A nurse is caring for a client who states, “I did not take my medication because my partner forgot to remind me.” The nurse should identify that the client is demonstrating which of the following defense mechanisms?
Rationalization
Projection
Repression
Regression
The Correct Answer is B
Choice A reason: Rationalization involves justifying behavior with logical excuses, not blaming others. The client attributes their failure to their partner, which is projection, making this incorrect for the defense mechanism.
Choice B reason: Projection involves attributing one’s own shortcomings, like forgetting medication, to another person, such as the partner. The client blames their partner, making this the correct defense mechanism.
Choice C reason: Repression is unconsciously blocking distressing thoughts, not blaming others. The client openly acknowledges the missed medication, so this is incorrect for the observed behavior.
Choice D reason: Regression involves reverting to childish behaviors, not blaming others. The client’s statement reflects externalizing responsibility, fitting projection, making this incorrect for the defense mechanism.

Correct Answer is D
Explanation
Choice A reason: Darkening the room may help but is less comprehensive than reducing all stimuli. Noise, light, and activity can exacerbate restlessness, so a broader approach is needed, making this incorrect.
Choice B reason: Applying restraints can increase agitation and injury risk in a restless client. Non-restrictive calming measures are preferred, making this incorrect for managing post-coma restlessness safely.
Choice C reason: Opioids may sedate but risk respiratory depression and mask neurological changes. Reducing stimuli is safer and addresses restlessness directly, making this incorrect for the care plan.
Choice D reason: Reducing stimuli, like noise and activity, calms the client emerging from a coma, preventing agitation. This aligns with TBI care to promote recovery, making it the correct intervention.
Correct Answer is A
Explanation
Choice A reason: Increasing ICP causes Cushing’s triad: bradycardia (P: 50), irregular respirations (R: 22), and widened pulse pressure (B/P: 140/60). These indicate brain compression, requiring immediate notification, making this the correct vital sign change.
Choice B reason: A pulse of 56 and B/P of 130/110 show hypertension but not widened pulse pressure. Respirations are mildly elevated, not irregular, making this less indicative of ICP than Cushing’s triad.
Choice C reason: P: 60, R: 18, and B/P: 126/96 are near normal, not reflecting Cushing’s triad. These changes are subtle and less concerning for acute ICP elevation, making this incorrect.
Choice D reason: P: 120 and B/P: 80/60 suggest shock, not ICP. Tachycardia and hypotension are opposite to Cushing’s triad, making this incorrect for indicating increasing intracranial pressure.
