Concepts for Nursing Practice 3rd Edition Test Bank Questions

Question 1 of 5

The nurse is concerned that a client admitted for a total hip replacement is at risk for thrombus formation. Which assessment finding caused the nurse to draw this conclusion?

Correct Answer: B

Rationale: A former cigarette smoker is at increased risk for thrombus formation due to the damage smoking causes to the blood vessels, increasing the likelihood of blood clots. Smoking can also contribute to inflammation and increased platelet activation, further promoting clot formation. This risk factor is particularly concerning in a client undergoing a total hip replacement surgery, as immobility and surgery itself can also increase the risk of blood clots forming. Monitoring and addressing this risk factor is important in preventing potential complications such as deep vein thrombosis or pulmonary embolism in this client population. While the other assessment findings are important to consider for overall health, the former cigarette smoking status is specifically associated with thrombus formation in this scenario.

Question 2 of 5

The nurse is providing care to a client who has experienced several episodes of angina. Which agent does the nurse anticipate being ordered to reduce the intensity and frequency of an angina episode?

Correct Answer: C

Rationale: Nitrates are commonly prescribed for the management of angina. These agents work by dilating blood vessels, which leads to improved blood flow to the heart muscle and decreased workload on the heart. This results in reduced intensity and frequency of angina episodes by increasing oxygen supply to the heart and decreasing its demand. Nitrates can be administered sublingually, orally, or topically to provide prompt relief of chest pain during an angina episode. Thorough patient education should be provided regarding the proper use of nitrates and potential side effects.

Question 3 of 5

What is the most accurate tool for assessing and diagnosing venous thrombosis?

Correct Answer: B

Rationale: Duplex venous ultrasonography is the most accurate tool for assessing and diagnosing venous thrombosis. It is a non-invasive imaging technique that combines Doppler flow studies with conventional ultrasonography. This allows for the visualization of blood flow in the veins and identification of any blood clots or obstructions. Duplex venous ultrasonography is highly sensitive and specific for detecting deep vein thrombosis (DVT) in the lower extremities, making it the preferred imaging modality for diagnosing venous thrombosis. Other imaging modalities like ascending contrast venography, magnetic resonance imaging, and plethysmography are less commonly used due to their disadvantages compared to duplex venous ultrasonography such as invasiveness, cost, and lower accuracy.

Question 4 of 5

The nurse is caring for a client admitted to the hospital with lower extremity edema and shortness of breath. Which electrocardiogram finding indicates the client is at risk for an alteration in perfusion?

Correct Answer: D

Rationale: An isoelectric ST segment on an electrocardiogram can indicate myocardial ischemia or injury, which can lead to a decrease in perfusion to the heart muscle. This finding suggests an increased risk of inadequate blood flow to the heart, potentially resulting in further complications such as a myocardial infarction or altered perfusion to other organs. In a client with lower extremity edema and shortness of breath, identifying this ECG finding is crucial for early intervention and monitoring to prevent further deterioration in perfusion status.
