A nurse is reinforcing teaching with a client who is taking oxybutynin. The nurse should tell the client that the medication will have which of the following effects?
Relaxes the muscles of the bladder
Increases tissue perfusion in the lungs
Increases venous return to the heart
Relaxes the muscles of the colon
The Correct Answer is A
Choice A reason: Oxybutynin is an anticholinergic drug that relaxes the muscles of the bladder and reduces spasms, urgency, and frequency of urination. It is used to treat overactive bladder and urinary incontinence.
Choice B reason: Oxybutynin does not increase tissue perfusion in the lungs, as it has no effect on the respiratory system. It can actually cause dry mouth, nasal congestion, and blurred vision as side effects.
Choice C reason: Oxybutynin does not increase venous return to the heart, as it has no effect on the cardiovascular system. It can actually cause tachycardia, palpitations, and hypertension as side effects.
Choice D reason: Oxybutynin does not relax the muscles of the colon, as it has no effect on the gastrointestinal system. It can actually cause constipation, nausea, and abdominal pain as side effects.

Correct Answer is A
Explanation
Choice A reason: BUN or blood urea nitrogen 30 mg/dL is above the normal range of 10 to 20 mg/dL and indicates renal impairment or dehydration, which can be caused by contrast dye used during coronary angiography or blood loss during or after the procedure. The nurse should report this value to the provider and monitor the client for signs of acute kidney injury, such as oliguria, edema, or electrolyte imbalances.
Choice B reason: Sinus rhythm 95/min on a cardiac monitor is within the normal range of 60 to 100/min and does not indicate any cardiac arrhythmia or ischemia.
Choice C reason: Respiratory rate 12/min is within the normal range of 12 to 20/min and does not indicate any respiratory distress or hypoxia.
Choice D reason: PTT or partial thromboplastin time 25 seconds is within the normal range of 25 to 35 seconds and does not indicate any bleeding disorder or anticoagulant therapy.
Correct Answer is B
Explanation
Choice A reason: The thigh-high stockings should reach just below the gluteal folds, not above them. If the stockings are too high, they can cause constriction and impair circulation.
Choice B reason: Reapplying the stockings before getting out of bed is an appropriate action. The client should remove the stockings at night and inspect the skin for any signs of irritation or breakdown. The client should also elevate the legs for 15 minutes before putting on the stockings to reduce edema and improve venous return.
Choice C reason: Flexing the toes when applying the stockings is not an appropriate action. The client should point the toes and foot downward when applying the stockings to prevent wrinkles or folds that can cause pressure ulcers.
Choice D reason: Rolling down knee-high stockings slightly to provide comfort is not an appropriate action. The client should avoid rolling or folding the stockings as this can create a tourniquet effect and impair blood flow.
