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

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 charge nurse in a long-term care facility notices an assistive personnel's (AP) repeated failure to provide oral care for clients. Which of the following actions should the charge nurse take?

Correct answer: D

Rationale: When a charge nurse observes repeated failure in a staff member's performance, it is essential to address the issue directly. Choice D is the correct answer as it involves discussing the behavior with the assistive personnel (AP) while reinforcing expectations. This approach helps in clarifying the expected standards, setting accountability, and providing an opportunity for improvement. Choices A, B, and C are incorrect. Ignoring the behavior (Choice A) does not address the problem and can lead to continued substandard care. Reassigning the AP (Choice B) may not solve the issue and can potentially transfer the problem to another area. Reporting the behavior to the manager (Choice C) without directly addressing it with the AP first may not promote a constructive approach to resolving the issue.

3. A nurse is reviewing the medical record of a client who has schizophrenia and is taking clozapine. Which of the following findings should the nurse identify as a contraindication to the administration of clozapine?

Correct answer: A

Rationale: A WBC count of 2,900/mm3 indicates leukopenia, which is a serious side effect of clozapine and contraindicates its use. Leukopenia is a significant concern with clozapine therapy due to the risk of agranulocytosis, a potentially life-threatening condition. Monitoring the WBC count is crucial to detect this adverse effect early. The other options (B, C, and D) are within normal ranges and not contraindications for administering clozapine.

4. A 23-year-old woman at 32-weeks gestation is seen in the outpatient clinic. Which of the following findings, if assessed by the nurse, would indicate a possible complication?

Correct answer: A

Rationale: The correct answer is A. Positive urine glucose and acetone could indicate gestational diabetes or preeclampsia, both of which are complications. Choice B, pedal edema, is common in pregnancy but may also be a sign of preeclampsia if severe. Choice C, an increase in vaginal discharge, is a normal finding in pregnancy due to hormonal changes. Choice D, pressure against the diaphragm when the baby moves, is a normal sensation due to the growing uterus displacing abdominal contents.

5. What is the priority for the nurse when caring for a patient with a chest tube?

Correct answer: A

Rationale: The priority for the nurse when caring for a patient with a chest tube is to ensure tube patency and observe for air leaks. This is essential to prevent complications such as pneumothorax and ensure the patient's lung function. While maintaining sterile technique during dressing changes, monitoring drainage, recording output, and observing for signs of infection and subcutaneous emphysema are also important, ensuring tube patency takes precedence as it directly impacts the patient's respiratory status and overall safety.
