The nurse knows that montelukast (Singulair) is given for what purpose?

A. Seasonal allergy only

Montelukast may be used for the treatment of allergic rhinitis associated with seasonal allergies, but its primary use is for asthma prevention.

B. Severe asthmatic attacks

Montelukast is not typically used for the treatment of severe asthmatic attacks. Short-acting bronchodilators and systemic corticosteroids are more commonly used in this scenario.

C. Acute bronchospasm

While montelukast has a role in the prevention of bronchospasm, it is not typically used for the acute treatment of bronchospasm. Short-acting bronchodilators are more appropriate for immediate relief of bronchospasm.

D. Maintenance and prevention of asthma

Montelukast (Singulair) is used for the maintenance and prevention of asthma. It is a leukotriene receptor antagonist that works by blocking the action of leukotrienes, which are inflammatory mediators involved in the pathophysiology of asthma. By inhibiting leukotrienes, montelukast helps to reduce airway inflammation and bronchoconstriction, thereby preventing asthma symptoms.

A. To help prevent Tumor Lysis Syndrome.

Encouraging fluid intake is crucial for patients undergoing chemotherapy, especially when there's a risk of Tumor Lysis Syndrome (TLS). TLS is a potentially serious complication that can occur when cancer cells release their contents into the bloodstream, leading to metabolic imbalances. Adequate hydration helps prevent the concentration of these released substances and reduces the risk of TLS.

B. Staying hydrated decreases oral dryness that the patient may exhibit as a result of chemotherapy.

While hydration is generally important for overall well-being, oral dryness is not typically a direct consequence of bladder cancer chemotherapy. It might be a side effect of certain medications, but the primary concern in this case is likely related to preventing TLS.

C. To help prevent new onset diabetes mellitus.

The rationale for fluid intake in the context of bladder cancer chemotherapy is not typically related to preventing new onset diabetes mellitus. The primary focus is usually on managing potential side effects of chemotherapy and promoting overall health.

D. Because it is better to encourage water Vs. carbonated beverages.

While encouraging water over carbonated beverages is generally a healthy choice, the primary rationale for increased fluid intake in the context of bladder cancer chemotherapy is more specific and related to preventing Tumor Lysis Syndrome.
