Question 1 of 5
A nurse is teaching a client about the different types of angina. Which client statement indicate the need for follow up teaching?
Correct Answer: B
Rationale: Prinzmetal angina, also known as variant angina, is not typically associated with strenuous exercise. It is a type of angina that occurs at rest, often during the night or early morning hours. It is caused by a temporary spasm of the coronary arteries, leading to a decrease in blood flow to the heart muscle. Clients with Prinzmetal angina may experience chest pain, often with changes in the electrocardiogram (ECG) during an episode. Therefore, the client's statement about Prinzmetal angina occurring with strenuous exercise is incorrect and indicates the need for follow-up teaching.
Question 2 of 5
Which is true about the physiology of neuroendocrine compensatory mechanism?
Correct Answer: B
Rationale: The correct answer is B because the statement accurately reflects the physiology of the neuroendocrine compensatory mechanism. When there is a decrease in cardiac output, the body activates the sympathetic nervous system and releases catecholamines such as epinephrine and norepinephrine. These catecholamines help increase heart rate, contractility, and vasoconstriction to maintain blood pressure and perfusion to vital organs. This compensatory mechanism aims to overcome the decreased cardiac output and maintain adequate tissue perfusion in response to stress or reduced blood flow.
Question 3 of 5
A urine dipstick test reveals a trace amount of protein. The nurse identifies which nursing diagnosis as appropriate for the client at this time?
Correct Answer: A
Rationale: A trace amount of protein in the urine dipstick test can indicate proteinuria, which can be a sign of kidney dysfunction. The presence of protein in the urine may lead to fluid retention and potential imbalances in fluid volume. Therefore, the appropriate nursing diagnosis in this situation would be "Risk for Imbalanced Fluid Volume," as monitoring and management of fluid balance would be crucial for the client's overall health and prevention of further complications related to kidney function.
Question 4 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 5 of 5
The nurse is planning care for a client with a pulmonary embolism. Which nursing action would assist with the client's decrease in cardiac output?
Correct Answer: A
Rationale: Providing oxygen will help increase the oxygen supply to the tissues, thus supporting the heart in maintaining cardiac output. A decrease in cardiac output is a concern with pulmonary embolism as it can lead to inadequate tissue perfusion and possible complications. Oxygen therapy can improve oxygenation and support the heart in meeting the body's demands, helping to stabilize cardiac output. Monitoring and assessing pulmonary arterial pressures would be important in managing a pulmonary embolism but would not directly assist in increasing cardiac output. Keeping protamine sulfate at the bedside is more relevant for managing heparin overdose, not specifically for addressing a decrease in cardiac output. Assessing for bleeding is important in monitoring for potential complications of anticoagulant therapy but does not directly address the decrease in cardiac output seen in pulmonary embolism.
