A nurse is providing teaching to a client who has asthma and is beginning to take montelukast. Which of the following statements by the client indicates an understanding of the teaching?

Correct Answer: B

Rationale: Montelukast is typically taken once daily in the evening for long-term control of asthma symptoms. It helps prevent asthma attacks by reducing inflammation in the airways. While montelukast can also be used for exercise-induced bronchospasm in some cases, it is generally not a rescue medication and should be taken regularly, not on an as-needed basis.

Correct Answer: B

Rationale: Shaking the albuterol inhaler before use is essential to ensure that the medication is evenly mixed and properly delivered when inhaled. This maximizes the effectiveness of the medication in opening the airways and relieving symptoms of bronchospasm.

Correct Answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

Correct Answer: A

Rationale: Furosemide, a loop diuretic, can cause potassium loss. Clients should increase their intake of potassium-rich foods to prevent hypokalemia.

Correct Answer: C

Rationale: The correct instruction for a client taking Methotrexate is to avoid alcohol, as it can increase the risk of liver damage. Alcohol consumption should be avoided to prevent potential adverse effects while on this medication.
