A cleansing enema has been prescribed for a patient before his scheduled colon surgery. What is the reason for this procedure?
A cleansing enema is ordered because gastrointestinal peristalsis does not resume until 12 to 24 hours after surgery.
Cleansing enemas are administered prior to surgery only at the patient’s request.
There will be less gas and discomfort post-operatively.
Patients undergoing surgery are routinely given multiple pre-operative cleansing enemas.
The Correct Answer is C
Choice A rationale:
While it's true that gastrointestinal peristalsis may be slowed after surgery, this is not the primary reason for administering a cleansing enema before colon surgery.
The main goal of the enema is to evacuate stool from the colon, ensuring a clear and unobstructed surgical field. This helps to:
Reduce the risk of infection
Facilitate better visualization of the colon during surgery
Minimize the potential for complications
Choice B rationale:
Cleansing enemas are not administered solely based on patient request.
They are prescribed for specific medical reasons, such as preparing for colon surgery or certain diagnostic procedures. Patient preference may be considered, but it's not the determining factor.
Choice C rationale:
While decreased gas and discomfort post-operatively can be a potential benefit of a cleansing enema, it's not the primary reason for its use before colon surgery.
The primary goal, as mentioned earlier, is to clear the colon for a safe and effective surgical procedure. However, reduced gas and discomfort can contribute to a smoother post-operative recovery.
Choice D rationale:
Multiple cleansing enemas are not routinely given to all surgical patients.
The decision to administer an enema is based on the specific type of surgery, the patient's condition, and other factors. In some cases, a single enema may be sufficient, while others may require more than one.

Correct Answer is B
Explanation
Choice A rationale:
Brown or black urine is not a typical observation associated with Levodopa use. It can indicate other potential causes, such as: Dehydration
Liver disease
Rhabdomyolysis (muscle breakdown)
Certain medications like metronidazole or iron supplements
Hematuria (blood in the urine)
It's essential to rule out these conditions if brown or black urine is observed.
Choice C rationale:
Green or blue-green urine is also not common with Levodopa. It can be caused by:
Medications like amitriptyline, indomethacin, propofol, or methylene blue
Certain food dyes
Urinary tract infections caused by Pseudomonas bacteria
Familial benign hypercalcemia (a rare genetic condition)
Choice D rationale:
Blood-tinged urine (hematuria) is not a direct effect of Levodopa. It can signal underlying urinary tract issues, such as: Infections
Kidney stones
Bladder or kidney tumors
Trauma to the urinary tract
Strenuous exercise
Choice B rationale:
Orange or orange-red urine is the most common observation in patients taking Levodopa. This discoloration is due to: Breakdown of Levodopa into dopamine and other metabolites
These metabolites can impart an orange or reddish hue to the urine
The color intensity may vary depending on dosage and individual metabolism
It's generally harmless and doesn't require medical intervention
However, it's essential to inform healthcare providers about any urine color changes to ensure proper monitoring and rule out other potential causes.
Correct Answer is B
Explanation
Choice A rationale:
Sims' position is a side-lying position with the lower leg flexed and the upper leg extended. It is not ideal for bladder scanning because it can compress the bladder and make it difficult to obtain an accurate reading.
Additionally, in Sims' position, the bladder may not be fully accessible to the scanner, as it may be partially obscured by the upper thigh.
Choice B rationale:
Dorsal recumbent position is the optimal position for bladder scanning. In this position, the client lies flat on their back with their knees bent and their feet flat on the bed. This position allows for:
Full exposure of the bladder, making it easily accessible to the scanner.
Relaxation of the abdominal muscles, which can help to ensure an accurate reading.
A comfortable position for the client, promoting cooperation and reducing the likelihood of movement that could interfere with the scan.
Choice C rationale:
Supine position is a similar position to dorsal recumbent, but with the legs fully extended. While it is possible to perform a bladder scan in this position, it is not as ideal as dorsal recumbent because:
The extended legs can place some tension on the abdominal muscles, potentially affecting bladder position and the scan's accuracy.
The client may find this position less comfortable, leading to restlessness and potential movement that could interfere with the scan.
Choice D rationale:
High Fowler's position is a semi-sitting position with the head of the bed elevated at a 45- to 60-degree angle. This position is not suitable for bladder scanning because:
Gravity can pull the bladder downwards, making it difficult to visualize and measure accurately.
It can be challenging to maintain proper positioning of the scanner on the abdomen in this position, potentially leading to inaccurate readings.
