A nurse is assessing a sedated client whose respiratory rate has fallen below 10 respirations per minute.
The nurse identifies this condition as what?
Tachypnea.
Apnea.
Bradypnea.
Eupnea.
The Correct Answer is A
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. .

Correct Answer is D
Explanation
The correct answer is Choice D.
Choice A rationale: Keeping the walker at the end of the bed is inconvenient and increases the risk of falls. The walker should be easily accessible, ideally placed near where the client gets up from bed, to provide immediate support.
Choice B rationale: Fluorescent ceiling lights can be too harsh and cause glare, making it difficult for the client to see properly at night. Instead, using a nightlight or a softer, dimmable light source is recommended to provide safe, clear visibility.
Choice C rationale: Placing an area rug at the entry of the bathroom poses a tripping hazard. Loose rugs can easily shift and cause falls. It's better to use non-slip mats or secure carpeting to ensure safe footing, especially in areas prone to moisture.
Choice D rationale: Using a bath seat in the shower reduces the risk of slipping and falling. It provides a stable and secure place to sit while bathing, which is particularly important for clients with a history of falls or limited mobility.
Correct Answer is A
Explanation
Choice A rationale:
"I will keep my walker at the end of my bed." This statement indicates that the client understands the importance of having the walker within reach. Placing the walker at the end of the bed ensures that the client can use it immediately upon getting up, providing support and stability, thus reducing the risk of falls.
Choice B rationale:
"I will keep the fluorescent ceiling light on in my room at night." While having adequate lighting is important, using a fluorescent ceiling light throughout the night might disrupt the client's sleep. Additionally, a nightlight or a bedside lamp with a low-wattage bulb can provide sufficient illumination without disturbing sleep.
Choice C rationale:
"I will place an area rug at the entry of my bathroom." This statement indicates a lack of understanding. Area rugs can be tripping hazards, especially in areas prone to moisture like bathrooms. It is advisable to remove rugs and ensure non-slip flooring to prevent slips and falls.
Choice D rationale:
"I will place a bath seat in my shower to use when I bathe." While using a bath seat is a good safety measure, it does not address the client's risk of falling outside the shower area. Installing grab bars and non-slip mats in the bathroom, along with removing potential hazards, would be more comprehensive in ensuring the client's safety. .
