A nurse reviewing a client's record notes that the result of the client's latest Snellen chart vision test was 20/80. The nurse interprets the client's results in which way?
- A. The client is legally blind.
- B. The client has normal vision.
- C. The client can read at a distance of 20 feet what a client with normal vision can read at 80 feet.
- D. The client can read at a distance of 80 feet what a client with normal vision can read at 20 feet.
Correct Answer: D
Rationale: When interpreting visual acuity testing results using the Snellen chart, the recorded numeric fraction represents the distance the client is standing from the chart and the distance a normal eye could read that particular line. A reading of 20/80 means that the client can read at 20 feet what a client with normal vision can read at 80 feet. This indicates visual impairment but does not meet the criteria for legal blindness, which is defined as best-corrected vision in the better eye of 20/200 or worse. Normal visual acuity is 20/20. Therefore, the correct interpretation is that the client can read at a distance of 80 feet what a client with normal vision can read at 20 feet. Choice A is incorrect because 20/80 does not meet the criteria for legal blindness. Choice B is incorrect as the client's vision is impaired. Choice C is incorrect because it reverses the interpretation of the fraction.

Which reported symptom(s) would indicate a client with Addison's disease has received too much fludrocortisone (Florinef) replacement?
- A. Oily skin and hair
- B. Weight gain of 6 pounds in one week
- C. Loss of muscle mass in arms and legs
- D. Increased blood glucose level
Correct Answer: B
Rationale: Fludrocortisone replacement in Addison's disease involves mimicking the action of aldosterone, a mineralocorticoid that causes the retention of sodium and water. Excessive retention of sodium and water can lead to weight gain. Therefore, a sudden increase in weight, especially a significant amount like 6 pounds in one week, can indicate an overdose of fludrocortisone. Choices A, C, and D are incorrect because oily skin and hair, loss of muscle mass, and increased blood glucose levels are not typically associated with excessive fludrocortisone replacement.
Which of the following statements is correct about Maslow's hierarchy of needs?
- A. There are psychosocial interventions that may be applicable to all of the levels.
- B. There are physical interventions that may be applicable to all of the levels.
- C. Two of the levels may require physical intervention while four of the levels may require psychosocial intervention.
- D. Four of the levels may require physical intervention, while two of the levels may require psychosocial intervention.
Correct Answer: C
Rationale: The correct statement about Maslow's hierarchy of needs is that two of the levels may require physical intervention while four of the levels may require psychosocial intervention. Maslow's theory suggests that physiological and safety needs are more basic and may require physical interventions, while social, esteem, and self-actualization needs are more psychosocial. Choices A and B are incorrect as they wrongly suggest that all levels may require only one type of intervention. Choice D is incorrect because it inaccurately represents the balance of physical and psychosocial interventions in Maslow's hierarchy of needs.
The LPN participates in a home visit for a client with Type 2 Diabetes who has been taking Metformin for 3 years. The client states that for the past 3 months, they have been trying a vegan diet and experiencing fatigue, confusion, and mood changes. What is a likely cause of the new symptoms?
- A. vitamin B12 deficiency
- B. chronic hypoglycemia
- C. vitamin D deficiency
- D. increased tolerance to Metformin
Correct Answer: A
Rationale: The correct answer is vitamin B12 deficiency. Long-term use of Metformin can lead to vitamin B12 deficiency, and a vegan diet is low in vitamin B12. Symptoms of vitamin B12 deficiency include anemia, fatigue, confusion, and mood changes. Chronic hypoglycemia is unlikely in a client with Type 2 Diabetes who has been taking Metformin as it typically causes hyperglycemia. Vitamin D deficiency usually presents with symptoms related to bones and muscles, not confusion and mood changes. Increased tolerance to Metformin does not explain the client's new symptoms, which are more indicative of a nutritional deficiency like vitamin B12.
When a client and their family are facing the end stage of a terminal illness, where might they be best served?
- A. Rehabilitation center.
- B. Extended care facility.
- C. Hospice.
- D. Crisis intervention center.
Correct Answer: C
Rationale: When a client and their family are facing the end stage of a terminal illness, they are best served by Hospice. Hospice offers a more humanized alternative care for dying clients compared to hospitals, focusing on comfort and quality of life in the final stages of life. It provides a specialized interdisciplinary team of health care professionals who work together to manage client care. Choices A, B, and D are incorrect because a rehabilitation center focuses on physical therapy, an extended care facility provides long-term care for activities of daily living, and a crisis intervention center deals with immediate psychological or social crises, none of which cater to the specific needs of clients facing the end stage of a terminal illness.
When performing the confrontation test to assess peripheral vision, what action should the nurse take?
- A. Asks the client to identify a small object brought into the visual field
- B. Has the client cover one eye while the nurse covers one eye and slowly advances a target midline between them
- C. Covers one eye, while the client covers the opposite eye, and brings a small object into the visual field
- D. Positions at eye level with the client, covers one eye, and has the client cover the opposite eye, then brings a small object into the visual field
Correct Answer: D
Rationale: When performing the confrontation test to assess peripheral vision, the nurse should position at eye level with the client, cover one eye, and have the client cover the opposite eye. This approach allows the examiner to bring a small object into the visual field to evaluate the client's peripheral vision. The test aims to compare the client's peripheral vision with the examiner's vision to identify any visual field deficits. Choices A, B, and C are incorrect. Choice A pertains to testing color vision, which is not part of the confrontation test. Choice B describes a different procedure that involves advancing a target midline between the client and examiner, not the correct approach for the confrontation test. Choice C is inaccurate as it fails to include the essential step of positioning at eye level with the client, making it an incorrect representation of the confrontation test.
