Question

A nurse is reviewing pulmonary function test results for a patient with a long history of smoking who reports progressive dyspnea and a chronic cough. The patient receives a bronchodilator before repeat spirometry. Which result would best support the nurse's suspicion of COPD?

Answer 1

Correct Answers:

FEV1/FVC remains at 65% after the bronchodilator

Rationale :

🔶COPD is characterized by persistent airflow obstruction, demonstrated by a reduced FEV1/FVC ratio that does not fully normalize after administration of a bronchodilator.

🔶A post-bronchodilator FEV1/FVC ratio below 0.70 (70%) supports the presence of persistent airflow limitation consistent with COPD in the appropriate clinical setting.

🔶A ratio that remains at 65% despite bronchodilator administration indicates that the obstruction remains significant rather than being completely reversible.

🔶The client's long smoking history, progressive dyspnea, and chronic cough further support a clinical suspicion of COPD.

🔶Persistent post-bronchodilator obstruction therefore distinguishes COPD from conditions with more completely reversible airflow limitation.

Answer 2

Correct Answers:

The client has had 3 consecutive negative AFB sputum specimens

Rationale :

✳️ Clients with infectious pulmonary tuberculosis require airborne precautions because Mycobacterium tuberculosis is transmitted through small airborne particles.

✳️ Three appropriately collected consecutive sputum specimens that are negative for acid-fast bacilli (AFB) provide strong evidence that the client's infectiousness has substantially decreased.

✳️ Specimens are traditionally collected several hours apart, with at least one obtained in the early morning, according to facility and public-health protocols.

✳️ Decisions about discontinuing isolation also take into account adequate antituberculosis therapy and clinical improvement, but negative sputum testing is the strongest option provided.

✳️ Three consecutive negative AFB sputum specimens therefore best support removal of airborne isolation precautions.

Answer 3

Correct Answers:

"Persistent hoarseness for more than 2 weeks should be evaluated."

Rationale :

🧿 Persistent hoarseness or voice change in a client with a substantial tobacco history warrants prompt evaluation because it can indicate laryngeal pathology, including malignancy.

🧿 Tobacco exposure is an important risk factor for laryngeal cancer, making an unexplained persistent voice change particularly concerning.

🧿 Early laryngeal lesions may first present with hoarseness before more advanced symptoms such as dysphagia, neck mass, or airway problems develop.

🧿 The nurse should therefore encourage timely medical evaluation rather than assuming the symptom is an expected consequence of smoking.

🧿 Among the available options, recommending evaluation of persistent hoarseness is the safest and most clinically appropriate response.

Answer 4

Correct Answers:

Human Immunodeficiency Virus (HIV) infection leading to immune suppression

Rationale :

♦️ Kaposi sarcoma is strongly associated with infection by human herpesvirus 8 (HHV-8), particularly in people who are significantly immunocompromised.

♦️ Clients with advanced HIV infection/AIDS have historically been at substantially increased risk because impaired cellular immunity allows HHV-8-associated tumor development.

♦️ Kaposi sarcoma can produce characteristic red, purple, or brown vascular lesions involving the skin, mucous membranes, and internal organs.

♦️ Effective antiretroviral therapy has greatly reduced the incidence of AIDS-associated Kaposi sarcoma by improving immune function.

♦️ HIV-related immune suppression is therefore the strongest risk factor among the options provided.

Answer 5

Correct Answers:

Bronchodilator therapy

Rationale :

🖍️ Bronchodilators are foundational pharmacologic treatment for COPD because they decrease airway smooth-muscle tone and improve expiratory airflow.

🖍️ A client who remains symptomatic with daily activities despite smoking-cessation and self-management education generally requires pharmacologic treatment to control dyspnea.

🖍️ Long-acting bronchodilators, such as a LABA or LAMA, are commonly used for ongoing symptom control according to the client's symptom burden and exacerbation history.

🖍️ Bronchodilator therapy can reduce breathlessness, improve exercise tolerance, and improve quality of life even though it does not reverse the underlying structural lung damage.

🖍️ Because no maintenance inhaled therapy is described in the scenario, bronchodilator treatment is the expected next step.

Answer 6

Correct Answers:

Assess the patient's respiratory status and notify the provider of the change

Rationale :

♠️ New drowsiness and confusion after increasing oxygen in a client with COPD can indicate worsening ventilation and possible carbon dioxide retention.

♠️ The nurse should immediately assess respiratory rate, depth, effort, breath sounds, oxygen saturation, level of consciousness, and other signs of respiratory deterioration.

♠️ Arterial blood gases may be required to determine whether hypercapnia and respiratory acidosis are developing.

♠️ Oxygen should be carefully titrated to the prescribed target while avoiding both untreated hypoxemia and unnecessarily excessive oxygen administration.

♠️ Immediate respiratory assessment followed by prompt provider notification is therefore the safest response to this acute neurologic change.

Answer 7

Correct Answers:

Irregular borders

Rationale :

🧡 Irregular or poorly defined borders are one of the classic warning features evaluated when assessing a pigmented lesion for possible melanoma.

🧡 The ABCDE assessment considers Asymmetry, Border irregularity, Color variation, Diameter, and Evolution of a lesion.

🧡 Malignant melanocytic lesions may have scalloped, notched, blurred, or uneven borders rather than smooth, clearly defined edges.

🧡 Any suspicious lesion should be assessed along with changes in size, color, shape, bleeding, or evolution over time.

🧡 Irregular borders therefore represent the finding among the choices that most specifically raises concern for melanoma.

Answer 8

Correct Answers:

The patient performs three attempts and records the highest reading.

Rationale :

✍️ A peak flow meter measures the client's maximum expiratory flow rate during a forceful, rapid exhalation.

✍️ The client should stand or sit upright, move the indicator to the baseline, take a deep breath, seal the lips around the mouthpiece, and blow out as hard and fast as possible.

✍️ The measurement should be repeated three times to account for effort-dependent variation.

✍️ The highest of the three readings is recorded and compared with the client's personal best to determine the appropriate asthma action-zone classification.

✍️ Performing three attempts and recording the highest value therefore demonstrates correct peak-flow technique.

Answer 9

Correct Answers:

"This type of cancer grows rapidly and tends to metastasize early."

Rationale :

🔆 Small cell lung cancer (SCLC) is an aggressive neuroendocrine malignancy characterized by rapid cellular proliferation.

🔆 It commonly spreads early through the lymphatic and hematogenous systems, so many clients already have regional or distant disease at diagnosis.

🔆 Common metastatic sites include the brain, liver, bone, adrenal glands, and other thoracic structures.

🔆 Because SCLC is usually disseminated when discovered, treatment commonly relies on systemic chemotherapy with or without radiation therapy, rather than surgical resection.

🔆 Rapid growth and early metastasis are therefore defining clinical characteristics of small cell lung cancer.

Answer 10

Correct Answers:

Confirm tube placement by x-ray

Rationale :

📘 Radiographic confirmation is the most reliable method for verifying initial placement of a newly inserted nasogastric tube before it is used for feeding or medication administration.

📘 An incorrectly positioned NG tube can enter the respiratory tract, creating a serious risk for aspiration, pneumonitis, or direct pulmonary administration of feeding.

📘 X-ray confirmation identifies the course and distal tip of the tube and verifies that it terminates in the appropriate gastrointestinal location.

📘 After initial placement has been radiographically confirmed, bedside methods such as external-length assessment and aspirate characteristics can help monitor for later displacement according to policy.

📘 The nurse should therefore obtain confirmation of correct placement by x-ray before initiating the first enteral feeding through a newly placed NG tube.
