A nurse is performing a complete physical examination on a patient. After examining the patient with the Snellen chart, the nurse documented distance vision in both eyes 20/40. The patient asks the nurse what 20/40 means:

(a) Inquire about family history of headaches:

While understanding the client's family history of headaches can be important for a comprehensive assessment, it is not the immediate priority. The description of "the worst headache" ever experienced could indicate a serious condition that needs urgent attention.

(b) Review the client's medical record:

Reviewing the client's medical record provides valuable information about their history and potential underlying conditions. However, given the severity of the reported headache, it is crucial to perform a more immediate physical assessment to rule out life-threatening conditions.

(c) Assess the client's blood pressure:

Assessing the client's blood pressure is a critical initial action. A severe headache can be a symptom of hypertensive crisis, stroke, or other serious conditions. High blood pressure could provide an immediate clue to the severity and cause of the headache, allowing for quicker intervention.

(d) Provide medication for pain relief:

Providing pain relief is important, but it should not be the first action without determining the cause of the headache. Administering medication without assessing the client's condition could mask symptoms of a potentially serious underlying issue such as a stroke or hypertensive emergency.

A) Assess the nasolacrimal sac: Excessive tearing, or epiphora, can result from an obstruction in the nasolacrimal duct, which drains tears from the eye into the nasal cavity. By assessing the nasolacrimal sac, the nurse can determine if there is any blockage or infection causing the excessive tearing, making this the most appropriate next step.

B) Test pupillary reaction to light: While testing pupillary reaction to light is important in a comprehensive eye exam, it does not directly address the issue of excessive tearing. This test is more focused on evaluating neurological function and overall eye health.

C) Inspect the palpebral conjunctiva: Inspecting the palpebral conjunctiva can help identify inflammation, infection, or foreign bodies that may cause discomfort or tearing. However, it does not specifically address the cause of excessive tearing related to nasolacrimal duct obstruction.

D) Perform the eye positions test: The eye positions test assesses extraocular muscle function and cranial nerve integrity. While it is important for a complete eye examination, it is not directly related to the symptom of excessive tearing, which is more likely due to issues with tear drainage.
