Question 1 of 5
A client undergoes ligation of varicose veins. The nurse includes in the plan of care which of the following important interventions for the nursing diagnosis of ineffective tissue perfusion?
Correct Answer: B
Rationale: Step 1: Flexing the lower extremities helps promote blood circulation and prevents blood clot formation post-vein ligation. Step 2: Increased movement aids in preventing stasis and promotes tissue perfusion. Step 3: Flexing exercises can prevent complications such as deep vein thrombosis. Step 4: Removing compression stockings, numbness, and brisk scrubbing do not directly address tissue perfusion or circulation issues.
Question 2 of 5
A patient is admitted with severe uncompensated pulmonary edema secondary to chronic heart failure. After diagnostic testing, it is found that the left coronary artery is blocked, which has led to his pulmonary edema. Which of the following signs and symptoms is consistent with this diagnosis?
Correct Answer: C
Rationale: The correct answer is C: Elevated pulmonary artery wedge pressure (PAWP) or PAOP. In this scenario, the blockage in the left coronary artery is causing a decrease in cardiac output, leading to heart failure and pulmonary edema. Elevated PAWP indicates increased pressure in the left side of the heart, reflecting the back pressure that causes fluid to leak into the lungs. A: Elevated central venous pressure is more indicative of right heart failure, not directly related to left coronary artery blockage. B: Elevated blood pressure is not typically associated with pulmonary edema from left coronary artery blockage. D: Increased oxygen saturation would not be a typical finding in pulmonary edema due to decreased gas exchange in the lungs.
Question 3 of 5
A patient is being taught how to care for his pacemaker site by the critical care nurse. Which of the following indicates that this patient understands safe care of the device?
Correct Answer: A
Rationale: The correct answer is A because it demonstrates the patient's understanding of the importance of avoiding electromagnetic interference, which can disrupt the functioning of the pacemaker. Handling the pacemaker leads at the same time as the toaster can generate electromagnetic interference. Option B is incorrect because obtaining a medic alert tag is important for emergency identification but does not directly relate to pacemaker care. Option C is incorrect as the patient should always be vigilant about infection risks regardless of where the pacemaker was implanted. Option D is incorrect as modern pacemakers are designed to withstand low levels of microwave radiation and being around a home microwave is generally safe.
