Which assessment finding by the nurse caring for a patient receiving mechanical ventilation indicates the need for suctioning?
The patient has occasional audible expiratory wheezes.
The patient's respiratory rate is 32 breaths/min
The patient was last suctioned 6 hours ago.
The patient's oxygen saturation drops to 93%.
The Correct Answer is D
D. A drop in oxygen saturation may indicate inadequate oxygenation, which could be due to airway obstruction or retained secretions.
A. While audible expiratory wheezes may indicate airway obstruction or secretions, they do not necessarily indicate the need for suctioning in a patient receiving mechanical ventilation.
B. An elevated respiratory rate may suggest increased work of breathing, which could be due to retained secretions or airway obstruction. However, an elevated respiratory rate alone may not always indicate the need for suctioning.
C. The timing of the last suctioning episode is an important consideration when determining the need for suctioning. However, it should not be the sole indicator for when to suction.

Correct Answer is ["A","B","C","D","E"]
Explanation
First, the nurse should open the airway using a jaw-thrust maneuver (C) to ensure it is not obstructed. Next, they should determine the effectiveness of ventilatory efforts (B), as breathing is critical and any compromise must be addressed immediately. Following this, establishing IV access (D) is important for fluid resuscitation and medication administration. The nurse should then perform a Glasgow Coma Scale assessment (E) to determine the level of consciousness and neurological function. Lastly, removing clothing for a thorough assessment (A) is essential, but only after the critical steps concerning airway, breathing, circulation, and disability have been addressed.
Correct Answer is ["B","C"]
Explanation
B. stroke volume is the amount of blood ejected from the left ventricle with each contraction (systole) of the heart. Changes in stroke volume directly affect cardiac output. An increase in stroke volume leads to an increase in cardiac output, while a decrease in stroke volume results in a decrease in cardiac output. Factors that can affect stroke volume include preload, afterload, and contractility of the heart.
C. Heart rate refers to the number of heartbeats per minute. Heart rate directly affects cardiac output by determining how frequently the heart contracts and pumps blood. An increase in heart rate (tachycardia) leads to an increase in cardiac output, while a decrease in heart rate (bradycardia) results in a decrease in cardiac output. Factors such as sympathetic and parasympathetic nervous system activity, hormones, and medications can influence heart rate.
A. Respiratory rate does not directly affect stroke volume or heart rate but changes in respiratory rate can indirectly impact cardiac output through their effects on venous return and preload.
D. Blood pressure represents the force exerted by the blood against the walls of the arteries. While blood pressure does not directly affect cardiac output, it is influenced by cardiac output and systemic vascular resistance (SVR).
