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 is the most important intervention for a client with delirium?

• A. Administer sedative medication
• B. Identify any reversible causes of delirium
• C. Provide a low-stimulation environment
• D. Increase environmental stimulation

Correct answer: B

Rationale: The correct answer is to identify any reversible causes of delirium. Delirium can be caused by various factors such as infections, medications, or metabolic imbalances. Addressing these underlying causes can help resolve delirium. Administering sedative medication (Choice A) can worsen delirium by further altering mental status. Providing a low-stimulation environment (Choice C) is helpful to manage delirium symptoms, but it is not the most important intervention. Increasing environmental stimulation (Choice D) is contraindicated in delirium as it can exacerbate confusion and agitation.

3. What are the signs and symptoms of hyperkalemia and how should it be managed?

• A. Muscle weakness and cardiac arrhythmias; administer calcium gluconate
• B. Confusion and bradycardia; administer insulin and glucose
• C. Fatigue and irregular heart rate; administer diuretics
• D. Nausea and vomiting; administer sodium bicarbonate

Correct answer: A

Rationale: The signs and symptoms of hyperkalemia include muscle weakness and cardiac arrhythmias, making choice A correct. Hyperkalemia can lead to dangerous cardiac effects, and calcium gluconate is used to stabilize the heart by antagonizing the effects of potassium. Choices B, C, and D describe symptoms and interventions that are not typically associated with hyperkalemia. Confusion and bradycardia are not common in hyperkalemia, and insulin and glucose are used in hyperkalemia only under specific circumstances. Fatigue and irregular heart rate are vague symptoms, and diuretics are not the primary treatment for hyperkalemia. Nausea and vomiting are nonspecific symptoms and sodium bicarbonate is not indicated for the management of hyperkalemia.

4. What are the early signs of sepsis in a patient?

• A. Increased heart rate and fever
• B. Low blood pressure and confusion
• C. Elevated blood sugar and sweating
• D. Increased urine output and abdominal pain

Correct answer: A

Rationale: The correct answer is A: Increased heart rate and fever. These are early signs of sepsis and indicate a systemic infection. It is crucial to identify these signs promptly to initiate appropriate treatment. Choice B is incorrect because low blood pressure and confusion are more indicative of severe sepsis or septic shock rather than early signs. Choice C is incorrect as elevated blood sugar and sweating are not typical early signs of sepsis. Choice D is also incorrect as increased urine output and abdominal pain are not early signs of sepsis.

5. How should a healthcare provider assess and manage a patient with a suspected urinary tract infection (UTI)?

• A. Antibiotic Therapy
• B. Hydration
• C. Pain Management
• D. Patient Education

Correct answer: A

Rationale: When assessing and managing a patient with a suspected UTI, the priority is to start antibiotic therapy to treat the infection. Antibiotics are crucial in eliminating the bacteria causing the UTI. While hydration is important to help flush out the bacteria, pain management can help alleviate discomfort but is not the primary treatment. Patient education is vital for prevention and management but is not the immediate intervention required for a suspected UTI.
