The nurse is preparing to assess a client's near vision. The nurse would use which piece of equipment for the assessment?

Snellen chart

Penlight

Magazine

Ophthalmoscope

Answer and Explanation

The Correct Answer is C

A) Snellen chart:

The Snellen chart is used to assess distance vision, not near vision. It consists of letters or symbols arranged in rows, with the client typically asked to read from a specific distance to test visual acuity.

B) Penlight:

A penlight is primarily used to assess pupillary reactions and near vision tasks such as accommodation. It helps examine how the pupils respond to light and how well the eyes focus on near objects.

C) Magazine:

A magazine or similar reading material is commonly used to assess near vision. Clients are asked to read the text at a comfortable distance, evaluating their ability to focus on close-up objects and the clarity of their vision.

D) Ophthalmoscope:

An ophthalmoscope is used to examine the interior structures of the eye, such as the retina and optic nerve head. It is not used for assessing near vision but rather for diagnosing conditions affecting the eye's internal structures.

Correct Answer is A

Explanation

(a) "Your metabolism is slowing down.":

Hypothyroidism leads to a decrease in the production of thyroid hormones, which are critical in regulating metabolism. With lower levels of these hormones, the body's metabolic rate decreases, resulting in reduced calorie burning and subsequent weight gain. This explanation directly addresses the underlying cause of weight gain in hypothyroidism.

(b) "You should be exercising for longer periods of time.":

While exercise is beneficial for overall health and can help manage weight, it does not directly address the reason for weight gain in hypothyroidism. The primary issue is the slowed metabolism due to thyroid hormone deficiency, not a lack of exercise.

Although diet plays a role in weight management, this response does not explain the root cause of weight gain in hypothyroidism. The condition itself slows metabolism, leading to weight gain even if dietary habits remain unchanged.

(d) "You are retaining fluid.":

Fluid retention can occur in hypothyroidism but is not the primary reason for weight gain in this condition. The main cause is a decreased metabolic rate, which leads to the accumulation of body fat. Fluid retention might contribute to some weight gain, but it is not the best explanation in this context.

A. Dehydration B. Hypervolemia C. Properly Hydrated D. Infection

Correct Answer is A

Explanation

A) Dehydration:

When the skin remains tented and returns to its normal position slowly after being pinched, it indicates decreased skin turgor, which is a clinical sign of dehydration. Dehydration can occur due to fluid loss from sweating during vigorous physical activity like a beach tournament.

B) Hypervolemia:

Hypervolemia refers to excess fluid volume in the body, which would typically manifest with signs such as peripheral edema or jugular vein distention rather than decreased skin turgor.

C) Properly Hydrated:

Properly hydrated individuals would have normal skin turgor, where the skin returns promptly to its normal position after being pinched.

D) Infection:

Skin tenting is not a specific sign of infection. Infection would typically present with localized signs such as redness, warmth, swelling, and possibly systemic signs like fever.
