to properly read a meniscus

NCLEX RN Predictor Exam

1. 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.

2. 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.

3. A patient works with a nurse to establish outcomes. The nurse believes that one outcome suggested by the patient is not in the patient's best interest. What is the nurse's best action?

A. Remain silent.
B. Educate the patient that the outcome is not realistic.
C. Explore with the patient possible consequences of the outcome.
D. Formulate an appropriate outcome without the patient's input.

Correct answer: C

Rationale: In this scenario, the nurse should collaborate with the patient rather than impose personal opinions. While the nurse should respect the patient's autonomy, they also have a duty to provide guidance. By exploring possible consequences of the suggested outcome with the patient, the nurse can facilitate a discussion that helps the patient make an informed decision. This approach respects the patient's input while ensuring their well-being. Remaining silent (Choice A) may not address the issue, educating the patient unilaterally (Choice B) may be perceived as dismissive, and formulating an outcome without patient input (Choice D) disregards the patient's autonomy and preferences.

4. Which of the following sets of word parts means 'Pain'?

A. dynia and -algia
B. a- and an
C. ia and -ac
D. pathy and -osis

Correct answer: A

Rationale: The correct answer is 'dynia and -algia.' The word parts 'dynia' and '-algia' specifically relate to pain. 'Dynia' refers to pain, and '-algia' also denotes pain. Therefore, when combined, they form the meaning 'pain.' Choices B, C, and D are incorrect because 'a-' and 'an' do not relate to pain, 'ia' and '-ac' do not specifically convey pain, and 'pathy' and '-osis' are not word parts that directly signify pain.

5. The client is being discharged to a long-term care (LTC) facility. The nurse is preparing a progress note to communicate to the LTC staff the client's outcome goals that were met and those that were not. To do this effectively, the nurse should:

A. Formulate post-discharge nursing diagnoses
B. Draw conclusion about resolution of current client problems
C. Assess the client for baseline data to be used at the LTC facility
D. Plan the care that is needed in the LTC facility

Correct answer: B

Rationale: To effectively communicate the client's outcome goals that were met and those that were not to the LTC staff, the nurse should draw conclusions about the resolution of the current client problems. Terminal evaluation is performed to determine the client's condition at discharge, focusing on which goals were achieved and which were not. Formulating post-discharge nursing diagnoses (option A) is not the most appropriate action in this scenario as it focuses on identifying potential problems after discharge rather than evaluating achieved goals. Assessing the client for baseline data (option C) is not necessary at this point as the focus is on evaluating outcomes rather than collecting baseline data. Planning the care needed in the LTC facility (option D) is premature as this should be done on admission to the LTC facility and not during the discharge process.
