The nurse working in an ophthalmology clinic is preparing to assess a patient's near vision. Which piece of equipment would the nurse use for this assessment?

Ophthalmoscope

Snellen Chart

Magazine

Penlight

Answer and Explanation

The Correct Answer is B

Choice A Reason:
An ophthalmoscope is primarily used for examining the interior structures of the eye, such as the retina, and is not typically used for assessing near vision. It provides a view of the fundus of the eye, which is essential for diagnosing various eye conditions but does not directly assess a patient's reading or close-up vision.

Choice B Reason:
The Snellen Chart is traditionally used to measure distance visual acuity and would not be the first choice for assessing near vision. However, there are versions of the Snellen Chart or similar charts designed for near vision assessment, typically held at a reading distance of about 14 inches from the patient. These charts have rows of letters or symbols that decrease in size and are used to determine the smallest print size a person can read.

Choice C Reason:
A magazine can be a practical tool for assessing near vision informally, as it contains various sizes of print and is a good representation of everyday reading material. The nurse can ask the patient to read a specific paragraph to observe their ability to see and comprehend text at a close distance.

Choice D Reason:
A penlight is not used for assessing near vision. It is typically used to assess the pupillary light reflex or to illuminate specific areas of the eye during an examination. The penlight helps to evaluate the response of the pupils to light but does not measure the patient's ability to read or see objects up close.

Correct Answer is B

Explanation

Choice A reason:
Facial expression is an important aspect of the general survey as it can provide clues about a patient's emotional state and possible pain. However, it is not directly related to the patient's level of consciousness. After a motor vehicle crash, assessing facial expression is crucial to identify any signs of distress, trauma, or neurological impairment.
Choice B reason:
Level of consciousness is a critical component of the general survey, especially in the context of trauma or potential neurological injury. It refers to the patient's awareness and responsiveness to the environment. Assessing the level of consciousness involves determining if the patient is awake, alert, and oriented to time, place, and person, which is essential for establishing a baseline cognitive function and detecting any changes that may indicate deterioration or improvement in their condition.
Choice C reason:
Posture, gait, motor activity, and speech are assessed to evaluate the musculoskeletal and neurological systems. While these are important in the context of a motor vehicle crash, they are not specifically related to the level of consciousness. These assessments help identify any deficits that may result from injuries sustained during the crash, such as fractures, dislocations, or neurological damage affecting movement and coordination.
Choice D reason:
The apparent state of health is a broad assessment that includes the patient's overall appearance and any signs that may indicate acute or chronic illness. In the emergency setting, this may involve observing for signs of trauma, shock, or other life-threatening conditions. While it is an essential part of the general survey, it is not specifically focused on the level of consciousness but rather on the patient's general well-being and any obvious health concerns.

A. "I should get a longer cord for my telephone." B. "I should place a throw rug over electrical cords." C. "It is a good idea to use the handrails in the bathroom." D. "I should use chairs without armrests."

Correct Answer is C

Explanation

Choice a reason:
Getting a longer cord for the telephone may reduce the risk of tripping over a short cord but could potentially introduce new tripping hazards if not managed properly. It's important to keep cords secured and out of walkways to prevent falls.

Choice b reason:
Placing a throw rug over electrical cords is not advisable as it can create a tripping hazard. Rugs should be secured with non-slip backing and kept away from high-traffic areas to prevent falls.

Choice c reason:
Using handrails in the bathroom is a recommended safety measure to prevent falls. Bathrooms can be slippery, and handrails provide support and stability for residents when moving around in this area.

Choice d reason:
Using chairs without armrests is not a recommended practice for fall prevention. Chairs with armrests can aid residents in safely sitting down and standing up, providing support and reducing the risk of falls.
