Question 1 of 5
A nurse is working with a patient who is taking an adrenergic blocking agent. While assessing the patient’s medication history, the nurse discovers that the patient takes several alternative therapies. What herb is the nurse concerned may interact with the adrenergic blocking agent and affect the patient’s blood glucose level?
Correct Answer: C
Rationale: Di huang is an alternative therapy that can lower blood glucose when used in combination with adrenergic blocking agents. Ginseng increases antihypertensive effects; nightshade slows the heart rate; and saw palmetto increases the risk of urinary tract complications when used in combination with adrenergic blocking agents. The nurse should educate the patient about potential interactions and monitor blood glucose levels closely.
Question 2 of 5
What is the expected outcome for Valproate?
Correct Answer: D
Rationale: Valproate is an anticonvulsant medication commonly used to treat seizure disorders such as epilepsy. It works by stabilizing electrical activity in the brain, which helps to reduce the occurrence of seizures. Therefore, the expected outcome of Valproate treatment is a decrease in seizure activity and an improvement in seizure control.
Question 3 of 5
A male patient needs to receive a unit of whole blood. What type of intravenous (IV) device should the nurse consider starting?
Correct Answer: C
Rationale: A large-bore catheter is recommended for whole blood transfusions to allow for the rapid administration of blood products and to prevent hemolysis. Smaller catheters may not accommodate the viscosity of whole blood and could increase the risk of complications. While patient comfort and past experiences are important, the primary consideration is the safe and effective delivery of the transfusion. Therefore, a large-bore catheter is the best choice.
Question 4 of 5
Some institutions will not infuse a fat emulsion, such as Intralipid, into central venous access devices
Correct Answer: B
Rationale: Some institutions will not infuse a fat emulsion, such as Intralipid, into central venous access devices because lipid residue may accumulate in the CVAD and occlude the catheter. This can lead to complications such as catheter blockage, which may require removal and replacement of the catheter. The build-up of lipids in the catheter can interfere with proper medication delivery and potentially result in infection or other issues. Therefore, to prevent these complications, some institutions choose to avoid infusing fat emulsions through central venous access devices.
Question 5 of 5
A patient tells the nurse that he likes to eat large amounts of garlic to help lower his cholesterol levels naturally. The nurse reviews his medication history and notes that which drug has a potential interaction with the garlic?
Correct Answer: B
Rationale: Garlic is known to have antiplatelet and anticoagulant properties. When taken in large amounts, garlic can enhance the effects of anticoagulant medications like warfarin (Coumadin), which can increase the risk of bleeding. Therefore, it is crucial for patients on warfarin therapy to avoid consuming excessive amounts of garlic or garlic supplements to prevent potential interactions and complications.
