A nurse is performing a vision screening for a client. Which of the following findings should the nurse identify as an indication that the client has cataract?
Report of a chronic dull ache in the eyes
Bilateral redness of the sclerae
Increased opacity of the lens of the eye
Report of seeing halos around lights
The Correct Answer is C
A. Report of a chronic dull ache in the eyes: Eye discomfort or ache is more commonly associated with conditions like glaucoma or eye strain. Cataracts are typically painless and do not produce chronic dull ache.
B. Bilateral redness of the sclerae: Redness of the sclera indicates inflammation or infection, such as conjunctivitis, and is not a characteristic sign of cataracts.
C. Increased opacity of the lens of the eye: Cataracts are defined by a clouding or opacity of the eye’s lens, which interferes with light transmission and vision. This physical change in the lens is the hallmark finding in cataract development.
D. Report of seeing halos around lights: Seeing halos is more commonly associated with glaucoma due to increased intraocular pressure, rather than cataracts. While cataracts may cause blurred or dim vision, halos are not the primary symptom.

Correct Answer is B
Explanation
A. Metoprolol: Metoprolol is a beta-blocker used for hypertension or cardiac conditions. While it may affect blood pressure during the procedure, it is generally safe to continue and does not pose an immediate risk for colonoscopy.
B. Clopidogrel: Clopidogrel is an antiplatelet medication that increases the risk of bleeding. Because colonoscopy may involve biopsies or polypectomy, taking clopidogrel prior to the procedure significantly raises the risk of hemorrhage, making it the priority to report to the provider.
C. Metformin: Metformin is used to manage diabetes. It may require temporary discontinuation around procedures requiring contrast dye due to risk of lactic acidosis, but for a standard colonoscopy without contrast, it is less urgent than clopidogrel.
D. Digoxin: Digoxin is used for heart failure or arrhythmias. While monitoring for cardiac effects is important, digoxin does not pose an immediate risk for bleeding during colonoscopy and is not the priority to report.
Correct Answer is C
Explanation
A. A client who has chronic obstructive pulmonary disease and needs guidance on incentive spirometry: Teaching and guiding a client on incentive spirometry is a nursing intervention that requires assessment, education, and evaluation. It cannot be delegated to assistive personnel.
B. A client who had a myocardial infarction 3 days ago and reports chest discomfort: Chest discomfort in a post-MI client is a high-priority, potentially life-threatening issue. Only a licensed nurse can assess, intervene, and notify the provider, so this task is not appropriate for delegation.
C. A client who had a stroke 2 days ago and needs help toileting: Assisting a client with toileting is a basic activity of daily living and falls within the scope of practice for assistive personnel. The nurse can delegate this task safely.
D. A client who has awoken following a bronchoscopy and requests a drink: Post-procedure assessment and evaluating readiness for oral intake requires nursing judgment to ensure airway safety. This cannot be delegated to assistive personnel.
