Correct Answer: A

Rationale: The best intervention for a patient with suspected deep vein thrombosis (DVT) is to administer anticoagulants. Anticoagulants help prevent further clot formation and reduce the risk of complications such as pulmonary embolism. Applying compression stockings can help manage symptoms but does not address the underlying issue of clot formation. Encouraging ambulation is beneficial for overall circulation but may not be sufficient to treat DVT. Monitoring oxygen saturation is important, but it is not the primary intervention for suspected DVT.

Correct Answer: A

Rationale: Administering IV fluids is the best intervention for a patient with dehydration because it is the fastest and most effective way to rehydrate the body. IV fluids can quickly restore fluid volume and electrolyte balance in severe cases of dehydration. Providing oral fluids or encouraging fluid intake may not be sufficient for patients with moderate to severe dehydration, as they may have impaired gastrointestinal absorption. While electrolytes are essential for rehydration, administering them alone without fluid replacement may not address the primary issue of fluid loss in dehydration.

Correct Answer: A

Rationale: In this scenario, the client is experiencing frequent contractions with a short duration and an elevated fetal heart rate, indicating potential fetal distress. Discontinuing the oxytocin infusion is crucial to prevent further complications and restore normal fetal parameters. Increasing or maintaining the oxytocin infusion could exacerbate the situation, leading to more distress for the fetus. Decreasing the oxytocin infusion may not be sufficient to address the current issue and could delay the improvement of fetal well-being.

Correct Answer: B

Rationale: When administering enoxaparin, it is important to pinch the skin to ensure proper subcutaneous injection. Massaging the injection site after administering the medication is not recommended. Administering the medication at bedtime is not a specific requirement for enoxaparin. Aspirating before injecting the medication is not necessary for subcutaneous injections like enoxaparin.

Correct Answer: D

Rationale: Clients diagnosed with tuberculosis should be placed in a negative pressure room to prevent the spread of airborne pathogens. Option A is incorrect because administering isoniazid is a treatment for tuberculosis, not a preventive measure related to infection control. Option B is incorrect as droplet isolation is used for diseases transmitted through respiratory droplets, not airborne pathogens like tuberculosis. Option C is incorrect as wearing a surgical mask is not sufficient to prevent the spread of tuberculosis in healthcare settings; placing the client in a negative pressure room is the most effective measure.
