The central decision in community-acquired pneumonia is where the patient is treated, and CURB-65 turns that into 5 scoreable findings. These questions cover severity assessment, which patients can safely be managed at home, empiric antibiotic selection including for comorbidities, when imaging is needed, and the follow-up interval that catches deterioration. All 10 are drawn from the content areas the Family Nurse Practitioner boards actually test.
Question 1
A 65-year-old patient with advanced Alzheimer's disease develops aspiration pneumonia and lacks decision-making capacity. The patient has no written advance directives. The patient's estranged spouse and two adult children disagree on initiating artificial nutrition. Who has the legal authority to make this decision?
- A) The adult children by majority consensus.
- B) The facility ethics committee via consultation.
- C) The primary care provider managing treatment.
- D) The legally married but estranged spouse.✓
💡 Key Takeaway
The legal spouse is the primary default surrogate decision-maker when no healthcare proxy exists.
Show rationale
In the absence of a designated healthcare proxy, state laws dictate a surrogate hierarchy for medical decisions. The legal spouse is universally recognized as the primary default surrogate, regardless of estrangement, unless legally separated or divorced. The adult children are secondary in the hierarchy and cannot override the spouse. The primary care provider and ethics committee provide clinical guidance and conflict resolution but do not hold primary legal decision-making authority over an available spouse.
Question 2
A 45-year-old male presents with severe dyspnea and hemoptysis five days after testing positive for influenza A. His chest X-ray reveals multilobar infiltrates with a distinct cavitary lesion in the right lower lobe. Which interpretation is most strongly associated with these specific radiographic findings?
- A) Atypical pneumonia caused by Mycoplasma pneumoniae.
- B) Necrotizing pneumonia caused by Staphylococcus aureus.✓
- C) Typical pneumonia caused by Streptococcus pneumoniae.
- D) Lobar pneumonia caused by Haemophilus influenzae.
💡 Key Takeaway
Post-influenza pneumonia with cavitary lesions strongly suggests severe necrotizing infection by Staphylococcus aureus.
Show rationale
The presence of a cavitary lesion combined with a recent influenza infection is highly suspicious for necrotizing pneumonia caused by Staphylococcus aureus, particularly methicillin-resistant strains. While Streptococcus pneumoniae is the most common cause of community-acquired pneumonia overall, it typically presents as a focal lobar consolidation without cavitation. Mycoplasma pneumoniae usually manifests as diffuse interstitial infiltrates rather than destructive cavitary lesions. Haemophilus influenzae can cause lobar pneumonia, especially in patients with chronic obstructive pulmonary disease, but it rarely causes rapid, severe necrotizing disease post-influenza. Recognizing this specific radiographic pattern is critical because it requires aggressive antibiotic therapy targeting staphylococcal pathogens rather than standard first-line empiric regimens.
Question 3
A 55-year-old male returns for follow-up 14 days after completing therapy for community-acquired pneumonia. He reports complete resolution of symptoms and his physical examination is unremarkable. He asks if he needs another chest x-ray. What is the best response?
- A) Schedule a repeat chest radiograph today to ensure clearance.
- B) Order a repeat chest radiograph in exactly four weeks.
- C) Advise that routine follow-up imaging is not clinically indicated.✓
- D) Recommend a low-dose computed tomography scan for screening.
💡 Key Takeaway
Routine follow-up chest radiographs are unnecessary for patients with complete clinical resolution of community-acquired pneumonia.
Show rationale
For patients whose symptoms have completely resolved after completing therapy, routine follow-up imaging is not recommended due to unnecessary radiation and healthcare costs. Radiographic clearance often lags significantly behind clinical resolution. Option A is incorrect because early imaging may still show residual infiltrates despite a clinical cure. Option B is incorrect unless the patient has persistent symptoms or a high risk for malignancy. Option D is incorrect as it is not the standard follow-up for resolved infections.
Question 4
An 82-year-old patient with advanced Alzheimer's disease is evaluated after a third hospitalization for recurrent aspiration pneumonia in the past six months. The patient is nonverbal, incontinent, and unable to sit up independently, consistent with FAST stage 7C. Which intervention is most appropriate?
- A) Initiate an immediate referral for home hospice services.✓
- B) Order a swallowing evaluation for safe diet modification.
- C) Prescribe a daily prophylactic oral antibiotic treatment regimen.
- D) Consult palliative care to continue active medical treatment.
💡 Key Takeaway
Advanced dementia with recurrent infections and severe functional decline meets criteria for hospice referral.
Show rationale
This patient demonstrates severe functional decline and recurrent life-threatening infections, meeting the criteria for hospice care under the Medicare guidelines for advanced dementia. A FAST score of 7C combined with recurrent infections indicates a prognosis of less than six months, making hospice the most appropriate referral to prioritize comfort. Option B is suboptimal because diet modifications rarely prevent aspiration in this late stage of dementia. Option C is incorrect as prophylactic antibiotics do not improve survival or comfort in end-stage dementia and promote resistance. Option D delays the necessary transition to hospice, which is specifically designed for end-of-life care when active treatment is no longer beneficial.
Question 5
A 60-year-old male with severe COPD is currently taking a daily LAMA and LABA. He had three exacerbations last year and recently recovered from his second episode of community-acquired pneumonia in 14 months. His eosinophil count is 150 cells/mcL.
- A) Add a daily inhaled corticosteroid to the regimen.
- B) Discontinue the LAMA and start an inhaled steroid.
- C) Maintain current inhalers and add daily oral roflumilast.✓
- D) Maintain current inhalers and add daily oral prednisone.
💡 Key Takeaway
Recurrent pneumonia is a strong contraindication for adding inhaled corticosteroids in severe COPD management.
Show rationale
This patient has frequent exacerbations, placing him in GOLD Group E. While his eosinophil count might normally prompt consideration of an inhaled steroid, his history of recurrent pneumonia is a strong contraindication. Option C is the best choice because roflumilast reduces exacerbation risk in severe COPD with chronic bronchitis without increasing pneumonia risk. Option A and Option B are incorrect because adding an inhaled steroid would further increase his risk for lower respiratory tract infections. Option D is inappropriate due to the long-term adverse effects of systemic steroids.
Question 6
A 45-year-old with confirmed bacterial pneumonia is declining prescribed antimicrobial therapy. The patient intends to use only herbal remedies and wishes to leave the clinic. The nurse practitioner evaluates the risk of clinical deterioration. Which action best upholds ethical practice?
- A) Provide education on disease progression and offer a follow-up appointment for reassessment.✓
- B) Withhold the follow-up appointment until the patient agrees to take the antibiotics.
- C) Contact local adult protective services to report the patient's dangerous medical neglect.
- D) Prescribe a placebo antibiotic to ensure the patient receives some psychological benefit.
💡 Key Takeaway
Beneficence requires offering ongoing care and monitoring even when a patient autonomously refuses recommended treatments.
Show rationale
A competent adult has the right to refuse standard care, exercising their healthcare autonomy. The NP's role in evaluating this outcome is to ensure the refusal is fully informed and to maintain clinical beneficence by leaving the door open for future care. Option A achieves this ethical balance. Option B is coercive, punitive, and violates nonmaleficence. Option C is inappropriate because competent adults are allowed to make poor medical decisions. Option D is deceptive and violates informed consent.
Question 7
A 40-year-old female is evaluated for a chronic cough for 10 weeks. She denies nasal symptoms or heartburn. Her spirometry is entirely normal, and a methacholine challenge test is negative. However, an induced sputum analysis reveals an eosinophil count of 4%. Which of the following is the most appropriate management strategy?
- A) Initiate a trial of inhaled corticosteroid therapy.✓
- B) Prescribe an empiric daily proton pump inhibitor.
- C) Recommend a daily oral first-generation antihistamine pill.
- D) Order a high-resolution chest computed tomography scan.
💡 Key Takeaway
Non-asthmatic eosinophilic bronchitis presents with sputum eosinophilia but normal airway responsiveness, and responds to inhaled corticosteroids.
Show rationale
This patient presents with non-asthmatic eosinophilic bronchitis, a distinct condition characterized by chronic cough and airway eosinophilia without the airway hyperresponsiveness seen in asthma. Because the methacholine challenge is negative, asthma is ruled out, but the presence of sputum eosinophils confirms the diagnosis and dictates treatment with inhaled corticosteroids. Option B is incorrect because a proton pump inhibitor treats acid reflux, which does not cause sputum eosinophilia. Option C is incorrect as antihistamines target upper airway cough syndrome, lacking relevance to this lower airway inflammatory profile. Option D is incorrect because high-resolution imaging is unnecessary for a confirmed inflammatory diagnosis lacking structural red flags. Recognizing this specific bronchitis variant allows the clinician to prescribe the correct anti-inflammatory therapy, resolving the cough effectively while avoiding ineffective treatments like bronchodilators.
Question 8
An 82-year-old female presents with acute functional decline and lethargy over two days. She denies cough or dyspnea. Her temperature is 98.2°F and respiratory rate is 26 breaths/minute. Chest radiography reveals diffuse interstitial infiltrates. What underlying age-related physiological change best accounts for her lack of classic infectious symptoms?
- A) Increased baseline production of systemic pro-inflammatory cytokines
- B) Blunted hypothalamic thermoregulatory response and immunosenescence✓
- C) Enhanced alveolar macrophage phagocytic activity and proliferation
- D) Accelerated mucociliary clearance within the lower respiratory tract
💡 Key Takeaway
Older adults often lack fever during pneumonia due to age-related blunting of the hypothalamic thermoregulatory response.
Show rationale
Older adults frequently present with atypical manifestations of pneumonia, such as functional decline and tachypnea, rather than a classic fever and productive cough. Option B is correct because immunosenescence and blunted thermoregulation prevent the robust immune and febrile responses typically seen in younger patients. Option A is incorrect because while older adults have chronic low-grade inflammation, their acute cytokine response to new infections is actually delayed or diminished, not increased. Option C is incorrect because aging decreases, rather than enhances, alveolar macrophage function, which contributes to increased susceptibility to infection. Option D is incorrect because mucociliary clearance significantly declines with age, impairing the mechanical removal of pathogens and increasing the risk for lower respiratory tract infections.
Question 9
A 68-year-old patient with a history of severe chronic obstructive pulmonary disease is on day seven of oral levofloxacin therapy for pneumonia. The fever has resolved, but the patient reports a return to baseline exertional dyspnea levels. Which of the following is the most appropriate action?
- A) Prescribe a second course of oral levofloxacin.
- B) Conclude the current antibiotic therapy as planned.✓
- C) Initiate a long-term prophylactic macrolide daily dose.
- D) Order a high-resolution computed tomography scan today.
💡 Key Takeaway
In patients with underlying lung disease, returning to baseline respiratory symptoms indicates successful resolution of acute pneumonia.
Show rationale
Evaluating symptom resolution in a patient with underlying chronic lung disease requires establishing their baseline functional status. For a patient with severe COPD, a return to their baseline exertional dyspnea and chronic morning sputum production, coupled with the resolution of acute symptoms like fever, indicates successful treatment of the pneumonia. Concluding the antibiotic therapy as planned is the correct action. Prescribing a second course of levofloxacin is inappropriate and increases the risk of adverse effects and antimicrobial resistance. Initiating a long-term prophylactic macrolide is reserved for specific patients with frequent COPD exacerbations, not as a routine post-pneumonia intervention. Ordering a high-resolution computed tomography scan is unnecessary for a patient who has clinically improved and returned to their pre-infection baseline, as it offers no immediate clinical benefit.
Question 10
A 48-year-old female with suspected community-acquired pneumonia undergoes a chest radiograph. The imaging reveals an infiltrate that obscures the right heart border but leaves the right hemidiaphragm clearly visible. Which anatomical location is primarily affected?
- A) Right upper lobe of the lung
- B) Right middle lobe of the lung✓
- C) Right lower lobe of the lung
- D) Right apical segment of the lung
💡 Key Takeaway
Obscuration of the right heart border on a chest radiograph indicates right middle lobe consolidation.
Show rationale
The silhouette sign helps localize pulmonary opacities. An infiltrate that obscures the right heart border indicates right middle lobe involvement, as this lobe sits anatomically adjacent to the right atrium. Option A is incorrect because right upper lobe infiltrates typically obscure the ascending aorta. Option C is incorrect because right lower lobe infiltrates typically obscure the right hemidiaphragm, which is preserved in this patient. Option D is incorrect because apical segments do not border the heart.
