Nursing Elites

1. What is a major constituent of cell membranes?

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: B

Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.

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. While a team effort is necessary in the operating room (OR) for efficient and quality patient care delivery, the number of people in the room should be limited for infection control purposes. Which roles comprise this team?

• A. Surgeon, anesthesiologist, scrub nurse, radiologist, orderly
• B. Surgeon, assistants, scrub nurse, circulating nurse, anesthesiologist
• C. Surgeon, assistant surgeon, anesthesiologist, scrub nurse, pathologist
• D. Surgeon, assistant surgeon, anesthesiologist, intern, scrub nurse

Correct answer: B

Rationale: The roles typically present in an operating room team include the surgeon, assistants (which may include an assistant surgeon), scrub nurse, circulating nurse, and anesthesiologist. These roles are directly involved in the operation and patient care. Choice B is correct. Choice A includes a radiologist and an orderly, who are not typically part of the immediate surgical team in the OR. Choice C includes a pathologist, who usually works in a laboratory outside of the OR. Choice D includes an intern, who may or may not be part of the team, depending on the specific circumstances and hospital policy. These explanations make choices A, C, and D incorrect.

4. A client with cirrhosis and ascites is being cared for by a nurse. Which of the following interventions should the nurse include in the plan of care?

• A. Decrease the client's fluid intake.
• B. Increase the client's saturated fat intake.
• C. Increase the client's sodium intake.
• D. Decrease the client's carbohydrate intake.

Correct answer: D

Rationale: In a client with cirrhosis and ascites, decreasing carbohydrate intake is essential as it helps reduce the production of ascitic fluid. Excess carbohydrates can lead to fluid retention. Choices A, B, and C are incorrect. Decreasing fluid intake can worsen dehydration, increasing saturated fat intake is not recommended due to its impact on liver health, and increasing sodium intake can worsen fluid retention and exacerbate ascites in these clients.

5. A healthcare provider is evaluating a client who reports paresthesia of the hands and feet. The provider should identify this manifestation as an indication of which of the following dietary deficiencies?

• A. Iron
• B. Riboflavin
• C. Vitamin C
• D. Vitamin B12

Correct answer: D

Rationale: Correct! Vitamin B12 deficiency can lead to neurological symptoms, including paresthesia (tingling or numbness) of the hands and feet, due to its role in nerve health. Iron deficiency is more commonly associated with anemia symptoms like fatigue and pallor. Riboflavin deficiency can cause mouth and skin changes. Vitamin C deficiency is linked to scurvy symptoms like bleeding gums and easy bruising.
