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. A healthcare professional is collecting data from a client who has iron deficiency anemia. Which of the following findings should the healthcare professional expect?

• A. Increased energy
• B. Easy bruising
• C. Pale conjunctiva
• D. Weight gain

Correct answer: C

Rationale: Pale conjunctiva is a common sign of iron deficiency anemia due to reduced hemoglobin levels. This results in decreased oxygen-carrying capacity, leading to tissue hypoxia and pallor. 'Increased energy' (choice A) is not typically associated with iron deficiency anemia, as fatigue and weakness are common symptoms. 'Easy bruising' (choice B) is more characteristic of platelet disorders or vitamin deficiencies rather than iron deficiency anemia. 'Weight gain' (choice D) is not a typical finding in iron deficiency anemia; in fact, weight loss is more common due to decreased appetite and overall weakness.

3. A nurse is reviewing the medical record of a client who has diabetes mellitus and is receiving insulin. Which of the following findings should the nurse report to the provider?

• A. Hemoglobin A1c of 6%
• B. Fasting blood glucose of 90 mg/dL
• C. Blood glucose of 200 mg/dL
• D. Blood glucose of 100 mg/dL

Correct answer: C

Rationale: A blood glucose level of 200 mg/dL indicates hyperglycemia and should be reported for potential insulin adjustment.

4. What are the signs and symptoms of a pulmonary embolism?

• A. Sudden shortness of breath
• B. Chest pain
• C. Cough with blood
• D. All of the above

Correct answer: D

Rationale: A pulmonary embolism can manifest with sudden shortness of breath, chest pain, and coughing up blood. These symptoms are classic presentations of a pulmonary embolism due to the blockage of blood flow to the lungs. Therefore, the correct answer is 'All of the above.' Each symptom alone can be seen in various other conditions, but when occurring together, they strongly suggest a pulmonary embolism. Sudden shortness of breath is due to decreased oxygenation, chest pain can result from the strain on the heart, and coughing with blood may indicate damage to the lung tissue. Choosing any single symptom would not encompass the full range of presentations seen in a pulmonary embolism.

5. Which of the following findings indicates a need for immediate attention in a client diagnosed with delirium?

• A. Confusion and disorientation that resolve with rest
• B. A blood pressure reading of 110/70
• C. Irritability and agitation that worsen throughout the day
• D. Mild confusion during the evening hours

Correct answer: C

Rationale: The correct answer is C: Irritability and agitation that worsen throughout the day. These symptoms are concerning in a client diagnosed with delirium as they may indicate an exacerbation of the condition or an underlying cause that requires immediate attention. Option A describes symptoms that resolve with rest, which may not be as urgent. Option B provides a normal blood pressure reading, which is not typically associated with immediate attention in delirium cases. Option D describes mild confusion during specific hours, which may not be as critical as worsening symptoms throughout the day.
