What is a side effect of nitroglycerin?
Urinary frequency
Dry cough
Hypoglycemia
Flushing
The Correct Answer is D
A. Urinary frequency: Nitroglycerin does not affect renal function in a way that would cause increased urination. Urinary frequency is not a recognized side effect of nitroglycerin therapy.
B. Dry cough: Dry cough is commonly associated with ACE inhibitors, not nitroglycerin. Nitroglycerin’s pharmacologic effects do not typically involve the respiratory system in this manner.
C. Hypoglycemia: Nitroglycerin does not alter blood glucose levels. Hypoglycemia is unrelated to its mechanism of action as a vasodilator.
D. Flushing: Flushing is a common side effect of nitroglycerin due to peripheral vasodilation. The widening of blood vessels increases blood flow to the skin, resulting in warmth and redness, which is typically mild and transient.

Correct Answer is B
Explanation
. Hypertension: Methylprednisolone is a corticosteroid used primarily for its anti-inflammatory and immunosuppressive effects. While long-term use can contribute to elevated blood pressure, hypertension itself is not an indication for this medication.
B. Asthma exacerbation: Methylprednisolone is indicated for the management of acute asthma exacerbations because it reduces airway inflammation, improves airflow, and decreases the severity and duration of symptoms. It is commonly used when inhaled therapies are insufficient.
C. Bacterial pneumonia: While corticosteroids may sometimes be used as adjunct therapy in severe bacterial pneumonia, antibiotics are the primary treatment. Methylprednisolone is not indicated as first-line therapy for bacterial infections.
D. Type 1 diabetes mellitus: Type 1 diabetes is managed with insulin therapy. Methylprednisolone does not treat the underlying autoimmune destruction of pancreatic beta cells and can actually worsen glycemic control due to its hyperglycemic effects.
Correct Answer is D
Explanation
A. Lethargy: Lethargy is not typically associated with overuse of albuterol. Albuterol is a beta-2 agonist that primarily stimulates the sympathetic nervous system, which usually increases alertness rather than causing sedation.
B. Weight gain: Weight gain is not a known side effect of albuterol overuse. Albuterol’s effects are more acute and related to cardiovascular and respiratory systems rather than fluid retention or metabolic changes that cause weight gain.
C. Hypotension: Albuterol can cause mild vasodilation, but hypotension is not a common clinical finding with overuse. Instead, sympathetic stimulation often leads to increased heart rate and blood pressure fluctuations rather than consistent low blood pressure.
D. Tachycardia: Overuse of albuterol can lead to tachycardia because it stimulates beta-1 receptors in the heart along with beta-2 receptors in the lungs. Frequent use may indicate poor asthma control and can manifest as palpitations, elevated heart rate, and potential arrhythmias.
