Nursing Elites

1. In an extreme situation and when no other resident or intern is available, should a nurse receive telephone orders, the order has to be correctly written and signed by the physician within:

• A. 24 hours
• B. 36 hours
• C. 48 hours
• D. 12 hours

Correct answer: B

Rationale: In an extreme situation where no other resident or intern is available, if a nurse receives telephone orders, the order has to be correctly written and signed by the physician within 36 hours. This time frame ensures timely documentation and validation of the orders. Choice A (24 hours) is too short a period for busy physicians to fulfill the task. Choice C (48 hours) is too long and delays the incorporation of physician orders into the patient's care plan. Choice D (12 hours) may not provide enough time for the physician to review and sign the order, especially in situations where immediate attention is not required.

2. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?

• A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
• B. Viscous fiber binds with bile in the intestine and is excreted in feces
• C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
• D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol

Correct answer: B

Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.

3. Poor nutrition results in delayed eruption and exfoliation of deciduous teeth and increased dental caries. Increased caries susceptibility in at-risk children may be related to changes in salivary composition caused by malnutrition.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: A

Rationale: Both statements are true. Poor nutrition can affect tooth development and increase the risk of dental caries in children.

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

5. The only IV fluid compatible with blood products is:

• A. D5LR C. NSS
• B. D5NSS D. Plain LR
• C.
• D.

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
