During a Cardiac Stress test, a patient complains of chest pain while running The chest pain subsides when he stops running and is relaxed. The patient is diagnosed with Stable angina and is given education by the nurse. He understands the lack of muscles is causing stable angina during exercise.

Electrolytes

Oxygen

Potassium

Hemoglobin

Answer and Explanation

The Correct Answer is B

During exercise, the heart has to work harder to pump blood and oxygen to the muscles. In patients with stable angina, there is a partial blockage of the coronary arteries, which reduces blood ﬂow and oxygen delivery to the heart muscle. This lack of oxygen to the heart muscles causes chest pain or discomfort, which subsides when the patient stops exercising and is relaxed.

Therefore, it is important for the patient with stable angina to avoid activities that trigger chest pain, take prescribed medications, and make lifestyle modifications to manage their condition.

Correct Answer is A

Explanation

The left ventricle is responsible for pumping oxygen-rich blood from the heart to the rest of the body. In heart failure, the left ventricle is weakened and unable to pump blood efficiently, resulting in reduced blood ﬂow to the body's tissues. This can lead to symptoms such as fatigue, shortness of breath, and swelling in the legs and feet. Treatment for heart failure may include medications, lifestyle changes, and in some cases, surgical interventions such as a heart transplant.

A. Tonic B. Hypertonic C. Hypotonic D. Isotonic

Correct Answer is B

Explanation

Hypertonic solutions have a higher concentration of solutes (such as sodium, glucose, or mannitol) than the ﬂuid in the body's cells, causing water to move out of the cells and into the bloodstream. This results in the shrinking of the cells and an increase in extracellular ﬂuid volume.

Examples of hypertonic solutions include 10% dextrose in water (D10W), 3% saline, and 5% dextrose in 0.9% saline.

In contrast, isotonic solutions have the same concentration of solutes as the ﬂuid in the body's cells, and hypotonic solutions have a lower concentration of solutes than the ﬂuid in the body's cells.

Therefore, in this scenario, the nurse should administer a hypertonic solution to the client who requires IV ﬂuids.
