The nurse is caring for a client who is undergoing an exercise stress test. Prior to reaching the target heart rate, the client develops chest pain. What is the nurse’s most appropriate interpretation of the chest pain?

The patient pain reflects the target heart rate has been set too high and needs to be lowered to finish the test.

The patient’s pain reflects pericarditis and the test should be stopped.

The patient’s pain reflects ischemia to the myocardium and the test should be stopped.

The patient’s pain reflects that supplemental oxygen is needed to finish the test.

Answer and Explanation

The Correct Answer is C

A. The patient pain reflects the target heart rate has been set too high and needs to be lowered to finish the test.

This option suggests that the chest pain is related to the target heart rate being set too high. However, chest pain during an exercise stress test is more commonly associated with myocardial ischemia rather than an inappropriate target heart rate. Lowering the target heart rate may not address the underlying issue of ischemia.

B. The patient’s pain reflects pericarditis and the test should be stopped.

Chest pain during an exercise stress test is more commonly associated with myocardial ischemia rather than pericarditis. Pericarditis is inflammation of the pericardium, and its symptoms may include chest pain that is often sharp and pleuritic. However, during an exercise stress test, the focus is on detecting cardiovascular abnormalities, and chest pain is more concerning for ischemia.

C. The patient’s pain reflects ischemia to the myocardium and the test should be stopped.

This is the most appropriate interpretation. Chest pain during an exercise stress test may indicate insufficient oxygen supply to the myocardium (ischemia). Stopping the test allows for further evaluation and appropriate intervention.

D. The patient’s pain reflects that supplemental oxygen is needed to finish the test.

Chest pain during an exercise stress test is not typically addressed by providing supplemental oxygen. Stopping the test and evaluating the cause of the chest pain is a more appropriate action.

Correct Answer is A

Explanation

A. Mask:

Silicosis is a lung disease caused by inhaling crystalline silica dust. The primary preventive measure during exposure to silica particles is wearing a mask or respirator. This helps to reduce the inhalation of silica dust, protecting the respiratory system.

B. Gloves: Gloves are typically worn to protect the hands and skin and are not directly related to preventing inhalation of airborne particles.

C. Eye Protection: While eye protection is important in certain occupational settings, it does not specifically address the inhalation of silica particles.

D. Gown: Gowns are worn for protection against contamination but are not directly related to the prevention of occupational lung diseases such as silicosis.

Correct Answer is ["4"]

Explanation

Warfarin (Coumadin) is an anticoagulant medication that prevents blood clots from forming or growing larger. It is prescribed for clients who have atrial fibrillation, deep vein thrombosis, pulmonary embolism, or artificial heart valves.

The physician orders warfarin 10 mg PO to be administered to a client at 1800 today. The pharmacy only has 2.5 mg tablets available. To calculate the number of tablets that the nurse will administer, the nurse will divide the ordered dose by the available dose. The formula is:

Number of tablets = Ordered dose / Available dose

Number of tablets = 10 mg / 2.5 mg

Number of tablets = 4

Therefore, the nurse will administer 4 tablets of warfarin 2.5 mg PO to the client at 1800 today
