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. A primigravida at term comes to the prenatal clinic and tells the nurse that she is having contractions every 5 min. The nurse monitors the client for one hour, using an external fetal monitor, and determines that the client’s contractions are 7 to 15 minutes apart, lasting 20 to 30 seconds, with mild intensity by palpation. What action should the nurse take?

• A. Tell the client to go directly to the hospital for admission to labor and delivery for active labor
• B. Send the client home and instruct her to call the clinic when her contractions occur 5 minutes apart for one hour
• C. Tell the client to check into the hospital within the next hour for evaluation of possible urinary tract infection
• D. Advise the client to rest and hydrate, then return if contractions become more regular

Correct answer: B

Rationale: The client should be instructed to call when contractions are 5 minutes apart for an hour to ensure she is in active labor before going to the hospital.

3. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who has a respiratory rate of 32 breaths/min and a heart rate of 110 beats/min. What action should the nurse take first?

• A. Administer a bronchodilator
• B. Encourage deep breathing and coughing
• C. Assess the client's oxygen saturation level
• D. Obtain an arterial blood gas

Correct answer: C

Rationale: The correct action for the nurse to take first is to assess the client's oxygen saturation level. In a client with COPD and abnormal respiratory and heart rates, determining the oxygen saturation helps evaluate the adequacy of oxygen exchange and the severity of respiratory distress. Administering a bronchodilator (choice A) can be appropriate but assessing oxygen saturation takes priority. Encouraging deep breathing and coughing (choice B) may not address the immediate need for oxygenation assessment. Obtaining an arterial blood gas (choice D) is important but typically follows the initial assessment of oxygen saturation.

4. When evaluating the preoperative teaching of a client scheduled for arthroscopic anterior cruciate ligament repair, which statement by the client indicates that the teaching was effective?

• A. I will use crutches to keep my weight off my knee
• B. I will stay home until a wheelchair is delivered
• C. I can use the trapeze bar and side rails on the bed to help me turn regularly
• D. I can put my full weight on my foot starting the day after surgery

Correct answer: A

Rationale: The correct answer is A. Using crutches indicates an understanding of weight-bearing restrictions post-surgery. Choice B is incorrect because waiting for a wheelchair is not related to postoperative mobility instructions. Choice C is incorrect as turning in bed using the trapeze bar and side rails does not address weight-bearing restrictions. Choice D is incorrect because putting full weight on the foot immediately after surgery contradicts the need to keep weight off the knee.

5. A client with chronic renal failure is being discharged with a prescription for erythropoietin (Epogen). Which statement indicates that the client understands the action of this medication?

• A. It helps my body make red blood cells
• B. It helps prevent infections
• C. It helps my kidneys excrete excess fluid
• D. It helps me breathe easier

Correct answer: A

Rationale: The correct answer is A: 'It helps my body make red blood cells.' Erythropoietin is a medication that stimulates the production of red blood cells in the body. Clients with chronic renal failure often develop anemia due to decreased erythropoietin production by the kidneys. This medication helps address that issue by increasing red blood cell production. Choices B, C, and D are incorrect because erythropoietin does not prevent infections, help kidneys excrete excess fluid, or assist with breathing; its primary action is to boost red blood cell production.
