Nursing Elites

1. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?

• A. blood urea nitrogen
• B. serum calcium
• C. serum ammonia
• D. serum creatinine

Correct answer: C

Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.

2. Which of the following client statements indicates adequate understanding of preparation for electroencephalography?

• A. "I don't need to eat or drink after midnight."?
• B. "I need to wash my hair before the test."?
• C. "I need to remove metal jewelry."?
• D. "I can't take aspirin before the test."?

Correct answer: B

Rationale: The correct statement is, 'I need to wash my hair before the test.' Washing the hair is necessary to remove hair products that could interfere with electrode attachment to the scalp. Restricting food or drink is not required, except for avoiding caffeinated beverages. Removing metal jewelry is unnecessary for an electroencephalography procedure. Aspirin does not need to be avoided before the test; medications like anticonvulsants, tranquilizers, barbiturates, and sedatives are the ones that might need to be held.

3. While caring for the following clients, a pediatric nurse tells the charge nurse she must leave due to a family emergency. Which client would the charge nurse reassign to an LPN?

• A. An eight-year-old in diabetic ketoacidosis
• B. A six-year-old in sickle cell crisis
• C. A two-month-old with dehydration
• D. A five-year-old in skeletal traction

Correct answer: D

Rationale: The correct answer is a five-year-old in skeletal traction. This task is within the scope of practice for an LPN and would need minimal assistance from an RN. The children with diabetic ketoacidosis, sickle cell crisis, and dehydration require close observation, good assessment skills, IVF needs, and medications that would be better managed by an RN. Reassigning the child in skeletal traction to an LPN ensures appropriate care while allowing the RN to focus on the more critical cases.

4. The healthcare professional seeks to assess the renal function of an elderly client who is about to receive a nephrotoxic medication. Which of the following labs provides the best indicator for renal function?

• A. urinalysis
• B. creatinine and blood urea nitrogen
• C. chemistry of electrolytes
• D. creatinine clearance

Correct answer: D

Rationale: In the context of an elderly client, assessing renal function before administering a nephrotoxic medication is crucial. While urinalysis and blood urea nitrogen provide valuable information on hydration status and overall health clues, they are not specific indicators of renal function. The chemistry of electrolytes may show abnormalities in renal failure, but it does not directly measure the kidneys' ability to eliminate waste. Creatinine clearance, on the other hand, is considered the best indicator for renal function in the elderly. This test accounts for decreases in lean body mass that can affect blood creatinine levels and is widely used to estimate the glomerular filtration rate, reflecting the kidneys' filtration capability. Therefore, creatinine clearance is the most appropriate lab test to assess renal function in this scenario.

5. In a community hospital, a nurse is employed as a staff nurse and is supervised by a nurse manager. The nurse understands that in this position, the term authority most appropriately refers to which description?

• A. Accepting responsibility for the actions of others
• B. The official power to ensure that an organizational decision is enforced
• C. Bearing the legal responsibility for others' performance of tasks
• D. Taking responsibility for what staff members do

Correct answer: B

Rationale: The term authority refers to the official power of an individual to approve or command an action or to ensure that a decision is enforced. In the context of the nurse's position supervised by a nurse manager, having authority means having the official power to ensure that organizational decisions are carried out. Choice A, accepting responsibility for the actions of others, is more related to accountability rather than authority. Choice C, bearing the legal responsibility for others' performance of tasks, is more about legal liability rather than authority. Choice D, taking responsibility for what staff members do, is similar to choice A and is more about accountability rather than having the official power to enforce decisions. Therefore, the correct answer is B as it directly relates to the concept of authority in the context described.
