Correct Answers
Breath sounds auscultated over the periphery of the lung fields are quiet and wispy
during the inspiratory phase, followed by a short, almost silent expiratory phase. These
breath sounds are considered:
vesicular
How should a 20 yr old college age student who presents with cough, night sweats, and
weight loss be screened for TB?
tb skin test
Which medication below is contraindicated in an asthma patient because it may
increase risk of sudden death if used alone?
long-acting bronchodilator
A 55-year-old male presents to your primary care clinic complaining of a cough for 3
months. He is a diabetic and is currently taking lisinopril, atorvastatin, and metformin.
He denies dyspnea, chest pain, and productive cough. He was recently diagnosed with
diabetes and has started all 3 of these medications within the last 4 months. The
patient's vital signs are within normal limits, and his chest x-ray is negative. What is the
etiology of the patient's cough?
Lisinopril
Rationale: The patient has had a chronic cough for approximately as long as he has been
taking his angiotensin-converting enzyme (ACE) inhibitor, so it is likely a side effect of this
medication.
, The well-established risk factor(s) for nosocomial pneumonia caused by a multidrug-
resistant organism is (are):
Antibiotic exposure and a hospital stay of more than 1 week.
Rationale: Treatment of nosocomial pneumonia is complicated by the frequent involvement
of multidrug-resistant organisms. Prior exposure to antibiotics and a hospital stay of more
than 1 week are well-established risk factors for infection with these organisms.
A definitive test for cystic fibrosis (CF) is:
The sweat test.
Rationale: The definitive tests for CF are the sweat test and DNA analysis. The diagnosis is
confirmed by a positive sweat test or by confirming the presence of two of the recognized CF
mutations in DNA, one each on the maternally and paternally derived chromosome 7. Sweat
testing can be performed at any age. However, newborns in the first few weeks of life may
not produce a large enough volume of sweat to analyze, but in those who do, the results will
be accurate. Immunoreactive trypsinogen (IRT) levels are elevated in most infants with CF
for the first several weeks of life; however, this test has relatively poor specificity because as
many as 90% of the positives on the initial screen are false-positives. Early diagnosis of CF
improves the poor prognosis for untreated CF. If untreated, most clients die by age 1 to 2
years. With current care, median life expectancy is about 37 years.
When you suspect a diagnosis of asthma, which test is the most appropriate to order to
confirm the diagnosis?
Spirometry.
Martin, age 76, has just been given a diagnosis of pneumonia. Which of the following is
an indication that he should be hospitalized?
