Nursing Elites

1. A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse report to the healthcare provider before the procedure?

• A. Serum potassium of 5.5 mEq/L
• B. Blood urea nitrogen (BUN) of 40 mg/dl
• C. Serum potassium of 6.0 mEq/L
• D. Serum creatinine of 2.5 mg/dl

Correct answer: C

Rationale: A serum potassium level of 6.0 mEq/L is dangerously high for a client with chronic kidney disease (CKD) scheduled for hemodialysis. High potassium levels can lead to cardiac complications such as arrhythmias. Therefore, it is crucial to report this value to the healthcare provider before the procedure to prevent any potential serious complications. Choices A, B, and D are not as critical in the context of preparing for a hemodialysis session. Serum potassium levels above 6.0 mEq/L require immediate attention to ensure patient safety.

2. During orientation, a newly hired nurse demonstrates suctioning of a tracheostomy in a skills class. After the demonstration, the supervising nurse expresses concern that the demonstrated procedure increased the client's risk for which problem?

• A. Infection
• B. Hypoxia
• C. Bleeding
• D. Bronchospasm

Correct answer: A

Rationale: The correct answer is A: Infection. Improper suctioning techniques can introduce pathogens, increasing the risk of infection. Choice B, Hypoxia, is incorrect as it is more related to inadequate oxygen supply. Choice C, Bleeding, is not typically associated with suctioning a tracheostomy unless done too aggressively. Choice D, Bronchospasm, is not directly linked to suctioning but may occur due to other triggers in patients with sensitive airways.

3. A client with a history of myocardial infarction is admitted with chest pain. Which laboratory value should the nurse monitor closely?

• A. White blood cell count
• B. Serum creatinine
• C. Troponin level
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C: Troponin level. Troponin levels should be closely monitored in a client with chest pain and a history of myocardial infarction to assess for ongoing myocardial injury. Troponin is a specific marker for myocardial damage. Monitoring white blood cell count (choice A) is not directly related to myocardial infarction. Serum creatinine (choice B) is more indicative of renal function rather than cardiac status. Hemoglobin level (choice D) is important but does not directly reflect ongoing myocardial injury.

4. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which intervention should the nurse implement first?

• A. Administer oxygen therapy as prescribed.
• B. Elevate the head of the bed.
• C. Assess the client's level of consciousness.
• D. Obtain a sputum culture.

Correct answer: A

Rationale: Administering oxygen therapy as prescribed is the initial priority when managing an exacerbation of COPD. In COPD exacerbations, the primary concern is hypoxemia due to impaired gas exchange. Administering oxygen helps to improve oxygenation and prevent further complications. Elevating the head of the bed can aid in breathing comfort but is not the priority over ensuring adequate oxygen supply. Assessing the client's level of consciousness is important but comes after ensuring oxygenation. Obtaining a sputum culture is relevant for identifying pathogens but is not the immediate priority in addressing hypoxemia.

5. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.
