Extract:
Question 1 of 5
A 70-year-old female is scheduled to undergo mitral valve replacement for severe mitral stenosis and mitral regurgitation. Although the diagnosis was made during childhood, she did not have symptoms until 4 years ago. Recently, she noticed increased symptoms, despite daily doses of digoxin and furosemide. During the initial interview with the client, the nurse would most likely learn that the client's childhood health history included:
Correct Answer: C
Rationale: Rheumatic fever in childhood is a common cause of mitral valve disease, leading to stenosis or regurgitation later in life.
Question 2 of 5
When teaching a client about propranolol hydrochloride, the nurse should base the information on the knowledge that propranolol:
Correct Answer: A
Rationale: Propranolol, a beta-blocker, blocks beta-adrenergic receptors, reducing heart rate, contractility, and conduction, lowering blood pressure.
Question 3 of 5
When performing external chest compressions on an adult during cardiopulmonary resuscitation (CPR), the rescuer should depress the sternum:
Correct Answer: C
Rationale: Depressing the sternum 1.5 to 2 inches ensures adequate compression depth for effective CPR in adults, per guidelines.
Question 4 of 5
Peripheral blood flow is dependent on which of the following variables?
Correct Answer: D
Rationale: Peripheral blood flow depends on pressure differences between the arterial and venous systems (driving force) and vascular resistance (opposing force). This relationship is governed by Poiseuille's law and Ohm's law for fluid flow, where flow is proportional to the pressure gradient and inversely proportional to resistance. The other options are incomplete or incorrect combinations of factors.
Question 5 of 5
When assessing an individual with peripheral vascular disease, which clinical manifestation would indicate complete arterial obstruction in the lower left leg?
Correct Answer: D
Rationale: Complete arterial obstruction causes severe ischemia, leading to coldness of the affected limb (foot and ankle) due to absent blood flow. Aching or burning pain and numbness/tingling suggest partial occlusion or neuropathy, not complete obstruction.
