Nursing Elites

1. A client's chest tube insertion site has crepitus (crackling sensation) upon palpation. What is the nurse's next step?

• A. Apply a pressure dressing to the chest tube site.
• B. Administer an oral antihistamine.
• C. Assess the client for allergies to cleaning agents.
• D. Measure the area of swelling and crackling.

Correct answer: D

Rationale: The correct next step for the nurse is to measure the area of crepitus. Crepitus indicates subcutaneous emphysema, which is a serious condition requiring monitoring. Applying a pressure dressing (Choice A) could worsen the condition by trapping air under the skin. Administering an oral antihistamine (Choice B) is not indicated for crepitus. Assessing for allergies to cleaning agents (Choice C) is not the priority when dealing with crepitus and subcutaneous emphysema.

2. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

3. A client with a ruptured spleen underwent an emergency splenectomy. Twelve hours later, the client’s urine output is 25 ml/hour. What is the most likely cause?

• A. This is a normal finding after surgery.
• B. Oliguria signals tubular necrosis related to hypoperfusion.
• C. Oliguria signals dehydration and fluid loss.
• D. Urine output of 25 ml/hour is an expected finding after splenectomy.

Correct answer: B

Rationale: Oliguria, or decreased urine output, after surgery can indicate tubular necrosis due to hypoperfusion, which may require intervention to restore renal function. Choice A is incorrect as oliguria is not a normal finding after surgery. Choice C is incorrect because dehydration is less likely in this context compared to tubular necrosis. Choice D is incorrect as a urine output of 25 ml/hour is not expected after splenectomy and should raise concern for renal impairment.

4. 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.

5. A client with deep vein thrombosis (DVT) is prescribed heparin therapy. What laboratory value should the nurse monitor?

• A. Monitor the client’s liver function tests.
• B. Monitor the client’s prothrombin time (PT).
• C. Monitor the client’s partial thromboplastin time (PTT).
• D. Monitor the client’s red blood cell count.

Correct answer: C

Rationale: The correct answer is C: Monitor the client’s partial thromboplastin time (PTT). During heparin therapy for DVT, it is essential to monitor the PTT to assess the effectiveness of the medication in preventing clot formation. Monitoring the PTT helps ensure that the client is within the therapeutic range for anticoagulation. Choices A, B, and D are incorrect because liver function tests, prothrombin time (PT), and red blood cell count are not specifically monitored to assess the effectiveness of heparin therapy in preventing clot formation.
