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. A client with a history of hypertension is prescribed enalapril (Vasotec). Which statement by the client indicates a need for further teaching?

• A. I will monitor my blood pressure regularly.
• B. I will report any signs of infection to my healthcare provider.
• C. I will avoid using salt substitutes.
• D. I will increase my intake of potassium-rich foods.

Correct answer: D

Rationale: The correct answer is D. Increasing potassium intake can lead to hyperkalemia, especially in clients taking ACE inhibitors like enalapril. Hyperkalemia is a potential side effect of ACE inhibitors and can be exacerbated by consuming potassium-rich foods. Monitoring blood pressure regularly (A) is important when taking antihypertensive medications. Reporting signs of infection (B) is crucial as ACE inhibitors can lower the immune response. Avoiding salt substitutes (C) is necessary because they may contain potassium chloride, leading to increased potassium levels, which can be harmful in combination with ACE inhibitors.

3. A community health nurse is conducting a neighborhood discussion group about disaster planning. What information regarding transmission of anthrax should the nurse provide to the group?

• A. Infection is acquired when anthrax spores enter a host.
• B. Mature anthrax bacteria live dormant on inanimate objects.
• C. Spores cannot survive for extended periods outside a living host.
• D. Anthrax is transmitted by respiratory droplets from person to person.

Correct answer: A

Rationale: The correct answer is A: Infection is acquired when anthrax spores enter a host. Anthrax is primarily transmitted through spores entering the body, either through the skin, inhalation, or ingestion. Person-to-person transmission of anthrax is extremely rare and not a significant mode of transmission. Choices B and C are incorrect because mature anthrax bacteria do not live dormant on inanimate objects, and spores can survive for extended periods outside a living host. Choice D is incorrect as anthrax is not transmitted by respiratory droplets from person to person.

4. The healthcare provider is assessing a client with chronic obstructive pulmonary disease (COPD). Which finding requires immediate intervention?

• A. Oxygen saturation of 88%.
• B. Use of accessory muscles for breathing.
• C. Respiratory rate of 26 breaths per minute.
• D. Barrel-shaped chest.

Correct answer: C

Rationale: A respiratory rate of 26 breaths per minute is an abnormal finding and indicates that the client is experiencing respiratory distress, requiring immediate intervention. This rapid respiratory rate can signify inadequate oxygenation and ventilation. Oxygen saturation of 88% is low but not as immediately concerning as a high respiratory rate, which indicates the body is compensating for respiratory distress. The use of accessory muscles for breathing and a barrel-shaped chest are typical findings in clients with COPD but do not indicate an immediate need for intervention as they are more chronic in nature and may be seen in stable COPD patients.

5. During a home visit, the nurse observes an elderly client with disabilities slip and fall. What action should the nurse take first?

• A. provide the client with 4 ounces of orange juice
• B. call 911 to summon emergency assistance
• C. check the client for lacerations or fractures
• D. assess the client's blood sugar level

Correct answer: C

Rationale: The correct action for the nurse to take first after an elderly client with disabilities slips and falls is to check the client for lacerations or fractures. This is crucial to assess the extent of injuries and provide appropriate medical attention promptly. Option A, providing orange juice, is not a priority in this situation and does not address the potential injuries. While calling 911 (Option B) may be necessary, assessing for immediate injuries takes precedence. Assessing the client's blood sugar level (Option D) is not the immediate priority after a fall unless there is a specific indication or suspicion of hypoglycemia.
