A client is admitted to the Emergency Department with a suspected STEMI. The nurse anticipates that this client will be immediately prepared for the cardiac catheterization laboratory because the goal of treatment is to:

measure heart chamber pressures to assess for heart failure.

evaluate the extent of occlusion of the coronary arteries involved.

determine cardiac output during the procedure.

prevent extensive myocardial damage.

Answer and Explanation

The Correct Answer is D

A. Measure heart chamber pressures to assess for heart failure: While measuring heart chamber pressures may be important in other situations, it is not the immediate goal in the treatment of a suspected STEMI (ST-Elevation Myocardial Infarction). The priority in STEMI is to restore blood flow to the affected area of the heart, not to assess for heart failure through pressure measurements.

B. Evaluate the extent of occlusion of the coronary arteries involved: Although evaluating the extent of coronary artery occlusion is a part of the procedure, it is not the immediate goal. The priority in STEMI treatment is rapid reperfusion of the blocked artery to minimize myocardial damage. The catheterization will help guide interventions like angioplasty or stent placement to restore blood flow.

C. Determine cardiac output during the procedure: While cardiac output may be monitored during the procedure, the primary goal of the catheterization in a suspected STEMI is not to determine cardiac output but to restore blood flow to the heart and minimize the damage to the heart muscle.

D. Prevent extensive myocardial damage: The primary goal of immediate treatment for STEMI is to restore blood flow to the blocked coronary artery as quickly as possible, either through primary PCI (Percutaneous Coronary Intervention), angioplasty, or thrombolytics, in order to prevent extensive damage to the heart muscle. The earlier blood flow is restored, the less damage occurs to the heart tissue, which is critical for improving outcomes.

Correct Answer is C

Explanation

A. GI & cerebral blood flow: the body’s overall blood flow is important, myocardial oxygen consumption is more directly related to the heart's workload. GI and cerebral blood flow do not have a direct impact on myocardial oxygen demand.

B. Renal blood flow: Renal blood flow does not directly affect myocardial oxygen consumption. The heart's oxygen needs are more influenced by factors such as heart rate, contractility, preload, and afterload rather than the blood flow to the kidneys.

C. Heart rate & contractility: Myocardial oxygen consumption increases as the heart rate and contractility increase. Both heart rate (the number of beats per minute) and contractility (the strength of each contraction) require more oxygen to function. As these factors increase, the heart has to work harder, thus consuming more oxygen.

D. Cerebral blood flow: While cerebral blood flow is essential for brain function, it does not directly influence myocardial oxygen consumption. The heart’s oxygen needs are more closely linked to factors that affect the heart's workload, such as preload, afterload, heart rate, and contractility.

A. ondansetron (Zofran) and metoclopramide (Reglan). B. haloperidol (Haldol) and chlorpromazine (Thorazine). C. risperidone (Risperdal) and quetiapine (Seroquel). D. Riluzole (Rilutek) and baclofen (Lioresal).

Correct Answer is C

Explanation

A. Ondansetron (Zofran) and metoclopramide (Reglan): These medications are used to treat nausea and vomiting, often related to gastrointestinal issues or as side effects of other treatments. They are not indicated for the treatment of Huntington's Disease (HD), which primarily involves movement and psychiatric symptoms.

B. Haloperidol (Haldol) and chlorpromazine (Thorazine): These are antipsychotic medications that can be used to treat the psychiatric symptoms of Huntington's Disease (such as agitation, psychosis, and chorea). However, they are older, first-generation antipsychotics and are associated with more severe side effects, such as extrapyramidal symptoms. While they can still be used, they are generally less favored due to these side effects.

C. Risperidone (Risperdal) and quetiapine (Seroquel): These are atypical antipsychotic medications, which are often preferred for managing psychiatric symptoms (e.g., psychosis, aggression, mood disturbances) in Huntington's Disease. These medications have a lower risk of extrapyramidal symptoms compared to first-generation antipsychotics, making them a better choice for patients in the later stages of HD.

D. Riluzole (Rilutek) and baclofen (Lioresal): Riluzole is used in amyotrophic lateral sclerosis (ALS), not Huntington's Disease. Baclofen is a muscle relaxant that can be used to manage spasticity, but it is not a primary treatment for HD. The focus for HD treatment would be more on managing movement disorders and psychiatric symptoms, rather than spasticity.
