A nurse is administering a 350 mL unit of PRBCs over 3 hours to a client diagnosed with anemia. The nurse should set the IV pump to deliver how many mL/hr?
The Correct Answer is ["2 "]
Step 1 is: To calculate the rate at which the IV pump should be set to deliver the PRBCs, we need to divide the total volume of PRBCs by the total time for administration.
Step 2 is: Convert the time for administration from hours to minutes because the rate is typically set in mL/min. So, 3 hours is equivalent to 180 minutes.
Step 3 is: Now, divide the total volume of PRBCs (350 mL) by the total time for administration (180 min). So, the calculation is 350 mL ÷ 180 min.
Step 4 is: The final calculated answer is approximately 1.94 mL/min. However, IV pumps typically only allow whole numbers, so we would round this to 2 mL/min.

Correct Answer is A
Explanation
Choice A rationale
Donepezil hydrochloride is a medication used to treat dementia related to Alzheimer’s disease. It works by improving mental function, such as memory and the ability to think and reason.
However, it is important to note that donepezil does not cure Alzheimer’s disease. The condition will worsen over time, even in people who take donepezil.
Choice B rationale
Donepezil does not limit the physical effects of Alzheimer’s disease and other dementias. While it can improve cognitive function, it does not directly impact the physical symptoms associated with these conditions.
Choice C rationale
Donepezil does not remove the patient’s insight that they have Alzheimer’s disease. It is a medication that helps to improve cognitive function, but it does not alter a person’s awareness or understanding of their condition.
Choice D rationale
Donepezil does not cure Alzheimer’s disease in any patients, let alone a small minority. It is a treatment that can help manage symptoms and improve cognitive function, but it does not stop the progression of the disease.
Correct Answer is A
Explanation
Choice A rationale
If a patient is suspected of having meningitis, the provider will likely prescribe antibiotic therapy after reviewing the lab results. Meningitis is often caused by a bacterial infection, and antibiotics are the primary treatment. The specific antibiotic prescribed will depend on the type of bacteria causing the infection.
Choice B rationale
Antiemetics are medications that help prevent and treat nausea and vomiting. They are not typically used as the primary treatment for meningitis.
Choice C rationale
Analgesics are medications that relieve pain. While they may be used to help manage symptoms in a patient with meningitis, they are not used to treat the underlying infection.
Choice D rationale
Antiviral therapy may be used if the meningitis is caused by a viral infection. However, most cases of meningitis are caused by bacteria, and antibiotics are the primary treatment.
