Question 1 of 5
Which property of cardiac cells is mechanical in nature?
Correct Answer: D
Rationale: Contractility is the property of cardiac cells that is mechanical in nature. It refers to the ability of cardiac muscle cells to contract in response to an electrical stimulus. This contraction is what enables the heart to pump blood throughout the body. Contractility is essential for maintaining cardiac output and overall cardiovascular function. While automaticity, excitability, and conductivity are also important properties of cardiac cells, they are primarily related to the electrical activity of the heart rather than the mechanical function of contraction.

Question 3 of 5
A patient recovering from a partial nephrectomy is in the post-anesthesia care unit. Which interventions would be a priority for the patient? Select all that apply.
Correct Answer: B
Rationale: - Labeling and securing all catheters, tubes, and drains (Choice B) is a priority intervention as it ensures proper monitoring and identification of the postoperative devices. By keeping these items labeled and secure, healthcare providers can prevent accidental dislodgement or confusion, leading to improved patient safety and management.
Question 4 of 5
The nurse reviews documentation on a patient with a long leg cast for a fracture in which the pulses in the foot were decreased and the patient was experiencing a pain rating of 8 on a scale of 0 to 10 during the previous shift. Which additional findings should the nurse immediately report to the healthcare provider? Select all that apply.
Correct Answer: C
Rationale: Cyanosis in the foot indicates poor circulation or decreased blood flow to the area, which is concerning in a patient with a long leg cast and decreased pulses. This could signify a significant decrease in oxygenated blood reaching the foot, which could lead to serious complications if not addressed promptly. The nurse should report this finding immediately to the healthcare provider for further assessment and intervention.
Question 5 of 5
The nurse is analyzing data collected after assessing a child with a congenital heart defect that decreases pulmonary blood flow. Which nursing diagnosis would be applicable for this client?
Correct Answer: C
Rationale: A congenital heart defect that decreases pulmonary blood flow can lead to reduced cardiac output. Cardiac output is the amount of blood pumped by the heart per minute, and a decrease in pulmonary blood flow can affect the heart's ability to effectively pump blood to the body. Therefore, the appropriate nursing diagnosis for this client would be Decreased Cardiac Output. This diagnosis reflects the underlying physiological issue caused by the congenital heart defect and guides the nurse in planning appropriate interventions to support and optimize the child's cardiac function.
