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 is checking laboratory values on a patient who has crackling rales in the lower lobes, 2+ pitting edema, and dyspnea with minimal exertion. Which of the following laboratory values does the nurse expect to be abnormal?

• A. Potassium.
• B. B-type natriuretic peptide (BNP).
• C. C-reactive protein (CRP).
• D. Platelets.

Correct answer: B

Rationale: The client's symptoms suggest heart failure. BNP is a neurohormone released from the ventricles due to increased pressure and stretch, as seen in heart failure. A BNP level greater than 51 pg/mL is often associated with mild heart failure, with higher levels indicating more severe heart failure. Potassium levels are not typically affected by heart failure. CRP is an inflammation indicator used to predict coronary artery disease risk, not directly related to heart failure in this case. The client's symptoms do not suggest bleeding or clotting abnormalities associated with platelet count issues, making platelets an unlikely abnormal value.

3. A nurse is instructing a patient on the order of sensations with the application of an ice water bath for a swollen right ankle. Which of the following is the correct order of sensations experienced with an ice water bath?

• A. cold, burning, aching, and numbness
• B. burning, aching, cold, and numbness
• C. aching, cold, burning, and numbness
• D. cold, aching, burning, and numbness

Correct answer: A

Rationale: The correct order of sensations experienced with an ice water bath is cold, burning, aching, and numbness, as stated by the acronym CBAN (cold, burn, ache, numbness). Option A is the correct sequence. Choice B is incorrect as it starts with burning, which typically follows the cold sensation. Choice C is incorrect as aching is usually felt after the burning sensation. Choice D is incorrect as aching usually occurs after the burning sensation.

4. After discontinuing a peripherally inserted central line (PICC), what information is most important for the nurse to record?

• A. How the client tolerated the procedure.
• B. The length and intactness of the central line catheter.
• C. The amount of fluid left in the IV solution container.
• D. That a dressing was applied to the insertion site.

Correct answer: B

Rationale: The most important information for the nurse to record after discontinuing a peripherally inserted central line (PICC) is the length and intactness of the central line catheter. This is crucial for assessing any potential complications or safety issues post-removal. Choices A, C, and D are not as critical as ensuring the condition of the central line catheter. While noting the client's tolerance of the procedure is relevant for their care assessment, evaluating the central line's integrity takes precedence in this scenario.

5. Which of the following microorganisms is easily transmitted from client to client on the hands of healthcare workers?

• A. mycobacterium tuberculosis
• B. clostridium tetani
• C. staphylococcus aureus
• D. human immunodeficiency virus

Correct answer: C

Rationale: The correct answer is staphylococcus aureus. Staphylococcus aureus microorganisms are ubiquitous and easily transmitted by healthcare workers who fail to conduct routine hand washing between clients. Staphylococcus aureus can reside on the skin and be transferred from one client to another if proper hand hygiene is not practiced. Mycobacterium tuberculosis is mainly transmitted through the airborne route, clostridium tetani is usually acquired through exposure to soil or dirt contaminated with tetanus spores, and human immunodeficiency virus is not easily transmitted through casual contact or on the hands of healthcare workers.
