A patient is taking gentamicin (Garamycin) and furosemide (Lasix). The nurse should counsel this patient to report which symptom?
a. Frequent nocturia
b. Headaches
c. Ringing in the ears
d. Urinary retention
ANS: C
Patients taking furosemide should be advised that the risk of furosemide-induced hearing loss can be increased when other ototoxic drugs, such as gentamicin, are also taken. Patients should be told to report tinnitus or dizziness or hearing loss. Nocturia may be an expected effect of furosemide. Headaches are not likely to occur with concomitant use of gentamicin and furosemide. Urinary retention is not an expected side effect.

Bonnie is a 70-year-old woman who lives alone. One evening, she felt light-headed and dizzy. When her head began to ache, she decided to take an analgesic and go to bed early
The following morning, upon awakening, she was unable to move the bed sheets with her right arm. At this point she was experiencing tingling sensations in her limbs, and she had difficulty keeping her balance. She dialed 911 for help, and by the time the ambulance arrived, she was confused and unable to articulate her words although she knew what information he was asking of her. In the hospital, she was examined and treated for ischemic stroke. Stroke, or brain attack, involves brain tissue injury. Describe ischemic penumbra and what factors contribute to the survival of the neurons involved. What happens if the cells of the penumbra are unable to be preserved? Compare and contrast hypoxia and ischemia. What condition is more dangerous to the brain? Explain your answer.
