The order is Ampicillin 1.5 grams added to 100mL of Normal Saline, infuse over 120 minutes. Drop Factor is 60gtt/mL. Available from pharmacy is Ampicillin 500mg in 10mL vial. Calculate the flow rate in gtt/min in which the IV fluid is to flow.
The Correct Answer is ["65"]
Here are the steps to calculate the flow rate in gtt/min:
Step 1: Calculate the total volume of fluid to be infused.
The order is for 1.5 grams of Ampicillin added to 100 mL of Normal Saline, so the total volume is 100 mL. Step 2: Calculate the number of vials of Ampicillin needed.
Each vial contains 500 mg of Ampicillin, and the order is for 1.5 grams (which is 1500 mg). Therefore, you will need 3 vials of Ampicillin (1500 mg ÷ 500 mg/vial = 3 vials). Step 3: Calculate the total volume of Ampicillin solution.
Each vial contains 10 mL of Ampicillin solution, and you need 3 vials.
Therefore, the total volume of Ampicillin solution is 30 mL (3 vials × 10 mL/vial = 30 mL). Step 4: Calculate the total volume to be infused, including the Ampicillin solution. The total volume is 100 mL of Normal Saline + 30 mL of Ampicillin solution = 130 mL. Step 5: Calculate the infusion time in minutes.
The order is to infuse over 120 minutes.
Step 6: Calculate the flow rate in gtt/min.
Use the formula: Flow rate (gtt/min) = Total volume (mL) × Drop factor (gtt/mL) ÷ Infusion time (min) Plug in the values: Flow rate = 130 mL × 60 gtt/mL ÷ 120 min
Simplify: Flow rate = 7800 ÷ 120
Flow rate = 65 gtt/min
Therefore, the flow rate in gtt/min in which the IV fluid is to flow is 65 gtt/min.

Correct Answer is D
Explanation
Choice A rationale:
Straight catheters are single-use catheters that are inserted into the bladder to drain urine and then immediately removed. They are not suitable for long-term use in clients with obstructed urethras because they would need to be inserted repeatedly, causing discomfort and potential trauma to the urethral tissues. Additionally, the obstruction itself would make it difficult or impossible to insert a straight catheter.
Choice B rationale:
Indwelling urethral catheters, also known as Foley catheters, are inserted into the bladder and remain in place for a period of time. They are typically used for clients who cannot void on their own or who require continuous bladder drainage. However, they are not the best option for clients with obstructed urethras for the following reasons:
The presence of the catheter within the urethra can further irritate or damage the already obstructed tissues. The balloon that holds the catheter in place could potentially worsen the obstruction.
The risk of urinary tract infections (UTIs) is increased with indwelling catheters.
Choice C rationale:
Intermittent urethral catheters are inserted into the bladder to drain urine and then removed. They are typically used by clients who can self-catheterize several times a day. However, they are not suitable for clients with complete prostatic obstruction, as the obstruction would make it difficult or impossible to insert the catheter.
Choice D rationale:
Suprapubic catheters are inserted directly into the bladder through a small incision in the abdomen, bypassing the urethra entirely. This makes them the most suitable option for clients with obstructed urethras, as it eliminates the need to pass a catheter through the obstructed area. Suprapubic catheters offer several advantages in this situation:
They avoid further irritation or damage to the urethral tissues.
They provide a more comfortable and convenient option for long-term bladder drainage.
They may reduce the risk of UTIs compared to indwelling urethral catheters.
Correct Answer is A
Explanation
Choice A rationale:
Impaired cognitive and motor function:
Anesthesia and analgesic medications used during surgery can significantly impair cognitive and motor skills, even if the patient feels alert and capable. These effects can last for several hours or even days after the procedure, making it unsafe for the patient to drive.
Studies have shown that reaction time, judgment, coordination, and visual acuity can be significantly impaired following surgery, even in patients who report feeling normal.
Driving under the influence of these medications poses a serious risk of accidents and injuries, both to the patient and other road users.
Risk of postoperative complications:
Postoperative complications, such as bleeding, nausea, vomiting, pain, or dizziness, can occur unexpectedly and may require immediate attention.
Driving while experiencing these complications can be extremely dangerous and could delay necessary medical intervention.
It's crucial for the patient to have a responsible adult present to monitor their condition and seek medical assistance if needed. Legal and liability considerations:
Many healthcare facilities have strict policies prohibiting patients from driving after surgery due to liability concerns.
If a patient were to be involved in an accident while driving after surgery, the facility could be held liable for not ensuring the patient's safety and preventing them from driving.
Choice B rationale:
Inadequate guidance: Simply stating that no specific information is necessary fails to address the potential risks associated with driving after surgery.
Patient safety: It's the nurse's responsibility to provide clear and comprehensive discharge instructions that prioritize patient safety.
Omission of crucial information: Omitting information about transportation could lead to misunderstandings and potentially unsafe actions by the patient.
Choice C rationale:
Unreliable self-assessment: Relying on the patient's self-assessment of dizziness is not a reliable method to determine their fitness to drive.
Residual effects of medication: Patients may not fully perceive the subtle effects of anesthesia and medications on their cognitive and motor skills.
Potential for delayed impairment: Symptoms such as dizziness or drowsiness could manifest later, even if the patient initially feels well.
Choice D rationale:
Age not a sole determinant: While age can be a factor in driving ability, it's not the sole determinant of fitness to drive after surgery.
Individual differences: Patients of any age can experience cognitive and motor impairment following surgery.
Oversimplification of risks: This choice inaccurately suggests that only individuals under 25 are at risk, potentially leading to unsafe decisions by older patients.
