LPN Fundamentals of Nursing

Correct Answer: C

Rationale: Aspirating before injecting the medication is a crucial step in IM injections to check for blood return, ensuring that the needle is not in a blood vessel. This technique helps prevent accidental intravascular injection of the medication, reducing the risk of complications such as inadvertent intravenous administration of the substance.

Correct Answer: B

Rationale: Pallor is a common finding in clients with anemia due to decreased hemoglobin levels. Anemia leads to reduced oxygen-carrying capacity in the blood, resulting in pale skin and mucous membranes, which is known as pallor. Bradycardia, hypertension, and jaundice are typically not associated with anemia.

Correct Answer: B

Rationale: Elevating the head of the bed to 30-45 degrees during feedings is essential to prevent aspiration in clients receiving enteral nutrition. This positioning helps decrease the risk of regurgitation and aspiration by supporting proper digestion and aiding food passage through the gastrointestinal tract. Elevating the head of the bed is a standard precautionary measure recommended to reduce the chances of aspiration and should be consistently implemented during feedings to ensure client safety and optimal enteral nutrition delivery.

Correct Answer: D

Rationale: Repositioning the client every 2 hours is crucial in preventing pressure ulcers from worsening. This action helps relieve pressure on specific areas, improving circulation and reducing the risk of tissue damage. Massaging the reddened area can further damage the skin, applying heat can increase the risk of skin breakdown, and elevating the head of the bed to 45 degrees may not directly address the pressure ulcer prevention. Proper positioning is essential to avoid prolonged pressure on the affected areas and promote healing.

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.
