Uhhcs Urinary System (July) Quiz

A foley catheter is a type of urinary catheter that is used to empty the bladder. It is inserted into the bladder through the urethra and is secured in place by a balloon that is inflated with sterile water. The catheter allows urine to drain from the bladder into a collection bag, helping to relieve urinary retention or to monitor urine output. It is commonly used in medical settings, such as hospitals or nursing homes, for patients who are unable to urinate on their own or who require continuous bladder drainage.

The correct answer is to wipe down one side of the perineal area with the first towelette, down the other side with the second towelette, and down the middle with the third towelette. This is important for ensuring cleanliness and reducing the risk of contamination during the collection of a clean-catch midstream urine specimen. By wiping the perineal area in this manner, any potential bacteria or contaminants are removed, allowing for a more accurate urine sample.

Administering a 100 cc water flush and assessing for coughing is not a correct way to check the correct placement of a nasogastric tube. Coughing indicates that the tube may be in the respiratory tract rather than the gastrointestinal tract. Checking the pH of GI contents, obtaining a sample of GI contents through aspiration, and following the MD order for an X-ray are all appropriate methods to confirm the correct placement of the tube.

A random urine specimen is the most common type of urine sample as it can be taken at any time of the day without any specific timing requirements. It is convenient and does not require any special preparation or timing instructions. This type of sample is often used for routine testing and screening purposes.

Residual urine refers to the urine that remains in the bladder after a person has emptied their bladder through urination. This measurement is important in diagnosing bladder dysfunction or urinary retention. It is not related to leakage of urine or the collection of urine over a 24-hour period.

Supplementing oxygen using an adult non-rebreather mask is not a step that would be taken while replacing the tracheostomy tube. The focus should be on securing the new tube and ensuring proper placement, rather than providing supplemental oxygen.

A straight catheter is used to collect specimens or to instill medications. This type of catheter has a straight shape, allowing for easy insertion into the urethra. It is commonly used in medical procedures to collect urine samples or to administer medications directly into the bladder. The straight design of the catheter allows for efficient and effective collection or instillation of substances.

A clean catch midstream urine specimen is obtained by the patient after cleaning the genital area and then collecting a sample midstream during urination. This method helps to minimize contamination from the external genitalia and provides a more accurate representation of the patient's urine. It is commonly used for routine urinalysis and urine culture testing.

After obtaining a residual volume of 95 ml, the next nursing intervention would be to wait 30 minutes and reassess the residual after. This is because a residual volume of 95 ml indicates that there is a significant amount of food remaining in the stomach, which may increase the risk of aspiration if the feeding is administered immediately. Waiting and reassessing the residual after 30 minutes allows for more accurate determination of gastric emptying and helps in deciding whether to proceed with the feeding or not.

When collecting a 24-hour urine specimen, it is important to keep the specimen covered and in the refrigerator throughout the test. This is necessary to prevent the growth of bacteria or the breakdown of certain substances in the urine that could affect the accuracy of the test results. Refrigeration helps to maintain the stability of the urine specimen until it can be properly analyzed in the laboratory.
