Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. The healthcare provider is caring for a client with diabetes insipidus. Which finding indicates that the treatment is effective?

• A. Urine output is decreased.
• B. Thirst is decreased.
• C. Weight loss is observed.
• D. Urine specific gravity is within the normal range.

Correct answer: D

Rationale: In diabetes insipidus, the body loses excessive amounts of water, leading to diluted urine with low specific gravity. Therefore, when the urine specific gravity is within the normal range, it indicates that the kidneys are properly concentrating urine, which is a sign of effective treatment for diabetes insipidus. Choices A, B, and C are incorrect because in diabetes insipidus, there is polyuria (excessive urination), persistent thirst due to fluid loss, and potential weight loss due to fluid imbalance, so these findings would not indicate effective treatment.

3. The public health nurse is creating a plan to increase state funding for a local health clinic. Which strategy is likely to be most effective in obtaining funding for the clinic?

• A. Run the health clinic economically and promote the services the clinic provides.
• B. Organize concerned citizens to write letters and call state representatives.
• C. Highlight to the media the valuable services offered by the community clinic.
• D. Hire a professional lobbyist to convince Congress of the local clinic's value.

Correct answer: B

Rationale: Organizing concerned citizens to contact state representatives is likely the most effective strategy to secure state funding for the local health clinic. By mobilizing a group of citizens who are directly impacted by the clinic's services, the public health nurse can create a strong advocacy group that can influence decision-makers. Option A, running the health clinic economically and promoting its services, may be necessary but does not directly address the funding aspect. Option C, highlighting services to the media, may raise awareness but does not guarantee funding. Option D, hiring a professional lobbyist, may be costly and may not have the same grassroots impact as organizing citizens.

4. The nurse is caring for a client with cirrhosis of the liver. Which laboratory result requires immediate intervention?

• A. Serum albumin of 3.5 g/dL.
• B. Prothrombin time (PT) of 12 seconds.
• C. Hemoglobin of 10 g/dL.
• D. Serum ammonia level of 180 mcg/dL.

Correct answer: D

Rationale: The correct answer is D, the serum ammonia level of 180 mcg/dL. An elevated serum ammonia level indicates hepatic dysfunction and can lead to hepatic encephalopathy, which is a medical emergency requiring immediate intervention. Options A, B, and C are within normal ranges or slightly abnormal values for clients with cirrhosis and do not pose an immediate threat. Serum albumin levels may indicate malnutrition, prothrombin time may reflect liver synthetic function, and hemoglobin levels can be affected by various factors but do not require immediate intervention in this scenario.

5. A client who has active tuberculosis (TB) is admitted to the medical unit. What action is most important for the nurse to implement?

• A. Wear a gown and gloves.
• B. Have the client wear a mask.
• C. Perform hand hygiene.
• D. Assign the client to a negative air-flow room.

Correct answer: D

Rationale: The correct answer is to assign the client to a negative air-flow room (Choice D). Active tuberculosis requires implementation of airborne precautions, including isolating the client in a negative pressure air-flow room to prevent the spread of the infection to others. Choice A (Wear a gown and gloves) is important for standard precautions but does not address the specific airborne precautions needed for tuberculosis. Choice B (Have the client wear a mask) may help reduce the spread of respiratory droplets but does not provide adequate protection for healthcare workers or other patients. Choice C (Perform hand hygiene) is essential for infection control but is not the most critical action when dealing with an airborne infection like tuberculosis.
