Concepts for Nursing Practice 3rd Edition Test Bank

Correct Answer: A

Rationale: For a 7-year-old client recovering from partial-thickness burns with sensitivity to loud noises and bright lights, along with a tendency to become overstimulated, the best teaching environment would be the client's room. This setting provides a familiar and comforting space where the client feels secure and less exposed to external stimuli that may trigger discomfort or anxiety. Being in her own room allows the client to focus better, feel more at ease, and have better communication with the nurse without distractions from bright lights, loud noises, or other people around. This controlled and peaceful environment contributes to a more effective teaching and learning experience for the client, promoting better understanding and retention of information.

Correct Answer: B

Rationale: Children diagnosed with hypertrophic cardiomyopathy should not participate in competitive sports such as football due to the potential risk of sudden cardiac events. Physical activity and sports with lower intensity may be allowed, but organized competitive sports with high intensity (such as football) are generally contraindicated. It is important for the health care team to prioritize the child's safety and well-being over sports participation in cases of cardiomyopathy. The nurse should communicate this information to the mother to help her understand the importance of limiting the child's physical activities to reduce the risk of complications related to hypertrophic cardiomyopathy.

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.

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.

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.
