A nurse is caring for a client who reports a decrease in central vision. The nurse should identify that this is a manifestation of which of the following visual impairments?
A. Macular degeneration
Reason: This is correct because macular degeneration is a condition that affects the macula, which is the central part of the retina that is responsible for sharp and detailed vision. Macular degeneration can cause blurred or distorted central vision, difficulty reading or recognizing faces, or dark spots in the visual field.
B. Glaucoma
Reason: This is incorrect because glaucoma is a condition that affects the optic nerve, which is the nerve that connects the eye to the brain and carries visual signals. Glaucoma can cause increased pressure inside the eye, damage to the optic nerve, and loss of peripheral vision.
C. Diabetic retinopathy
Reason: This is incorrect because diabetic retinopathy is a condition that affects the blood vessels in the retina, which is the layer of tissue at the back of the eye that converts light into nerve impulses. Diabetic retinopathy can cause bleeding, swelling, or leakage of fluid in the retina, and loss of vision in any part of the visual field.
D. Cataract
Reason: This is incorrect because cataract is a condition that affects the lens, which is the transparent structure behind the pupil that focuses light onto the retina. Cataract can cause clouding or opacity of the lens, and reduced vision in all parts of the visual field.

Full Explanation
Choice A Reason: This is correct because macular degeneration is a condition that affects the macula, which is the central part of the retina that is responsible for sharp and detailed vision. Macular degeneration can cause blurred or distorted central vision, difficulty reading or recognizing faces, or dark spots in the visual field.
Choice B Reason: This is incorrect because glaucoma is a condition that affects the optic nerve, which is the nerve that connects the eye to the brain and carries visual signals. Glaucoma can cause increased pressure inside the eye, damage to the optic nerve, and loss of peripheral vision.
Choice C Reason: This is incorrect because diabetic retinopathy is a condition that affects the blood vessels in the retina, which is the layer of tissue at the back of the eye that converts light into nerve impulses. Diabetic retinopathy can cause bleeding, swelling, or leakage of fluid in the retina, and loss of vision in any part of the visual field.

A nurse is caring for a client who has suffered a stroke involving the left hemisphere. Which of the following alterations in function are consistent with this type of stroke?
A. Slow cautious behaviors.
reason: This is incorrect because slow cautious behaviors are more consistent with a stroke involving the right hemisphere. The right hemisphere controls spatial awareness, creativity, and intuition. A stroke affecting this hemisphere can cause impulsivity, poor judgment, and denial of deficits.
B. Loss of depth perception.
reason: This is incorrect because loss of depth perception is more consistent with a stroke involving the right hemisphere. The right hemisphere controls visual-spatial perception, which includes depth perception, distance estimation, and object recognition. A stroke affecting this hemisphere can cause difficulty in navigating space, judging distances, and identifying objects.
C. Overestimation of abilities.
reason: This is incorrect because the overestimation of abilities is more consistent with a stroke involving the right hemisphere. The right hemisphere controls emotional regulation, self-awareness, and insight. A stroke affecting this hemisphere can cause euphoria, lack of insight, and unrealistic expectations.
D. Hemianopsia.
reason: This is the correct answer because hemianopsia is consistent with a stroke involving the left hemisphere. The left hemisphere controls language, logic, and analysis. A stroke affecting this hemisphere can cause hemianopsia, which is the loss of vision in half of the visual field. This can affect reading, writing, and communication skills.

A patient who is unconscious after a head injury has cerebral edema. Which nursing intervention will be included in the plan of care?
A. Encourage coughing and deep breathing
Reason: This is incorrect because encouraging coughing and deep breathing can increase intracranial pressure (ICP), which is the pressure inside the skull that can affect brain function. Coughing and deep breathing can increase blood flow and oxygen demand to the brain, which can worsen cerebral edema. The nurse should suction the patient as needed and maintain a patent airway.
B. Position the patient with knees and hips flexed
Reason: This is incorrect because positioning the patient with knees and hips flexed can increase ICP by reducing venous drainage from the head. The nurse should position the patient with neck and body in alignment and avoid extreme flexion or extension of any joints.
C. Perform nursing interventions once an hour to provide rest periods
Reason: This is incorrect because performing nursing interventions once an hour can disturb the patient's sleep and increase ICP by stimulating brain activity. The nurse should cluster nursing interventions and provide quiet and dark environment to promote rest and reduce stress.
D. Keep the head of the bed elevated to 30 degrees
Reason: This is correct because keeping the head of the bed elevated to 30 degrees can decrease ICP by facilitating venous drainage from the head and reducing cerebral blood volume. The nurse should monitor the patient's blood pressure and pulse to ensure adequate cerebral perfusion.

The nurse provides instructions to a client diagnosed with inflammatory bowel syndrome (IBS) about measures to treat diarrhea caused by acute flare-ups. Which statement by the client indicates a need for further teaching?
A. "I will eat frequent small meals."
Reason: This is correct because eating frequent small meals can help the client with IBS to avoid overloading the digestive system and triggering diarrhea. The nurse should advise the client to eat slowly and chew well, and avoid foods that are spicy, fatty, or gas-producing.
B. "I will increase the intake of leafy greens and other sources of dietary fiber."
Reason: This is incorrect because increasing the intake of leafy greens and other sources of dietary fiber can worsen diarrhea by increasing stool bulk and motility. The nurse should advise the client to limit or avoid high-fiber foods, such as whole grains, fruits, vegetables, nuts, and seeds, during acute flare-ups of IBS. The client can gradually reintroduce fiber when the symptoms subside.
C. "I will increase fluids."
Reason: This is correct because increasing fluids can help the client with IBS to prevent dehydration and electrolyte imbalance caused by diarrhea. The nurse should advise the client to drink at least 8 glasses of water per day and avoid caffeinated, alcoholic, or carbonated beverages that can irritate the bowel or cause gas.
D. "I will take prescribed medications on schedule to regulate bowel patterns."
Reason: This is correct because taking prescribed medications on schedule can help the client with IBS to regulate bowel patterns and reduce diarrhea. The nurse should instruct the client on how to use medications, such as antidiarrheals, antispasmodics, or probiotics, as ordered by the provider. The nurse should also monitor the client for any adverse effects or interactions of the medications.
