WGU Pathophysiology Final Exam
1. Prior to leaving on a backpacking trip to Southeast Asia, a college student has received a tetanus booster shot. This immunization confers protection by way of what immune process?
- A. Passive natural immunity
- B. Active natural immunity
- C. Passive artificial immunity
- D. Active artificial immunity
Correct answer: D
Rationale: The correct answer is D: Active artificial immunity. A tetanus booster shot confers protection through active artificial immunity. Active immunity involves the body producing its antibodies in response to an antigen, providing long-lasting protection. In this case, the tetanus booster shot triggers the student's immune system to produce specific antibodies against tetanus toxins. Choices A, B, and C are incorrect because passive immunity does not involve the individual's immune system producing antibodies; instead, it involves the direct transfer of antibodies from another source (natural or artificial) for immediate, but temporary, protection.
2. In the traditional rating scale, what is the time period typically used for evaluation?
- A. Twelve months
- B. Six months
- C. Three months
- D. One month
Correct answer: A
Rationale: In the traditional rating scale, evaluations are typically conducted over a 12-month period. This duration allows for a comprehensive assessment of the employee's performance and progress throughout the year, capturing a broader range of experiences and accomplishments to provide a more holistic evaluation. Choices B, C, and D are incorrect because they do not align with the standard practice of conducting annual evaluations in a traditional rating scale setting.
3. After a few hours in the Emergency Room, Mr. Dizon is admitted to the ward with an order of hourly monitoring of blood pressure. The nurse finds that the cuff is too narrow and this will cause the blood pressure reading to be:
- A. inconsistent
- B. low systolic and high diastolic
- C. higher than what the reading should be
- D. lower than what the reading should be
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
4. A patient on long-term steroid therapy should be monitored for which condition?
- A. Hyperglycemia
- B. Hypothyroidism
- C. Hypertension
- D. Osteoporosis
Correct answer: D
Rationale: Corrected Rationale: Patients on long-term steroid therapy should be monitored for osteoporosis due to the medication's potential to decrease bone density. Choices A, B, and C are incorrect. While long-term steroid therapy can also lead to hyperglycemia, hypothyroidism, and hypertension, the primary concern and most common risk associated with prolonged steroid use is osteoporosis.
5. What observation by the nurse indicates the need for further teaching to unlicensed assistive personnel (UAP) on assisting with ambulation?
- A. The UAP puts shoes on the client
- B. The UAP removes floor rugs and loose objects from the path
- C. The UAP walks to the side and slightly in front of the client
- D. The UAP uses a transfer (gait) belt
Correct answer: C
Rationale: Choice C is the correct answer because the UAP should walk slightly behind or to the side of the client, not in front, to provide proper support during ambulation. Choices A, B, and D are not indicative of incorrect technique or the need for further teaching. Putting shoes on the client, removing floor rugs and loose objects, and using a transfer (gait) belt are all appropriate actions when assisting with ambulation.
