Which of the following side effects would you most likely expect when providing an asthmatic patient with continuous nebulizer therapy?
Which of the following side effects would you most likely expect when providing an asthmatic patient with continuous nebulizer therapy?
Asthma is treated with albuterol. This drug is a beta-2 agonist, which works to relax smooth muscle in the lungs, and open up the airways. A consequence of this drug is the beta-2 effects on the heart. Beta-2 on the heart causes an increase in heart rate (tachycardia) and is a common side effect seen in the treatment of asthmatics.

What is the final stage of a pertussis infection?
What is the final stage of a pertussis infection?
The final stage of a pertussis infection is known as the convalescent phase. This occurs for 2-6 weeks, after the paroxysmal stage of the disease. During this time coughing decreases, and paroxysms are less severe. The infected individual may experience increased susceptibility to upper and lower respiratory conditions for as much as 6 months after resolution of the infection.

What is the "hygiene hypothesis" in asthma?
What is the "hygiene hypothesis" in asthma?
Incidence of asthma is lower in populations exposed to an abundance of microbes from a young age. The "hygiene hypothesis" suggests that early immune stimulation by multiple forms of infectious agents may push a Th1 phenotype, reducing the Th2 (allergic) response.

A patient has been administered isoniazid for the treatment of tuberculosis (TB). Which statement made by the nurse would be the most appropriate when teaching the client about this medication?
A patient has been administered isoniazid for the treatment of tuberculosis (TB). Which statement made by the nurse would be the most appropriate when teaching the client about this medication?
Isoniazid is a bactericidal drug that is given for tuberculosis that has several adverse effects including peripheral neuropathy. This drug is usually administered in conjunction to other antitubercular drugs. Pyridoxine (vitamin B6) is recommended to be taken in conjunction with isoniazid to prevent neurotoxicity.
Isoniazid is relatively inexpensive and may be taken orally or intravenously. It is not necessary to be taken under direct observation, and is usually dosed according to type of disease (active versus latent). The typical duration of administration is roughly 26 weeks. Color blindness is not associated with isoniazid treatment.

At what stage are antibiotics effective in treatment of pertussis?
At what stage are antibiotics effective in treatment of pertussis?
Antibiotics have been shown to have very little effectiveness in treating a pertussis infection older than four weeks. Because of this, treatment with antibiotics to individuals that have been symptomatic for longer than four weeks is not generally recommended.

A 45 year old male with COPD presents to the hospital with an exacerbation of his lung condition. He is in respiratory distress and the physician recommends he sit leaning forward. What is the purpose of sitting like this?
A 45 year old male with COPD presents to the hospital with an exacerbation of his lung condition. He is in respiratory distress and the physician recommends he sit leaning forward. What is the purpose of sitting like this?
COPD is a chronic lung condition marked by air trapping. Patients with COPD are instructed to sit in the "tripod" position to help them exhale air. Patients sit and lean forward to help maximize air exiting from the lungs.

What is the inspiratory reserve volume?
What is the inspiratory reserve volume?
The inspiratory reserve volume for the average adult is roughly 3100mL. It is tested using pulmonary function tests. The inspiratory reserve volume is the amount of air able to be inhaled after a regular inhalation. This is in contrast to the expiratory reserve volume, which is the amount of air that can be exhaled after a regular exhalation.

You are a pulmonology nurse taking care of a patient who complains of episodic wheezing. You perform a diagnostic test in which you perform pulmonary function tests on the patient before, and after administering albuterol, a beta-2 adrenergic agonist. You note that the patient's symptoms and FEV1 readings improve drastically with bronchodilator administration. Based upon these findings, the patient most likely has which of the following?

You note that the patient's symptoms and FEV1 readings improve drastically with bronchodilator administration. Based upon these findings, the patient most likely has which of the following?
The correct answer is "Asthma." This answer is correct because asthma is an inflammatory airway condition that is characteristically improved symptomatically and quantitatively (in terms of pulmonary function tests, including FEV1 readings) with bronchodilator administration (e.g. albuterol, the beta-2 adrenergic agonist administered in this patient). In this patient who presented for evaluation of wheezing, a characteristic symptom of asthma, his substantial response to bronchodilator administration makes the likelihood of an asthma diagnosis very high.
Chronic Obstructive Pulmonary Disease (COPD) is an obstructive physiology of the airways often due to chronic tobacco smoking. While bronchodilators may be of some clinical value in these patients, their FEV1 readings characteristically do not correct after bronchodilator administration, as this is a major method in which COPD can be distinguished from asthma and other inflammatory airway conditions.
Sarcoidosis, lung cancer, and throat cancer symptoms would not necessarily improve with bronchodilator administration, nor would pulmonary function test readings in patients with these conditions.

He is not a candidate for tonsillectomy and adenoidectomy. Which of the following interventions would be the best recommendation to treat his obstructive sleep apnea?
The correct answer is "continuous positive airway pressure mask (CPAP)." This is the correct answer as a CPAP mask helps to force airway into the lungs that is otherwise obstructed by the patient's oropharyngeal anatomy at standard breathing pressures due to obstructive sleep apnea. When wearing a CPAP mask (typically when sleeping), snoring is reduced, and oxygenation is improved, allowing patients to have a more restful sleep and feel less fatigued the following day.
While medications like metoprolol, insulin, and metformin may be beneficial to the patient in treating his conditions co-morbid to obstructive sleep apnea, they do not have a direct effect on treating his sleep apnea or the resultant fatigue.
Tamsulosin is an alpha-adrenergic blocker and can be used to treat benign prostatic hyperplasia among other conditions, but not obstructive sleep apnea.

The priority for this client is to ensure a patent airway by placing him the Fowler's or semi upright seated position. Giving oxygen is warranted but will be given after the client is positioned correctly. ABG's would be helpful in this situation but it not the priority. Auscultation of breath sounds and assessment of mental status are not indicated.

Which of the following organisms causes whooping cough?
Which of the following organisms causes whooping cough?
Whooping cough, a condition that results in severe paroxysmal coughing fits followed by a long wheezing inspiratory gasp (the "whoop") is caused by the bacteria B ordetella pertussis. _Haemophilus influenza_e and Klebsiella pneumoniae both commonly cause pneumonia, and RSV is a virus that is frequently implicated in lower respiratory infections of infants and children.

How long is the incubation period for pertussis?
How long is the incubation period for pertussis?
The incubation period for pertussis, also known as the catarrhal stage, can last as little as 4 days or as long as 42 days, but a typical period is 1-3 weeks. During this stage the disease looks like a regular upper respiratory infection, with sneezing, mild cough, and runny nose. The infected individual is highly infectious at this time, with bacteria spread by airborne droplets after sneezing or cough.

In pertussis, what stage follows the incubation (also known as the catarrhal) stage?
In pertussis, what stage follows the incubation (also known as the catarrhal) stage?
After the catarrhal stage, an individual with pertussis will progress into the paroxysmal stage. It's during this stage that they will experience uncontrollable fits of 5-15 forceful coughs, followed by a "whoop" or gasp as they struggle to inhale. The force of these coughs can be such that they can result in vomiting, epistaxis, subconjunctival hemorrhage, or even broken ribs.

She lives and works in a suburb, has not traveled outside of the United States recently, and does not work in a healthcare setting. Which of the following is the most likely diagnosis?
The correct answer is "Sarcoidosis." Sarcoidosis is the correct answer as this inflammatory condition is frequently found in African-American women in their 40's who present with fatigue and shortness of breath among other symptoms, who also have erythema nodosum on the lower extremities, and have bilateral hilar infiltrates on chest x-ray. This constellation of findings is highly suggestive of sarcoidosis. Sarcoidosis results in the formation of numerous non-necrotizing granulomas, most commonly found in the lungs, that can play a role in the symptoms experienced by these patients. Other findings suggestive of sarcoidosis include elevated serum calcium levels with normal serum PTH levels.
Tuberculosis can present in a similar manner to sarcoidosis, however given the patient's suburban living environment, lack of a travel history, and lack of healthcare exposure, the likelihood of being exposed to tuberculosis is very low, making sarcoidosis a more likely etiology.
While lung cancer can present as shortness of breath with hilar infiltration in chest x-ray, in a relatively young otherwise healthy patient who also has erythema nodosum and in whom the hilar infiltrates are bilateral, sarcoidosis would be a more likely etiology.
The patient does not have any findings consistent with meningitis (leg rash in meningitis is petechial, not erythema nodosum) or pharyngitis.
