Nursing Elites

1. A client's telemetry monitor indicates the sudden onset of ventricular fibrillation. Which assessment finding should the nurse anticipate?

• A. Bounding erratic pulse.
• B. Regularly irregular pulse.
• C. Thready irregular pulse.
• D. No palpable pulse.

Correct answer: D

Rationale: Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic, asynchronous contractions of the ventricles, resulting in ineffective cardiac output. This leads to the absence of a palpable pulse. Nurses should be prepared to initiate immediate interventions such as defibrillation to restore normal cardiac rhythm in a client experiencing ventricular fibrillation.

2. A client with heart failure is prescribed digoxin (Lanoxin). Which instruction should the nurse include in the client's teaching plan?

• A. Take your pulse before each dose and hold the medication if your pulse is below 60 beats per minute.
• B. Increase your intake of foods high in potassium.
• C. Take the medication with a high-fiber meal to enhance absorption.
• D. Skip a dose if you feel dizzy or lightheaded.

Correct answer: A

Rationale: The correct instruction for a client prescribed digoxin is to take their pulse before each dose and hold the medication if the pulse is below 60 beats per minute. This is crucial to prevent digoxin toxicity, as digoxin can cause adverse effects when the pulse rate is too low. Monitoring the pulse regularly ensures safety and appropriate management of the medication.

3. A patient with cirrhosis of the liver and ascites is scheduled for a paracentesis. What should the nurse do to prepare the patient for the procedure?

• A. Have the patient void immediately before the procedure.
• B. Position the patient upright or semi-Fowler's in bed.
• C. Administer a full liquid diet.
• D. Encourage the patient to ambulate for 30 minutes.

Correct answer: A

Rationale: The correct preparation for a paracentesis in a patient with cirrhosis and ascites includes having the patient void immediately before the procedure. This is important to reduce the risk of bladder puncture during the paracentesis. Positioning for a paracentesis is typically upright or semi-Fowler's, not flat in bed. Administering a full liquid diet or encouraging ambulation for 30 minutes are not directly related to preparing a patient for a paracentesis procedure.

4. A client is admitted with diabetic ketoacidosis (DKA). Which assessment finding requires immediate intervention?

• A. Fruity breath odor.
• B. Blood glucose of 450 mg/dL.
• C. Deep, rapid respirations.
• D. Serum potassium of 5.2 mEq/L.

Correct answer: C

Rationale: The correct answer is C: Deep, rapid respirations (Kussmaul breathing). This is a sign of severe acidosis commonly seen in diabetic ketoacidosis (DKA) and requires immediate intervention. Kussmaul breathing helps to compensate for the metabolic acidosis by blowing off carbon dioxide. Prompt intervention is necessary to prevent further deterioration and potential respiratory failure. Fruity breath odor (Choice A) is a classic sign of DKA but does not require immediate intervention. While a blood glucose level of 450 mg/dL (Choice B) is high, it does not pose an immediate threat to the client's life. Serum potassium of 5.2 mEq/L (Choice D) is slightly elevated but not the most critical finding that requires immediate intervention in this scenario.

5. A healthcare professional is assessing a client with severe dehydration. Which finding indicates a need for immediate intervention?

• A. Heart rate of 110 beats per minute.
• B. Blood pressure of 90/60 mm Hg.
• C. Urine output of 20 ml/hour.
• D. Dry mucous membranes.

Correct answer: C

Rationale: A urine output of 20 ml/hour indicates severe dehydration and impaired renal function. This finding suggests a critical state where the kidneys are conserving water, leading to reduced urine output. Immediate intervention is required to restore fluid balance and prevent further complications associated with severe dehydration. Choice A, a heart rate of 110 beats per minute, may indicate dehydration but is not as severe as the critically low urine output. Choice B, a blood pressure of 90/60 mm Hg, can be seen in dehydration but is not as concerning as the extremely low urine output. Choice D, dry mucous membranes, is a common sign of dehydration but does not require immediate intervention compared to the severely reduced urine output.
