Question 1 of 5
Blood pressure is influenced by all except which factor?
Correct Answer: C
Rationale: Blood pressure is influenced by the pumping action of the heart, peripheral vascular resistance, and blood volume. The heart rate, although related to the pumping action of the heart, is not a direct determinant of blood pressure. Heart rate can affect blood pressure indirectly through its impact on cardiac output, but it is not a primary factor influencing blood pressure regulation. Factors such as the amount of blood pumped by the heart (stroke volume), the elasticity of blood vessels, and the volume of blood in the circulatory system (blood volume) have more direct and significant effects on blood pressure regulation.
Question 2 of 5
The nurse is teaching a client about the associated health risks of cocaine use. Which statement should the nurse use to describe how cocaine can cause myocardial infarction (MI)?
Correct Answer: C
Rationale: Cocaine causes myocardial infarction (MI) primarily by increasing sympathetic nervous system stimulation. When a person uses cocaine, it leads to an excessive release of catecholamines, such as norepinephrine and epinephrine. These catecholamines cause an increase in heart rate, blood pressure, and vasoconstriction. The increased workload on the heart, combined with the reduced oxygen supply due to vasoconstriction, can lead to myocardial ischemia and potentially result in a myocardial infarction. Thus, the significant impact of cocaine on the sympathetic nervous system is the primary mechanism by which it can cause MI.
Question 3 of 5
A client with disseminated intravascular coagulation (DIC) is anxious and has decreased oxygen saturation. Which is the priority nursing diagnosis for this client?
Correct Answer: B
Rationale: In a client with disseminated intravascular coagulation (DIC) who is anxious and has decreased oxygen saturation, the priority nursing diagnosis is Impaired Gas Exchange. DIC can lead to microvascular thrombosis and bleeding, which can affect oxygenation at the cellular level. The client's decreased oxygen saturation indicates a problem with gas exchange, which is crucial for the delivery of oxygen to tissues and the removal of carbon dioxide. Prioritizing this issue is essential to prevent complications related to poor tissue oxygenation, such as organ dysfunction. Addressing the client's anxiety would also be important, but ensuring adequate gas exchange takes precedence to maintain tissue perfusion and oxygenation.
Question 4 of 5
When planning care for this client, which does the nurse understand about systolic heart failure?
Correct Answer: A
Rationale: Systolic heart failure is characterized by the inability of the heart to effectively contract and pump out an adequate amount of blood to meet the body's demands. This results in a decrease in the ejection fraction, which is the percentage of blood ejected from the ventricle with each heartbeat. The ventricle's inadequate contraction leads to diminished cardiac output, resulting in symptoms such as fatigue, dyspnea, and decreased exercise tolerance. Therefore, understanding that systolic heart failure is primarily due to the inadequate contraction of the ventricle is crucial in planning care for clients with this condition.
Question 5 of 5
The nurse is providing postpartum care for a client who gave birth by cesarean section several hours ago. The client had preeclampsia during the last 3 weeks of pregnancy. Which interventions are appropriate for this client within the first 48 hours after birth? Select all that apply.
