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
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.

Correct Answer is C
Explanation
A. This describes a transverse fracture, where the bone breaks completely across and perpendicular to the shaft. It does not describe a greenstick fracture.
B. A spiral fracture is caused by a twisting force, which results in a helical break. This is not a greenstick fracture.
C. A greenstick fracture occurs when the bone bends and cracks on the outer arc but does not break completely through. This type of fracture is more common in children because their bones are softer and more flexible.
D. This describes a comminuted fracture, where the bone breaks into several pieces. It does not match the description of a greenstick fracture.
Correct Answer is B
Explanation
A. Assessing blood pressure with a sphygmomanometer is unrelated to Chvostek's sign, which specifically evaluates neuromuscular excitability.
B. Chvostek's sign is assessed by tapping the facial nerve near the cheekbone. A positive response, such as twitching of the facial muscles, indicates hypocalcemia or neuromuscular irritability.
C. Assessing heart rate with a stethoscope does not involve evaluating neuromuscular function or calcium levels.
D. Monitoring respiratory rate with a pulse oximeter is unrelated to Chvostek's sign and does not assess neuromuscular excitability.
