Nursing Elites

1. A male client admitted three days ago with respiratory failure is intubated, and 40% oxygen per facemask is initiated. Currently, his temperature is 99°F, capillary refill is less than 4 seconds, and respiratory effort is within normal limits. What outcome should the nurse evaluate to measure for successful extubation?

• A. Exhibits adequate tissue perfusion
• B. Remains free of injury
• C. Remains free of infection
• D. Maintains effective breathing pattern

Correct answer: D

Rationale: Successful extubation relies on the patient's ability to maintain an effective breathing pattern. This indicates that the patient can adequately oxygenate and ventilate without the need for mechanical support. Monitoring tissue perfusion, preventing infection, and ensuring safety are important but not directly related to the immediate criteria for successful extubation. Tissue perfusion, injury prevention, and infection control are crucial aspects of overall patient care but are not the primary factors to consider when evaluating readiness for extubation.

2. The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Activated partial thromboplastin time (aPTT)

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). While INR is commonly used to monitor the effectiveness of warfarin therapy, in the case of heparin therapy, the Partial Thromboplastin Time (PTT) is the preferred test. Choice A, Prothrombin Time (PT), measures the activity of the extrinsic pathway of coagulation and is not the best choice for monitoring heparin therapy. Choice D, Activated Partial Thromboplastin Time (aPTT), is similar to PTT and is used to monitor heparin therapy, but PTT is the more specific test. Therefore, monitoring PTT is crucial in determining the effectiveness and safety of heparin therapy.

3. A client in the oliguric phase of acute renal failure (ARF) has a 24-hour urine output of 400 ml. How much oral intake should the nurse allow this client to have during the next 24 hours?

• A. Encourage oral fluids as tolerated
• B. Decrease oral intake to 200 ml
• C. Allow the client to have exactly 400 ml oral intake
• D. Limit oral intake to 900 to 1,000 ml

Correct answer: D

Rationale: In the oliguric phase of acute renal failure (ARF), the goal is to prevent fluid overload. Since the client has a low urine output of 400 ml in 24 hours, limiting oral intake to 900 to 1,000 ml is appropriate. Encouraging unrestricted oral fluids (Choice A) can exacerbate fluid overload. Decreasing oral intake to 200 ml (Choice B) would be too restrictive and may lead to dehydration. Allowing the client to have exactly 400 ml oral intake (Choice C) would not account for other sources of fluid intake and output, potentially resulting in fluid imbalance.

4. While teaching a group of adults about health promotion activities, a nurse identifies a behavior that poses the most significant risk factor for the development of skin cancer. Which behavior should the nurse address?

• A. Consuming a high-fat diet
• B. Using tanning beds
• C. Smoking cigarettes
• D. Drinking alcohol

Correct answer: B

Rationale: Using tanning beds is the most significant risk factor for developing skin cancer. Ultraviolet (UV) radiation from tanning beds damages the skin and increases the risk of skin cancer. Consuming a high-fat diet, smoking cigarettes, and drinking alcohol are unhealthy behaviors but are not directly linked to the development of skin cancer like UV exposure from tanning beds.

5. The nurse is planning care for a 2-year-old child who is scheduled for an infusion of immune globulin for treatment of idiopathic thrombocytopenic purpura (ITP). Which nursing diagnosis has the highest priority for this child?

• A. Risk for infection
• B. Risk for injury
• C. Altered oral mucous membranes
• D. Risk for fluid volume deficit

Correct answer: A

Rationale: The correct answer is 'Risk for infection.' When caring for a child with ITP scheduled for immune globulin infusion, the highest priority is to prevent infection. This is crucial due to the risk of bleeding associated with ITP and the immunosuppression that can be caused by the condition and its treatment. The other options, such as 'Risk for injury,' 'Altered oral mucous membranes,' and 'Risk for fluid volume deficit,' are not as high a priority as preventing infection in this particular situation.
