A nurse is caring for a client who is experiencing post-traumatic stress disorder (PTSD). Which of the following manifestations should the nurse expect?

Correct Answer: B

Rationale: The correct answer is B: Hypervigilance. Individuals with PTSD often experience hypervigilance, which involves being overly alert, easily startled, and constantly scanning their environment for potential threats. This heightened state of awareness is a common response to the trauma experienced. Choices A, C, and D are incorrect. Hyperactivity is not typically a primary manifestation of PTSD; restlessness may occur but is not as characteristic as hypervigilance, and although avoidance of social situations can be a symptom of PTSD, hypervigilance is more directly associated with the disorder.

Correct Answer: A

Rationale: In the case of a patient experiencing acute chest pain, the initial response should include administering prescribed nitroglycerin. Nitroglycerin helps dilate blood vessels and improve blood flow to the heart, which can be beneficial in managing chest pain related to cardiac issues. Providing oxygen can also be helpful to support oxygenation. However, the priority in this scenario is to address the potential cardiac cause by administering nitroglycerin. Calling for emergency assistance is crucial if the patient's condition does not improve or deteriorates. Reassuring the patient is essential for emotional support but should not be the primary intervention in the case of acute chest pain.

Correct Answer: A

Rationale: The correct answer is A: 'Monitor for changes in the level of consciousness.' Key signs of increased intracranial pressure (ICP) include changes in the level of consciousness and pupil dilation. Assessing for bradycardia and monitoring for vomiting are not typically considered primary signs of increased ICP. While bradycardia and vomiting can occur with increased ICP, they are not as specific or sensitive as changes in consciousness and pupil dilation.

Correct Answer: D

Rationale: In cases of anaphylaxis, all of the listed interventions are crucial for effective management. Administering epinephrine is the primary treatment to reverse the allergic reaction rapidly. Providing oxygen ensures adequate oxygenation to vital organs, and monitoring the airway is essential to prevent obstruction and maintain a clear air passage. Therefore, all three interventions are necessary in managing anaphylaxis. Choices A, B, and C are not individually sufficient to address all aspects of anaphylaxis, making the comprehensive approach of 'All of the above' the correct answer.

Correct Answer: D

Rationale: When managing a patient with diabetic ketoacidosis (DKA), it is crucial to administer insulin to lower blood sugar levels, administer IV fluids to correct dehydration and electrolyte imbalances, and monitor blood glucose levels regularly to ensure they are within the target range. Therefore, all of the above options are essential components of the comprehensive treatment plan for DKA. Administering insulin alone may lower blood sugar levels but will not address the fluid and electrolyte imbalances seen in DKA. Similarly, administering IV fluids alone may help with dehydration but will not address the high blood sugar levels or the need for insulin. Monitoring blood glucose alone is not sufficient to treat DKA; it must be accompanied by appropriate interventions to address the underlying causes and complications of the condition.
