Examples of patients suffering from impaired awareness include all of the following except:
- A. A semiconscious or overfatigued patient
- B. A disoriented or confused patient
- C. A patient who cannot care for themselves at home
- D. A patient demonstrating symptoms of drug or alcohol withdrawal
Correct Answer: C
Rationale: Patients with impaired awareness may exhibit symptoms such as being semiconscious, overfatigued, disoriented, confused, or demonstrating symptoms of drug or alcohol withdrawal. A patient who cannot care for themselves at home does not necessarily indicate impaired awareness, as this could be due to physical limitations or lack of support, rather than a cognitive deficit.

If a patient's blood pressure is 150/96, what is his pulse pressure?
- A. 54
- B. 96
- C. 150
- D. 246
Correct Answer: A
Rationale: Pulse pressure is calculated by subtracting the diastolic pressure from the systolic pressure. In this case, the systolic pressure is 150 and the diastolic pressure is 96. Therefore, the pulse pressure is 150 - 96 = 54. Pulse pressure represents the force generated by the heart with each contraction and is an important indicator of cardiovascular health.
