Final answer:
C) respiratory rate 11/min. The nurse should report the adverse effect of respiratory rate 11/min immediately to the provider. This may indicate respiratory depression, a serious adverse effect of morphine administration.
Step-by-step explanation:
The nurse should report the adverse effect of respiratory rate 11/min immediately to the provider. This respiratory rate is significantly lower than the normal range of 12-20 breaths per minute for an adult. It may indicate respiratory depression, a serious adverse effect of morphine administration that can lead to inadequate oxygenation and potential respiratory arrest.
Morphine is a potent opioid analgesic that can depress the central nervous system, including the respiratory centers in the brainstem. It can cause respiratory rate to decrease, leading to inadequate ventilation and oxygenation. This is a life-threatening situation that requires immediate intervention.
Emesis (vomiting) and sedation are known common adverse effects of morphine, but they are not as immediately concerning as respiratory depression. Blood pressure of 100/74 mmHg is within the normal range and does not require immediate reporting.
