Choice A rationale:

Diastolic pressure represents the pressure in the arteries when the heart is at rest between contractions. It specifically measures the force of blood against the arterial walls when both the atria and ventricles are relaxed, allowing the heart to fill with blood. Diastolic pressure is the bottom number in a blood pressure reading (e.g., 120/80 mmHg), indicating the pressure in the arteries during the heart's resting phase. Elevated diastolic pressure is an important indicator of increased risk for cardiovascular diseases, such as hypertension.

Choice B rationale:

This statement describes systolic blood pressure, which measures the pressure in the arteries when the heart's ventricles contract and pump blood into the circulation. Systolic pressure is the top number in a blood pressure reading (e.g., 120/80 mmHg) and represents the highest pressure reached in the arteries during a cardiac cycle.

Choice C rationale:

This description is not accurate for either diastolic or systolic pressure. Both atria and ventricles do not contract simultaneously; they follow a specific sequence to ensure effective pumping of blood through the heart.

Choice D rationale:

This statement is incorrect as it does not align with the definitions of diastolic or systolic blood pressure. Diastolic pressure specifically measures the pressure in the arteries during the heart's resting phase, not when the ventricles relax. .

Choice A rationale:

Tying the straps of the restraints in a double knot is incorrect. This action can make it difficult to quickly release the restraints in case of an emergency. A single, quick-release knot is recommended to ensure the client's safety.

Choice B rationale:

Tying the restraints to the side rails is incorrect. Attaching restraints to the side rails can cause injury to the client and is not a proper restraint application method. Restraints should be tied to the bed frame, not the side rails, to prevent harm.

Choice C rationale:

Placing the padding of the restraints against the client's bony prominences is incorrect. While padding is important to prevent skin breakdown and pressure ulcers, the correct placement of the padding alone does not indicate a comprehensive understanding of proper restraint application.

Choice D rationale:

Inserting one finger between the client's wrist and the restraint is the correct action. This technique ensures that the restraints are not too tight, allowing for proper circulation and preventing injury to the client. The ability to insert one finger indicates that the restraints are snug but not constrictive, maintaining the client's safety and comfort.
