Final answer:
In hypovolemic shock, vital signs should be measured every 15 minutes to closely monitor the patient's condition and the effectiveness of treatment.
Step-by-step explanation:
Frequency of Vital Sign Measurement in Hypovolemic Shock
In the case of hypovolemic shock, vital signs should be observed more frequently due to the potential for rapid changes in the patient's condition. The correct frequency for measuring vital signs in this scenario is every 15 minutes (option c). During hypovolemic shock, patients may exhibit a range of symptoms including a rapid heart rate, weak pulse, cool and clammy skin, rapid and shallow breathing, hypothermia, and thirst. Immediate and repeated monitoring of vital signs is crucial for assessing the severity of the shock and the effectiveness of the treatment, which often involves the administration of intravenous fluids and vasoactive drugs like dopamine, epinephrine, and norepinephrine.
