1. What are the complications of untreated deep vein thrombosis (DVT)?

A. Pulmonary embolism and stroke
B. Kidney failure and hypertension
C. Liver failure and electrolyte imbalance
D. Fluid overload and bradycardia

Correct answer: A

Rationale: Corrected Rationale: Untreated DVT can lead to complications such as pulmonary embolism and stroke. Pulmonary embolism occurs when a blood clot from the leg travels to the lungs, potentially blocking blood flow and causing respiratory distress. Stroke can occur if a blood clot dislodges from the leg veins, travels to the brain, and obstructs a blood vessel, leading to brain tissue damage. Both of these complications are life-threatening if not managed promptly. The other choices (B, C, D) do not represent common complications of untreated DVT and are therefore incorrect.

2. A nurse manager is discussing the responsibility of nurses caring for clients who have Clostridium difficile. Which of the following information should the nurse include in the teaching?

A. Assign the client to a room with a negative air-flow system
B. Use alcohol-based hand sanitizer when leaving the client's room
C. Clean contaminated surfaces in the client's room with a phenol solution
D. Have family members wear a gown and gloves when visiting

Correct answer: D

Rationale: The correct answer is D because having family members wear a gown and gloves when visiting a client with Clostridium difficile is essential to prevent the spread of infection. Options A, B, and C are incorrect. Negative air-flow systems are not necessary for preventing the spread of C. difficile. While alcohol-based hand sanitizers are effective for routine hand hygiene, they may not be sufficient for C. difficile. Cleaning contaminated surfaces with a phenol solution is not the most effective method for preventing the spread of C. difficile, as spores can be resistant to many disinfectants.

3. A nurse is reviewing the plan of care for a client who is receiving oxygen therapy. Which of the following interventions should the nurse include to prevent complications?

A. Check the client's oxygen saturation every 2 hours
B. Provide humidified oxygen
C. Instruct the client to perform deep breathing exercises
D. Use an oxygen mask for delivery

Correct answer: B

Rationale: The correct answer is B: Provide humidified oxygen. Providing humidified oxygen helps prevent dryness and irritation of the respiratory tract during oxygen therapy. This intervention is crucial in preventing complications such as mucous membrane dryness and potential damage to the airways. Checking the client's oxygen saturation every 2 hours (choice A) is essential for monitoring the client's response to therapy but does not directly prevent complications. Instructing the client to perform deep breathing exercises (choice C) is beneficial for respiratory function but does not directly address preventing complications related to oxygen therapy. Using an oxygen mask for delivery (choice D) is a common method of administering oxygen but does not specifically focus on preventing complications like dryness and irritation.

4. A healthcare provider is reviewing the medical record of a client who is scheduled for surgery. Which of the following findings should the provider report?

A. White blood cell count of 8,000/mm³
B. Potassium level of 4.0 mEq/L
C. Creatinine level of 1.0 mg/dL
D. Hemoglobin level of 12 g/dL

Correct answer: C

Rationale: An elevated creatinine level indicates impaired kidney function, which may affect the client's ability to undergo surgery. The other laboratory values (white blood cell count, potassium level, and hemoglobin level) are within normal ranges and do not directly impact the client's readiness for surgery.

5. What are the key differences between hypoglycemia and hyperglycemia?

A. Hypoglycemia: Sweating, trembling; Hyperglycemia: Frequent urination, thirst
B. Hypoglycemia: Increased thirst; Hyperglycemia: Sweating, confusion
C. Hypoglycemia: Increased appetite; Hyperglycemia: Blurred vision
D. Hypoglycemia: Dizziness; Hyperglycemia: Low blood pressure

Correct answer: A

Rationale: Hypoglycemia typically presents with sweating and trembling, while hyperglycemia is characterized by frequent urination and thirst. Therefore, the correct key differences between hypoglycemia and hyperglycemia are that hypoglycemia includes symptoms like sweating and trembling, while hyperglycemia involves symptoms such as frequent urination and thirst. Choices B, C, and D are incorrect because they do not accurately represent the characteristic symptoms of hypoglycemia and hyperglycemia, as stated in the question.
