Q

A 53-year-old male with a 45 pack-year smoking history presents to the nurse practitioner’s office for a follow-up visit. This patient had a recent emergency department admission for exertional dyspnea that has progressed to dyspnea at rest and a cough for 1 month. The nurse practitioner received the chest radiograph report, which demonstrates a suspicious nodule in the right hilar region. The nurse practitioner suspects small cell lung cancer and understands that:

  1. Small-cell lung cancer differs from non-small-cell lung cancer because small-cell lung cancer grows slowly.
  2. Small-cell lung cancer responds well to chemotherapy and radiation therapy.
  3. Small-cell lung cancer is generally not associated with distinct paraneoplastic syndromes.
  4. Small-cell lung cancer metastasizes slowly.
A

2. Small-cell lung cancer responds well to chemotherapy and radiation therapy.

Small-cell lung cancer responds well to chemotherapy and radiation therapy. Small-cell lung cancer (also called oat cell cancer) and non-small-cell lung cancer are the two main types of lung cancer.

Q

Screening for latent tuberculosis infection (LTBI) is recommended:

  1. In persons at risk of recent infection and patients infected with HIV.
  2. Groups with an increased flow of progression to active disease.
  3. Persons with nocturnal coughing.
  4. In persons whose CD4 cell count increases to counts of > 600 cells/µL.
A

1. In persons at risk of recent infection and patients infected with HIV.

According to the Center for Disease Control and Prevention, screening for latent tuberculosis infection (LTBI) is recommended for HIV-infected persons and those at risk of recent LTBI infection. The diagnosis of LTBI is based on information gathered from the medical history, a tuberculin skin test (TST) or interferon gamma release assay (IGRA) result, chest radiographs, physical examination, and in certain circumstances, sputum examinations. The presence of TB must be excluded before treatment for LTBI is initiated, because failure to do so may result in inadequate treatment and development of drug resistance. A TST reaction of ³ 5 mm of induration is considered positive in patients with HIV.

Q

IgE is the antibody responsible for activation of allergic reactions and is:

  1. Important to the development and persistence of inflammation.
  2. A critical component of lung function.
  3. Important for selecting inhaled corticosteroid dosages.
  4. A tool for determining airway remodeling.
A

1. Important to the development and persistence of inflammation.

When IgE receptors are activated with an antigen, they release mediators that initiate acute bronchospasms and release pro-inflamatory cytokines affecting underlying airway inflammation.

Q

Measurements of fractional exhaled NO (FeNO) are:

  1. Useful for monitoring responses to asthma treatment because of the association between FeNO and the presence of inflammation in asthma.
  2. Identified as a pathogenesis of allergic diseases.
  3. Responsible for activation of allergic reactions.
  4. Important in promoting Th1 cytokines to avoid asthma exacerbations.
A

1. Useful for monitoring responses to asthma treatment because of the association between FeNO and the presence of inflammation in asthma.

Measurements of fractional exhaled NO (FeNO) is very useful for monitoring the response to asthma treatment because of the association between FeNO and the presence of inflammation in asthma. Many insurance companies pay for this tool, which is helpful in evaluating the current treatment regimen, response to treatment over a period of time, and possibly adherence.

Q

In patients with asthma, the nurse practitioner understands that:

  1. Beta-blockers can cause increased bronchial obstruction, airway reactivity, and resistance to the effects of inhaler or oral beta receptor agonists.
  2. Topical ophthalmic administration of nonselective beta-blockers are in patients with COPD and not asthma.
  3. Pulmonary function tests must be performed every 3 to 4 weeks for patients with asthma who are prescribed a beta-blocker.
  4. Significant respiratory symptoms occur only in patients with moderate and severe persistent asthma who are prescribed a beta-blocker.
A

1. Beta-blockers can cause increased bronchial obstruction, airway reactivity, and resistance to the effects of inhaler or oral beta receptor agonists.

Beta-blockers can cause increased bronchial obstruction, airway reactivity, and resistance to the effects of inhaled or oral beta receptor agonists in patients with asthma. Topical ophthalmic administration of nonselective beta-blockers for the treatment of glaucoma can lead to exacerbated asthma but not exacerbated COPD. Pulmonary function testing is not indicated every 3 to 4 weeks in patients taking beta-blockers. Adverse reactions can occur in intermittent asthma, mild persistent, moderate persistent asthma, and severe persistent asthma.

46
Q

Patients with chronic bronchitis tend to have complications of which of the following?

  1. Chronic hypoxemia and hypocapnia
  2. Peripheral edema from cor pulmonale
  3. Ocular swelling and post–nasal drainage
  4. Muscle wasting and chronic, productive cough with large amounts of sputum
A

2. Peripheral edema from cor pulmonale

Patients with chronic bronchitis may be obese, cough frequently and expectoration are typical, accesory muscles of repiration is common. These patients usually have signs of right heart failure, such as edema and cyanosis.

47
Q

Ausculatory findings characterized as low-pitched, loud, generally heard on inspiration, and often cleared with cough is known as what?

  1. Wheezing
  2. Crackles
  3. Vesicular
  4. Rhonchi
A

4. Rhonchi

Rhonchi is described as low-pitched and loud, generally heard on inspiration, and often cleared with cough. It is important to ask the patient to cough and then repeat auscultation of the lungs.

48
Q

The therapeutic action of ipratropium bromide is:

  1. Activation of β1 receptors that degrades cycle monophosphate.
  2. the bronchodilatory effect due to activation of β1 receptors.
  3. inducing positive inotropic, chronotropic output of the cardiac muscle.
  4. that it promotes the degradation of cyclic guanosine monophosphate and the activation of beta2-adrenergic receptors on airway smooth muscle.
A

4. that it promotes the degradation of cyclic guanosine monophosphate and the activation of beta2-adrenergic receptors on airway smooth muscle.

Ipratropium bromide promotes the degradation of cyclic guanosine monophosphate and activation of beta2-adrenergic receptors on airway smooth muscle.

49
Q

Systemic manifestations of comorbid diseases have a significant influence on the management of asthma. The FNP understands comorbidities should be considered, especially with uncontrolled asthma, and that it includes all except which of the following?

  1. Gastroesophageal reflux disease
  2. Diabetes mellitus
  3. Allergic rhinitis
  4. Vocal cord dysfunction
A

4. Vocal cord dysfunction

Several comorbidities of asthma include gastroesophageal reflux disease, diabetes mellitus, and allergic rhinitis. Vocal cord dysfunction can mimic asthma.
