A nurse is providing care for a client experiencing obstructive shock. Which of the following diagnoses should the nurse expect?
Cardiac tamponade
Third spacing
Ruptured aneurysm
Cardiomyopathy
The Correct Answer is A
A. Cardiac tamponade is a condition where fluid accumulates in the pericardial space, exerting pressure on the heart and impeding its ability to pump effectively, leading to obstructive shock.
B. Third spacing refers to fluid accumulation in the interstitial spaces but is not a specific diagnosis of obstructive shock.
C. A ruptured aneurysm may lead to hypovolemic shock due to blood loss rather than obstructive shock, which is characterized by physical obstruction to blood flow.
D. Cardiomyopathy is a disease of the heart muscle that affects its ability to pump blood, leading to cardiogenic shock, not obstructive shock.

Correct Answer is D
Explanation
A. Increasing the infusion rate may exacerbate the patient's symptoms and does not address the potential toxicity from the furosemide.
B. Normal potassium levels indicate that potassium supplementation is unnecessary and does not address the dizziness and ringing in the ears, which could suggest ototoxicity from furosemide.
C. While reassurance can help, the patient's symptoms indicate a potential adverse reaction to the medication that should not be ignored.
D. Stopping the furosemide infusion and notifying the provider is the most appropriate action due to the risk of ototoxicity and the need for further evaluation of the patient's symptoms.
