A nurse suspects a client who has myasthenia gravis is experiencing a myasthenic crisis. Which of the following interventions should the nurse take?

An exercise stress test is a diagnostic procedure that measures the heart's response to physical activity. The client is instructed to walk on a treadmill or pedal a stationary bike while their heart rate, blood pressure, and electrocardiogram are monitored. The test can help detect coronary artery disease, arrhythmias, or other cardiac problems.

The client should follow certain guidelines before the test, such as:

• Avoiding caffeine, nicotine, alcohol, and stimulants for at least 4 hours before the test, as they can affect the heart rate and blood pressure.
• Fasting for at least 2 hours before the test, as eating can affect the blood flow to the heart.
• Getting adequate rest and sleep the night before the test, as fatigue can affect the performance and results of the test.
• Wearing comfortable clothing and shoes that are suitable for exercise.
• Informing the provider of any medications they are taking, as some medications may need to be withheld or adjusted before the test, such as beta blockers, calcium channel blockers, nitrates, or antiarrhythmics. These medications can affect the heart rate and blood pressure and interfere with the interpretation of the test results.

Therefore, the comment made by the client that indicates a need for further teaching is "I'll take my heart medications the morning of my test." The client should consult with their provider about whether they should take their heart medications or not before the test. The other comments made by the client are appropriate and indicate that they understand the pre-test instructions.

The nurse should identify that this client has multiple risk factors for cardiovascular disease, such as hypertension, obesity, and smoking. These factors can increase the risk of atherosclerosis, coronary artery disease, stroke, and peripheral vascular disease.

Depression is wrong because it is not directly related to the client's physical examination findings. Depression may have other risk factors, such as genetics, stress, trauma, or substance abuse.

Thyroid disease is wrong because it is not directly related to the client's physical examination findings. Thyroid disease may have other risk factors, such as autoimmune disorders, iodine deficiency, or radiation exposure.

Testicular cancer is wrong because it is not directly related to the client's physical examination findings. Testicular cancer may have other risk factors, such as cryptorchidism, family
