A cleansing enema has been prescribed for a patient before his scheduled colon surgery. What is the reason for this procedure?
A. A cleansing enema is ordered because gastrointestinal peristalsis does not resume until 12 to 24 hours after surgery.
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
B. Cleansing enemas are administered prior to surgery only at the patient’s request.
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.
C. There will be less gas and discomfort post-operatively.
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.
D. Patients undergoing surgery are routinely given multiple pre-operative cleansing enemas.
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.

Similar Questions
Which of the following statements accurately describes the term “micturition”?
A. The act of experiencing total urinary incontinence.
Total urinary incontinence is the involuntary loss of all urine from the bladder. It is not synonymous with micturition, which is a controlled process of bladder emptying. Incontinence can stem from various factors, including neurological disorders, muscle weakness, medication side effects, and structural abnormalities. It's essential to distinguish between incontinence and micturition for accurate diagnosis and treatment.
B. The act of emptying the urinary bladder.
Micturition, also known as urination or voiding, is the physiological process of emptying the urinary bladder. It involves a coordinated interplay between the nervous system, bladder muscles, and urethral sphincters. When the bladder fills with urine, stretch receptors signal the nervous system, prompting the urge to urinate. If conditions are appropriate, the nervous system initiates a series of events: The detrusor muscle in the bladder wall contracts. The internal urethral sphincter relaxes, opening the pathway for urine to flow. The external urethral sphincter, under voluntary control, relaxes to allow urine to pass through the urethra and out of the body.
C. The condition of being unable to completely empty the urinary bladder.
The inability to completely empty the bladder is called urinary retention. It can result from various causes, including obstruction (e.g., enlarged prostate, urethral stricture), neurological disorders, medications, and pelvic floor dysfunction. Urinary retention differs from micturition, as it involves incomplete bladder emptying.
D. The act of catheterizing the urinary bladder.
Catheterization is the process of inserting a thin, flexible tube (catheter) into the bladder to drain urine. It's a medical procedure performed for various reasons, such as urinary retention, bladder obstruction, or to collect urine samples. Catheterization is not a natural process of micturition, but a medical intervention.

An adult female patient has been prescribed a 10-day course of nitrofurantoin (Macrodantin) for a urinary tract infection (UTI). On the sixth day, she contacts the healthcare provider’s office and informs the nurse that her symptoms have subsided. She inquires if she should continue with the treatment.
What would be the most suitable response from the registered nurse?
A. The treatment might have been successful, but we need to conduct another urinalysis to confirm.
Rationale for Choice A: While it's true that a urinalysis can confirm the eradication of bacteria, it's not routinely recommended in uncomplicated UTIs when symptoms have resolved. Conducting a urinalysis at this point could potentially lead to unnecessary healthcare visits and costs. It's important to prioritize patient adherence to the full course of antibiotics, as this is the most effective way to prevent recurrence of infection.
B. The treatment has not been effective, but you must continue with the antibiotic.
Rationale for Choice B: This response is inaccurate and could discourage the patient from completing the treatment. It's essential for the nurse to convey that the treatment is likely working, even though the patient is feeling better. Reinforcing the importance of completing the full course of antibiotics is crucial for optimal outcomes.
C. The treatment has been successful, and you may stop taking the antibiotic.
Rationale for Choice C: Stopping the antibiotic prematurely, even if symptoms have improved, can lead to: Increased risk of recurrent UTI Development of antibiotic resistance Prolonged or more severe infections in the future Completing the full course of antibiotics ensures that all bacteria are eradicated, reducing the likelihood of these complications.
D. The treatment has been successful, but you must complete the full course of the antibiotic.
Rationale for Choice D: This response correctly emphasizes the importance of completing the full course of antibiotics, even when symptoms have resolved. It addresses the patient's concern while providing accurate and essential information. Key points to highlight in this response include: The need to eliminate all bacteria, including those that may not be causing active symptoms The prevention of antibiotic resistance The reduction of the risk of recurrent UTIs

The prescription is for Ampicillin 1.5 grams to be added to 100mL of Normal Saline, to be infused over 120 minutes. The Drop Factor is 60gtt/mL. The pharmacy has provided Ampicillin 500mg in a 10mL vial. Calculate the flow rate in gtt/min at which the IV fluid should flow.
(Consider the medication that must be added to the total volume of fluid)
A. 50gtt/min
B. 33gtt/min
C. 65gtt/min
The formula for calculating flow rate is: Flow rate (gtt/min) = (Total volume (mL) ÷ Time (min)) × Drop factor (gtt/mL) Plugging in the values: Flow rate (gtt/min) = (130 mL ÷ 120 min) × 60 gtt/mL Flow rate (gtt/min) = 65 gtt/min Step 3: Round the flow rate to the nearest whole number. The calculated flow rate is 65 gtt/min. Rounding to the nearest whole number gives a flow rate of 65 gtt/min.
D. 100gtt/min
Full Explanation
The formula for calculating flow rate is:
Flow rate (gtt/min) = (Total volume (mL) ÷ Time (min)) × Drop factor (gtt/mL)
Plugging in the values:
Flow rate (gtt/min) = (130 mL ÷ 120 min) × 60 gtt/mL
Flow rate (gtt/min) = 65 gtt/min
Step 3: Round the flow rate to the nearest whole number.
The calculated flow rate is 65 gtt/min. Rounding to the nearest whole number gives a flow rate of 65 gtt/min.
