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 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.
The nurse is assessing a client who is in the third trimester of pregnancy. Which finding would require immediate intervention by the nurse?
- A. Blood pressure of 142/92 mmHg
- B. Pulse of 92 beats per minute
- C. Respiratory rate of 24 per minute
- D. Weight gain of 16 oz per week
Correct Answer: A
Rationale: A blood pressure of 142/92 mmHg in a client in the third trimester of pregnancy is elevated and could indicate the development of preeclampsia, a serious hypertensive disorder that can have adverse effects on both the mother and the fetus. Preeclampsia is characterized by high blood pressure accompanied by signs of organ damage, such as proteinuria and changes in other laboratory values. Immediate intervention is required in this situation, as preeclampsia can lead to complications such as seizures (eclampsia), stroke, and placental abruption. It is essential for the nurse to further assess the client and notify the healthcare provider promptly for appropriate management.
A patient with a compound, open fracture of the femur is scheduled for immediate surgery. Which nursing diagnosis would be most appropriate in the immediate postoperative period?
- A. Risk for Falls
- B. Risk for Infection
- C. Impaired Transfer Ability
- D. Risk for Post-Trauma Syndrome
Correct Answer: B
Rationale: Given that the patient has a compound, open fracture of the femur and is undergoing immediate surgery, the most critical nursing diagnosis in the immediate postoperative period would be the risk for infection. Open fractures are particularly susceptible to infection due to the exposure of the fracture site to external contaminants. Postoperative care should prioritize infection prevention measures like sterile dressing changes, administration of prophylactic antibiotics, and close monitoring for signs of infection such as increased pain, redness, swelling, or drainage from the wound. Mitigating the risk of infection is crucial to prevent complications and promote optimal healing of the fracture. While the other diagnoses are relevant, addressing the risk for infection takes precedence in this scenario.
A client with sepsis has a temperature of 40°C. Which dysrhythmia is most likely to occur in this client?
- A. Bradydysrhythmia
- B. Tachydysrhythmia
- C. Wolff-Parkinson-White dysrhythmia
- D. Long QT dysrhythmia
Correct Answer: B
Rationale: A client with sepsis and a temperature of 40°C is likely experiencing a systemic inflammatory response, which can lead to a variety of dysrhythmias. In this case, the client is more likely to develop a tachydysrhythmia (fast heart rate) due to the body's response to the infection. Sepsis can result in an increase in heart rate as the body tries to maintain adequate perfusion to vital organs in response to the inflammatory process. Tachydysrhythmias such as supraventricular tachycardia or atrial fibrillation are commonly observed in septic patients with high fevers.
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.
