What is the most accurate tool for assessing and diagnosing venous thrombosis?
- A. Ascending contrast venography
- B. Duplex venous ultrasonography
- C. Magnetic resonance imaging
- D. Plethysmography
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.

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?
- A. Body mass index (BMI) 35.8
- B. Former cigarette smoker
- C. Blood pressure 132/88 mmHg
- D. Age 45 years
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.
After being diagnosed with polycystic kidney disease, an adult patient asks if current children are at risk for developing the disorder. How should the nurse respond?
- A. The adult form of this disorder is rare and should not affect grown children
- B. The children should undergo genetic testing and screening for evidence of the disease
- C. Because the condition was just diagnosed, there is no risk of passing the condition on to any children
- D. The children would have developed symptoms of the disorder in utero or shortly after birth if they had inherited the defective gene
Correct Answer: B
Rationale: Polycystic kidney disease (PKD) is a genetic disorder that can be inherited by children if one or both parents have the gene mutation responsible for the condition. In cases where a parent has been diagnosed with PKD, their children are at risk of inheriting the faulty gene. As such, it is recommended for the children to undergo genetic testing and screening to identify any evidence of the disease early on. By identifying the gene mutation in the children, appropriate monitoring and management can be initiated, potentially leading to better outcomes and quality of life for the affected individuals. Therefore, genetic testing and screening are crucial in cases where there is a known genetic component to a disorder like PKD.
A 14-year-old child was recently diagnosed with hypertrophic cardiomyopathy. During a follow-up appointment, the mother asks the nurse, "How will this affect my child's ability to play football in the fall?" How should the nurse respond?
- A. "This shouldn't affect his ability to play football."
- B. "Children with cardiomyopathy should not play football."
- C. "He could participate in flag football but not tackle football."
- D. "This may actually make him a better, stronger football player."
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.
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?
- A. The client will experience relief of chest pain with therapeutic lifestyle changes.
- B. The client will experience relief of chest pain with statin therapy.
- C. The client will experience relief of chest pain with nitrate therapy.
- D. The client will experience relief of chest pain with anticoagulant therapy.
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.
The nurse has a 7-year-old client recovering from partial-thickness burns to the arms and hands. This client has shown sensitivity to loud noises and bright lights, and at times if she is overstimulated she won't speak to or look at anyone but her parents until she calms down. The nurse considers the best teaching environment for this client to be the
- A. client's room.
- B. pediatric ward waiting area.
- C. hospital cafeteria.
- D. pediatric ward play area.
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.
