Nursing Elites

1. 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.

2. A nurse is preparing to assess a client for the presence of the Tinel sign. Which action does the nurse take to elicit this sign?

• A. Testing for the strength of each muscle joint
• B. Percussing at the location of the median nerve
• C. Checking for repetitive movements in the joints
• D. Asking the client to flex the wrist 90 degrees while holding the hands back to back

Correct answer: B

Rationale: The Tinel sign is elicited by percussing at the location of the median nerve at the wrist. In carpal tunnel syndrome, this test can produce burning and tingling along the nerve's distribution. Choices A, C, and D are incorrect. Testing for the strength of each muscle joint and checking for repetitive movements in the joints involve different assessments unrelated to the Tinel sign. Asking the client to flex the wrist 90 degrees while holding the hands back to back is associated with the Phalen test, which is another evaluation for carpal tunnel syndrome.

3. A nurse is interviewing an older adult while assisting with data collection. Which client comment regarding vision requires immediate discussion with the health care provider?

• A. "If I go from a very bright room to a very dark room, I have some trouble adjusting."
• B. "I have to hold my newspaper farther and farther away from me when I read."
• C. "I have a little trouble telling if my same-colored shirts and blouses actually match; the colors seem the same to me."
• D. "It looks like I have a blank spot in the middle of what I'm trying to see."

Correct answer: D

Rationale: The correct answer is "It looks like I have a blank spot in the middle of what I'm trying to see." Seeing blank spots in the middle of an object is a sign of central vision loss, which is a symptom of macular degeneration. Macular degeneration is a serious condition that requires immediate discussion with a healthcare provider to prevent further vision loss. Choice A, mentioning difficulty adjusting between bright and dark rooms, is a common issue related to changes in lighting and not a cause for immediate concern. Choice B, having to hold objects farther away when reading, is indicative of presbyopia, a normal age-related change in vision. Choice C, experiencing slight changes in color perception, is also a common age-related change and not an urgent issue that necessitates immediate discussion with a healthcare provider.

4. A nurse is preparing to assess the dorsalis pedis pulse. The nurse palpates this pulse by placing the fingertips in which location?

• A. Behind the knee
• B. Lateral to the extensor tendon of the big toe
• C. In the groove between the malleolus and the Achilles tendon
• D. Below the inguinal ligament, halfway between the pubis and the anterior superior iliac spines

Correct answer: B

Rationale: The correct location to palpate the dorsalis pedis pulse is lateral to and parallel with the extensor tendon of the big toe. Choices A, C, and D describe the locations for other pulses - popliteal, posterior tibial, and femoral artery respectively. The popliteal pulse is found behind the knee, the posterior tibial pulse is located in the groove between the malleolus and the Achilles tendon, and the femoral artery is situated below the inguinal ligament, halfway between the pubis and the anterior superior iliac spines.

5. What causes an older female client's hair to turn gray?

• A. ''A loss of melanin occurs in the normal aging process.''
• B. ''The number of sweat glands and blood vessels decreases in the normal aging process.''
• C. ''The skin on the scalp becomes thin, causing moisture to escape.''
• D. ''It is caused by hereditary factors.''

Correct answer: A

Rationale: The correct answer is 'A loss of melanin occurs in the normal aging process.' Graying hair in older adults is primarily due to a decrease in the number of melanocytes responsible for providing pigment and hair color. This reduction in melanin production leads to gray hair. The other choices are incorrect. While it is true that the skin becomes thinner with aging and the number of sweat glands and blood vessels decreases, these changes are not directly related to graying hair. Additionally, hereditary factors can influence when graying starts, but they do not cause the graying of hair itself.
