A nurse is preparing to administer 40 mg of furosemide intravenously.

The available furosemide is 10 mg/1 mL. How many mL should the nurse administer per dose? Round the answer to the nearest whole number.

Use a leading zero if it applies. Do not use a trailing zero.

Choice A rationale
Supporting the right arm with a sling or pillow can help prevent shoulder dislocation, but it may not directly ensure the safety of a patient who has experienced a stroke in the right hemisphere of the brain.
Choice B rationale
While it is true that a patient who has experienced a stroke in the right hemisphere of the brain may exhibit some degree of expressive or receptive aphasia, anticipating this does not directly ensure the patient’s safety.
Choice C rationale

Placing the wheelchair on the client’s left side when transferring him into a wheelchair is a good practice, but it may not directly ensure the safety of a patient who has experienced a stroke in the right hemisphere of the brain.
Choice D rationale
Patients who have experienced a stroke in the right hemisphere of the brain often exhibit impulsiveness and poor judgment. Therefore, providing close supervision can help ensure the patient’s safety.

Choice A rationale
Sensorineural hearing loss is a type of hearing loss in which the root cause lies in the inner ear or sensory organ (cochlea and associated structures) or the vestibulocochlear nerve (cranial nerve VIII). Sensorineural hearing loss can be mild, moderate, severe, or profound, and it affects the ability to hear faint sounds or understand speech. However, in the Rinne test, if the air-conducted sound is louder than the bone-conducted sound, it indicates that the patient’s hearing is likely normal.
Choice B rationale
Tinnitus is the perception of noise or ringing in the ears. It is a common problem that affects about 15 to 20 percent of people and is especially common in older adults. However, the Rinne test is not used to diagnose tinnitus. It is used to compare air and bone conduction of sound.
Choice C rationale
In a normal Rinne test, air conduction (AC) is better than bone conduction (BC). This is referred to as a positive Rinne test. If a patient reports that air-conducted sound is louder than bone-conducted sound, it suggests that the patient’s hearing is likely normal.
Choice D rationale
Otosclerosis is a condition that affects the bones in the middle ear, causing hearing loss. It is a common cause of conductive hearing loss, particularly in young adults. However, in otosclerosis, bone conduction (BC) is better than air conduction (AC), which is referred to as a negative Rinne test.
