1. When a client with a history of atrial fibrillation is admitted with a new onset of confusion, which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is an Electrocardiogram (ECG). When a client with a history of atrial fibrillation presents with new-onset confusion, an ECG is crucial to assess for cardiac ischemia, which could be a potential cause of the confusion. A chest X-ray (Choice B) is not typically the first-line diagnostic test for evaluating confusion in a client with atrial fibrillation. Arterial blood gases (ABGs) (Choice C) are more useful in assessing oxygenation and acid-base balance rather than the cause of confusion in this scenario. While an echocardiogram (Choice D) provides valuable information about cardiac structure and function, it is usually not the initial diagnostic test needed in the evaluation of acute confusion in a client with atrial fibrillation.

2. In a client with heart failure receiving digoxin (Lanoxin) and furosemide (Lasix), which laboratory value requires immediate intervention?

• A. Serum potassium of 4.0 mEq/L
• B. Blood glucose of 200 mg/dl
• C. Serum creatinine of 1.5 mg/dl
• D. Serum potassium of 3.2 mEq/L

Correct answer: D

Rationale: A serum potassium level of 3.2 mEq/L is low and concerning in a client receiving digoxin and furosemide. Hypokalemia increases the risk of digoxin toxicity, leading to life-threatening arrhythmias. Therefore, immediate intervention is necessary to prevent complications. The other options, serum potassium of 4.0 mEq/L, blood glucose of 200 mg/dl, and serum creatinine of 1.5 mg/dl, are within normal limits and do not pose immediate risks to the client in this scenario.

3. A 46-year-old male client who had a myocardial infarction 24 hours ago comes to the nurse's station fully dressed and wanting to go home. He tells the nurse that he is feeling much better at this time. Based on this behavior, which nursing problem should the nurse formulate?

• A. Ineffective coping related to denial.
• B. Risk for impaired cardiac function.
• C. Noncompliance related to lack of knowledge.
• D. Anxiety related to hospitalization.

Correct answer: A

Rationale: The correct answer is A: Ineffective coping related to denial. The client's desire to leave the hospital shortly after a myocardial infarction despite the severity of the condition indicates denial and ineffective coping. This behavior could lead to complications as the client may not adequately address his health needs. Choice B, Risk for impaired cardiac function, is not the most appropriate nursing problem in this scenario as the client's behavior is more indicative of psychological coping issues rather than a direct physiological risk at this moment. Choice C, Noncompliance related to lack of knowledge, does not align with the client's behavior of wanting to leave the hospital. Choice D, Anxiety related to hospitalization, may not be the best option as the client's behavior is more suggestive of denial rather than anxiety about being hospitalized.

4. A client with hyperthyroidism is admitted to the postoperative unit after subtotal thyroidectomy. Which of the client's serum laboratory values requires intervention by the nurse?

• A. Total calcium 5.0 mg/dL.
• B. Serum sodium 140 mEq/L.
• C. Serum potassium 4.0 mEq/L.
• D. Serum glucose 90 mg/dL.

Correct answer: A

Rationale: The correct answer is A. A calcium level of 5.0 mg/dL is critically low and could indicate hypoparathyroidism, a possible complication after thyroidectomy. Low calcium levels can lead to tetany, seizures, and cardiac dysrhythmias, requiring immediate intervention. Choices B, C, and D fall within the normal range and do not require immediate intervention in this scenario.

5. The client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value is most concerning?

• A. Serum potassium of 6.0 mEq/L
• B. Serum creatinine of 2.5 mg/dL
• C. Serum calcium of 8.0 mg/dL
• D. Hemoglobin of 10 g/dL

Correct answer: A

Rationale: A serum potassium level of 6.0 mEq/L is most concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications such as arrhythmias and cardiac arrest. Immediate intervention is required to lower potassium levels. Choice B, serum creatinine of 2.5 mg/dL, is elevated but expected in ESRD due to impaired kidney function. Choice C, serum calcium of 8.0 mg/dL, is within the normal range and not typically a priority in this situation. Choice D, hemoglobin of 10 g/dL, is slightly low but not an immediate concern for a client scheduled for hemodialysis unless significantly lower and causing severe symptoms.
