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. Which lab value is critical for patients on warfarin therapy?

• A. Monitor INR
• B. Monitor potassium levels
• C. Monitor sodium levels
• D. Monitor platelet count

Correct answer: A

Rationale: The correct answer is to monitor INR levels for patients on warfarin therapy. INR monitoring is essential because it helps assess the clotting tendency of the blood and ensures that patients are within the therapeutic range to prevent both blood clots and excessive bleeding. Monitoring potassium levels (Choice B), sodium levels (Choice C), or platelet count (Choice D) is not specifically required for patients on warfarin therapy and does not directly impact the effectiveness or safety of the medication.

3. A client with heart failure is being assessed by a nurse. Which of the following findings indicates the client is experiencing fluid overload?

• A. Dry, hacking cough
• B. Bounding peripheral pulses
• C. Decreased urinary output
• D. Weight loss of 1 kg in 24 hours

Correct answer: C

Rationale: In clients with heart failure, decreased urinary output is a classic sign of fluid overload. The kidneys try to compensate for the increased volume by reducing urine output, leading to fluid retention. A dry, hacking cough (choice A) is more indicative of heart failure complications like pulmonary edema. Bounding peripheral pulses (choice B) are a sign of increased volume, but not specifically fluid overload. Weight loss of 1 kg in 24 hours (choice D) is not indicative of fluid overload but rather rapid fluid loss.

4. What is the primary purpose of administering insulin to a patient with diabetes?

• A. Regulate blood glucose levels
• B. Increase metabolism
• C. Prevent complications
• D. Promote insulin sensitivity

Correct answer: A

Rationale: The correct answer is A: 'Regulate blood glucose levels.' Administering insulin to a patient with diabetes helps regulate blood glucose levels by facilitating the uptake of glucose into cells, thereby lowering high blood sugar levels. This process aims to prevent hyperglycemia and its associated complications. Choice B, 'Increase metabolism,' is incorrect as the primary role of insulin is not to increase metabolism directly. Choice C, 'Prevent complications,' is partially correct as regulating blood glucose through insulin administration does help prevent complications associated with uncontrolled diabetes, but it is not the primary purpose. Choice D, 'Promote insulin sensitivity,' is incorrect as insulin itself is administered to compensate for the lack of endogenous insulin in diabetic patients, rather than to promote sensitivity to it.

5. A nurse is caring for a client who has a prescription for a high-protein diet. Which of the following foods should the nurse recommend?

• A. Almonds
• B. Cheddar cheese
• C. Chicken breast
• D. Pasta

Correct answer: C

Rationale: Chicken breast is an excellent choice for a high-protein diet as it is a lean source of protein. Almonds, while a good source of protein, also contain high amounts of fat. Cheddar cheese is high in protein but also high in saturated fat. Pasta is not a significant source of protein compared to chicken breast.
