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. An allergic reaction is classified as what type of pharmacological effect?

• A. a therapeutic effect
• B. a side effect
• C. an adverse effect
• D. an incompatibility

Correct answer: C

Rationale: An allergic reaction is classified as an adverse effect because it is an unintended response to a medication that requires treatment. A side effect is an undesired but somewhat expected reaction to a drug that does not necessarily need intervention. Incompatibility refers to an unsuitable combination of substances that leads to an adverse effect. A therapeutic effect is the desired and intended outcome of a medication.

3. Which of the following foods is a complete protein?

• A. corn
• B. eggs
• C. peanuts
• D. sunflower seeds

Correct answer: B

Rationale: Eggs are considered a complete protein because they contain all nine essential amino acids required by the human body. In contrast, corn, peanuts, and sunflower seeds are incomplete proteins as they lack one or more essential amino acids. Corn, although a staple food for many cultures, is deficient in the amino acids lysine and tryptophan. Peanuts are low in the amino acid methionine, and sunflower seeds are low in lysine. Therefore, eggs are the correct answer as a complete protein source.

4. 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.

5. A nurse assisting with data collection of a client gathers both subjective and objective data. Which finding would the nurse document as subjective data?

• A. The client appears anxious.
• B. Blood pressure is 170/80 mm Hg.
• C. The client states that he has a rash.
• D. The client has diminished reflexes in the legs.

Correct answer: C

Rationale: Subjective data are information provided by the client about their symptoms, feelings, or experiences. In this case, the client reporting having a rash is subjective data because it is based on what the client says. Choices A, B, and D involve observations or measurements made by the nurse (anxious appearance, blood pressure, reflexes), which fall under objective data. Objective data are observable and measurable data obtained through physical examination, vital signs assessment, and laboratory tests.
