Explanation:

Question 1

In blood transfusion practice, one unit of red blood cells is typically transfused over 2 - 4 hours, with 2 hours being a common typical duration (80 minutes is too short, 5 hours is longer than typical, 4 hours is also common but 2 hours is a more typical stated duration in many protocols).

Patients are reassessed for transfusion reactions frequently during the process, and also at least with each set of vital signs. However, "frequently" is a more general and accurate description of the ongoing assessment, while "every 5 minutes" is too rigid (initial assessment is often every 15 minutes initially then less frequent, but overall it's frequent), "only at start and end" is incorrect, and "at least with each set of vital signs" is part of the frequent assessment. But the most accurate in terms of the process is that they are reassessed frequently.

In a suspected transfusion reaction, typically a blood sample (from the patient, and sometimes the remaining unit of blood) and sometimes a urine sample (to check for hemolysis) is collected. But if options were like blood sample, etc., the correct sample collection would involve blood (and possibly urine). Since the question is incomplete, but based on standard practice, in suspected transfusion reaction, blood samples (patient's post - transfusion, pre - transfusion if available, and the remaining blood product) are collected, and sometimes urine.
(Note: Since the question is cut off, this is a general explanation. If the options were provided, we could be more specific.)

Answer:

B. 2 hours
