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.

Explanation
Choice A rationale
While hypertension is a risk factor for stroke, it is a modifiable risk factor. This means it can be controlled and managed through lifestyle changes and medication.
Choice B rationale
Family history is a non-modifiable risk factor for stroke. If a close family member, like a parent or sibling, has had a stroke, a person’s risk of stroke is slightly higher.
Choice C rationale
Smoking is a modifiable risk factor for stroke. Quitting smoking can significantly reduce the risk of stroke.
Choice D rationale
Obesity is a modifiable risk factor for stroke. Maintaining a healthy weight through diet and regular exercise can help reduce the risk of stroke.
Correct Answer is A
Explanation
Choice A rationale
For a client with Parkinson’s disease who has difficulty swallowing or chewing due to muscle rigidity, semi-solid food with thick liquids can be easier to swallow and reduce the risk of choking19.
Choice B rationale
Minced foods and fluid restriction may not provide the necessary nutrients and hydration for a client with Parkinson’s disease19.
Choice C rationale
A low-residue diet, which is low in fiber, may not be appropriate for a client with Parkinson’s disease, as constipation is a common symptom of the disease and fiber can help alleviate this19.
Choice D rationale
Total parenteral nutrition (TPN) is a method of feeding that bypasses the gastrointestinal tract. It is typically reserved for clients who cannot or should not get their nutrition through eating19.
