To test a client’s ability to read small print, a nurse in a clinic asks the client to hold a Jaeger chart and instructs her to do which of the following?
Cover one eye while reading the smallest print with the other
Hold the chart at arm’s length while reading the chart with one eye
Read the bottom line of the chart from right to left with both eyes
Read the smallest print on the chart that can easily be read with both eyes
The Correct Answer is D
The Jaeger chart is used to measure near visual acuity, such as the ability to read small print. The chart is typically held 14 inches (35 cm) from the eyes, and the client is asked to read the smallest line of print they can see clearly. Testing is done with both eyes open, unless monocular testing is required. This helps identify problems like presbyopia or other near vision deficits.
Rationale for correct answer:
4. Read the smallest print on the chart that can easily be read with both eyes: This is the proper use of the Jaeger chart to test near vision, as it assesses the ability to read fine print at a close distance.
Rationale for incorrect answers:
1. Cover one eye while reading the smallest print with the other: This technique is used for Snellen chart testing of distance vision, not near vision with a Jaeger chart.
2. Hold the chart at arm’s length while reading the chart with one eye: The chart should be held at 14 inches, not at arm’s length, and it is usually tested with both eyes.
3. Read the bottom line of the chart from right to left with both eyes: Reading right to left is not required, and clients should read the smallest print they can see, not specifically the bottom line.
Take home points
- Jaeger chart → used for near visual acuity testing.
- Chart is held 14 inches away, tested with both eyes open.
- Client reads the smallest print visible → detects presbyopia or near vision deficits.

Correct Answer is B
Explanation
A cataract is the clouding of the eye’s natural lens, leading to blurred or hazy vision. Clients often describe vision as foggy, cloudy, or like looking through a film. If a client with a history of cataracts reports blurred or cloudy images again, this indicates a recurrence or progression.
Rationale for correct answer:
2. The client reports that the visual image is blurred or cloudy: This is the classic symptom of cataracts, as the lens becomes opaque and prevents clear light refraction.
Rationale for incorrect answers:
1. The client notices definite gaps in vision or blind spots: This is more characteristic of glaucoma or retinal detachment, not cataracts.
3. Tears flow incessantly throughout the examination: Excessive tearing is usually associated with eye irritation, conjunctivitis, or allergies, not cataracts.
4. The client’s eyes are red and swollen: Redness and swelling are signs of infection or inflammation, not cataracts, which are typically painless.
Take home points
- Cataracts cause blurred/cloudy vision—the most reliable symptom.
- No pain, redness, or tearing with cataracts—these suggest other eye problems.
- Gap in vision = glaucoma/retinal issue, not cataracts.
Correct Answer is B
Explanation
A detached retina is a serious ophthalmic emergency that requires surgery, such as scleral buckling, to reattach the retina and preserve vision. Postoperatively, vomiting can dramatically increase intraocular pressure, which may disrupt the surgical repair and cause recurrent detachment. Preventing complications from increased pressure is the nurse’s highest priority. Other issues like pain, anxiety, or boredom are important but do not threaten surgical success.
Rationale for correct answer:
2. Vomiting: Vomiting increases intraocular pressure, which can compromise the integrity of the retinal reattachment after scleral buckling, making it the highest priority problem.
Rationale for incorrect answers:
1. Pain: Pain should be managed, but it does not pose an immediate threat to the surgical outcome.
3. Anxiety: Anxiety is important to address but is not life-threatening postoperatively.
4. Boredom: Boredom is a minor concern and does not affect recovery or eye health.
Take home points
- Vomiting post-scleral buckling = highest priority due to risk of increased intraocular pressure.
- Pain and anxiety are secondary but should still be addressed.
- Monitor for signs of recurrent detachment and educate the patient to avoid straining, vomiting, or heavy lifting.
