Question 1 of 5
A nurse is planning care for a client who has worsening heart failure and is experiencing arrhythmias. Which of the following procedures should the nurse anticipate the client will require to regulate the rhythm?
Correct Answer: B
Rationale: Cardiac resynchronization therapy (CRT), also known as biventricular pacing, involves the placement of a specialized pacemaker device to improve the coordination of contractions between the heart's chambers. It is often used in patients with heart failure and arrhythmias to help regulate the rhythm and improve cardiac function.
Question 2 of 5
A nurse is assessing a client suspected of having cardiac tamponade. Which of the following findings indicates the presence of pulsus paradoxus?
Correct Answer: A
Rationale: Pulsus paradoxus is characterized by an exaggerated decrease in systolic blood pressure (>10 mm Hg) during inspiration, reflecting impaired cardiac output due to restricted ventricular filling, as seen in cardiac tamponade.
Question 3 of 5
A nurse is teaching a group of clients about the specific types of fluids that protect the structures of the inner ear. Which of the following statements should the nurse include in the teaching?
Correct Answer: A
Rationale: Endolymph is a fluid found within the membranous labyrinth of the inner ear. It plays a crucial role in maintaining the balance of ions necessary for proper sensory function of the auditory and vestibular systems. Endolymph helps protect the delicate sensory structures of the inner ear, including the hair cells responsible for hearing and balance.
Question 4 of 5
A nurse is assessing a client who has peripheral artery disease. Which of the following findings should the nurse recognize as requiring immediate intervention?
Correct Answer: B
Rationale: Pain, pallor, and paresthesia indicate critical limb ischemia, a severe complication of peripheral artery disease requiring immediate intervention to prevent tissue damage and limb loss.
Question 5 of 5
A nurse and a newly licensed nurse are providing care for a client who has distributive shock. How should the nurse explain the pathophysiology of distributive shock to the newly licensed nurse?
Correct Answer: C
Rationale: Distributive shock is caused by systemic vasodilation, leading to decreased systemic vascular resistance and inadequate tissue perfusion despite normal or high cardiac output.
