A nurse is caring for a client who develops a pulmonary embolism. Which of the following interventions is the priority for the nurse to take?

A. “You may feel some cramping during the procedure.” - This response provides an honest and accurate expectation of potential discomfort during the colonoscopy.

B. “Don’t worry, you won’t remember anything about the procedure due to the effects of the medication.” - Sedation may help with recall, but it doesn't eliminate the possibility of feeling discomfort.

C. “Most clients report more discomfort from the preparation than from the procedure itself.” - While this statement is generally true, it doesn't directly address the client's concern about pain during the colonoscopy.

D. “You shouldn’t feel any pain since the local area is anesthetized.” - Colonoscopy is typically done with conscious sedation rather than local anesthesia, and some discomfort may still be felt.

a. Begin oxygen therapy: Oxygen therapy is the priority intervention for a client with a pulmonary embolism to improve oxygenation and prevent hypoxemia.

b. Start an IV infusion of lactated Ringer’s: While fluid resuscitation may be needed, oxygen therapy takes precedence to address the immediate respiratory compromise.

c. Initiate cardiac monitoring: Cardiac monitoring is important, but addressing oxygenation is the priority in a client with a pulmonary embolism.

d. Administer IV morphine: Pain management may be necessary, but the priority is to address the respiratory distress and potential hypoxemia associated with a pulmonary embolism.
