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. Several clients on a telemetry unit are scheduled for discharge in the morning, but a telemetry-monitored bed is needed immediately. The charge nurse should make arrangements to transfer which client to another medical unit?

• A. Learning to self-administer insulin injections after being diagnosed with diabetes mellitus
• B. Ambulatory following coronary artery bypass graft surgery performed six days ago
• C. Wearing a sling immobilizer following permanent pacemaker insertion earlier that day
• D. Experiencing syncopal episodes resulting from the dehydration caused by severe diarrhea

Correct answer: A

Rationale: The correct answer is A because transferring a stable client who is learning self-care, such as self-administering insulin injections after being diagnosed with diabetes mellitus, provides the needed telemetry-monitored bed without compromising the client's care. Choice B should not be transferred as the client is ambulatory following surgery and does not require telemetry monitoring. Choice C should not be transferred as the client is wearing a sling immobilizer following pacemaker insertion, which requires close monitoring. Choice D should not be transferred as the client is experiencing syncopal episodes due to severe dehydration, necessitating telemetry monitoring for immediate intervention.

3. The nurse is caring for a client who has a chest tube in place following a pneumothorax. The nurse notes that there is continuous bubbling in the water seal chamber of the chest tube drainage system. What action should the nurse take?

• A. Check for kinks in the tubing
• B. Notify the healthcare provider
• C. Replace the chest tube drainage system
• D. Reinforce the chest tube dressing

Correct answer: B

Rationale: The correct action for the nurse to take when observing continuous bubbling in the water seal chamber of the chest tube drainage system is to notify the healthcare provider. Continuous bubbling indicates a possible air leak, and the healthcare provider needs to be informed to assess the situation and take appropriate actions. Checking for kinks in the tubing (Choice A) may be done initially but is not the priority when continuous bubbling is present. Replacing the chest tube drainage system (Choice C) and reinforcing the chest tube dressing (Choice D) are not immediate actions needed in response to continuous bubbling in the water seal chamber.

4. A client receiving amlodipine (Norvasc), a calcium channel blocker, develops 1+ pitting edema around the ankles. It is most important for the nurse to obtain what additional client data?

• A. Bladder distention
• B. Serum albumin level
• C. Abdominal girth
• D. Breath sounds

Correct answer: D

Rationale: The correct answer is 'D. Breath sounds.' When a client receiving amlodipine develops edema, it is crucial to assess for potential heart failure, a side effect of the medication. Checking breath sounds helps in identifying any signs of pulmonary edema, a severe complication of heart failure. Choices A, B, and C are less relevant in this context. Bladder distention could be associated with urinary issues, serum albumin level with malnutrition or liver disease, and abdominal girth with gastrointestinal problems, none of which directly relate to the potential heart failure induced by amlodipine.

5. A healthcare provider is assessing a client who is receiving treatment for dehydration. Which assessment finding indicates that the client is responding to the treatment?

• A. Dry mucous membranes
• B. Increased urine output
• C. Decreased skin turgor
• D. Elevated heart rate

Correct answer: B

Rationale: Increased urine output is a positive sign indicating that the client is responding to the treatment for dehydration. It suggests that the client's kidneys are functioning better, helping to eliminate excess fluid and waste products from the body. Dry mucous membranes (Choice A) are a sign of dehydration, not improvement. Decreased skin turgor (Choice C) and elevated heart rate (Choice D) are also symptoms of dehydration and do not indicate a positive response to treatment.
