscle complaint or waiting for a later sign before escalating care. - Interpret skin, fungal, parasitic, and opportunistic findings in context
Recognize: Pruritus, lesions, mucosal changes, recurrent infection, or an unusual presentation must be considered with distribution, exposure, immune status, nutrition, and other findings.
Decide: Inspect systematically, assess discomfort and functional effects, identify host vulnerabilities, and report findings that suggest a more extensive or opportunistic process.
Avoid: Labeling every itchy rash as scabies or every lesion as fungal without considering the full pattern and the patient’s defenses.
What to expect on the PNLE
The live inventory supports several question forms: recognizing a symptom pattern that warrants evaluation, selecting an initial diagnostic action, choosing the correct specimen-collection approach, identifying a key assessment finding, recognizing a serious complication, and explaining how an infection produces a manifestation. These forms require the learner to connect findings with a nursing decision rather than recall an organism name in isolation.
Its difficulty distribution is easy=13, medium=9, and hard=3. Its Bloom distribution is remembering=10, applying=9, analyzing=4, and evaluating=2. Prepare for direct retrieval of defining findings, application of a safety priority to a patient presentation, analysis of related cues, and evaluation of competing actions; these are the cognitive demands represented in this practice inventory.
- Pattern prompts: group symptoms and risk cues before deciding what needs evaluation.
- Testing and specimen prompts: identify the requested step and check specimen quality, procedure, and sequence.
- Complication prompts: prioritize the finding that signals airway, breathing, neurologic, circulatory, or systemic danger.
- Explanation prompts: connect the disease process with the observed manifestation and the resulting nursing priority.
The exact topic distribution varies by exam form. The inventory can guide balanced practice across the canonical scope, but it cannot establish a fixed number of questions for tuberculosis, malaria, tetanus, or any other microtopic.
Study tips
- Start with diagnostic practice. Answer all 25 inventory questions before reviewing rationales. Record your answer, confidence level, and the exact cue that drove your choice; a correct answer based on guessing belongs in the review list.
- Use focused retrieval for patterns. Cover your notes and recall the priority cues for tuberculosis, malaria, tetanus, systemic infection, and skin, fungal, parasitic, or opportunistic presentations. Make a comparison table: create columns for infection or syndrome, defining pattern, immediate nursing priority, specimen or test action, and danger sign; add one concise row for each scope group.
- Review the rationale and the error. For every missed or guessed item, write the cue you missed, the unsafe alternative you considered, and the decision rule that corrects it. Separate knowledge gaps from errors in prioritization, specimen collection, or interpretation of complications.
- Schedule a spaced retry. Return to the error list in later study sessions without looking at the previous answer. Explain why the correct action fits the clinical pattern and why the strongest distractor is less safe.
- Finish with mixed timed practice. Combine recognition, application, analysis, and evaluation prompts, then review reasoning after the timed set. Mix infection presentations and adjacent clinical topics so you must identify the relevant decision rather than rely on the order of your notes.
Common mistakes to avoid
- Anchoring on one symptom: Learners may select an infection from fever, cough, rash, or pain alone. Correct the error by weighing the whole pattern, including time course, associated findings, exposures, and host factors.
- Missing deterioration in malaria: Anemia or jaundice may draw attention away from altered consciousness, breathing difficulty, circulatory compromise, or changing urine output. The safety cue is the combination of the manifestation with evidence of organ or systemic involvement, which requires prompt escalation.
- Choosing a test without considering the specimen: A tuberculosis question may be answered with a test name while ignoring whether the collected material is an adequate respiratory specimen. First identify the requested diagnostic step, then apply correct patient identification, collection, and handling principles.
- Underestimating tetanus manifestations: Trismus, dysphagia, rigidity, and spasms can be mislabeled as discomfort or anxiety. The correcting principle is to treat progressive spasms and any airway or breathing change as urgent clinical deterioration.
- Overdiagnosing a skin infection from appearance alone: An itchy lesion is not enough to label scabies or fungal disease, and an unusual lesion in a patient with impaired defenses may signal a broader problem. Compare distribution, symptoms, immune status, and associated findings before deciding.
- Answering an adjacent concept instead of the asked decision: If the stem asks for a complication, initial assessment, diagnostic action, or specimen procedure, do not substitute a general infection-control response. Keep the primary cue and the requested nursing decision aligned.

A client with infective endocarditis develops flank pain and hematuria. Which complication best explains this?
Clients with infective endocarditis are at significant risk of developing embolic complications, as vegetations (clusters of bacteria and cellular debris) on the heart valves can break off and travel through the bloodstream. When these emboli lodge in the renal (kidney) circulation, they can cause infarction (tissue death due to lack of blood supply). This process results in symptoms such as acute flank pain (pain on one side of the back or abdomen) and hematuria (blood in the urine), which are classic findings in renal infarction secondary to septic emboli.
<!-- rationale-image:1102 -->
The clinical reasoning relies on recognizing the pathophysiology of embolic phenomena: infective endocarditis can cause fragments to dislodge from infected heart valves, seeding distant organs, especially highly vascular organs like the kidneys. Renal infarction leads to local tissue hypoxia, necrosis, and release of blood into the urinary tract, resulting in both pain and visible hematuria. This is a high-yield concept emphasized in Med-Surg board review texts as a serious and potentially life-threatening complication.
Let's analyze each option:
| Option | Analysis |
|---|---|
| A | Primary nephrotic syndrome primarily presents with massive proteinuria, severe edema, hypoalbuminemia, and hyperlipidemia. While hematuria and flank pain can rarely occur, these are not hallmark symptoms and nephrotic syndrome is not a typical acute complication of infective endocarditis. |
| B | Urethral obstruction (such as from a stone or stricture) can impair urine flow and may cause pain and hematuria, but it is not a direct or expected complication of infective endocarditis. The question specifically asks for a complication best explained by the client's endocarditis. |
| C | Reduced aldosterone secretion would lead to sodium loss, fluid depletion, and hypotension, but these do not cause flank pain or hematuria and are not related as primary complications of infective endocarditis. |
| D | Septic embolization to the kidney is a classic and well-documented complication of infective endocarditis. It presents acutely with flank pain due to ischemia and hematuria from infarction and tissue necrosis. This option directly connects the client’s infection to their new urinary and pain symptoms, demonstrating both clinical knowledge and sound reasoning. |
Clinical Pearl: Always consider embolic complications (brain, lungs, spleen, kidney) in clients with infective endocarditis who develop sudden symptoms in other organs. This framework is promoted in Udan’s comprehensive Med-Surg review and is a board-level pattern nursing students must master.
