Final answer:
The patient with a blood pH of 7.6 is more likely to experience aggravated tetany due to alkalosis, which reduces the ionized calcium in the blood, increasing neuromuscular excitability.
Step-by-step explanation:
- In considering two different patients with arterial blood pH of 7.6 and 7.4, respectively, the patient with the blood pH of 7.6 is more likely to experience aggravated tetany.
- Tetany can be worsened by an increased blood pH, which reduces the ionized fraction of serum calcium.
- This reduction in ionized calcium (hypocalcemia) increases neuromuscular excitability, leading to symptoms such as muscle spasms or cramping.
- The blood pH level of 7.6 indicates a condition of alkalosis, which can lead to symptoms like muscle twitching and spasm.
- On the other hand, a blood pH of 7.4 is within the normal range (7.35 to 7.45) and less likely to contribute to the aggravation of tetany.
