Question 1 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.
Question 2 of 5
What route is Amlodipine taken?
Correct Answer: A
Rationale: Amlodipine is a medication that is taken orally, usually in the form of tablets. The abbreviation "PO" stands for per os, which means by mouth or orally. Amlodipine is widely prescribed to treat high blood pressure and certain types of chest pain. It works by relaxing the blood vessels, making it easier for the heart to pump blood. Taking amlodipine orally allows it to be absorbed through the digestive system and enter the bloodstream to exert its therapeutic effects.
Question 3 of 5
The apparent volume of distribution:
Correct Answer: A
Rationale: A high apparent volume of distribution indicates extensive tissue binding or fat solubility, often exceeding total body water or blood volume.
Question 4 of 5
The nurse is reviewing new medication orders for a patient who has an epidural catheter for pain relief. One of the orders is for enoxaparin (Lovenox), a low“molecular-weight heparin (LMWH). What is the nurse™s priority action?
Correct Answer: C
Rationale: The nurse's priority action in this situation is to contact the prescriber because LMWHs like enoxaparin should not be given to a patient with an epidural catheter due to the increased risk of bleeding. Giving LMWH to a patient with an epidural catheter can lead to epidural hematoma, a serious complication that can result in permanent paralysis. It is important to clarify this order with the prescriber to ensure patient safety and prevent potential harm.
Question 5 of 5
A patient who has been diagnosed with social anxiety disorder will begin taking venlafaxine(Effexor). The nurse who performs a medication and dietary history will be concerned about ingestion of which substance or drug?
Correct Answer: D
Rationale: St. John's wort is an herbal supplement that can interact with many medications, including venlafaxine (Effexor). When taken together, it can decrease the effectiveness of venlafaxine by increasing its metabolism, potentially leading to reduced therapeutic effects. This interaction can also increase the risk of side effects or adverse reactions. Therefore, the nurse should be concerned about the ingestion of St. John's wort when a patient is taking venlafaxine to ensure proper medication management and effectiveness. It is important for patients to inform healthcare providers about all supplements they are taking to prevent harmful interactions.
