A nurse in a provider’s office is talking with a patient who takes oxybutynin. The patient asks why he does not urinate as often.
Which of the following information should the nurse include about the action of oxybutynin?
The medication prevents the bladder muscles from involuntarily contracting.
The medication blocks the nervous system impulse to produce urine.
The medication reduces the rate at which the kidneys filter waste.
The medication decreases the sensitivity of the urethral sphincter.
The Correct Answer is A
Choice A rationale
Oxybutynin works by relaxing the muscles in the bladder. This helps decrease muscle spasms and improve the ability to control urination, thereby reducing the frequency of urination.
Therefore, this choice is correct.
Choice B rationale
Oxybutynin does not block the nervous system impulse to produce urine. It works primarily by relaxing the bladder muscles. Therefore, this choice is incorrect.
Choice C rationale
Oxybutynin does not reduce the rate at which the kidneys filter waste. Its primary action is on the bladder muscles. Therefore, this choice is incorrect.
Choice D rationale
Oxybutynin does not decrease the sensitivity of the urethral sphincter. Its main effect is to relax the bladder muscles. Therefore, this choice is incorrect.

Correct Answer is ["B","C","F"]
Explanation
Choice A rationale:
Initiate a second peripheral IV is generally done to ensure reliable access for medication or fluid administration, especially in situations where multiple interventions are required. However, based on the information provided, there is no immediate indication that a second IV is necessary. The client's symptoms are more focused on managing and monitoring the current situation rather than starting additional IV lines at this point.
Choice B rationale:
Apply oxygen is a recommended action despite the client’s oxygen saturation being 97% on room air. The presence of chest pain and anxiety could indicate that the client may benefit from supplemental oxygen to alleviate symptoms and ensure adequate oxygenation. Applying oxygen can help reduce the client's respiratory distress and improve comfort, especially when experiencing sharp chest pain and rapid, shallow breathing.
Choice C rationale:
Obtain vital signs every 5 minutes is crucial in monitoring the client’s condition closely. Given the client's symptoms of anxiety, chest pain, and abnormal respirations, frequent monitoring will help detect any changes or deterioration in the client’s status. Regular vital sign checks are essential to ensure timely intervention if the client’s condition worsens or if any new symptoms arise.
Choice D rationale:
Perform gastric lavage is not indicated based on the client's symptoms and the information provided. Gastric lavage is typically used in cases of poisoning or overdose, not for symptoms of chest pain and anxiety. Therefore, this action is not appropriate for the client's current presentation.
Choice E rationale:
Prepare to administer anticoagulants is a specific intervention often considered for conditions like suspected pulmonary embolism or myocardial infarction. However, without more information on the client’s cardiac status or specific diagnostic results indicating the need for anticoagulants, this action cannot be recommended solely based on the provided data.
Choice F rationale:
Place the client in high-Fowler’s position is beneficial for improving breathing and reducing the workload on the heart. This position helps in alleviating symptoms related to respiratory distress and can be particularly helpful for clients with chest pain and rapid, shallow respirations. It facilitates better lung expansion and improves oxygenation.
Correct Answer is C
Explanation
Choice A rationale
Storing extra blankets in a box on the steps is not a safe practice for a client who has just returned home after a total hip arthroplasty. This could increase the risk of falls, which is a major concern after hip surgery.
Choice B rationale
Keeping pot handles turned towards the edge of the stove is not a safe practice. It increases the risk of spills and burns. Pot handles should always be turned towards the back of the stove to prevent accidents.
Choice C rationale
Placing electrical cords against the wall is a safe practice. It reduces the risk of tripping over the cords, which is especially important for a client who is recovering from a total hip arthroplasty.
Choice D rationale
Placing a throw rug next to the bathtub is not a safe practice. Throw rugs can easily slip and cause falls. A non-slip mat should be used instead.
