A nurse is reinforcing teaching with a client who has primary open-angle glaucoma and a new prescription for timolol eye drops. Which of the following statements indicates an understanding of the teaching?
"I should take a zinc supplement while taking this medication."
"This medication will dilate my eyes."
"I should check my heart rate while taking this medication."
"This medication will darken the color of my eyes."
The Correct Answer is C
Timolol is a beta-blocker medication that is commonly prescribed for the treatment of glaucoma. It works by reducing the production of aqueous humor in the eye, thereby decreasing intraocular pressure. However, timolol can also be systemically absorbed, which may lead to cardiovascular side effects.
Checking the heart rate while taking timolol is important because beta-blockers can potentially lower heart rate and blood pressure. It is essential to monitor for any changes in heart rate or any other cardiovascular symptoms while using timolol eye drops.

Correct Answer is C
Explanation
A.Collecting a sterile specimen from the urinary drainage bag is incorrect because urine in the drainage bag is not considered sterile. If a sterile specimen is needed, it should be obtained by cleaning the catheter's sampling port with an antiseptic solution and withdrawing urine directly from the port using a sterile syringe.
B.Instructing the client to hold the drainage bag at waist height when ambulating is incorrect because the drainage bag should always be kept below the level of the bladder to prevent urine from flowing back into the bladder, which could lead to a urinary tract infection (UTI).
C.Securing the tubing with adhesive tape to the lower abdomen is correct because it helps prevent accidental pulling or tugging on the catheter, which could cause discomfort or dislodgement. Properly securing the tubing also helps maintain a continuous flow of urine and reduces the risk of infection.
D.Collecting a sterile specimen from the urinary drainage bag is incorrect because urine in the drainage bag is not considered sterile. If a sterile specimen is needed, it should be obtained by cleaning the catheter's sampling port with an antiseptic solution and withdrawing urine directly from the port using a sterile syringe..
Correct Answer is A
Explanation
a. Sounds are high-pitched.
Hyperactive bowel sounds are bowel sounds that are louder and more frequent than normal. They may be heard as high-pitched rushing or tinkling sounds that occur irregularly at a rate greater than 5-6 sounds per minute. They are often associated with increased intestinal motility, such as in diarrhea, gastroenteritis, or early bowel obstruction.
Option b is incorrect because hyperactive bowel sounds are not typically associated with a paralytic ileus, which is a condition where the bowel stops working and there is a lack of bowel sounds.
Option c is incorrect because hyperactive bowel sounds indicate increased motility, not decreased motility.
Option d is incorrect because soft bowel sounds at a rate of 1/min are considered hypoactive bowel sounds, which can be a sign of decreased intestinal motility, as seen in constipation or postoperative ileus.
