Question 2 of 5
A nurse is assessing a client who has a score of 6 on the Glasgow Coma Scale. The nurse should expect which of the following outcomes based on this score?
Correct Answer: A
Rationale: The client needs total nursing care is the expected outcome for a client who has a score of 6 on the Glasgow Coma Scale, which is a tool that measures the level of consciousness based on eye opening, verbal response, and motor response. A score of 6 indicates severe brain injury and coma, meaning that the client is unresponsive and dependent on others for all activities of daily living. Indicates stable neurologic status is not the expected outcome for a client who has a score of 6 on the Glasgow Coma Scale, which indicates severe brain injury and coma. A stable neurologic status means that there are no changes in the level of consciousness, vital signs, or neurological signs. The client has a decline in level of consciousness but is able to protect his airway is not the expected outcome for a client who has a score of 6 on the Glasgow Coma Scale, which indicates severe brain injury and coma. A decline in level of consciousness means that the client is less alert and responsive than normal, but still able to respond to stimuli and maintain airway patency. The client is alert and oriented is not the expected outcome for a client who has a score of 6 on the Glasgow Coma Scale, which indicates severe brain injury and coma. Alert and oriented means that the client is fully awake and aware of person, place, time, and situation.

Question 5 of 5
The physician suspects a client has a dermatological infection. Which of the following diagnostics will be ordered to observe color changes to the skin using an ultraviolet light source?
Correct Answer: D
Rationale: Culture is not a diagnostic test that uses an ultraviolet light source, but a laboratory test that involves growing microorganisms from a sample of body fluid or tissue. Culture can help identify the type and sensitivity of the infection-causing agent. KOH is not a diagnostic test that uses an ultraviolet light source, but a chemical test that involves applying potassium hydroxide to a sample of skin, hair, or nail. KOH can help diagnose fungal infections by dissolving the keratin and revealing the fungal elements under a microscope. Diascopy is not a diagnostic test that uses an ultraviolet light source, but a physical test that involves applying pressure to a lesion with a glass slide or lens. Diascopy can help differentiate between blanchable and non-blanchable lesions, such as erythema or petechiae. Wood's is a diagnostic test that uses an ultraviolet light source, also known as a Wood's lamp or black light. Wood's can help observe color changes to the skin that are not visible under normal light, such as fluorescence or hypopigmentation. Wood's can help diagnose conditions such as tinea capitis, vitiligo, or erythrasma.
