George, an 85yearold man with a history of chronic obstructive pulmonary disease, was rushed to the emergency department with increasing shortness of breath, restlessness, and difficulty communicating due to his inability to complete a sentence. On assessment, tachycardia and a bounding pulse were noted. Wheezes could be heard in the lower lobes. His blood gas shows a pH of 7.3, PaCO2 of 68 mmHg, HCO3 of 28 mmol/L, and PaO2 of 60 mmHg. How would you interpret this?
Metabolic Acidosis, Uncompensated
Metabolic Acidosis, Partially Compensated
Respiratory Acidosis, Partially Compensated
Respiratory Acidosis, Uncompensated
The Correct Answer is C
Choice A reason: Metabolic acidosis is characterized by a low pH and a low HCO3. However, George's HCO3 is within normal range, indicating that metabolic acidosis is not the primary issue.
Choice B reason: Partially compensated metabolic acidosis would present with a low pH and a low HCO3, along with a low PaCO2 as the body attempts to compensate. George's PaCO2 is elevated, which is not consistent with this condition.
Choice C reason: George's high PaCO2 and near normal HCO3 suggest that his primary issue is respiratory acidosis. The body has begun to compensate by retaining HCO3, making it partially compensated.
Choice D reason: Uncompensated respiratory acidosis would present with an elevated PaCO2 and a normal HCO3. Since George's HCO3 is elevated, it indicates partial compensation.

Explanation
Choice A reason: Avoiding driving in winter is not necessary unless it is a personal trigger for Raynaud's attacks. It's more important to keep warm and manage stress.
Choice B reason: Stress management classes can teach techniques to control stress, which is beneficial for clients with Raynaud's disease as stress can trigger episodes.
Choice C reason: Using nicotine gum to quit smoking is a positive step for overall health, but it is not directly related to the management of Raynaud's disease.
Choice D reason: Limiting coffee intake may help some individuals with Raynaud's disease, as caffeine can constrict blood vessels, but it is not a universal recommendation.
Correct Answer is B
Explanation
Choice A reason: Tennis involves abrupt lateral movements and may not be suitable for someone with low back pain, as it can exacerbate the condition.
Choice B reason: Swimming is a low impact exercise that can help strengthen the back muscles without putting additional stress on the spine, making it an ideal choice for individuals with low back pain.
Choice C reason: The option "Custom: NUR 224G Sec 2 Blandon Final" does not refer to a specific exercise and seems to be an error or unrelated text.
Choice D reason: Rowing can be strenuous on the lower back due to the repetitive motion and the need for strong core engagement, which might not be recommended for acute low back pain.
