The nurse is caring for a patient with hyperkalemia. Which body system assessment is the priority?
Cardiac
Neurological
Gastrointestinal
Respiratory
The Correct Answer is A
A. Hyperkalemia can lead to dangerous cardiac arrhythmias and other heart-related complications due to its effect on the electrical conduction system of the heart, making cardiac assessment the priority.
B. While neurological assessment is important in various conditions, it is secondary to assessing cardiac status in hyperkalemia.
C. Gastrointestinal symptoms can occur with hyperkalemia, but they do not pose an immediate life-threatening risk like cardiac issues do.
D. Respiratory assessment is essential in many contexts, but the immediate threat of hyperkalemia lies in its impact on heart function, making cardiac assessment the most critical.

Correct Answer is D
Explanation
A. The superior vena cava is responsible for returning deoxygenated blood from the upper body to the heart and is not directly involved in myocardial ischemia.
B. The carotid artery supplies blood to the brain and is not the primary focus in the context of myocardial infarction.
C. The pulmonary artery carries deoxygenated blood from the heart to the lungs and is not involved in coronary circulation.
D. The coronary arteries supply blood to the heart muscle itself. Ischemia during a myocardial infarction occurs when these arteries are blocked or narrowed, leading to a lack of blood flow and oxygen to the heart tissue.
Correct Answer is ["A","B","C","D","F"]
Explanation
A. Applying knowledge of disease processes is essential in preventing the spread of infections and understanding transmission routes.
B. Proper disposal of supplies is crucial in minimizing the risk of cross-contamination and infection spread.
C. Checking the negative-pressure system is critical to ensure it functions properly to contain airborne pathogens.
D. Hand hygiene is a key practice in preventing infection and should be performed before and after patient contact in both scenarios.
E. This statement is misleading; while some precautions may overlap, there are specific differences that must be addressed in interventions for airborne versus contact precautions.
F. It is important for patients in airborne precautions to wear a mask during transportation to prevent the spread of infectious particles.
