LPN Fundamentals of Nursing

Correct Answer: B

Rationale: When a pressure ulcer is healing, there is a decrease in its size as the tissue repair progresses. This reduction in size is a positive indication of the healing process. An increase in drainage, presence of foul odor, or reddened wound edges are typically signs of infection or lack of improvement. Therefore, the correct answer is a decrease in size.

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.

Correct Answer: B

Rationale: When using a cane, it is crucial to move the cane forward first to provide support and enhance balance. Advancing the cane before the weaker or stronger leg helps widen the base of support, thereby improving stability during ambulation. Keeping the cane too far or too close to the body can affect its supportive function. Moreover, utilizing the cane solely for stair climbing limits its overall utility in maintaining balance and stability during regular walking.

Correct Answer: B

Rationale: Keeping the bed in the lowest position is crucial for ensuring the safety of the client during a seizure. Lowering the bed reduces the risk of injury if the client falls during a seizure episode. It is important not to restrain the client during a seizure as it can lead to further injury. Placing a padded tongue depressor at the bedside is not appropriate and can pose a risk of injury if used incorrectly. Keeping the lights dim in the client's room is not directly related to safety during a seizure and is not a standard precaution.

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.
