Nursing Elites

1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. Assessment findings of a 3-hour-old newborn include: axillary temperature of 97.7°F, heart rate of 140 beats/minute with a soft murmur, and irregular respiratory rate at 42 breaths/min. Based on these findings, what action should the nurse implement?

• A. Place a pulse oximeter on the heel
• B. Swaddle the infant in a warm blanket
• C. Record the findings on the flow sheet
• D. Check the vital signs in 15 minutes

Correct answer: C

Rationale: The correct answer is to record the findings on the flow sheet. These assessment findings are within normal limits for a 3-hour-old newborn. The axillary temperature of 97.7°F, heart rate of 140 beats/minute with a soft murmur, and irregular respiratory rate of 42 breaths/min are all expected in a newborn. No immediate intervention is needed, so the nurse should document these normal findings for future reference. Placing a pulse oximeter on the heel or swaddling the infant in a warm blanket is not indicated as the vital signs are within normal limits. Checking the vital signs in 15 minutes is unnecessary since the current findings are normal.

3. In attempting to develop a therapeutic relationship with a male adult client transferred to a psychiatric facility after being treated for a self-inflicted gunshot wound, which information is most important for the nurse to determine?

• A. The family's reaction to this situation
• B. The nurse's feelings about this client
• C. What losses the client recently experienced
• D. Why the client attempted to kill himself

Correct answer: C

Rationale: Understanding what losses the client recently experienced is crucial for the nurse in developing a therapeutic relationship. This information helps the nurse comprehend the client's emotional state, the potential triggers for the self-harm behavior, and provides insights into the client's current psychological and social challenges. Choice A, the family's reaction, may be important but is secondary to understanding the client's own experiences. Choice B, the nurse's feelings, is not relevant as the focus should be on the client. Choice D, why the client attempted suicide, is important but delving into recent losses can provide a broader context for the client's emotional distress and suicidal behavior.

4. A nurse is planning care for a client who has a new prescription for metoprolol (Lopressor). Which assessment finding should the nurse report to the healthcare provider before administering the medication?

• A. Heart rate of 50 beats per minute
• B. Blood pressure of 90/60 mm Hg
• C. Respiratory rate of 20 breaths per minute
• D. Temperature of 99°F (37.2°C)

Correct answer: A

Rationale: A heart rate of 50 beats per minute is a concerning finding that should be reported before administering metoprolol. Metoprolol is a beta-blocker that can further lower the heart rate, so a heart rate of 50 bpm indicates potential bradycardia, which is a contraindication for administering this medication. Choices B, C, and D are within normal ranges and do not pose immediate concerns related to metoprolol administration.

5. The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?

• A. Blood glucose of 140 mg/dL
• B. White blood cell count of 8000/mm³
• C. Serum potassium of 3.8 mEq/L
• D. Serum calcium of 7.8 mg/dL

Correct answer: D

Rationale: The correct answer is D. A serum calcium level of 7.8 mg/dL requires immediate intervention due to the risk of hypocalcemia. Hypocalcemia can lead to serious complications such as tetany, seizures, and cardiac arrhythmias. The other laboratory findings are within normal limits or slightly elevated, which do not pose an immediate threat to the client's health in this scenario.
