What are the risk factors for deep vein thrombosis (DVT) and how can it be prevented?

Correct Answer: A

Rationale: The correct answer is A: Immobility and oral contraceptive use. Immobility and oral contraceptive use are significant risk factors for deep vein thrombosis (DVT). Immobility leads to blood stasis, increasing the risk of clot formation, while oral contraceptive use can promote hypercoagulability. Prevention strategies for DVT include promoting mobility to enhance blood circulation and using anticoagulants to prevent clot formation. Choices B, C, and D are incorrect. While pregnancy and smoking can increase the risk of DVT, they are not the specific factors mentioned in the question. Similarly, obesity and varicose veins, as well as hypertension and high cholesterol, are not the primary risk factors associated with DVT.

Correct Answer: A

Rationale: Corrected Rationale: Untreated fluid overload can lead to complications such as pulmonary edema and congestive heart failure. Pulmonary edema occurs when excess fluid accumulates in the lungs, leading to difficulty breathing and potentially life-threatening respiratory distress. Congestive heart failure can result from the heart's inability to pump effectively due to the excess fluid volume, leading to symptoms such as fatigue, shortness of breath, and fluid retention. Choices B, C, and D are incorrect because hypertension, liver failure, pulmonary embolism, and dehydration are not the primary complications directly associated with untreated fluid overload.

Correct Answer: A

Rationale: When assessing a patient with chest pain, the initial step is to assess the severity of pain and monitor the electrocardiogram (ECG) to look for signs of cardiac issues. Administering nitroglycerin and oxygen (Choice B) is a treatment option for suspected cardiac chest pain but should not precede a thorough assessment. Administering aspirin and providing pain relief (Choice C) may be indicated later, but the priority is to assess the situation first. Monitoring for nausea and administering IV fluids (Choice D) is not the initial assessment for chest pain unless there are specific indications present.

Correct Answer: A

Rationale: Corrected Question: When managing a patient with fluid overload, the appropriate approach involves restricting fluids and administering diuretics. This strategy helps remove excess fluid from the body and prevent complications associated with fluid overload. Choice B suggesting increasing fluid intake is incorrect as it would worsen the condition. Choice C, administering antibiotics, is unrelated to managing fluid overload. Choice D, monitoring weight and providing a low-sodium diet, is helpful but not as effective as fluid restriction and diuretics in managing fluid overload.

Correct Answer: A

Rationale: Monitoring urine output and ensuring proper catheter drainage are crucial aspects of managing a patient with an indwelling urinary catheter. This helps in assessing the patient's renal function, fluid balance, and the patency of the catheter. Administering antibiotics and changing the catheter regularly (Choice B) may not be necessary unless there is an infection present. While monitoring for signs of infection and providing catheter care (Choice C) are important, the primary focus should be on urine output and drainage. Providing a high-sodium diet and monitoring hydration (Choice D) are not directly related to managing an indwelling urinary catheter.
