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

Correct Answer is A
Explanation
The initial diphtheria, tetanus, and pertussis (DTaP) vaccine is indicated for a 2-month-old infant. The DTaP vaccine is typically administered as a series of doses starting in infancy to provide protection against diphtheria, tetanus, and pertussis (whooping cough).
The recommended schedule for the DTaP vaccine includes a series of doses at 2, 4, and 6 months of age, with additional booster doses given later in childhood. Therefore, the first dose of DTaP is given to infants at 2 months of age.
The other options are incorrect because:
b) A 4-month-old infant: By 4 months of age, the second dose of the DTaP vaccine should be administered, not the initial dose.
c) A 6-month-old infant: By 6 months of age, the third dose of the DTaP vaccine should be administered, not the initial dose.
d) A 15-month-old toddler: By 15 months of age, the toddler would have already received multiple doses of the DTaP vaccine as part of the recommended series. The initial dose is typically given earlier, at 2 months of age.
Correct Answer is A
Explanation
a. "The machine is programmed to prevent you from administering more than a safe dose."
When reinforcing teaching about epidural PCA (patient-controlled analgesia) with a client in active labor, it is important for the nurse to inform the client about the safety features of the machine. By explaining that the machine is programmed to prevent the client from administering more than a safe dose, the nurse reassures the client that they have control over their pain relief while minimizing the risk of overdose.
Option b, "During medication administration, you will not be able to move your legs freely," is not an accurate statement regarding epidural PCA. While epidural analgesia may cause temporary weakness or loss of sensation in the lower body, the ability to move the legs freely is not necessarily completely impaired. The degree of mobility can vary depending on the dosage and specific characteristics of the epidural.
Option c, "This method of pain control will shorten the second stage of labor," is not a valid statement. Epidural PCA is primarily used for pain relief during labor and delivery but does not directly affect the progression or duration of the second stage of labor, which involves pushing and the delivery of the baby.
Option d, "This type of anesthesia commonly causes a postpartum headache," is also incorrect. While headaches can occur as a potential side effect of epidural anesthesia, they are not specifically associated with epidural PCA. Postpartum headaches can have various causes and are not exclusively related to the use of epidural PCA.
By emphasizing the safety features of the machine and explaining that it prevents the administration of excessive doses, the nurse ensures that the client understands the appropriate use of the epidural PCA for pain control during labor.
