Correct Answer: B

Rationale: The correct answer is to inject the medication into the lateral abdominal wall when administering enoxaparin. This is the recommended technique to ensure proper absorption and prevent tissue damage. Choice A is incorrect because enoxaparin should be administered subcutaneously, not intramuscularly. Choice C is incorrect as massaging the injection site after administration is not recommended, as it can cause bruising and discomfort. Choice D is incorrect because the prefilled syringe should not be discarded after expelling the air bubble; it should be used for the injection.

Correct Answer: A

Rationale: The correct answer is hypokalemia. Loop diuretics can cause potassium depletion leading to hypokalemia, which is particularly concerning as it can result in cardiac arrhythmias. Hyponatremia (choice B) is not typically associated with loop diuretics. Hyperkalemia (choice C) is less common in patients on loop diuretics. Hypercalcemia (choice D) is not a typical electrolyte imbalance associated with loop diuretics.

Correct Answer: C

Rationale: The correct action the nurse should implement is to apply sequential compression devices to the client's legs. This intervention helps prevent venous stasis and reduce the risk of deep vein thrombosis (DVT). Massaging the client's legs may dislodge a clot and is contraindicated in this situation (choice A). Encouraging bed rest may increase the risk of DVT due to prolonged immobility (choice B). While administering anticoagulants is a common treatment for DVT, in this case, the question is about preventive measures, and using sequential compression devices is a non-pharmacological approach.

Correct Answer: C

Rationale: The correct answer is a low-sodium diet. Patients with chronic kidney disease are often advised to follow a low-sodium diet to help manage fluid retention. Excessive sodium intake can lead to fluid buildup in the body, causing complications for individuals with kidney issues. Choices A and B are incorrect because while protein intake may need to be monitored in kidney disease, the primary focus is typically on sodium restriction. Choice D is incorrect as a high-sodium diet would exacerbate fluid retention in patients with chronic kidney disease.

Correct Answer: A

Rationale: The correct answer is to administer bronchodilators as the priority nursing action for a patient experiencing an acute asthma attack. Bronchodilators help open the airways and improve airflow, which is crucial in managing the acute respiratory distress in asthma. Corticosteroids may be used subsequently to reduce inflammation, but in the acute phase, bronchodilators take precedence. Providing supplemental oxygen is important but may not address the underlying bronchoconstriction characteristic of an asthma attack. Starting IV fluids is not a priority in managing an acute asthma attack unless indicated for specific reasons such as dehydration.
