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. Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?

• A. skin
• B. adipose tissue
• C. skeletal muscle
• D. myocardium

Correct answer: D

Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.

3. A nurse provides instructions to a mother about crib safety for her infant. Which statement by the mother indicates a need for further instructions?

• A. ''Wood surfaces on the crib need to be free of splinters and cracks.''
• B. ''I need to keep large toys out of the crib.''
• C. ''The distance between the slats needs to be no more than 4 inches wide to prevent entrapment of my infant's head or body.''
• D. ''The drop side needs to be impossible for my infant to release.''

Correct answer: C

Rationale: The correct answer is, ''The distance between the slats needs to be no more than 4 inches wide to prevent entrapment of my infant's head or body.'' This statement indicates a need for further instructions as the distance between the slats should be no more than 2? inches to prevent entrapment of the infant's head and body, not 4 inches. Allowing a larger gap can pose a risk of entrapment or injury to the infant. Keeping large toys out of the crib is essential to prevent the infant from using them to climb out, which could result in serious injuries. Ensuring the drop side of the crib is impossible for the infant to release is crucial to prevent falls and injuries. Additionally, maintaining wood surfaces on the crib free of splinters, cracks, and lead-based paint is vital for the infant's safety and well-being.

4. The LPN has been given assignments by the RN. Which assignment should the LPN question as being beyond the scope of the LPN?

• A. The LPN is assigned to care for a client with diabetes mellitus who needs instructions reinforced on how to self-administer insulin.
• B. The LPN is assigned to reinforce discharge teaching about dressing changes and medications to a 35-year-old man.
• C. The LPN is assigned to care for a 75-year-old woman, hospitalized for dehydration, who is being discharged home today with no medications.
• D. The LPN is assigned to care for a woman with newly diagnosed leukemia who will be receiving her initial dose of chemotherapy.

Correct answer: D

Rationale: The LPN should be able to recognize when an assignment is beyond their scope of practice. Administering chemotherapy for leukemia is not within the scope of practice for the LPN, and this assignment should be questioned. Choices A, B, and C are within the scope of practice for an LPN. Reinforcing teaching on self-administration of insulin, assisting with discharge instructions on dressing changes, and caring for a client being discharged with no medications are all appropriate tasks for an LPN.

5. Which direction given to the nursing assistant is most likely to accomplish the task of getting a urine specimen delivered to the lab immediately after collection?

• A. "Make it a stat delivery."?
• B. "Please do it as soon as you can after break."?
• C. "This client is delirious, and we're worried about urinary sepsis."?
• D. "Take this client to the bathroom now and collect a urine specimen from this voiding. Take the specimen to the lab immediately."?

Correct answer: D

Rationale: Effective delegation depends on clear, concise direction that leaves no room for question or interpretation on the part of the one being delegated to. In this scenario, the most appropriate direction is to ensure the urine specimen is collected promptly and delivered to the lab immediately. Choice A is too vague and does not specify the urgency required. Choice B does not emphasize the immediate need for the specimen to be delivered. Choice C introduces unnecessary medical information that is beyond the scope of a nursing assistant and may cause confusion. Therefore, choice D is the correct answer as it provides clear instructions for immediate action without room for misunderstanding.
