Correct Answer: A

Rationale: Assessing mobility should be the nurse's priority as it ensures the client's safety and helps in developing an appropriate care plan. By evaluating the client's ability to move after the knee arthroplasty, the nurse can identify any immediate issues or complications that need to be addressed promptly. Monitoring vital signs, providing pain relief, and reinforcing discharge teaching are important aspects of care but assessing mobility takes precedence in ensuring the client's immediate well-being and identifying any potential risks.

Correct Answer: A

Rationale: When assessing a patient with suspected stroke symptoms, it is crucial to check for facial drooping as it can be a sign of facial nerve weakness, which is a common indicator of stroke. While monitoring speech difficulties and evaluating arm weakness are also important assessments in stroke cases, they are secondary to facial drooping. Checking for the time of onset of symptoms is essential to determine eligibility for time-sensitive treatments like thrombolytic therapy, but when prioritizing assessments, facial drooping takes precedence.

Correct Answer: A

Rationale: Corrected Question: To assess and manage a patient with anemia, monitoring hemoglobin levels and providing iron supplements are crucial. Anemia is commonly caused by iron deficiency, making iron supplementation a cornerstone of treatment. B12 injections (Choice B) are more relevant for treating megaloblastic anemia, not the typical iron-deficiency anemia. Monitoring for signs of infection and administering folic acid (Choice C) are important in specific types of anemia like megaloblastic anemia, but not the first-line approach for anemia management. Administering oxygen therapy (Choice D) is not the primary intervention for anemia unless severe hypoxemia is present, which is not typically seen in anemia.

Correct Answer: B

Rationale: Hypervigilance is a common manifestation of PTSD characterized by heightened alertness and fear of danger. This heightened state of awareness can lead to irritability, difficulty concentrating, and sleep disturbances. Choices A, C, and D are incorrect. Hyperactivity is not typically associated with PTSD; restlessness may be present but is not the primary manifestation, and avoidance of social situations is more commonly seen in conditions like social anxiety disorder rather than PTSD.

Correct Answer: C

Rationale: When signs of phlebitis are observed in a client receiving IV fluids, the appropriate action is to apply a warm compress. This helps to reduce discomfort and swelling at the site of the IV insertion. Applying a cold compress may not be as effective in this case and could potentially worsen the condition. While notifying the physician is important, providing immediate comfort to the client through a warm compress is the initial recommended intervention. Administering anti-inflammatory medication should only be done under the direction of a healthcare provider after assessment and evaluation of the client's condition.
