Question 1 of 5
When administering a loop diuretic to a patient, it is most important for the nurse to determine if the patient is also taking which drug?
Correct Answer: D
Rationale: When administering a loop diuretic to a patient, it is crucial to determine if the patient is also taking theophylline. Loop diuretics may interact with theophylline, leading to an increase in theophylline levels in the blood. This interaction can result in elevated theophylline concentrations, potentially causing toxicity symptoms such as nausea, vomiting, headache, and arrhythmias. Therefore, monitoring the patient's theophylline levels and adjusting the dosage accordingly is essential to prevent adverse effects. It is important for healthcare providers to be aware of potential drug interactions and consider them when prescribing medications to avoid harmful complications for the patient.
Question 2 of 5
A patient wants to take garlic tablets to improve his cholesterol levels. Which condition would be a contraindication?
Correct Answer: D
Rationale: Taking garlic tablets can potentially increase the risk of bleeding during surgery due to its blood-thinning properties. This can interfere with the body's ability to clot blood properly during and after surgery, leading to excessive bleeding and complications. Therefore, scheduled surgery is a contraindication for taking garlic tablets. It is essential to inform healthcare providers about any supplements being taken before undergoing surgery to ensure safety and prevent adverse effects.
Question 3 of 5
The nurse notes in the patient™s medication orders that the patient will be starting anticoagulant therapy. What is the primary goal of anticoagulant therapy?
Correct Answer: C
Rationale: The primary goal of anticoagulant therapy is to prevent the formation of blood clots or thrombi. Anticoagulants work by inhibiting the clotting process in the blood, thereby reducing the risk of clot formation in the blood vessels. This helps to prevent conditions such as deep vein thrombosis, pulmonary embolism, stroke, and other thromboembolic events. Anticoagulants do not dissolve existing clots (thrombus), they work to prevent new clots from forming. So, the main objective of starting anticoagulant therapy in a patient is to prevent the development of thrombi.
Question 4 of 5
When taking Nitroglycerine (transdermal), you should have how many hours nitrate free each day?
Correct Answer: C
Rationale: When taking Nitroglycerine (transdermal), it is recommended to have a nitrate-free interval of at least 10-12 hours to prevent tolerance from developing. Tolerance can occur if the medication is continuously delivered without a break, leading to reduced effectiveness. Therefore, having a nitrate-free interval of 3-4 hours each day helps to maintain the efficacy of Nitroglycerine therapy and prevent tolerance.
Question 5 of 5
Jonas comes into the local blood donation center. He says he is here to donate platelets only today. The nurse knows this process is called:
Correct Answer: C
Rationale: Apheresis is the process of collecting specific blood components, such as platelets, using a specialized machine. This method allows the donor to donate only the needed component while returning the rest of the blood components back to the donor. In this case, when Jonas is donating platelets only, it is known as an apheresis donation. This process is different from the traditional whole blood donation method where all blood components are collected and separated later in a lab.
