The nurse is preparing a client for an echocardiogram. The client asks what the test can show Which of the following is a correct statement?

"The test will use a catheter to assess for blocked coronary arteries

The test can show how well your heart pumps blood."

The test will show proteins in the blood from damaged heart muscle.

The test shows the electrical activity of the heart from multiple angles”

Answer and Explanation

The Correct Answer is B

A) "The test will use a catheter to assess for blocked coronary arteries": This statement is incorrect. An echocardiogram does not involve the use of a catheter. It is a non-invasive imaging test that uses sound waves (ultrasound) to create images of the heart's structure and function. Assessing for blocked coronary arteries typically requires a different procedure, such as a coronary angiogram, which involves the use of a catheter.

B) "The test can show how well your heart pumps blood.": This is the correct statement. An echocardiogram is primarily used to assess how well the heart is functioning, including how effectively it pumps blood. It can provide detailed images of the heart's chambers, valves, and blood flow, helping to evaluate conditions such as heart failure, valve dysfunction, and other structural issues that may impair the heart’s ability to pump blood efficiently.
C) "The test will show proteins in the blood from damaged heart muscle.": This statement is incorrect. An echocardiogram does not measure blood proteins or markers from damaged heart muscle. Blood tests, such as troponin levels, are used to detect proteins released from heart muscle after injury, such as in a heart attack. The echocardiogram focuses on the heart's structure and function, not the chemical markers in the blood.

D) "The test shows the electrical activity of the heart from multiple angles.": This statement is inaccurate. The electrical activity of the heart is assessed by an electrocardiogram (ECG or EKG), not an echocardiogram. An ECG records the heart's electrical signals, while an echocardiogram uses sound waves to visualize the heart's anatomical structure and function.

Correct Answer is A

Explanation

A) "The patient has the virus but the infection is well controlled and not currently transmissible."
An undetectable viral load means that the amount of HIV in the blood is so low that it cannot be detected by standard laboratory tests, typically due to effective antiretroviral therapy. However, the patient still has the HIV virus in their body, and it is essential to continue treatment. An undetectable viral load reduces the risk of transmission, particularly to partners, but it does not eliminate the virus entirely. Hence, the infection is well controlled, but ongoing medication is still necessary to maintain viral suppression.

B) "The syndrome has gone from Stage 3 back to stage 2."
An undetectable viral load does not change the HIV stage. HIV is classified into three stages, with Stage 3 representing AIDS. While effective antiretroviral therapy can prevent the progression to AIDS and help control the viral load, it does not "reverse" the stage of HIV infection. Once a person progresses to Stage 3 (AIDS), they remain in this category even if their viral load becomes undetectable.

C) "The patient can discontinue with antiretroviral therapy until the viral load rises again."
An undetectable viral load indicates successful treatment, but it is crucial for the patient to continue taking antiretroviral medications to maintain viral suppression. Discontinuing therapy increases the risk of viral rebound and drug resistance. Long-term adherence to antiretroviral therapy is essential for keeping the virus under control.

D) "The patient will be prescribed lower doses of antiretroviral medications for 2 months.". The goal of antiretroviral therapy is to maintain viral suppression indefinitely, not to reduce the dose or discontinue it temporarily. Lowering the dose of antiretroviral medications could result in viral rebound and loss of viral suppression. Therefore, consistent, full-dose therapy is required for optimal HIV management.

A. The medication should be given with 5-6 hours of the onset of stroke systems B. The medication is a primary treatment for haemorrhagic stroke. C. The medication can be given to prevent clot formation in the context of head trauma D. When given within a certain timeframe, the medication may dissolve an ischemic stroke

Correct Answer is D

Explanation

A) "The medication should be given with 5-6 hours of the onset of stroke symptoms":
. tPA (tissue plasminogen activator) is typically given for an ischemic stroke, and it is most effective when administered within 3 to 4.5 hours of the onset of stroke symptoms. After this time frame, the risk of bleeding complications increases, and the benefits of the medication diminish significantly. Giving tPA after 6 hours is generally considered outside the therapeutic window for ischemic stroke, though some centers may extend the window based on specific criteria.

B) "The medication is a primary treatment for hemorrhagic stroke":
. tPA is contraindicated in hemorrhagic stroke because it works by dissolving clots, which could worsen bleeding in the brain. Hemorrhagic stroke occurs when there is bleeding in the brain, and administering tPA would exacerbate the bleeding, leading to more severe brain injury and complications. The primary treatment for hemorrhagic stroke is controlling bleeding, often through surgical interventions or managing blood pressure.

C) "The medication can be given to prevent clot formation in the context of head trauma":
. tPA is not used to prevent clot formation, particularly in the setting of head trauma. It is used to dissolve existing clots in cases of ischemic stroke. Administering tPA after head trauma or brain injury could lead to catastrophic complications, such as worsening bleeding, and should be avoided. The use of tPA is contraindicated in trauma-related situations unless the stroke is clearly ischemic and there are no signs of hemorrhage.

D) "When given within a certain timeframe, the medication may dissolve an ischemic stroke":
. tPA is the standard treatment for ischemic strokes (caused by a clot blocking blood flow to the brain). When administered within 3 to 4.5 hours of the onset of symptoms, tPA can dissolve the clot, improving blood flow to the affected area of the brain and potentially minimizing the damage caused by the stroke. Timely administration is critical for maximizing its benefits in reducing disability and improving outcomes.
