Nursing Elites

1. The physician wants to know if a client is tolerating their total parenteral nutrition. Which of the following laboratory tests is likely to be ordered?

• A. triglyceride level
• B. liver function tests
• C. a glucose tolerance test
• D. a complete blood count

Correct answer: B

Rationale: The liver is crucial in processing nutrients and medications received through total parenteral nutrition. Liver function tests assess various enzymes produced by the liver, including prothrombin time/partial prothrombin time, serum glutamic oxaloacetic and pyruvic transaminases, gamma glutamyl transpeptidase, albumin, and alkaline phosphatase. Monitoring these enzymes can help determine if the liver is functioning properly to metabolize the nutrients from TPN. Triglyceride levels (Choice A) primarily evaluate the body's ability to clear fats, not specifically related to TPN tolerance. A glucose tolerance test (Choice C) is used to diagnose diabetes by measuring blood glucose levels after ingesting a glucose-rich solution, not directly related to TPN tolerance. A complete blood count (Choice D) assesses blood components such as red blood cells, white blood cells, and platelets but does not provide specific information about TPN tolerance.

2. The death of a beloved spouse places the surviving partner in which type of crisis?

• A. maturational
• B. reactive
• C. nonreactive
• D. situational

Correct answer: D

Rationale: The correct answer is 'situational.' A situational crisis is an unexpected, unplanned event, such as the death of a spouse, which can lead to significant distress. Option A is incorrect because a maturational crisis is related to normal life transitions like getting married or retiring. Choices B and C are incorrect as they do not represent recognized crisis states in the context of the scenario provided.

3. While making rounds at 3 am, the nurse discovers a small fire in a client's room. What should the nurse do first?

• A. Remove the client from the room immediately.
• B. Leave the client's room to obtain a fire extinguisher.
• C. Instruct a nurse tech to pull the fire alarm.
• D. Evacuate all clients from the unit.

Correct answer: A

Rationale: During a fire emergency, the priority is the safety of the individual in the room where the fire is located. Removing the client from the room immediately is the first step in the RACE acronym for fire safety: Rescue/Remove, Alarm, Contain, and Extinguish. This action ensures the client's safety before addressing the fire itself. Choice B is incorrect as leaving the client's room to obtain a fire extinguisher can delay the immediate removal of the client from the danger. Choice C is incorrect as pulling the fire alarm should be done after ensuring the client's safety. Choice D is incorrect as evacuating all clients from the unit should come after ensuring the safety of the individual in immediate danger.

4. What are the major electrolytes in the extracellular fluid?

• A. potassium and chloride
• B. potassium and phosphate
• C. sodium and chloride
• D. sodium and phosphate

Correct answer: C

Rationale: The correct answer is sodium and chloride. These two electrolytes are the major components of extracellular fluid. Potassium and phosphate (Choice B) are not the major electrolytes in the extracellular fluid. Potassium is primarily an intracellular ion, and phosphate is more abundant in the intracellular fluid and bones. Sodium and phosphate (Choice D) are also not the major electrolytes in the extracellular fluid. Chloride plays a crucial role in maintaining electrolyte balance and is predominantly found in extracellular fluid alongside sodium.

5. The client asked about the role of leptin in the body. Which response should the nurse provide?

• A. It increases food intake in clients, thereby promoting obesity.
• B. It assists in the regulation of steroids.
• C. It increases the total fat mass of people who are obese.
• D. It might decrease the total fat mass in the bodies of people who are obese.

Correct answer: D

Rationale: Leptin is a protein hormone expressed in fat cells that regulates fat cell percentage in the body. It is associated with increased energy expenditure and decreased food intake through hypothalamic control. In obese individuals, there may be insensitivity or resistance to leptin's effects. Leptin influences other hormones like insulin and genetic factors related to fat regulation. Therefore, the correct response is that leptin might decrease total fat mass in obese individuals as it is involved in energy balance and fat regulation. Choices A, B, and C are incorrect because leptin does not increase food intake or promote obesity; it does not assist in the regulation of steroids, and it does not increase total fat mass in people who are obese.
