What is the most common bacterial cause of community-acquired pneumonia in adults?
Mycoplasma pneumoniae
Haemophilus influenzae
Staphylococcus aureus
Streptococcus pneumoniae
Streptococcus pneumoniae is the leading cause of community-acquired pneumonia in adults due to its ability to colonize the upper respiratory tract and evade host defenses. It often presents with abrupt onset of fever, productive cough, and pleuritic chest pain. Prompt recognition and targeted antibiotic therapy reduce complications and mortality. CDC
Which symptom is most characteristic of pneumonia?
Bilateral leg swelling
Productive cough with purulent sputum
Chronic headache
Sharp abdominal pain
Pneumonia typically presents with a productive cough and purulent or rust-colored sputum due to infection and inflammation in the alveoli. Other associated features include fever, dyspnea, and chest pain. Recognizing the productive cough helps distinguish pneumonia from other respiratory conditions. NCBI
On auscultation, which finding is most suggestive of consolidation in pneumonia?
Wheezing
Bronchial breath sounds
Stridor
Vesicular breath sounds
Bronchial breath sounds over peripheral lung fields indicate consolidation, as sound transmission is enhanced through fluid-filled alveoli. Normal vesicular sounds are softer and not suggestive of consolidation. Identifying bronchial sounds guides further diagnostic evaluation. PMC
Which radiographic finding is most consistent with lobar pneumonia?
Pleural effusion only
Diffuse interstitial infiltrates
Homogeneous consolidation of a single lobe
Cavitation in the apex
Lobar pneumonia typically appears as homogeneous consolidation confined to one or more lobes of the lung on chest x-ray. Diffuse interstitial patterns suggest atypical or viral pneumonia. Recognizing lobar consolidation helps narrow down the likely pathogens and management. Radiopaedia
Which vital sign combination is most indicative of sepsis in a pneumonia patient?
Temperature <36°C, bradycardia, respiratory rate <12/min
Temperature >38°C, heart rate >90/min, respiratory rate >20/min
Elevated blood pressure, bradypnea, hypothermia
Normal temperature, heart rate 60/min, respiratory rate 16/min
Sepsis criteria include systemic inflammatory response syndrome (SIRS) with temperature >38°C, heart rate >90/min, respiratory rate >20/min, and altered white blood cell count. Early recognition of these signs in pneumonia can prompt timely sepsis management. SCCM
Which laboratory finding is commonly elevated in bacterial pneumonia?
Serum albumin
White blood cell count
Serum potassium
Blood glucose
Bacterial pneumonia often triggers a leukocytosis as the immune system responds to infection. An elevated white blood cell count, particularly with a left shift, supports the diagnosis. Other lab values are less specific for pneumonia. NCBI
Which of the following is the primary route of pneumonia infection?
Ingestion of contaminated food
Blood transfusion
Inhalation of respiratory droplets
Direct skin contact
Pneumonia pathogens are most often transmitted via inhalation of aerosolized respiratory droplets from an infected person. This mode allows bacteria or viruses to reach the alveoli. Direct skin contact and ingestion do not lead to pulmonary colonization. CDC
What is the recommended first-line outpatient antibiotic for uncomplicated community-acquired pneumonia in a healthy adult?
Ciprofloxacin
Daptomycin
Azithromycin
Vancomycin
Azithromycin is recommended as first-line therapy for outpatient treatment of healthy adults with community-acquired pneumonia due to its activity against common pathogens and convenient dosing. Vancomycin and daptomycin are reserved for resistant Gram-positive infections. IDSA
Which nursing intervention helps prevent hospital-acquired pneumonia?
Frequent oral hygiene and head-of-bed elevation
Limiting fluid intake strictly
Keeping the patient supine at all times
Avoiding incentive spirometry
Oral hygiene reduces oropharyngeal colonization by pathogens, and elevating the head of the bed decreases aspiration risk. Incentive spirometry also aids lung expansion. Supine positioning and restricted fluids do not prevent pneumonia. AHRQ
Which patient position best improves oxygenation in pneumonia?
Prone with head down
Semi-Fowler's position
Full supine
Trendelenburg position
Semi-Fowler's position (head elevated 30 - 45 degrees) optimizes diaphragmatic movement and reduces pressure on the lungs, improving ventilation and oxygenation. Trendelenburg and full supine positions can compromise respiratory mechanics. PMC
Which score is used to assess severity and guide hospitalization decisions in community-acquired pneumonia?
CURB-65
SOFA
APGAR
Glasgow Coma Scale
The CURB-65 score (confusion, urea >7 mmol/L, respiratory rate ?30, blood pressure low, age ?65) is validated to assess pneumonia severity and decide on inpatient versus outpatient care. Scores ?2 often indicate hospitalization. Other scores assess different conditions. PMC
What is the principal driver for starting empiric broad-spectrum antibiotics in a patient with suspected hospital-acquired pneumonia?
Cost containment
Time to effective therapy to reduce mortality
Avoiding blood cultures
Minimizing nursing care
Early, appropriate empiric broad-spectrum antibiotic therapy in hospital-acquired pneumonia is critical to reduce mortality. Delays in effective treatment are linked to poorer outcomes. Therapy is later narrowed based on culture results. IDSA
Which pathogen is most commonly associated with hospital-acquired pneumonia?
Mycoplasma pneumoniae
Chlamydophila pneumoniae
Pseudomonas aeruginosa
Legionella pneumophila
Pseudomonas aeruginosa is a frequent cause of hospital-acquired pneumonia due to its environmental persistence and antibiotic resistance. It often affects patients on ventilators or those with prolonged hospital stays. Community atypical pathogens are less common in HAP. CDC
Which laboratory marker can help distinguish bacterial pneumonia from viral pneumonia?
Serum calcium
Procalcitonin
Blood urea nitrogen
Serum sodium
Procalcitonin levels rise in bacterial infections and remain low in viral illnesses, making it useful to guide antibiotic stewardship in pneumonia. Elevated procalcitonin suggests bacterial etiology. Other markers are nonspecific. PMC
Which type of pneumonia is most common in immunocompromised patients?
Mycoplasma pneumonia
Legionella pneumonia
Klebsiella pneumonia
Pneumocystis jirovecii pneumonia
Pneumocystis jirovecii pneumonia frequently affects patients with HIV/AIDS or those on immunosuppressants, causing diffuse interstitial infiltrates. Early prophylaxis and treatment are vital to reduce morbidity. Other bacteria also infect but less specifically immunocompromised hosts. CDC
A patient presents with pneumonia and hyponatremia. Which organism should you suspect?
Legionella pneumophila
Staphylococcus aureus
Streptococcus pyogenes
Haemophilus influenzae
Legionella pneumophila often causes hyponatremia due to its effect on antidiuretic hormone release and renal salt handling. It also presents with high fever and gastrointestinal symptoms. Recognizing hyponatremia can prompt Legionella testing. CDC
Which antimicrobial regimen is recommended for ventilator-associated pneumonia with risk factors for multi-drug resistance?
Azithromycin alone
Amoxicillin alone
Anti-pseudomonal beta-lactam plus aminoglycoside
Vancomycin monotherapy
In VAP with MDR risk factors, combination therapy with an anti-pseudomonal beta-lactam and an aminoglycoside or fluoroquinolone covers resistant Gram-negative organisms. Monotherapy with narrow-spectrum agents is inadequate. IDSA
Which clinical feature best differentiates atypical pneumonia from typical bacterial pneumonia?
Rust-colored sputum
High neutrophil count
Dry, nonproductive cough
Severe pleuritic chest pain
Atypical pneumonia, caused by organisms like Mycoplasma or Chlamydophila, often presents with a dry, nonproductive cough and milder systemic symptoms. Typical bacterial pneumonia usually has productive sputum and more abrupt onset. Differentiation guides antibiotic choice. NCBI
What is the recommended duration of antibiotic therapy for uncomplicated community-acquired pneumonia in adults?
30 days
1 - 2 days
14 - 21 days
5 - 7 days
Current guidelines recommend a minimum of 5 days of antibiotic therapy for uncomplicated community-acquired pneumonia in adults, with at least 48 - 72 hours afebrile and no more than one sign of clinical instability before stopping. Longer courses increase resistance risk. IDSA
Which diagnostic test is most sensitive for detecting lung consolidation in early pneumonia?
Chest CT scan
Standard chest X-ray
Pulse oximetry
Sputum Gram stain
Chest CT is more sensitive than plain radiography in identifying early or subtle lung consolidation and ground-glass opacities. It can detect minor infiltrates that X-ray may miss, guiding diagnosis in complex cases. Gram stain and pulse oximetry do not visualize consolidation. AJR
In aspiration pneumonia, which lung region is most commonly affected in a supine patient?
Right upper lobe apex
Bilateral apices
Left lingular segment
Superior segment of the right lower lobe
In supine patients, aspirated material often gravitates to the superior segment of the right lower lobe due to anatomical orientation of the bronchi. Recognizing this helps target imaging and management. Upright patients more commonly aspirate to the basal segments. NCBI
Which inflammatory mediator is most associated with increased vascular permeability in pneumonia?
Thrombopoietin
Interleukin-1 (IL-1)
Erythropoietin
Insulin
IL-1 is a proinflammatory cytokine that increases vascular permeability, leading to alveolar exudate and consolidation seen in pneumonia. It also stimulates fever and leukocyte recruitment. Other listed hormones do not mediate this inflammatory response. PMC
Which finding best predicts poor prognosis in elderly pneumonia patients?
Hypoxia (PaO? <60 mm Hg)
Mild cough
White nails
Low heart rate
Hypoxia with PaO? <60 mm Hg indicates severe pulmonary impairment and correlates with increased mortality in pneumonia, especially in elderly patients. This finding guides escalation of care, including ICU admission. Mild cough and nail changes are not prognostic. NEJM
In pediatric pneumonia, which pathogen is most common in children under 5 years old?
Mycoplasma pneumoniae
Respiratory syncytial virus
Legionella pneumophila
Chlamydophila pneumoniae
RSV is the leading viral cause of pneumonia in children under 5, often resulting in bronchiolitis and lower respiratory tract infection in infants. Mycoplasma and other atypical pathogens are more common in older children and adolescents. CDC
Which ventilator setting adjustment can help manage acute respiratory distress syndrome secondary to pneumonia?
High tidal volume (12 mL/kg)
Permissive hyperoxia
Low tidal volume ventilation (6 mL/kg)
Zero positive end-expiratory pressure
Low tidal volume ventilation (about 6 mL/kg of predicted body weight) reduces ventilator-induced lung injury in ARDS by preventing overdistension of alveoli. Higher volumes increase barotrauma, and zero PEEP worsens alveolar collapse. Permissive hypercapnia - not hyperoxia - is sometimes used. NEJM
Which scoring system specifically predicts mortality in ventilator-associated pneumonia?
Wells score
CPIS (Clinical Pulmonary Infection Score)
FRAX
APACHE II
The Clinical Pulmonary Infection Score (CPIS) includes temperature, leukocyte count, oxygenation, radiographic findings, tracheal secretions, and culture results to assess VAP severity and predict mortality. APACHE II is more general for ICU patients. PMC
Which pathogen is most often implicated in post-influenza pneumonia?
Legionella pneumophila
Mycoplasma pneumoniae
Haemophilus influenzae
Staphylococcus aureus
Post-influenza pneumonia frequently results from secondary infection with Staphylococcus aureus due to damaged respiratory epithelium and immune dysregulation. This typically presents with rapid clinical decline after initial viral illness. CDC
Which complication is most likely in patients with necrotizing pneumonia?
Deep vein thrombosis
Acute pancreatitis
Pulmonary abscess formation
Acute appendicitis
Necrotizing pneumonia leads to tissue liquefaction and cavitation, resulting in abscess formation within lung parenchyma. This can prolong treatment and require drainage. Thrombosis and abdominal complications are unrelated. NCBI
Which molecular test rapidly identifies multiple respiratory pathogens in pneumonia from a single specimen?
Rapid antigen test for influenza only
Single blood culture
Multiplex PCR panel
Traditional sputum culture
Multiplex PCR panels detect a range of viral and bacterial pathogens from respiratory specimens within hours, guiding targeted therapy. Traditional cultures take days and antigen tests are limited to single pathogens. PMC
In severe community-acquired pneumonia with shock, which adjunctive therapy may improve outcomes?
Oral zinc supplements
Routine hyperbaric oxygen
High-dose vitamin C
Corticosteroids
Adjunctive corticosteroids in severe community-acquired pneumonia have been shown to reduce inflammatory response, time to clinical stability, and mortality in patients with shock or high inflammatory markers. Other therapies lack robust evidence. NEJM
Which radiographic sign on CT suggests necrotizing pneumonia rather than simple consolidation?
Multiple areas of low attenuation within consolidation
Isolated pulmonary nodule
Uniform ground-glass opacity
Interstitial thickening only
Low-attenuation areas indicate necrosis and liquefaction within consolidated lung tissue, characteristic of necrotizing pneumonia. Uniform ground-glass opacities suggest nonnecrotic processes. Identifying necrosis influences management. Radiology Assistant
Which immune cell predominates in pneumonia caused by Pneumocystis jirovecii?
Basophils in alveoli
Eosinophils in airways
Alveolar macrophages laden with cysts
Neutrophils with phagosomes
Pneumocystis jirovecii infection features organisms within alveolar macrophages and a foamy exudate in alveoli. Neutrophils are less prominent, and eosinophils or basophils are not characteristic of this fungal pneumonia. NCBI

Cheat Sheet

  1. Classification of Pneumonia -

    Review the three main types - community-acquired (CAP), hospital-acquired (HAP), and ventilator-associated pneumonia (VAP) - by their onset and risk factors, as outlined by IDSA/ATS guidelines. Remember that CAP presents within 48 hours of admission, while HAP/VAP occur after 48 hours and carry higher MDR organism risks. Solidly nailing these distinctions will boost your performance on any nursing pneumonia quiz.

  2. Key Pathogens Mnemonic "MRS HEN" -

    Memorize common bacterial culprits with "MRS HEN": Mycoplasma, RSV/Viral, Strep pneumoniae, Haemophilus influenzae, Enterobacteriaceae, and Neisseria. This friendly rhyme helps you recall etiology during Pneumonia management questions or chart reviews. Bonus tip: link each letter to a patient scenario to make it stick.

  3. CURB-65 Severity Scoring -

    Use the CURB-65 mnemonic (Confusion, Urea >7 mmol/L, Respiratory rate ≥30, Blood pressure low, Age ≥65) to stratify CAP severity and determine inpatient vs. outpatient care. Each positive criterion scores one point - total ≥2 suggests hospital admission per NICE/IDSA. Practicing sample cases will reinforce how you apply this tool under pressure.

  4. Interpreting ABGs & A-a Gradient -

    Calculate the alveolar-arterial (A-a) gradient: PAO₂ = [FiO₂ x (Patm - PH₂O)] - (PaCO₂ /0.8), then subtract measured PaO₂; an elevated gradient (>15 mmHg) indicates impaired gas exchange. This formula is a must-know for respiratory nursing quiz questions on hypoxemia. Try one or two mock ABG arrays weekly to stay sharp.

  5. Nursing Interventions & Patient Education -

    Implement incentive spirometry, chest physiotherapy, and 45° Fowler's positioning to enhance lung expansion and secretion clearance. Encourage adequate hydration and explain antibiotic regimen adherence - teaching points that often feature in pneumonia nursing trivia. Framing interventions as "your path to faster recovery" keeps patients motivated and demonstrates your best-care practices.
