A nurse is reinforcing teaching about a tonometry examination with a client who has manifestations of glaucoma. Which of the following statements should the nurse include in the teaching?
This test will measure the intraocular pressure of the eye.
Tonometry will allow inspection of the optic disc for signs of degeneration.
Tonometry is performed to evaluate peripheral vision.
This test will diagnose the type of your glaucoma.
The Correct Answer is A
Choice A Reason:
Tonometry is a diagnostic test that measures the intraocular pressure (IOP) inside the eye. This measurement is crucial for detecting and managing glaucoma, as elevated IOP is a significant risk factor for the disease. By measuring the pressure, healthcare providers can assess the risk of optic nerve damage and initiate appropriate treatments to prevent vision loss.
Choice B Reason:
Tonometry does not allow for the inspection of the optic disc for signs of degeneration. This function is typically performed using ophthalmoscopy or optical coherence tomography (OCT), which provide detailed images of the optic nerve and retina. These tests are essential for evaluating the structural damage caused by glaucoma but are not part of the tonometry procedure.
Choice C Reason:
Tonometry is not performed to evaluate peripheral vision. Peripheral vision is assessed using perimetry or visual field testing, which maps the field of vision and detects areas of vision loss. This test helps determine the extent of visual impairment caused by glaucoma but is separate from tonometry.
Choice D Reason:
Tonometry does not diagnose the type of glaucoma. While it measures intraocular pressure, diagnosing the specific type of glaucoma requires a comprehensive eye examination, including gonioscopy to examine the drainage angle of the eye and other tests to assess optic nerve health and visual field. Therefore, tonometry is just one component of the diagnostic process.

Correct Answer is B
Explanation
Choice A Reason:
Increased appetite is not typically associated with anemia. Anemia generally leads to symptoms related to decreased oxygen-carrying capacity of the blood, such as fatigue, weakness, and shortness of breath. Increased appetite is more commonly linked to other conditions, such as hyperthyroidism or certain metabolic disorders.
Choice B Reason:
Fatigue is a common and significant symptom of anemia. When hemoglobin levels are low, the body’s tissues do not receive adequate oxygen, leading to feelings of tiredness and exhaustion. This is because hemoglobin is responsible for transporting oxygen from the lungs to the rest of the body. In anemia, the reduced oxygen delivery results in decreased energy levels and persistent fatigue.
Choice C Reason:
Weight gain is not typically associated with anemia. In fact, some forms of anemia, such as those caused by chronic diseases or malnutrition, may lead to weight loss rather than gain. Weight gain can be associated with other health issues, such as hypothyroidism or fluid retention, but not directly with anemia.
Choice D Reason:
Hypertension is not a common manifestation of anemia. Anemia usually leads to symptoms like pallor, shortness of breath, and fatigue due to the reduced oxygen-carrying capacity of the blood. Hypertension, or high blood pressure, is more commonly associated with cardiovascular diseases, kidney disorders, or endocrine conditions.
Correct Answer is D
Explanation
Choice A Reason:
Starting the patient on a high-calcium diet is not the most appropriate initial intervention for multiple myeloma. Multiple myeloma often leads to hypercalcemia, a condition where calcium levels in the blood are abnormally high due to bone breakdown. Increasing calcium intake can exacerbate this condition, leading to further complications such as kidney stones and impaired kidney function. Therefore, this choice is not suitable for managing the patient’s immediate symptoms.
Choice B Reason:
Encouraging the patient to increase physical activity to build bone strength is beneficial in the long term but not the most appropriate initial intervention. While weight-bearing exercises can help strengthen bones, they should be introduced gradually and under medical supervision to avoid fractures and other injuries. The immediate priority is to manage the patient’s pain and fatigue effectively.
Choice C Reason:
Advising the patient to limit fluid intake to prevent kidney damage is not appropriate. In fact, adequate hydration is crucial for patients with multiple myeloma to help flush out toxins and prevent kidney damage. Limiting fluid intake can lead to dehydration and worsen kidney function, which is already at risk due to the disease.
Choice D Reason:
Administering prescribed analgesics and educating the patient about pain management strategies is the most appropriate initial intervention. Pain management is a critical aspect of care for multiple myeloma patients, as bone pain is a common and debilitating symptom. Effective pain management improves the patient’s quality of life and allows them to participate in other therapeutic activities. Education on pain management strategies, including the use of medications, physical therapy, and complementary therapies, empowers the patient to manage their symptoms effectively.
