The nurse is assessing the visual acuity of a client who reports changes in vision. How many feet away from the Snellen chart should the client stand? (Enter a whole number only.)

A. While notifying the healthcare provider is important if there are significant changes in the client's level of consciousness, it should not be the immediate next step. Before alerting the provider, the nurse needs to perform additional assessments to determine the extent of the client's unresponsiveness and gather more information about their neurological status.
B. Observing for eye opening in response to a painful stimulus is a critical step in assessing the depth of unconsciousness. This response helps determine the client's level of consciousness and can provide information about the severity of their condition.
C. Checking the pupillary response to light is important in evaluating neurological function and can provide information about brainstem activity and potential neurological deficits. However, it is secondary to checking for responses to stimuli like painful stimuli if the client is not opening their eyes spontaneously. Pupillary response should be assessed as part of a comprehensive neurological exam.
D. Asking the client to open his eyes might not be effective if the client is unresponsive or has impaired consciousness. If the client is not responding spontaneously, it is likely that verbal commands will also be ineffective. This step is less useful when assessing levels of consciousness compared to more objective assessments like responses to painful stimuli.

A. Nailbed clubbing is characterized by an increased angle between the nail and the nailbed, typically greater than 180 degrees. An angle of 200 degrees is consistent with clubbing, which can be a sign of chronic respiratory or cardiovascular conditions, such as chronic lung diseases, congenital heart defects, or other systemic conditions.
B. Consulting with a podiatrist to trim toenails is important for foot care but is not directly related to the finding of nailbed clubbing. The angle of the nailbed is more indicative of a systemic issue rather than a local foot care problem. Therefore, this action does not address the underlying concern suggested by the angle of 200 degrees.
C. While anemia or other blood conditions can affect the nails, the specific finding of a nailbed angle of 200 degrees is more indicative of clubbing rather than issues typically associated with hemoglobin levels. Therefore, while monitoring hemoglobin is important for overall health, it is not the immediate priority in response to the finding of nailbed clubbing.
D. Administering oxygen might be necessary if the client is experiencing symptoms of hypoxia or has a condition affecting oxygenation. However, the finding of nailbed clubbing itself does not immediately necessitate oxygen therapy. Oxygen administration should be based on specific symptoms or clinical indications of hypoxia rather than the nailbed angle alone.
