Answer to Question 1
D
This patient has been deprived of sleep by staying awake during a 28-hour labor. Disorientation is one potential sign of sleep deprivation. In this scenario, we have a clear cause for the patient's lack of sleep, and it is a one-time episode. Insomnia, on the other hand, is a chronic disorder whereby patients have difficulty falling asleep, awaken frequently, or sleep only for a short time. This scenario does not indicate that this has been a chronic problem for this patient. Although ineffective coping can manifest as a sleep disturbance, we have clear evidence that it was labor that deprived this patient of sleep, not an inability to cope. It could be difficult to care for an infant when sleep deprived; however, this scenario gives no evidence that this mother displays impaired parenting and is not caring adequately for her child or lacks the skills to do so.
