Nursing Elites

1. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

2. What are the complications of diabetic ketoacidosis?

• A. Electrolyte imbalance and dehydration
• B. Hypoglycemia and increased urination
• C. Kidney failure and respiratory distress
• D. Liver failure and hypertension

Correct answer: A

Rationale: The correct answer is A: Electrolyte imbalance and dehydration. Diabetic ketoacidosis can lead to imbalances in electrolytes such as potassium, sodium, and chloride, as well as dehydration due to excess urination and vomiting. These complications should be managed promptly with appropriate fluids and insulin. Choices B, C, and D are incorrect. Hypoglycemia and increased urination are not typical complications of diabetic ketoacidosis; kidney failure and respiratory distress may occur in severe cases but are not the primary complications. Liver failure and hypertension are not directly associated with diabetic ketoacidosis.

3. What are the risk factors for pressure ulcer development?

• A. Immobility and poor nutrition
• B. Obesity and diabetes
• C. Dehydration and malnutrition
• D. Use of assistive devices and prolonged bedrest

Correct answer: A

Rationale: Corrected Rationale: The correct answer is immobility and poor nutrition. Immobility can lead to constant pressure on certain areas of the body, while poor nutrition can impair tissue repair and regeneration, both contributing to the development of pressure ulcers. Choices B, C, and D are incorrect because while obesity, diabetes, dehydration, malnutrition, use of assistive devices, and prolonged bedrest can impact skin integrity and wound healing, they are not the primary risk factors specifically associated with pressure ulcer development.

4. What are the early signs and symptoms of sepsis?

• A. Increased heart rate and fever
• B. Low blood pressure and confusion
• C. Rapid breathing and sweating
• D. Abdominal pain and cyanosis

Correct answer: A

Rationale: The correct answer is A: Increased heart rate and fever. In sepsis, an increased heart rate and fever are common early signs of systemic infection. While choices B, C, and D can be present in later stages of sepsis, they are not typically the initial signs. Low blood pressure and confusion may occur in severe sepsis or septic shock. Rapid breathing and sweating can be seen as sepsis progresses. Abdominal pain and cyanosis may develop as the condition advances but are not usually the earliest signs.

5. A nurse is planning care for a client who is at 28 weeks of gestation and has preeclampsia. Which of the following interventions should the nurse include in the plan?

• A. Restrict the client's fluid intake.
• B. Monitor the client's deep-tendon reflexes.
• C. Place the client in the lithotomy position.
• D. Encourage the client to ambulate frequently.

Correct answer: B

Rationale: The correct answer is to monitor the client's deep-tendon reflexes. Monitoring deep-tendon reflexes is crucial in clients with preeclampsia as hyperreflexia can indicate severe complications. Restricting the client's fluid intake is not recommended as hydration is essential. Placing the client in the lithotomy position can worsen preeclampsia by reducing blood flow to the heart, so it should be avoided. Encouraging the client to ambulate frequently may not be suitable for a client with preeclampsia due to the risk of falls and increased stress on the body.
