1. What is the conversion of genetic information in RNA into a sequence of amino acids?

• A. translation
• B. transcription
• C.
• D.

Correct answer: A

Rationale: The correct answer is 'translation.' Translation is the process where the genetic information in messenger RNA (mRNA) is decoded to produce a specific sequence of amino acids, forming a protein. This process occurs at ribosomes within the cell. Option B, 'transcription,' is incorrect as transcription is the process of synthesizing mRNA from a DNA template. Options C and D are irrelevant as they are not related to the conversion of genetic information into amino acids.

2. Can fluid retention cause lab values to be deceptively high, whereas dehydration may cause the values to be deceptively low?

• A. TRUE
• B. FALSE
• C. Not always
• D. Sometimes

Correct answer: B

Rationale: The statement is incorrect. Fluid retention generally results in lab values appearing deceptively low, not high, because the excess fluid dilutes the concentration of substances in the blood. Conversely, dehydration can make lab values appear deceptively high as the reduced fluid volume in the body means substances in the blood are less diluted. Choices 'C: Not always' and 'D: Sometimes' are not specific and do not directly address the statement in the question, hence they are incorrect.

3. A healthcare provider is assessing a client who has a stage III pressure ulcer that is healing poorly. The provider should identify that which of the following vitamin deficiencies increases the client’s risk for delayed wound healing?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin E
• D. Vitamin B6

Correct answer: A

Rationale: Corrected Rationale: Vitamin C deficiency can impair collagen synthesis and delay wound healing, making it crucial for recovery from pressure ulcers. Incorrect Rationales: - Vitamin D deficiency is associated with bone health, not specifically wound healing. - Vitamin E deficiency can lead to neurological and immune system issues but is not directly linked to delayed wound healing. - Vitamin B6 deficiency can cause skin rashes and neurological symptoms but is not a primary factor in delayed wound healing.

4. What does oliguria lead to in patients with acute kidney injury?

• A. Hypophosphatemia and overgrowth of bone tissue
• B. An increase in blood potassium levels due to excessive excretion of parathyroid hormone
• C. Sodium retention and elevated levels of potassium
• D. Edema due to increased urine production

Correct answer: C

Rationale: In patients with acute kidney injury, oliguria (reduced urine output) often results in sodium retention and hyperkalemia (elevated levels of potassium). This is due to the kidneys' decreased capacity to excrete these substances. Choice A is incorrect because hypophosphatemia and overgrowth of bone tissue are not direct consequences of oliguria in acute kidney injury. Choice B is incorrect because an increase in blood potassium levels is not caused by excessive excretion of parathyroid hormone but rather by decreased excretion of potassium. Choice D is incorrect because edema is not caused by increased urine production but rather by fluid overload due to decreased urine output.

5. Which mineral-containing amino acids help to form the shape of proteins?

• A. phosphorus
• B. sulfur
• C. selenium
• D. iron

Correct answer: B

Rationale: The correct answer is B: sulfur. Sulfur-containing amino acids like cysteine and methionine play a crucial role in forming disulfide bonds within proteins. These bonds are essential for the proper folding and structural stability of proteins. Phosphorus (choice A), selenium (choice C), and iron (choice D) do not directly contribute to shaping proteins through bond formation.
