Correct Answer: C

Rationale: The correct instruction to include when educating a client prescribed enoxaparin is to inject the medication once daily. Enoxaparin is typically administered via subcutaneous injection once daily, usually in the abdomen, to prevent blood clots.

Correct Answer: D

Rationale: Redness and warmth of the affected limb are classic signs of deep-vein thrombosis (DVT) due to inflammation and increased blood flow. These symptoms occur as a result of the blood clot obstructing normal blood flow and causing localized inflammation in the affected limb. Swelling of the affected limb, diminished peripheral pulses, and coolness are not typically associated with DVT. Swelling can be present but is often accompanied by the characteristic redness and warmth. Diminished pulses and coolness are more indicative of arterial insufficiency rather than venous thrombosis.

Correct Answer: D

Rationale: Ensuring the water seal chamber is filled to the prescribed level is essential for the chest tube's effective functioning. This maintains the integrity of the system, prevents air from entering the pleural space, and facilitates proper drainage. Stripping the drainage tubing, keeping the drainage system below the chest level, or clamping the chest tube during ambulation are not recommended practices and can lead to complications.

Correct Answer: B

Rationale: When caring for a client with a prescription for wound irrigation, the nurse should cleanse the wound from the center outward. This technique helps prevent the introduction of microorganisms into the wound, reducing the risk of contamination and promoting effective wound healing. By using a circular motion from the cleanest area to the least clean areas, debris and bacteria are moved away from the wound site, decreasing the chances of infection.

Correct Answer: A

Rationale: The correct answer is A because taking the pulse before administering digoxin is crucial as the medication can cause bradycardia. Monitoring the pulse helps in identifying any signs of bradycardia, a common side effect of digoxin. Options B, C, and D are incorrect. Taking digoxin with an antacid may interfere with its absorption. Doubling the dose if a dose is missed can lead to overdose and adverse effects. Avoiding bananas is not specifically related to digoxin therapy.
