Nursing Elites

1. A client is having difficulties reading an educational pamphlet. He cannot find his glasses. In order to read the words, he must hold the pamphlet at arm's length, which allows him to read the information. Which vision deficit does this client most likely suffer from?

• A. Cataracts
• B. Glaucoma
• C. Astigmatism
• D. Presbyopia

Correct answer: D

Rationale: Presbyopia is a condition that occurs when the lens of the eye loses accommodation and is unable to focus light on objects nearby. As a result, clients are unable to see or read items up close but may have success when holding the same item at arm's length. Many clients with presbyopia must wear bifocals, but long-distance vision remains unaffected. Cataracts involve clouding of the eye's lens, leading to blurry vision. Glaucoma is associated with increased intraocular pressure that damages the optic nerve, causing vision loss. Astigmatism is a refractive error where the cornea or lens has an irregular shape, leading to distorted or blurred vision.

2. What is the MOST ACCURATE statement regarding the ESR test?

• A. The results are diagnostic for certain conditions.
• B. Abnormal results are indicative of a potentially fatal illness.
• C. Abnormal results should be followed by additional testing.
• D. Results are reported in millimeters per hour.

Correct answer: C

Rationale: The erythrocyte sedimentation rate (ESR) is a non-specific screening test for inflammation in the body. It is not used as a definitive diagnostic tool for specific conditions. When ESR results are abnormal, they indicate the presence of inflammation, which can be caused by various reasons. Therefore, abnormal results should be followed by additional testing to determine the underlying cause. The ESR test measures the rate at which red blood cells settle in a vertical tube over the span of one hour, and results are reported in millimeters per hour. Choice A is incorrect because ESR results are not solely diagnostic for any specific condition. Choice B is incorrect as abnormal ESR results do not directly indicate a potentially fatal illness without further investigation. Choice D is incorrect as the results are reported in millimeters per hour, not per minute.

3. To properly read a meniscus,

• A. hold the measuring device at eye level and read the bottom of the curve of the liquid level
• B. hold the measuring device at eye level and read the top of the curve of the liquid level where the liquid adheres to the walls of the container.
• C. hold the measuring device at table level and, looking down into the measuring device, read the bottom of the curve of the liquid level.
• D. hold the measuring device at table level and, looking down into the measuring device, read the top of the curve of the liquid level.

Correct answer: A

Rationale: To properly read a meniscus, it is essential to hold the measuring device at eye level to avoid parallax error. Reading the bottom of the curve of the liquid level is correct because the meniscus is the concave or convex curve at the liquid's surface. Choice B is incorrect because reading the top of the curve where the liquid adheres to the walls of the container can lead to inaccurate measurements. Choices C and D are incorrect as they suggest holding the device at table level, which can introduce parallax error and result in an incorrect reading.

4. A patient is seen in the clinic for reports of "fainting episodes that started last week."? How would the nurse proceed with the examination?

• A. Blood pressure readings are taken in both arms and thighs.
• B. The patient is assisted to a lying position, and their blood pressure is taken.
• C. The patient's blood pressure is recorded in lying, sitting, and standing positions.
• D. The patient's blood pressure is recorded in lying and sitting positions; these numbers are then averaged to obtain a mean blood pressure.

Correct answer: C

Rationale: When a patient reports fainting episodes, it is crucial to assess for orthostatic hypotension. If the nurse suspects volume depletion, the patient has hypertension, is on antihypertensive medications, or has a history of fainting or syncope, blood pressure readings should be taken in three positions: lying, sitting, and standing. This assessment helps detect orthostatic hypotension, which can provide valuable information about the patient's condition. Taking blood pressure readings in multiple positions allows for a comprehensive evaluation of possible postural changes in blood pressure. Choices A, B, and D are incorrect because they do not cover the necessary positions to assess for orthostatic hypotension effectively.

5. A patient has suddenly developed shortness of breath and appears to be in significant respiratory distress. After calling the physician and placing the patient on oxygen, which of these actions is the best for the nurse to take when further assessing the patient?

• A. Count the patient's respirations.
• B. Bilaterally percuss the thorax, noting any differences in percussion tones.
• C. Call for a chest x-ray and wait for the results before beginning an assessment.
• D. Inspect the thorax for any new masses and bleeding associated with respirations.

Correct answer: B

Rationale: In a situation where a patient is in significant respiratory distress, bilaterally percussing the thorax to note any differences in percussion tones is a crucial nursing intervention. Percussion provides instant feedback regarding changes in underlying tissue density, which can give important clues about the patient's physical status. This hands-on assessment technique is readily available and can be performed promptly. Counting the patient's respirations, while important, may not provide as much detailed information as percussion. Ordering a chest x-ray and waiting for the results can cause a delay in assessing and addressing the patient's immediate needs. Inspecting the thorax for new masses and bleeding, although relevant, may not offer as much real-time information about the patient's condition compared to percussion.
