You are the student nurse teaching a patient about what foods to avoid prior to collection of a fecal occult blood test. The patient will need more education if the patient states:
I can eat 1-2 oranges
I will tell my wife that I cannot have grapefruit
I will not eat my raw vegetables for lunch
I will need to avoid lamb, beef, and pork
The Correct Answer is B
a) I can eat 1-2 oranges: Oranges are generally safe to eat prior to a fecal occult blood test. However, vitamin C-rich foods like citrus fruits should typically be avoided in large quantities before the test as they may interfere with the results. A small amount, such as 1-2 oranges, is acceptable.
b) I will tell my wife that I cannot have grapefruit: Grapefruit is rich in vitamin C, and high levels of vitamin C can interfere with the accuracy of the fecal occult blood test. This statement suggests a misunderstanding of which foods to avoid.
c) I will not eat my raw vegetables for lunch: Raw vegetables, particularly cruciferous ones like broccoli and cauliflower, are generally recommended to avoid prior to the test as they can cause false positives. The patient is correct in avoiding them.
d) I will need to avoid lamb, beef, and pork: Red meats like lamb, beef, and pork should be avoided before the test as they can cause false positives. The patient is correct in avoiding these meats.

Correct Answer is ["150"]
Explanation
To determine the infusion rate in mL/hr, divide the total volume (75 mL) by the time in hours (0.5 hours, since 30 minutes is 0.5 hours).
Rate(mL/hr)
= 75 ÷0.5
=150mL/hr
Correct Answer is D
Explanation
a) Kinking the catheter tubing to obtain a urine specimen: Kinking the catheter tubing can cause backflow of urine, increasing the risk of infection, but it is not as significant a risk factor as improper drainage bag positioning.
b) Emptying the drainage bag every 8 hours or when half full: Properly emptying the drainage bag regularly reduces the risk of infection, as it prevents overfilling and backflow. This practice is usually part of proper care.
c) Failing to secure the catheter tubing to the patient's thigh: Securing the tubing to the thigh is important for preventing pulling or tension, but it’s not as significant in terms of infection risk as the positioning of the drainage bag.
d) Placing the drainage bag on the side rail of the patient's bed: This significantly increases the risk of urinary tract infections (UTIs) as it can cause the urine to flow back into the bladder, a condition called "reflux." The drainage bag should always be kept below the level of the bladder.
