Nursing Elites

1. A nurse is caring for a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min, and the PR interval is 0.24 seconds. What cardiac rhythm should the nurse interpret this finding as?

• A. First-degree AV block.
• B. Premature ventricular contraction.
• C. Sinus bradycardia.
• D. Atrial fibrillation.

Correct answer: A

Rationale: The correct answer is A: First-degree AV block. A PR interval of 0.24 seconds indicates a prolonged PR interval, which is characteristic of first-degree AV block. This rhythm is considered benign and often does not require treatment. Choice B, premature ventricular contraction, is characterized by early, abnormal ventricular contractions and would not be indicated by the findings provided. Choice C, sinus bradycardia, would present with a normal PR interval but a heart rate less than 60 beats per minute. Choice D, atrial fibrillation, is characterized by an irregularly irregular rhythm with no identifiable P waves, which does not align with the findings of a prolonged PR interval in this scenario.

2. A client with a new diagnosis of hypertension is receiving teaching from a nurse. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will check my blood pressure at least once a week.
• B. I will avoid eating foods high in potassium.
• C. I should exercise for 30 minutes at least 5 days a week.
• D. I will take my medication only when I feel dizzy.

Correct answer: C

Rationale: The correct answer is C. Regular exercise is an essential component in managing hypertension. Exercising for at least 30 minutes a day, at least 5 days a week, can help control blood pressure. Checking blood pressure regularly (choice A) is important, but not as indicative of understanding the teaching as the commitment to regular exercise. Avoiding foods high in potassium (choice B) is not a typical recommendation for managing hypertension. Taking medication only when feeling dizzy (choice D) is incorrect and potentially dangerous; medications should be taken as prescribed by the healthcare provider.

3. A nurse is preparing to administer an IV bolus of 0.9% sodium chloride to a client who is dehydrated. Which of the following actions should the nurse take?

• A. Administer the solution slowly over 24 hours
• B. Assess the client's lung sounds before administration
• C. Change the IV tubing every 12 hours
• D. Flush the IV line with 2 mL of heparin every 4 hours

Correct answer: B

Rationale: The correct action for the nurse to take is to assess the client's lung sounds before administering IV fluids. This is crucial to identify any signs of fluid overload, such as crackles or wheezes. Administering the solution slowly over 24 hours (choice A) is not appropriate for an IV bolus, which is a rapid infusion. Changing the IV tubing every 12 hours (choice C) is a standard practice for preventing infection but is not directly related to administering an IV bolus. Flushing the IV line with heparin every 4 hours (choice D) is a maintenance practice to prevent clot formation in the line, not specifically related to administering an IV bolus.

4. A nurse is assessing a client who has increased intracranial pressure (ICP). Which of the following findings should the nurse expect?

• A. Bradycardia.
• B. Increased level of consciousness.
• C. Tachycardia.
• D. Hyperactive bowel sounds.

Correct answer: C

Rationale: The correct answer is C: Tachycardia. In a client with increased intracranial pressure (ICP), tachycardia is a common finding. This is due to the body's compensatory mechanisms in response to the increased pressure. Bradycardia (choice A) is not typically associated with increased ICP and may indicate a different issue. Increased level of consciousness (choice B) is unlikely with increased ICP, as it often leads to altered mental status. Hyperactive bowel sounds (choice D) are not directly related to increased ICP and are more indicative of gastrointestinal issues.

5. A nurse is assessing a client who is receiving enteral nutrition via a nasogastric tube. Which of the following findings should the nurse report to the provider?

• A. Gastric pH of 2.5.
• B. Bowel sounds every 4 hours.
• C. Diarrhea of 250 mL in 24 hours.
• D. Gastric residual of 150 mL.

Correct answer: D

Rationale: A gastric residual of 150 mL may indicate delayed gastric emptying and should be reported to the provider.
