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 nurse observes a nursing assistant performing AM care for a client with a new leg cast. Which action by the assistant will the nurse intervene?

• A. Lifting the affected leg with the palms of the hands
• B. Covering the affected leg with a blanket to avoid chills
• C. Placing plastic over the groin prior to bathing
• D. Elevating the casted leg on two pillows

Correct answer: B

Rationale: The correct answer is to intervene when the assistant covers the affected leg with a blanket to avoid chills. A new cast should not be covered to allow the heat from the cast to evaporate, preventing complications. Lifting the affected leg with the palms of the hands is appropriate for proper handling. Placing plastic over the groin prior to bathing is a standard practice to protect the client's privacy and maintain hygiene. Elevating the casted leg on two pillows helps reduce swelling and promote circulation, making it a suitable action.

3. A nurse is instructing a patient about the warning signs of Digitalis side effects. Which of the following side effects should the nurse tell the patient are sometimes associated with excessive levels of Digitalis?

• A. Seizures
• B. Muscle weakness
• C. Depression
• D. Anxiety

Correct answer: B

Rationale: The correct answer is 'Muscle weakness.' Palpitations and muscle weakness are commonly associated with excessive levels of Digitalis. Seizures, depression, and anxiety are not typically linked to Digitalis toxicity. Seizures could be more related to other medications or conditions, while depression and anxiety are not commonly reported side effects of Digitalis.

4. A nurse has been ordered to set up Buck's traction on a patient's lower extremity due to a femur fracture. Which of the following applies to Buck's traction?

• A. A weight greater than 10 lbs. should be used.
• B. The line of pull is upward at an angle.
• C. The line of pull is straight
• D. A weight greater than 20 lbs. should be used.

Correct answer: C

Rationale: The correct answer is that the line of pull is straight for Buck's traction. This type of traction is applied to maintain alignment and immobilization of fractures, typically involving the lower extremities. A straight line of pull helps to provide the necessary countertraction to keep the fractured bone in proper alignment. Choices A and D are incorrect because Buck's traction commonly uses a weight range between 5-10 lbs, and using a weight greater than 10 or 20 lbs would not be appropriate or safe. Choice B is incorrect as well since the line of pull for Buck's traction is straight, not upward at an angle.

5. Because of the possible nervous system side-effects that occur with isoniazid (Nydrazid) therapy, which supplementary nutritional agent would the nurse teach the client to take as a prophylaxis?

• A. Alpha tocopherol (vitamin E)
• B. Ascorbic acid (vitamin C)
• C. Calcitriol (vitamin D)
• D. Pyridoxine (vitamin B6)

Correct answer: D

Rationale: Pyridoxine is the correct choice in this scenario because it is used as a prophylaxis to prevent neuritis, a possible nervous system side-effect of isoniazid therapy. Neuritis is a condition that involves inflammation of the nerves and can be a side effect of isoniazid. Pyridoxine, also known as vitamin B6, helps prevent this side effect. Vitamin E (Alpha tocopherol), vitamin C (Ascorbic acid), and vitamin D (Calcitriol) do not specifically address the nervous system side-effects associated with isoniazid therapy, making them incorrect choices.
