Nursing Elites

1. When testing the function of the oculomotor, trochlear, and abducens nerves, which parameter does a nurse check to determine their function?

• A. Tongue symmetry
• B. Eye movements
• C. Facial symmetry
• D. Corneal reflex

Correct answer: B

Rationale: The correct answer is B: Eye movements. When assessing the oculomotor, trochlear, and abducens nerves, evaluating eye movements is crucial. This assessment includes checking the pupils for size, regularity, equality, light reactions, accommodation, and extraocular movements in various gaze positions. Tongue symmetry is primarily used to evaluate cranial nerve XII (hypoglossal nerve) function. Facial symmetry is a key indicator of cranial nerve VII (facial nerve) function. The corneal reflex assesses sensory afferents in cranial nerve V (trigeminal nerve) and motor efferents in cranial nerve VII (facial nerve).

2. What is a chemical reaction between drugs before their administration or absorption known as?

• A. a drug incompatibility
• B. a side effect
• C. an adverse event
• D. an allergic response

Correct answer: A

Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly occurs when drug solutions are mixed before intravenous administration but can also happen with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses typically occur after the drugs have been administered and absorbed, not before.

3. What is the intent of the Patient Self Determination Act (PSDA) of 1990?

• A. Enhance personal control over healthcare decisions.
• B. Encourage medical treatment decision making prior to need.
• C. Establish a federal standard for living wills and durable powers of attorney.
• D. Emphasize client education.

Correct answer: B

Rationale: The correct answer is B: The purpose of the PSDA is to encourage medical treatment decision-making before it becomes necessary. This legislation aims to empower individuals to make their own healthcare choices in advance. Choice A is incorrect because while enhancing personal control over healthcare decisions is important, the primary goal of the PSDA is to facilitate medical decision-making before the need arises. Choice C is incorrect as the PSDA does not establish a federal standard for living wills and durable powers of attorney; instead, it encourages individuals to create their own advance directives according to state-specific regulations. Choice D is incorrect because while client education is valuable, the main focus of the PSDA is on empowering individuals to plan for their future healthcare needs.

4. A nurse is preparing to listen to the apical heart rate in the area of the mitral valve in an adult client. The nurse should place the stethoscope on which part of the client's chest?

• A. Second left interspace
• B. Second right interspace
• C. Left lower sternal border
• D. Fifth left interspace at the midclavicular line

Correct answer: D

Rationale: The correct placement for auscultating the apical heart rate in the area of the mitral valve is the fifth left interspace at the midclavicular line. Placing the stethoscope in the second left interspace would be to listen to the pulmonic valve, the second right interspace is for the aortic valve, and the left lower sternal border is for the tricuspid valve.

5. If Ms. Barrett's distance vision is 20/30, which of the following statements is true?

• A. The client can read from 20' what a person with normal vision can read at 30'.
• B. The client can read from 30' what a person with normal vision can read at 20'.
• C. The client can read the entire chart from 30'.
• D. The client can read the chart from 20' with the left eye and from 30' with the right eye.

Correct answer: A

Rationale: When Ms. Barrett's distance vision is measured as 20/30, it means that she can read from 20 feet away what a person with normal vision can read at 30 feet. The numerator (20) represents the distance in feet between the chart and the client, while the denominator (30) indicates the distance at which a normal eye can read the chart. In this case, Ms. Barrett's vision is slightly worse than normal, as she needs to be closer to the chart to read it clearly. Therefore, choice A is correct. Choices B, C, and D are incorrect: Choice B reverses the distances, Choice C assumes the client can read the entire chart from 30 feet, and Choice D introduces information not related to the 20/30 measurement.
