Question 1 of 5
Which of the following drugs has a therapeutic effect that prevents thromboembolic events?
Correct Answer: A
Rationale: In this question, the correct answer is A) Warfarin. Warfarin is a commonly prescribed anticoagulant medication that works by inhibiting the synthesis of clotting factors in the liver, thereby preventing the formation of blood clots and reducing the risk of thromboembolic events such as strokes and myocardial infarctions. Option B) Amlodipine is a calcium channel blocker used to treat hypertension and angina by relaxing blood vessels, but it does not have a direct effect on preventing thromboembolic events. Option C) Nitroglycerin is a vasodilator primarily used to relieve angina symptoms by dilating blood vessels and improving blood flow to the heart. It does not directly prevent thromboembolic events. Option D) Clopidogrel is an antiplatelet medication that inhibits platelet aggregation, thereby reducing the risk of blood clots. While clopidogrel is effective in preventing thromboembolic events, in this question, warfarin is a more appropriate choice as it acts on a different pathway in the coagulation cascade. Understanding the mechanisms of action of different pharmacological agents is essential for nurses and healthcare professionals to make informed decisions regarding drug therapy and patient care. In this context, knowing the specific effects of each medication and their indications is crucial for providing safe and effective patient care.
Question 2 of 5
Which of the following medications is a bronchodilator?
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.
Question 3 of 5
When teaching a patient to take their own pulse, which medication should the nurse instruct them to monitor? (Hint: if pulse is <60 or >100, the patient should contact their healthcare provider before taking the medication)
Correct Answer: A
Rationale: It is essential for patients taking Digoxin to monitor their pulse regularly. If their pulse falls below 60 or exceeds 100 beats per minute, they should contact their healthcare provider immediately. This is crucial due to Digoxin's potential to affect heart rate, making pulse monitoring a vital aspect of patient care while on this medication.
Question 4 of 5
What should a patient avoid while taking Angiotensin-converting enzymes?
Correct Answer: A
Rationale: Patients taking Angiotensin-converting enzyme (ACE) inhibitors should avoid salt substitutes because they can contain potassium chloride, which may lead to hyperkalemia. It is important to restrict potassium-rich foods while on ACE inhibitors, but the primary concern with salt substitutes is their potassium content.
Question 5 of 5
What is one of the therapeutic uses of Valproate?
Correct Answer: A
Rationale: Valproate, also known as Valproic acid, is commonly used in medicine for the suppression of seizure activity. It is an anticonvulsant medication that helps manage and prevent seizures in various conditions such as epilepsy. While it is not used for replacing hypothyroidism, maintaining blood glucose levels, or lowering blood pressure, its primary therapeutic use is in managing seizures.
