The client inquires what the positive result from the potassium hydroxide (KOH) test indicates. Which of the following is an accurate response by the nurse?

You have a virus.

You have a fungal infection.

You have a bacterial infection.

You have cancer.

Answer and Explanation

The Correct Answer is B

Choice A Reason: A virus is not detected by the KOH test, which is used to diagnose fungal infections of the skin, hair, or nails. A virus can be detected by other tests, such as polymerase chain reaction (PCR) or viral culture.

Choice B Reason: A fungal infection is detected by the KOH test, which dissolves the skin cells and leaves behind the fungal elements that can be seen under a microscope. A fungal infection can cause symptoms such as itching, scaling, redness, or blisters.

Choice C Reason: A bacterial infection is not detected by the KOH test, which is specific for fungi. A bacterial infection can be detected by other tests, such as gram stain or culture.

Choice D Reason: Cancer is not detected by the KOH test, which is not a screening tool for malignancy. Cancer can be detected by other tests, such as biopsy or imaging.

Correct Answer is B

Explanation

Choice A Reason: Hemorrhage is not a complication of an acute spinal cord injury, but rather a possible cause of it. Hemorrhage can occur due to trauma or rupture of blood vessels in or around the spinal cord, leading to compression and damage of the nerve tissue.

Choice B Reason: This is the correct choice. Spinal shock is a complication of an acute spinal cord injury that occurs within minutes to hours after the injury. It is characterized by loss of sensation, motor function, reflexes, and autonomic function below the level of injury. It is caused by transient disruption of nerve conduction and synaptic transmission in the spinal cord.

Choice C Reason: Apoptosis is not a complication of an acute spinal cord injury, but rather a cellular process that occurs after it. Apoptosis is programmed cell death that occurs in response to injury or stress. It can lead to further loss of neurons and glial cells in the spinal cord over time.

Choice D Reason: Neurogenic shock is a complication of an acute spinal cord injury that occurs within hours to days after the injury. It is characterized by hypotension, bradycardia, and peripheral vasodilation due to loss of sympathetic tone and unopposed parasympathetic activity. It is caused by disruption of autonomic pathways in the spinal cord.

A. The client needs total nursing care. B. Indicates stable neurologic status C. The client has a decline in level of consciousness but is able to protect his airway D. The client is alert and oriented.

Correct Answer is A

Explanation

Choice A Reason: 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.

Choice B Reason: 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.

Choice C Reason: 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.

Choice D Reason: 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.
