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. A healthcare professional is preparing to perform nasal tracheal suctioning for a client. Which of the following is an appropriate action for the healthcare professional to take?

• A. Hold the suction catheter with the non-dominant hand.
• B. Apply suctioning for 20 to 30 seconds.
• C. Place the catheter in a clean and dry location for later use.
• D. Use surgical asepsis when performing the procedure.

Correct answer: D

Rationale: Using surgical asepsis when performing nasal tracheal suctioning is crucial to prevent infection. Choice A is incorrect because the suction catheter should be held with the dominant hand to ensure better control and precision during the procedure. Choice B is incorrect as suctioning should be applied for no longer than 10 to 15 seconds to avoid trauma to the mucous membranes. Choice C is incorrect as the catheter should be disposed of properly after single-use to prevent cross-contamination and infection.

3. When entering the room of an adult male, the nurse finds that the client is very anxious. Before providing care, what action should the nurse take?

• A. Divert the client’s attention
• B. Call for additional help from staff
• C. Document the planned action
• D. Re-assess the client's situation

Correct answer: D

Rationale: Re-assessing the client's situation before providing care is the most appropriate action in this scenario. By re-evaluating the client, the nurse can better understand the cause of the anxiety and tailor the care accordingly. Diverting the client's attention (Choice A) may not address the underlying issue causing anxiety. Calling for additional help (Choice B) is not the initial step required unless there is an urgent need. Documenting the planned action (Choice C) should come after reassessing the client to ensure accuracy and relevance.

4. A client with a history of chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute via nasal cannula. The client is short of breath and has a pulse oximetry reading of 88%. What action should the LPN take first?

• A. Increase the oxygen flow rate to 4 liters per minute.
• B. Reposition the client to a high Fowler's position.
• C. Notify the healthcare provider of the client's condition.
• D. Encourage the client to use pursed-lip breathing.

Correct answer: B

Rationale: Repositioning the client to a high Fowler's position should be the first action taken by the LPN. This position helps improve oxygenation by maximizing lung expansion, making it easier for the client to breathe. Increasing the oxygen flow rate without addressing positioning may not fully optimize oxygen delivery. Notifying the healthcare provider should come after immediate interventions. Encouraging pursed-lip breathing is beneficial but should follow the initial positioning to further assist the client in managing their breathing difficulty.

5. The healthcare provider prescribes the diuretic metolazone (Zaroxolyn) 7.5 mg PO. Zaroxolyn is available in 5 mg tablets. How much should the LPN/LVN plan to administer?

• A. 1/2 tablet.
• B. 1 tablet.
• C. 1 1/2 tablets.
• D. 2 tablets.

Correct answer: C

Rationale: To administer 7.5 mg of metolazone (Zaroxolyn), the LPN/LVN should plan to give 1 1/2 tablets since each tablet contains 5 mg. Choice A (1/2 tablet) would not provide the full prescribed dose. Choice B (1 tablet) would only deliver 5 mg, which is less than the prescribed dose. Choice D (2 tablets) would exceed the prescribed dose, resulting in 10 mg instead of the required 7.5 mg. Therefore, the correct answer is to administer 1 1/2 tablets to achieve the prescribed 7.5 mg.
