A nurse is performing an eye examination on a client. Which of the following findings should indicate to the nurse that the client might have cataracts?

Loss of central vision

Increased intraocular pressure

Decrease in peripheral vision

A bluish-white colored pupil

Answer and Explanation

The Correct Answer is D

A. Loss of central vision: While loss of central vision can occur with various eye conditions, such as age-related macular degeneration, it is not specific to cataracts. Cataracts typically cause clouding of the lens, leading to blurred or dimmed vision rather than loss of central vision.
B. Increased intraocular pressure: Increased intraocular pressure is characteristic of conditions such as glaucoma, not cataracts. Cataracts involve clouding of the lens rather than elevated pressure within the eye.
C. Decrease in peripheral vision: Decreased peripheral vision is associated with conditions like retinitis pigmentosa or glaucoma but is not a typical finding in cataracts. Cataracts primarily affect visual acuity and clarity rather than peripheral vision.
D. A bluish-white colored pupil: A bluish-white appearance of the pupil, known as leukocoria or a white pupil reflex, can be indicative of cataracts. It occurs due to light scattering by the cloudy lens of the eye, resulting in an abnormal reflection from the pupil. This finding is characteristic of cataracts and warrants further evaluation by an ophthalmologist.

Correct Answer is D

Explanation

A. Changing the inner cannula on a tracheostomy: This procedure falls within the RN's scope of practice, as it involves basic tracheostomy care and maintenance, which nurses commonly perform.
B. Administering a platelet transfusion: Administering blood and blood products, including platelet transfusions, is within the RN's scope of practice, provided the nurse has appropriate training and competency.
C. Irrigation of an external ear canal: Irrigation of an external ear canal is a routine nursing procedure that falls within the RN's scope of practice, as long as it does not involve invasive procedures beyond irrigation.
D. Inserting a tunneled central venous catheter: Inserting tunneled central venous catheters is typically performed by advanced practice nurses or physicians with specific training and certification, such as nurse practitioners or interventional radiologists. This procedure is beyond the scope of practice for RNs and requires specialized skills and knowledge.

A. Activate the fire alarm system. B. Evacuate clients from the area. C. Obtain and use a fire extinguisher. D. Close the doors and windows on the unit.

Correct Answer is B

Explanation

Answer: B

Rationale:

A) Activate the fire alarm system:

While activating the fire alarm system is essential in alerting everyone to the fire, the immediate safety of the clients must be prioritized first. Ensuring clients are safe from potential harm should precede alerting others.

B) Evacuate clients from the area:

Evacuating clients from the area is the first priority as it directly ensures their safety. In the event of a fire, removing individuals from the source of danger is crucial to prevent injury or harm.

C) Obtain and use a fire extinguisher:

Using a fire extinguisher to put out the fire is important, but it should not be the first action. Ensuring clients are evacuated to safety must take precedence before attempting to control the fire.

D) Close the doors and windows on the unit:

Closing doors and windows can help contain the fire and smoke, but this should follow the evacuation of clients. The primary concern is to get clients to a safe area first before taking measures to contain the fire.
