Extract:
Question 1 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 2 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 3 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.
Question 4 of 5
While the nurse is providing preoperative teaching, the client says, 'I hate the idea of being an invalid after they cut off my leg.' The nurse's most therapeutic response should be:
Correct Answer: B
Rationale: The therapeutic response, 'Tell me more about how you're feeling,' encourages the client to express fears and concerns, facilitating emotional support and coping. The other responses dismiss the client's feelings, prioritize teaching, or make assumptions, which are less therapeutic.
Question 5 of 5
When instructing a client who has been newly diagnosed with vasospastic disorder (Raynaud's phenomenon) about management of care, the nurse should discuss which of the following topics?
Correct Answer: C
Rationale: Raynaud's phenomenon is often associated with connective tissue diseases (e.g., scleroderma, lupus), especially secondary Raynaud's. Discussing follow-up monitoring for these conditions is essential for early detection and management. Sympathectomy, beta blockers, and angioplasty are not first-line or relevant interventions.
