The nurse is screening a client prior to an magnetic resonance imaging (MRI). What information is important to report to the health care provider before the MRI?

The client has a permanent cardiac pacemaker

The client has a history of atherosclerosis.

The client took the prescribed heart medications today

The client has an allergy to shellfish.

Answer and Explanation

The Correct Answer is A

Having a permanent cardiac pacemaker is a significant factor that needs to be communicated to the health care provider before undergoing an MRI. Magnetic resonance imaging (MRI) uses powerful magnets, radio waves, and a computer to create detailed images of the body. The presence of a cardiac pacemaker can be a contraindication for undergoing an MRI because the strong magnetic field can potentially interfere with the functioning of the pacemaker or cause it to malfunction. It is crucial to assess the compatibility of the pacemaker with the MRI machine and to take appropriate precautions or make necessary arrangements to ensure the safety of the client during the procedure.

While the other pieces of information provided may be relevant to the client's overall health and medical history, they may not have a direct impact on the safety or feasibility of undergoing an MRI.

Correct Answer is ["A","B","C","D"]

Explanation

Assess pulse of the affected extremity every 15 minutes at ﬁrst: Frequent assessment of the pulse in the affected extremity is important to monitor for any changes in blood ﬂow. This allows the nurse to identify any potential complications such as graft occlusion or compromised circulation promptly.

Palpate the affected leg for pain during every assessment: Assessing for pain in the affected leg is crucial to identify any signs of ischemia or inadequate perfusion. Increased pain could indicate reduced blood ﬂow or other complications that require immediate attention.

Assess the client for signs and symptoms of compartment syndrome every 2 hours: Compartment syndrome can occur after vascular surgeries, and early recognition is vital. The nurse should assess for signs and symptoms such as pain, numbness, tingling, increased swelling, and tense compartments. Regular assessment every 2 hours can help detect compartment syndrome promptly and prevent further complications.

Perform Doppler evaluation once daily: Doppler evaluation may be ordered by the healthcare provider to assess blood ﬂow and graft patency. However, the frequency of Doppler evaluation may vary depending on the client's condition and the healthcare provider's orders. Once daily assessment is not suﬃcient if there are concerns regarding blood ﬂow or graft viability.

A. "Increased LDL and decreased HDL increase my risk of coronary artery disease." B. "Increased LDL has the potential to decrease my risk of heart disease." C. "The decreased HDL level will increase the amount of cholesterol moved away from the artery walls." D. "The increased LDL will decrease the amount of cholesterol deposited on the artery walls."

Correct Answer is A

Explanation

Elevated levels of LDL (low-density lipoprotein) cholesterol are associated with an increased risk of coronary artery disease (CAD). LDL cholesterol is often referred to as "bad" cholesterol because it can contribute to the formation of plaque in the arteries, leading to narrowing and blockage of the arteries supplying the heart. This increases the risk of developing CAD and related complications such as heart attack and stroke.

On the other hand, HDL (high-density lipoprotein) cholesterol is often referred to as "good" cholesterol. HDL cholesterol helps remove excess cholesterol from the bloodstream and transport it back to the liver for processing and excretion. Higher levels of HDL cholesterol are associated with a decreased risk of CAD because it helps to prevent the accumulation of cholesterol on artery walls.

Therefore, understanding that increased LDL and decreased HDL levels increase the risk of coronary artery disease demonstrates a good understanding of the significance of cholesterol levels and their impact on cardiovascular health.
