After surgery, a post-operative patient has not urinated for 8 hours.
Where should the nurse check for bladder distention?

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.

Rationale for Choice A:
Sims' position is a side-lying position with the lower arm and leg flexed and the upper arm and leg extended. It is not ideal for bladder scanning because it can displace the bladder and potentially lead to inaccurate readings. While it can be used for other purposes, such as inserting rectal suppositories or performing vaginal exams, it's not the optimal choice for bladder scanning.
Rationale for Choice B:
Dorsal recumbent position is a supine position with the knees bent and feet flat on the bed. While it provides some exposure of the bladder, it may not fully visualize the entire bladder due to potential compression from the abdominal contents. This can also result in inaccurate readings.
Rationale for Choice D:
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 it can cause the bladder to shift upward and out of the optimal scanning range. It's typically used for respiratory comfort and procedures involving the head and upper body.
Rationale for Choice C:
Supine position is the best position for bladder scanning because it allows for the most accurate visualization of the bladder. In this position, the patient lies flat on their back with their legs extended. This position allows the bladder to rest naturally in the pelvic cavity, ensuring optimal positioning for the bladder scanner to capture a clear image and provide an accurate measurement of bladder volume. It also promotes patient comfort and relaxation during the procedure.
