A nurse is reviewing a list of current medications for a client who is starting therapy with furosemide. Which of the following medications should the nurse identify as being contraindicated?
Lithium carbonate
Albuterol
Levothyroxine
Cetirizine
The Correct Answer is A
A. Furosemide can decrease the renal clearance of lithium, leading to increased lithium levels in the blood. This can potentiate the toxic effects of lithium, such as neurotoxicity and cardiac toxicity. Therefore, concurrent use of furosemide and lithium is generally contraindicated, and caution is advised. The nurse should identify lithium carbonate as contraindicated in this scenario.
B. Albuterol is a bronchodilator commonly used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). There are no significant contraindications between albuterol and furosemide.
C. Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism. There are no significant contraindications between levothyroxine and furosemide.
D. Cetirizine is an antihistamine used to treat allergies and allergic reactions. There are no significant contraindications between cetirizine and furosemide. They are generally considered safe to use together.

Correct Answer is ["A","B","C"]
Explanation
Albuterol belongs to a class of medications known as beta-adrenergic agonists, specifically beta-2 selective agonists. When inhaled, albuterol binds to beta-2 adrenergic receptors located on the smooth muscle cells lining the airways in the lungs. Activation of these receptors leads to relaxation of the smooth muscles surrounding the bronchial tubes, causing them to widen (bronchodilation). By dilating the airways, albuterol helps to reduce airway resistance and increase airflow into and out of the lungs, making it easier to breathe during an asthma attack.
One should hold breath for 5 to 10 seconds after inhalation of the puff.
Salmeterol is a long-acting beta-adrenergic agonist (LABA) bronchodilator commonly used for the maintenance treatment of asthma and chronic obstructive pulmonary disease (COPD). Salmeterol is usually prescribed for twice-daily dosing.
One should wait for 2 minutes between two puffs.
Fluticasone is a corticosteroid medication that is inhaled into the lungs to reduce inflammation in the airways. If these particles remain in the mouth, they can increase the risk of developing oral thrush, which is a fungal infection caused by Candida albicans. Rinsing the mouth with water after using the inhaler helps to remove any residual medication particles, reducing the risk of oral thrush.
Correct Answer is D
Explanation
D. The expected therapeutic effect of montelukast is the reduction of bronchial inflammation. By blocking leukotriene receptors, montelukast helps to prevent the constriction of airway muscles, decrease mucus secretion, and reduce inflammation in the airways. This can lead to improved asthma control and symptom management.
A. Montelukast is not indicated for the treatment of gastric acid-related conditions such as gastroesophageal reflux disease (GERD) or peptic ulcers.
B. Montelukast is not typically associated with peripheral vasodilation. Its primary mechanism of action involves blocking the action of leukotrienes, which are inflammatory mediators involved in allergic and asthmatic reactions.
C. Montelukast does not affect white blood cell (WBC) count.
