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. One of the major functions of the kidneys in maintaining normal fluid balance is:

• A. the manufacture of antidiuretic hormone.
• B. the regulation of calcium and phosphate balance.
• C. the regulation of the pH of the extracellular fluid.
• D. the control of aldosterone levels.

Correct answer: C

Rationale: The correct answer is 'the regulation of the pH of the extracellular fluid.' The kidneys play a crucial role in maintaining normal fluid balance by regulating extracellular fluid and osmolarity through selective retention and excretion of fluids. Additionally, they regulate the pH of the extracellular fluid by retaining hydrogen ions and excreting metabolic wastes and toxic substances. Choice A is incorrect because antidiuretic hormone (ADH) is manufactured by the pituitary gland, not the kidneys. Choice B is incorrect as the regulation of calcium and phosphate balance is primarily controlled by the parathyroid gland. Choice D is incorrect as aldosterone levels are controlled by the adrenal glands, not the kidneys.

3. A healthcare professional is reviewing a patient's medical record. The record indicates the patient has limited shoulder flexion on the left. Which plane of movement is limited?

• A. Horizontal
• B. Sagittal
• C. Frontal
• D. Vertical

Correct answer: B

Rationale: The correct answer is 'Sagittal.' The sagittal plane divides the body into left and right halves, and movements in this plane involve flexion and extension. In this case, limited shoulder flexion on the left indicates a restriction in the forward and backward movement of the arm, which occurs in the sagittal plane. Choice A, 'Horizontal,' is incorrect as it refers to movements parallel to the ground. Choice C, 'Frontal,' is incorrect as it involves side-to-side movements. Choice D, 'Vertical,' is incorrect as it typically refers to up and down movements.

4. A nurse at an outpatient clinic is returning phone calls that have been made to the clinic. Which of the following calls should have the highest priority for medical intervention?

• A. A home health patient reports, "I am starting to have a breakdown of my heels."?
• B. A patient that received an upper extremity cast yesterday reports, "I can't feel my fingers in my right hand today."?
• C. A young female reports, 'I think I sprained my ankle about 2 weeks ago.'
• D. A middle-aged patient reports, 'My knee is still hurting from the TKR.'

Correct answer: B

Rationale: The correct answer is the patient who received an upper extremity cast yesterday and reports not being able to feel their fingers in the right hand. This situation indicates a potential neurovascular issue that requires immediate attention to prevent complications. The other options are of lesser priority: A - Breakdown of the heels, while concerning, is not an acute issue that necessitates immediate intervention. C - An ankle sprain that occurred two weeks ago is now subacute and unlikely to be an urgent medical concern. D - Pain in the knee following a total knee replacement (TKR) is common in the early postoperative period and is not unexpected.

5. A client is admitted to telemetry with a diagnosis of diabetes at 3pm. At 10pm, the client is unresponsive. BP is 98/64, Resp 38, HR 100, T 97. The nurse notes a fruity smell on the client's breath. The nurse recognizes that the client is in which acid-base imbalance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: C

Rationale: Based on the client's unresponsiveness, fruity breath smell, and the presence of diabetes, the nurse can infer that the client is experiencing diabetic ketoacidosis (DKA). DKA is a complication of diabetes characterized by the accumulation of ketones in the body, leading to metabolic acidosis. The fruity breath smell is due to the presence of ketones. Therefore, the correct acid-base imbalance in this scenario is metabolic acidosis. Choice A, respiratory acidosis, is incorrect because the scenario does not provide evidence of primary respiratory dysfunction. Choice B, respiratory alkalosis, is incorrect as the client's condition does not align with the typical causes and symptoms of respiratory alkalosis. Choice D, metabolic alkalosis, is incorrect as the symptoms and history provided do not suggest a state of metabolic alkalosis.
