Nursing Elites

1. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?

• A. Blood glucose of 350 mg/dL
• B. Serum bicarbonate of 18 mEq/L
• C. Arterial pH of 7.20
• D. Serum potassium of 5.5 mEq/L

Correct answer: C

Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.

2. During an assessment, a healthcare professional observes significant tenting of the skin over an older adult client's forearm. What factor should the healthcare professional primarily consider as a cause for this finding?

• A. Thin, parchment-like skin
• B. Loss of adipose tissue
• C. Dehydration
• D. Diminished skin elasticity

Correct answer: C

Rationale: Dehydration is the primary factor to consider in this scenario. Dehydration leads to decreased skin turgor and tenting, where the skin does not return to its normal position when pinched. While thin, parchment-like skin, loss of adipose tissue, and diminished skin elasticity can contribute to skin changes, they are not the primary cause of the significant tenting observed.

3. What action should the LPN/LVN take to prevent postoperative complications in a client who has undergone abdominal surgery?

• A. Encourage the client to use an incentive spirometer regularly.
• B. Assist the client in ambulating as soon as possible.
• C. Position the client in high Fowler's position.
• D. Encourage the client to cough and deep breathe regularly.

Correct answer: A

Rationale: Encouraging the client to use an incentive spirometer regularly is crucial in preventing postoperative complications after abdominal surgery. This action helps prevent atelectasis by promoting lung expansion and improving air exchange in the lungs, reducing the risk of respiratory complications. Assisting the client in ambulating early is important for preventing issues like deep vein thrombosis but may not directly address respiratory concerns postoperatively. Positioning the client in high Fowler's position can help with respiratory distress but is not as specific to preventing postoperative respiratory complications as using an incentive spirometer. While encouraging the client to cough and deep breathe is generally beneficial for lung expansion, using an incentive spirometer is more effective and targeted in preventing atelectasis after abdominal surgery.

4. The nurse is caring for a 17-month-old child with acetaminophen poisoning. Which laboratory reports should the nurse review first?

• A. Prothrombin time (PT) and partial thromboplastin time (PTT)
• B. Red blood cell and white blood cell counts
• C. Blood urea nitrogen and creatinine levels
• D. Liver enzymes (AST and ALT)

Correct answer: D

Rationale: In acetaminophen poisoning, liver damage is a significant concern due to the drug's metabolism in the liver. Monitoring liver enzymes such as AST and ALT is crucial as they indicate liver function and damage. Prothrombin time (PT) and partial thromboplastin time (PTT) (Choice A) are coagulation studies and are not the priority in acetaminophen poisoning. Red blood cell and white blood cell counts (Choice B) are not directly related to acetaminophen poisoning. Blood urea nitrogen and creatinine levels (Choice C) assess kidney function, but liver enzymes are more specific for evaluating liver damage in acetaminophen poisoning.

5. A client with a terminal illness is being educated by a healthcare provider about her decision to decline resuscitation in her living will. The client asks about the scenario of having difficulty breathing upon arrival at the emergency department.

• A. “We will apply oxygen through a tube in your nose.”
• B. “We will perform resuscitation efforts regardless of your wishes.”
• C. “You will receive only palliative care.”
• D. “We will ensure your comfort measures are met as per your advance directives.”

Correct answer: A

Rationale: Choice A is correct because applying oxygen through a tube in the nose provides comfort and aligns with the client's wishes for palliative care without resuscitation. This intervention can help alleviate breathing difficulties and maintain comfort without initiating full resuscitation efforts, respecting the client's decision. Choice B is incorrect as it goes against the client's expressed wish to decline resuscitation in her living will. Choice C is not the most appropriate response as it does not directly address the client's immediate concern of difficulty breathing and lacks specificity. Choice D, although focusing on comfort measures, is less specific than the correct choice A in addressing the client's immediate need for assistance with breathing.
