1. Monitor Digoxin levels with:
x x x x
A. Albuterol
x
B. Theophylline
x
C. Prednisone
x
D. Montelukast
x
Answer: A x
Rationale: Albuterol and other beta-agonists can cause hypokalemia, which
x x x x x x x x
increases the risk of digoxin toxicity. When beta-agonists stimulate beta-2
x x x x x x x x x x
receptors, they promote potassium uptake into cells, lowering serum
x x x x x x x x x
potassium. Low potassium levels increase the sensitivity of cardiac muscle to
x x x x x x x x x x x
digoxin, potentially causing toxicity even at therapeutic levels. Patients
x x x x x x x x x
taking both medications should have their potassium and digoxin levels
x x x x x x x x x x
monitored.

2. Pheochromocytoma patients should avoid due to risk of HTN crisis:
x x x x x x x x x x
A. Beta 2 Agonists
x x x
B. Anticholinergics
x
C. Inhaled corticosteroids
x x
D. Mast cell stabilizers
x x x
,Answer: A x
Rationale: Beta-2 agonists can stimulate catecholamine release, which can
x x x x x x x x
precipitate a hypertensive crisis in patients with pheochromocytoma (a
x x x x x x x x x
catecholamine-secreting tumor). These medications increase sympathetic
x x x x x x
nervous system activity, potentially causing massive release of
x x x x x x x x
catecholamines from the tumor. Patients with known or suspected
x x x x x x x x x
pheochromocytoma should avoid beta-2 agonists and use alternative
x x x x x x x x
medications for respiratory conditions.

3. Use with caution or avoid with African Americans:
x x x x x x x x
A. Short-acting beta agonists
x x x
B. Long-acting beta agonists
x x x
C. Inhaled corticosteroids
x x
D. Leukotriene receptor antagonists
x x x
Answer: B x
Rationale: Long-acting beta agonists (LABAs) should be used with caution
x x x x x x x x x
or avoided in African American patients due to an increased risk of severe
x x x x x x x x x x x x x
asthma exacerbations and death. Studies have shown that African American
x x x x x x x x x x
patients have a higher risk of fatal asthma events when using LABAs as
x x x x x x x x x x x x x
monotherapy. African American patients should always use LABAs in
x x x x x x x x x
combination with an inhaled corticosteroid (ICS) to reduce this risk.
x x x x x x x x x x
, 4. Black Box for long acting beta agonists:
x x x x x x x
A. Increased risk of nephrotoxicity
x x x x
B. Increased risk of death from asthma
x x x x x x
C. Increased risk of cardiac arrhythmias
x x x x x
D. Increased risk of hepatotoxicity
x x x x
Answer: B x
Rationale: Long-acting beta agonists (LABAs) carry a black box warning for
x x x x x x x x x x
an increased risk of asthma-related death. The warning is based on the
x x x x x x x x x x x x
SMART study (Salmeterol Multicenter Asthma Research Trial), which found
x x x x x x x x x
an increased risk of asthma-related mortality when LABAs were used without
x x x x x x x x x x x
concomitant inhaled corticosteroids. LABAs should only be used as add-on
x x x x x x x x x x
therapy for patients whose asthma is not controlled with ICS alone. They
x x x x x x x x x x x x
should never be used as monotherapy for asthma.
x x x x x x x x
5. Bronchodilator for patients on propranolol:
x x x x x
A. Albuterol
x
B. Ipratropium (Atrovent)
x x
C. Theophylline
x
D. Salmeterol
x
Answer: B x
