A nurse is assessing the visual acuity of a client who wears glasses using a Snellen chart. Which of the following actions should the nurse take?
Position the client 3 meters (10 feet) away from the chart
Document the largest line the client can read on the chart
Instruct the client to begin the assessment with both eyes open
Begin by testing the client while they are wearing glasses
The Correct Answer is D
To test visual acuity using a Snellen chart, the nurse should have the patient wear glasses or contact lenses if they normally wear them . The patient should stand 20 feet from the chart . The nurse should tell the patient to first cover the right eye, then left eye, and lastly read the chart with both eyes .
The other options are not correct because:
a). The client should be positioned 20 feet away from the chart, not 3 meters (10 feet).
b) The nurse should document the smallest line the client can read accurately on the chart, not the largest line.
c) The nurse should instruct the client to begin the assessment by covering one eye and reading aloud the letters on the chart, beginning at the top and moving toward the bottom

b. Platelet count 90,000/mm3.
Explanation:
During pregnancy, it is important to monitor the client's platelet count because a low platelet count can indicate a condition called gestational thrombocytopenia or other potential complications such as preeclampsia or HELLP syndrome. A platelet count of 90,000/mm3 is lower than the normal range and should be reported to the provider for further evaluation and management.
Option a, Hgb 12 g/dL, falls within the normal range for hemoglobin during pregnancy, which is typically between 11-13.5 g/dL. Therefore, it does not require immediate notification to the provider.
Option c, Hematocrit 37%, also falls within the normal range for hematocrit during pregnancy, which is typically between 33-42%. Therefore, it does not require immediate notification to the provider.
Option d, Creatinine 0.7 mg/dL, is within the normal range for creatinine levels and does not indicate any immediate concerns or need for notification to the provider.
It is important to remember that the interpretation of laboratory results should be done in the context of the client's individual clinical presentation and the healthcare provider's assessment. Any concerns or abnormal findings should be communicated to the provider for further evaluation and appropriate management.
