When patients have their IOP measured, it determines the eye's what?

Ability to contract and relax the dilator muscle

Resistance from the ciliary bodies

Amount of aqueous humor

Tear duct capacity

Answer and Explanation

The Correct Answer is C

a) Ability to contract and relax the dilator muscle: This refers to the iris muscles, but it does not relate directly to the measurement of intraocular pressure (IOP).
b) Resistance from the ciliary bodies: The ciliary body produces aqueous humor, but IOP measures the pressure exerted by the amount of aqueous humor, not resistance from the ciliary bodies.
c) Amount of aqueous humor: IOP is determined by the balance between the production and drainage of aqueous humor within the eye.
d) Tear duct capacity: Tear duct capacity relates to tear drainage, not intraocular pressure.

Correct Answer is A

Explanation

a) "I will bend at my knees if I need to pick something up off of the floor." This statement shows an understanding of the importance of avoiding bending over at the waist post-surgery, which can increase intraocular pressure and disrupt the healing process.
b) "I can begin lying on my operative side 24 hours after my surgical procedure." Lying on the operative side should be avoided to prevent pressure on the healing eye.
c) "I will take a dose of aspirin if I have pain in the area of my eyebrow." Aspirin should generally be avoided after cataract surgery due to its anticoagulant effects, which may increase the risk of bleeding.
d) "I can pick up a sack of groceries that weighs 15 pounds." Lifting heavy objects is discouraged after cataract surgery to avoid putting pressure on the eye and affecting healing.

A. Take the client's temperature. B. Place a dressing under the client's nose. C. Test the drainage for glucose. D. Notify the charge nurse.

Correct Answer is C

Explanation

a) Take the client's temperature: This action is important but not the first priority. The nurse should first assess the nature of the drainage to determine whether it is cerebrospinal fluid (CSF).
b) Place a dressing under the client's nose: This action is also important to manage the drainage but does not address the need to determine the source of the drainage.
c) Test the drainage for glucose: The presence of glucose in the drainage is a key indicator that it is CSF. CSF typically contains glucose, and this test will help confirm whether the drainage is cerebrospinal fluid, which could indicate a serious complication like a CSF leak from a basal skull fracture.
d) Notify the charge nurse: While notifying the charge nurse is important, the first action is to test the drainage for glucose to determine its nature and assess the potential risks.
