A patient presents with a heart rate of 130 beats/minute and a blood pressure of 82/66 after exerting themselves in the sun. Which of the following interventions would be most appropriate?

Administer a hypotonic solution

Administer a vasoconstrictor medication

Administer an isotonic solution intravenously

Administer a hypertonic solution intravenously

Answer and Explanation

The Correct Answer is C

A. Administering a hypotonic solution would not be appropriate in this case. Hypotonic solutions can lower the blood pressure further and worsen the patient’s condition.
B. Administering a vasoconstrictor medication may increase blood pressure, but it is not the first-line treatment for dehydration or volume loss, which seems to be the cause of the patient’s symptoms.
C. Administering an isotonic solution intravenously is the most appropriate intervention. The patient is likely experiencing dehydration and hypotension due to fluid loss from exertion in the sun (possibly heat exhaustion). Isotonic fluids such as normal saline or lactated Ringer's solution are typically used to restore circulating volume and improve blood pressure.
D. Administering a hypertonic solution would be inappropriate, as it could increase the osmolarity of the blood and worsen dehydration, potentially causing fluid shifts that could lead to complications such as cellular dehydration.

A. The pain comes from severed blood vessels in the residual stump. B. It is psychosomatic pain that the patient is just imagining. C. It is often treated with adjunct medications such as antiepileptics and antidepressants. D. It is somatic pain that always responds well to opioid medications.

Correct Answer is C

Explanation

A. The pain does not come from severed blood vessels in the residual stump. Phantom limb pain is not caused by the stump itself but rather by the brain’s perception of the missing limb.
B. Phantom limb pain is not psychosomatic. It is a real phenomenon where the brain continues to receive signals from nerves that were previously connected to the amputated limb.
C. Phantom limb pain is often treated with adjunct medications such as antiepileptics (e.g., gabapentin) and antidepressants (e.g., amitriptyline), which help modify the way the brain processes pain signals.
D. While opioid medications can be used for pain management, phantom limb pain often does not respond well to opioids. It typically requires a combination of other treatments, such as those mentioned in C.
