Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

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

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who has been experiencing increasing shortness of breath. Which finding requires immediate intervention?

• A. A respiratory rate of 26 breaths per minute
• B. Use of accessory muscles for breathing
• C. Barrel chest appearance
• D. A pulse oximetry reading of 88%

Correct answer: D

Rationale: A pulse oximetry reading of 88% indicates hypoxemia, which requires immediate intervention to improve oxygenation. Hypoxemia can lead to serious complications if not addressed promptly. While a respiratory rate of 26 breaths per minute and the use of accessory muscles for breathing are concerning in COPD, they do not indicate an immediate life-threatening situation. Similarly, a barrel chest appearance is a common finding in COPD and does not require urgent intervention compared to the critical need to address hypoxemia.

3. A client is admitted with diabetic ketoacidosis (DKA). Which laboratory result would the nurse expect to find in this client?

• A. pH level of 7.45
• B. Serum calcium of 15 mg/dL
• C. Blood glucose of 450 mg/dL
• D. Sodium level of 120 mEq/L

Correct answer: C

Rationale: Clients with diabetic ketoacidosis typically present with elevated blood glucose levels, often above 300 mg/dL. This high blood glucose level, along with other symptoms, helps confirm the diagnosis of DKA. A pH level of 7.45 would be indicative of alkalosis, not the acidosis seen in DKA. A serum calcium level of 15 mg/dL is significantly elevated and is not a typical finding in DKA. A sodium level of 120 mEq/L indicates hyponatremia, which is not a characteristic laboratory finding in DKA.

4. A client on mechanical ventilation is experiencing high-pressure alarms. What action should the nurse implement first?

• A. Check the client's oxygen saturation.
• B. Assess the client's endotracheal tube for obstruction.
• C. Reposition the client to relieve pressure.
• D. Suction the client's airway.

Correct answer: B

Rationale: The correct answer is to assess the client's endotracheal tube for obstruction. When a client on mechanical ventilation experiences high-pressure alarms, the first action should be to check for any potential obstructions in the airway, which can trigger the alarms. Checking the oxygen saturation (Choice A) is important but not the priority when dealing with high-pressure alarms. Repositioning the client (Choice C) may be necessary later but should not be the initial action. Suctioning the client's airway (Choice D) should only be done after assessing for and addressing any obstructions in the endotracheal tube.

5. A client undergoing chemotherapy reports extreme fatigue. What should the nurse recommend to manage this symptom?

• A. Increase the dose of chemotherapy.
• B. Rest when needed and maintain a balanced diet.
• C. Perform light physical activity to reduce fatigue.
• D. Consider delaying the chemotherapy treatment.

Correct answer: B

Rationale: The correct recommendation for managing chemotherapy-induced fatigue is to advise the client to rest when needed and maintain a balanced diet. Increasing the dose of chemotherapy (Choice A) would exacerbate the fatigue and other side effects. While light physical activity (Choice C) can be beneficial, extreme fatigue may require more rest initially. Delaying chemotherapy treatment (Choice D) should only be considered after consultation with the healthcare provider, as timely treatment is usually crucial in cancer care.
