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 untreated pneumonia?

• A. Sepsis and respiratory failure
• B. Heart failure and kidney failure
• C. Pulmonary embolism and electrolyte imbalance
• D. Liver failure and electrolyte imbalance

Correct answer: A

Rationale: The correct answer is A: Sepsis and respiratory failure. Untreated pneumonia can lead to severe complications such as sepsis, which is a life-threatening response to infection, and respiratory failure, where the lungs can no longer provide enough oxygen to the body. Heart failure and kidney failure (choice B) are not direct complications of untreated pneumonia. Pulmonary embolism and electrolyte imbalance (choice C) are also not commonly associated with untreated pneumonia. Liver failure and electrolyte imbalance (choice D) are not typical complications of pneumonia.

3. A nurse is reinforcing discharge teaching with a client who is postoperative following an open radical prostatectomy. Which of the following instructions should the nurse include in the teaching?

• A. Perform Kegel exercises daily
• B. Perform light exercise for 3 hours each day
• C. Avoid bathing for 3 days
• D. Avoid sitting in a chair for more than 2 hours

Correct answer: A

Rationale: The correct answer is A: Perform Kegel exercises daily. After a radical prostatectomy, Kegel exercises are beneficial as they help strengthen the pelvic floor muscles, aiding in urinary control and recovery. Choice B is incorrect because recommending 3 hours of light exercise daily may not be suitable immediately postoperatively. Choice C is incorrect as personal hygiene, including bathing, is important for postoperative care. Choice D is incorrect because sitting for more than 2 hours does not specifically relate to the client's postoperative care needs.

4. A client with diabetes mellitus is experiencing hypoglycemia. Which of the following actions should the nurse take?

• A. Administer insulin
• B. Administer glucagon
• C. Administer 4 oz of orange juice
• D. Administer 1 L of water

Correct answer: C

Rationale: Administering 4 oz of orange juice is the appropriate action for a client experiencing hypoglycemia due to diabetes mellitus. Orange juice contains simple sugars that can quickly raise blood glucose levels. Insulin (Choice A) would further lower blood sugar, worsening the condition. Glucagon (Choice B) is used in severe hypoglycemia when the client cannot take anything by mouth. Administering 1 L of water (Choice D) is not indicated in hypoglycemia treatment; the priority is to raise blood sugar levels. Therefore, the correct choice is to administer orange juice to address the low blood sugar in this situation.

5. What is the priority for a client with dehydration?

• A. Administer antiemetics to prevent nausea
• B. Monitor electrolyte levels to prevent imbalances
• C. Administer oral rehydration solutions
• D. Administer intravenous fluids

Correct answer: B

Rationale: The priority for a client with dehydration is to monitor electrolyte levels to prevent imbalances. Dehydration can lead to electrolyte disturbances, which can have serious consequences. Administering antiemetics (Choice A) may help with nausea but does not address the root cause of dehydration. Administering oral rehydration solutions (Choice C) can be beneficial, but monitoring electrolyte levels is crucial in managing dehydration. Administering intravenous fluids (Choice D) is important in severe cases of dehydration, but monitoring electrolytes should come first to assess the extent of the imbalance and guide fluid replacement therapy effectively.
