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
Choice A rationale:
Ears are located on the sides of the head, not between the cranial and thoracic cavities. The ears are lateral structures on the head.
Choice B rationale:
Elbow is a joint located in the upper limb, specifically in the arm. It is not between the cranial and thoracic cavities. The elbow is a joint that allows the forearm to bend.
Choice C rationale:
Knee is a joint in the lower limb, connecting the thigh bone to the shin bone. It is not located between the cranial and thoracic cavities. The knee joint allows for movements like bending and straightening of the leg.
Choice D rationale:
The nape of the neck refers to the back of the neck. It is the posterior part of the neck, located between the cranial (head) and thoracic (upper chest) cavities. The nape of the neck is a specific anatomical location.
Correct Answer is A
Explanation
The correct answer is A. Instruct the clients to use the call light.
Choice A rationale:
Instructing clients to use the call light ensures they can request assistance before getting up, which is a key strategy in preventing falls, especially during the night when visibility is reduced and the risk of disorientation is higher.
Choice B rationale:
Keeping the clients' rooms dark can increase the risk of falls as it makes it difficult for clients to see obstacles and navigate their environment safely. Adequate lighting is important for fall prevention.
Choice C rationale:
Moving overbed tables away from the bed can actually make it harder for clients to reach essential items and might increase the risk of falls if clients have to stretch or lean awkwardly to get what they need. The overbed table should be positioned within easy reach.
Choice D rationale:
Performing client checks every 4 hours is not frequent enough to effectively monitor at-risk clients. More frequent checks, such as hourly, are recommended to ensure safety and promptly address any needs that could prevent a fall.
