A nurse is planning care for a client who is to receive packed RBCs. The nurse should plan for the total infusion time to not exceed which of the following?
1 hour
2 hours
3 hours
4 hours
The Correct Answer is D
Choice A reason: Infusing packed RBCs over 1 hour is typically too rapid for most patients and can increase the risk of adverse reactions, especially in those with cardiovascular compromise.
Choice B reason: A 2hour infusion may be appropriate in certain emergency situations where rapid correction of anemia is required, but it is not the standard practice for routine transfusions.
Choice C reason: A 3hour infusion is less commonly used and does not provide any specific advantage over the standard 4hour infusion time.
Choice D reason: The standard practice is to complete the transfusion of packed RBCs within 4 hours. This duration minimizes the risk of bacterial growth and transfusion reactions, as recommended by the American Society of Hematology and other clinical guidelines.

Correct Answer is D
Explanation
Choice A reason: This choice is incorrect. A stroke involving the right cerebral hemisphere typically affects the left side of the body and can cause problems with spatial and perceptual abilities, not necessarily with language or discrimination of words and letters, which are more commonly associated with left hemisphere strokes⁸.
Choice B reason: Motor retardation is not specific to right hemisphere strokes. While right hemisphere strokes can cause weakness on the left side of the body, the term 'motor retardation' is not commonly used to describe this symptom⁸.
Choice C reason: This choice is incorrect because deficits in the right visual field would suggest a problem with the left cerebral hemisphere, not the right. A right hemisphere stroke typically causes problems with the left visual field⁸.
Choice D reason: This is the correct choice. Individuals with right hemisphere strokes may exhibit poor impulse control, as the right hemisphere is involved in judgment and behavior regulation⁸.
Correct Answer is A
Explanation
Choice A reason: This set of values is indicative of metabolic acidosis with respiratory compensation, which is common in chronic kidney disease due to the accumulation of acids in the blood and the lungs' attempt to compensate by retaining CO2.
Choice B reason: This choice suggests respiratory alkalosis, which is less likely in chronic kidney disease unless there is a secondary respiratory condition causing hyperventilation.
Choice C reason: This choice indicates metabolic alkalosis, which is not typical for chronic kidney disease, as the kidneys are unable to excrete acid effectively.
Choice D reason: While this set of values does indicate acidosis, the expected compensatory response in chronic kidney disease would be an elevated PaCO2, not a normal or low value.
