Nursing Elites

1. When performing an eye examination, which area can a healthcare provider best visualize using an ophthalmoscope?

• A. Iris
• B. Cornea
• C. Optic disc
• D. Conjunctiva

Correct answer: C

Rationale: An ophthalmoscope is a tool used to visualize the internal structures of the eye during an examination. The optic disc, located on the internal surface of the retina, can be best visualized using an ophthalmoscope. The iris, cornea, and conjunctiva are superficial structures that can be examined without the need for an ophthalmoscope. Therefore, the correct answer is the optic disc. Choices A, B, and D are incorrect because they are external structures that can be examined directly without the use of an ophthalmoscope.

2. A Mexican American client with epilepsy is being seen at the clinic for an initial examination. The nurse understands which primary purpose of including cultural information in the health assessment?

• A. Confirm the medical diagnosis.
• B. Make accurate nursing diagnoses.
• C. Identify any hereditary traits related to the epilepsy.
• D. Determine what the client believes has caused the epilepsy.

Correct answer: D

Rationale: The primary purpose for including cultural information in the health assessment is to determine what the client believes has caused the illness. In Mexican American culture, epilepsy is seen as a reflection of physical imbalance. While gathering data on hereditary traits and formulating nursing diagnoses are important, they are not the primary reasons for including cultural information in the health assessment. It is crucial to understand the client's beliefs as they may impact their perceptions of health, treatment adherence, and overall care. It is not the nurse's role to confirm a medical diagnosis, as this is the responsibility of the healthcare provider.

3. 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).

4. What effect can medication bound to protein have?

• A. reduced drug availability
• B. limited distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

5. Which of the following values should be monitored closely while a client is on total parenteral nutrition?

• A. calcium
• B. magnesium
• C. glucose
• D. cholesterol

Correct answer: C

Rationale: Glucose is the correct value to monitor closely while a client is on total parenteral nutrition. Total parenteral nutrition solutions have high glucose concentrations, necessitating monitoring to prevent complications like hyperglycemia. Calcium, magnesium, and cholesterol are not typically closely monitored during total parenteral nutrition as they are not directly related to the solution's composition or potential associated complications.
