Nursing Elites

1. 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.

2. The nurse is assessing the dental status of an 18-month-old child. How many teeth should the nurse expect to examine?

• A. 6
• B. 8
• C. 12
• D. 16

Correct answer: C

Rationale: An 18-month-old child should have approximately 12 teeth. In general, children begin dentition around 6 months of age. During the first 2 years of life, a quick guide to the number of teeth a child should have is as follows: Subtract the number 6 from the number of months in the age of the child. In this example, the child is 18 months old, so the formula is 18 - 6 = 12. The correct answer is 12. Choice A (6) is incorrect as it does not consider the child's age. Choices B (8) and D (16) are incorrect as they do not align with the dental development timeline and the specific age of the child in question.

3. 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.

4. A healthcare professional reviewing a client's record notes documentation that the client has melena. How does the healthcare professional detect the presence of melena?

• A. By checking the client's urine for blood
• B. By checking the client's stool for blood
• C. By checking the client's urine for a decrease in output
• D. By checking the client's bowel movements for diarrhea

Correct answer: B

Rationale: Melena' is the term used to describe abnormal black tarry stool that has a distinctive odor and contains digested blood. It usually results from bleeding in the upper gastrointestinal tract and is often a sign of peptic ulcer disease or small bowel disease. The presence of melena is detected by checking the client's stool for blood. Blood in the client's urine, decreased urine output, and diarrhea are not associated with the assessment for melena.

5. The patient is inquiring about the use of a PCA pump for pain management. Which statement by the patient indicates a need for additional education?

• A. "I will continue to report my pain score during assessments."?
• B. "I understand that there is a maximum dose per hour that I can receive regardless of how many times I press the button."?
• C. "I believe this new PCA pump will finally alleviate my back pain."?
• D. "I have more control over when and how much medication I receive."?

Correct answer: C

Rationale: The correct answer is, "I believe this new PCA pump will finally alleviate my back pain."? This statement indicates a need for additional education as it reflects an unrealistic expectation regarding pain management. It is essential for the patient to understand that while a PCA pump can provide effective pain relief, it may not completely eliminate pain. Option A is correct as it demonstrates the patient's understanding of the importance of reporting pain scores for proper pain management. Option B is correct as it shows the patient's awareness of the maximum dose limits to prevent overdose. Option D is correct as it highlights the patient's understanding of the control they have over their medication administration.
