Correct Answer: C

Rationale: Headache is a common side effect associated with the initial therapy of Nitroglycerine due to its vasodilatory properties. The vasodilation caused by Nitroglycerine leads to relaxation of blood vessels, including those in the head, which can result in headaches. This side effect is considered normal and is often transient, diminishing with continued use of the medication.

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: B

Rationale: When a client is prescribed Digoxin, it is essential to monitor their heart rate before each dose. Changes such as a heart rate below 60 bpm should be reported to the healthcare provider promptly. This is crucial because Digoxin can affect heart rhythm, and monitoring the heart rate helps in identifying any potential issues early on.

Correct Answer: A

Rationale: Albuterol is classified as a bronchodilator, which is commonly used to treat conditions like asthma by relaxing the muscles in the airways and increasing airflow to the lungs. Omeprazole is a proton pump inhibitor used to reduce stomach acid production, while ondansetron is an anti-nausea medication, and senna is a laxative.

Correct Answer: C

Rationale: When two inhaled medications are prescribed, waiting 5 minutes between medications allows for optimal absorption and effectiveness of each medication. This ensures that each medication can work properly without interference from the other, improving the client's respiratory condition.
