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: B

Rationale: The correct answer is B because pallor in an extremity after a fracture could indicate compromised circulation, making it a priority for assessment. Choice A is not the priority as hypoactive bowel sounds in a client 1 hr postoperative, while concerning, do not indicate a life-threatening condition. Choice C, a client who had a cardiac catheterization 3 hr ago and has 3+ pedal pulses, indicates good perfusion and does not require immediate attention. Choice D, a client with an elevated AST level following the administration of azithromycin, may require further assessment but is not as urgent as the client with potential compromised circulation in choice B.

Correct Answer: B

Rationale: Irritability is an early sign that suctioning is required to clear secretions in a client with a tracheostomy. Hypotension, flushing, and bradycardia are not direct indicators for suctioning a tracheostomy. Hypotension may indicate a need for fluid resuscitation or other interventions, flushing could be due to various reasons like fever, and bradycardia may require evaluation for cardiac causes.

Correct Answer: B

Rationale: The correct answer is B: 'As soon as the client awakens in the morning.' Sputum specimens should be collected early in the morning to obtain a concentrated sample. This timing ensures that the specimen is less diluted, providing a more accurate analysis. Choices A, C, and D are incorrect as they do not align with the optimal timing for collecting a sputum specimen, which is in the morning.

Correct Answer: A

Rationale: Diabetic ketoacidosis and retinopathy are indeed common complications of untreated Type 1 diabetes. Diabetic ketoacidosis occurs when the body starts breaking down fat for fuel, leading to a dangerous buildup of ketones in the blood. Retinopathy refers to damage to the blood vessels of the retina due to high blood sugar levels over time. The other choices, hypoglycemia and neuropathy (choice B), hypotension and kidney failure (choice C), and infection and fluid overload (choice D) are not typically the primary complications associated with untreated Type 1 diabetes.
