1. What is the intent of the Patient Self Determination Act (PSDA) of 1990?

A. Enhance personal control over healthcare decisions.
B. Encourage medical treatment decision making prior to need.
C. Establish a federal standard for living wills and durable powers of attorney.
D. Emphasize client education.

Correct answer: B

Rationale: The correct answer is B: The purpose of the PSDA is to encourage medical treatment decision-making before it becomes necessary. This legislation aims to empower individuals to make their own healthcare choices in advance. Choice A is incorrect because while enhancing personal control over healthcare decisions is important, the primary goal of the PSDA is to facilitate medical decision-making before the need arises. Choice C is incorrect as the PSDA does not establish a federal standard for living wills and durable powers of attorney; instead, it encourages individuals to create their own advance directives according to state-specific regulations. Choice D is incorrect because while client education is valuable, the main focus of the PSDA is on empowering individuals to plan for their future healthcare needs.

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

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

Correct answer: B

Rationale: The correct answer is 'eggs.' Eggs are considered a complete protein as they contain all nine essential amino acids required by the body. On the other hand, corn, peanuts, and sunflower seeds are incomplete proteins, meaning they lack one or more of the essential amino acids needed by the body for optimal health. Corn, peanuts, and sunflower seeds are plant-based proteins that are deficient in one or more essential amino acids, unlike eggs, which are a high-quality complete protein source.

3. Which condition is associated with inadequate intake of vitamin C?

A. rickets
B. marasmus
C. kwashiorkor
D. scurvy

Correct answer: D

Rationale: Scurvy is indeed associated with inadequate intake of vitamin C. Vitamin C deficiency leads to scurvy, which is characterized by weakness, anemia, gum disease, and skin hemorrhages. Choices A, B, and C are incorrect because rickets is caused by vitamin D deficiency, marasmus is due to severe malnutrition leading to wasting, and kwashiorkor is a form of severe protein-energy malnutrition.

4. A nurse assisting with data collection notes that the client's skin is very dry. The nurse documents this finding using which term?

A. Xerosis
B. Pruritus
C. Seborrhea
D. Actinic keratoses

Correct answer: A

Rationale: Dry skin is also called xerosis. In this condition, the epidermis lacks moisture or sebum and is often marked by a pattern of fine lines, scaling, and itching. Xerosis is the correct term for very dry skin. Pruritus is the symptom of itching, an uncomfortable sensation that prompts the urge to scratch the skin, but it does not specifically refer to dry skin. Seborrhea is a skin condition characterized by overproduction of sebum, leading to excessive oiliness or dry scales, not necessarily indicating very dry skin. Actinic keratoses are sun-related skin lesions that are premalignant and not associated with dry skin.

5. A nurse is preparing to screen a client's vision with the use of a Snellen chart. The nurse uses which technique?

A. Tests the right eye, then tests the left eye, and finally tests both eyes together
B. Assesses both eyes together, then assesses the right and left eyes separately
C. Asks the client to stand 40 feet from the chart and read the largest line on the chart
D. Asks the client to stand 40 feet from the chart and read the line that can be read 200 feet away by someone with unimpaired vision

Correct answer: A

Rationale: To test visual acuity with the use of a Snellen chart, the nurse places the chart in a well-lit spot at the client's eye level, with the client positioned exactly 20 feet from the chart. The client shields one eye at a time with an opaque card during the test. After testing each eye separately, both eyes are assessed together. The client is asked to read the smallest line of letters visible and encouraged to read the next smallest line as well. Therefore, option A is correct as it describes the correct technique of testing one eye at a time before assessing both eyes together. Option B is incorrect as it assesses both eyes together first, which is not the standard procedure. Options C and D are incorrect as they suggest standing 40 feet from the chart, which contradicts the standard distance of 20 feet for a Snellen chart test.
