Final answer:
In a situation where a patient has no respiration and decreased vital signs, immediate action is necessary. Checking for a pulse and beginning CPR should be done without delay. Waiting for emergency medical assistance is also critical.
Step-by-step explanation:
If you notice that Mrs. Small's vital signs are decreased and her respiration is zero, this is an immediate medical emergency. The lack of respiration (apnea) suggests that she is not breathing, and the decreased vital signs may indicate a failure of the cardiovascular system. In this situation, it is critical to check for a pulse and breathing, and if absent, begin cardiopulmonary resuscitation (CPR) immediately and call for emergency services. The absence of normal electrical heart activity normally leads to an absence of heart rate (pulse). In newborns, this scenario would be reflected in the Apgar score, with a significant need for resuscitation when a score is extremely low. Prompt action is essential in such cases to restore oxygen to the brain and vital organs.
