Nursing Elites

1. A nurse assisting with data collection is preparing to assess the optic nerve. The nurse performs this examination by using which technique?

• A. Assessing visual acuity
• B. Inspecting the eyelids for ptosis
• C. Assessing pupil constriction
• D. Assessing ocular movements

Correct answer: A

Rationale: The correct technique to assess the optic nerve is by testing visual acuity and visual fields through confrontation. Visual acuity involves assessing the clarity of vision, which directly correlates with the function of the optic nerve. Inspecting the eyelids for ptosis is unrelated to optic nerve assessment. Assessing pupil constriction is more related to the assessment of cranial nerves controlling eye movements, particularly the oculomotor nerve. Assessing ocular movements is related to testing the abducens, oculomotor, and trochlear nerves, not specifically the optic nerve.

2. What is the threshold of dextrose concentrations that can safely be administered through a peripheral IV?

• A. Dextrose concentrations below 20% can be safely administered through a peripheral IV; dextrose concentrations above 20% should not be administered through a peripheral IV.
• B. Dextrose concentrations below 5% can be safely administered through a peripheral IV; dextrose concentrations above 5% should not be administered through a peripheral IV.
• C. Dextrose concentrations below 10% can be safely administered through a peripheral IV; dextrose concentrations above 10% should not be administered through a peripheral IV.
• D. Dextrose concentrations above 5% can be safely administered through a peripheral IV; dextrose concentrations below 5% should not be administered through a peripheral IV.

Correct answer: C

Rationale: Dextrose concentrations below 10% are considered safe for administration through a peripheral IV, as concentrations above this threshold can lead to phlebitis, causing inflammation of the vein. Concentrations above 10% should not be administered through a peripheral IV to prevent vein irritation. Choice A is incorrect because concentrations above 20% are too high for a peripheral IV. Choice B is incorrect as dextrose concentrations below 5% are too low to be effective. Choice D is incorrect because the statement is reversed, suggesting that concentrations above 5% are safe, which is not true.

3. When removing hard contact lenses from an unresponsive client, what should the nurse do?

• A. Gently irrigate the eye with an irrigating solution from the inner canthus outward.
• B. Grasp the lens with a gentle pinching motion.
• C. Don sterile gloves before attempting the procedure.
• D. Ensure that the lens is centered on the cornea before gently manipulating the lids to release the lens.

Correct answer: D

Rationale: When removing hard contact lenses, it is crucial to ensure that the lens is correctly positioned on the cornea before removal. Directly grasping the lens can potentially scratch the cornea, so it is essential to gently manipulate the lids to release the lens safely. Gently irrigating the eye is unnecessary and could be harmful, especially without the client's cooperation. Wearing sterile gloves is also unnecessary for this specific procedure. Therefore, the correct approach is to ensure the proper positioning of the lens and then gently manipulate the lids to release it. Options A and C are incorrect because irrigating the eye and wearing sterile gloves are not necessary for contact lens removal. Option B is incorrect as directly grasping the lens can be harmful to the cornea.

4. Which of the following client groups should the nurse recognize as the fastest-growing segment of the homeless population?

• A. single, adult men
• B. single mothers with 2 or 3 children
• C. runaway adolescents
• D. single, adult women

Correct answer: B

Rationale: Single mothers with two or three children are indeed the fastest-growing segment of the homeless population. These families, where the majority of children are under the age of five, make up more than one-third of the homeless population in the United States. While single, adult men have traditionally been the largest group in the homeless population, single mothers with children have been increasing in numbers. Runaway adolescents, although a significant group of homeless children, do not represent the fastest-growing segment of the homeless population. Single, adult women are not specified as the fastest-growing segment.

5. The client has an order for a 1,000 mL bag of fluids to be infused over 8 hours. What is the correct rate?

• A. 100 mL/hr
• B. 125 mL/min
• C. 125 mL/hr
• D. 80 mL/min

Correct answer: C

Rationale: To determine the correct infusion rate, divide the total volume of fluids (1,000 mL) by the total infusion time (8 hours), resulting in a rate of 125 mL/hr. This calculation ensures the appropriate administration of fluids over the specified time period. Choice A (100 mL/hr) is incorrect as it does not match the calculated rate based on the given information. Choice B (125 mL/min) is inaccurate because the question specifies the rate in hours, not minutes. Choice D (80 mL/min) is incorrect as it provides the rate in minutes rather than hours, which is the required unit for this scenario.
