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. When a couple experiencing infertility presents for a fertility workup, which of the following procedures should the nurse prepare the couple to have first?

• A. Hysterosalpingography
• B. Semen analysis
• C. Endometrial biopsy
• D. Transvaginal ultrasound

Correct answer: B

Rationale: Semen analysis is the most appropriate initial diagnostic test for a couple experiencing infertility. It is the least invasive of the listed tests, and since male factor infertility contributes to around 35% of cases, assessing semen parameters early is crucial. Hysterosalpingography is a radiographic test to evaluate tubal patency and uterine cavity abnormalities. Endometrial biopsy assesses endometrial receptivity post-ovulation. Transvaginal ultrasound is mainly used in infertility treatment to monitor follicle development, oocyte maturity, and luteal phase defects. Choices A, C, and D are more invasive, require specialized expertise, and are costlier. If semen analysis yields normal results, further tests may be warranted.

3. 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.

4. 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.

5. All of the following factors, when identified in the history of a family, are correlated with poverty except:

• A. high infant mortality rate
• B. frequent use of Emergency Departments
• C. consultation with folk healers
• D. low incidence of dental problems

Correct answer: D

Rationale: Factors correlated with poverty often include a high infant mortality rate, frequent use of Emergency Departments, and consultation with folk healers, as these indicate limited access to healthcare. Dental problems are prevalent in poverty due to a lack of preventive care and access to treatments. High infant mortality is a significant issue linked with poverty as it reflects poor healthcare access. Families in poverty might resort to Emergency Departments for healthcare due to financial barriers. Consulting folk healers is common in communities with limited access to formal healthcare. However, a low incidence of dental problems is less likely in impoverished families due to the lack of preventive services and the presence of other health issues.
