The nurse observes a PAWP waveform on the monitor when the balloon of the catheter is deflated. The nurse recognizes that

Correct Answer: D

Rationale: The correct answer is D because observing a PAWP waveform when the balloon of the catheter is deflated indicates improper positioning of the catheter. If the catheter is not properly positioned, it can lead to inaccurate pressure readings and pose a risk for complications such as pulmonary infarction or pulmonary artery rupture. Repositioning the catheter immediately is crucial to ensure accurate monitoring and prevent potential harm to the patient. A: This choice is incorrect because the presence of a PAWP waveform does not necessarily indicate occlusion of the catheter with a thrombus. B: This choice is incorrect because the development of pulmonary edema would typically result in a different waveform pattern, not specifically a PAWP waveform. C: This choice is incorrect because the risk of an air embolism is not directly related to observing a PAWP waveform when the catheter is deflated.

Correct Answer: C

Rationale: The correct answer is C because baroreceptors sense changes in blood pressure and send signals to the brain. When blood pressure is high, baroreceptors signal the brain to decrease heart rate via the parasympathetic nervous system. When blood pressure is low, baroreceptors signal the brain to increase heart rate via the sympathetic nervous system. This regulatory mechanism helps maintain blood pressure within a normal range. Choice A is incorrect because it does not mention the role of baroreceptors in sensing blood pressure changes. Choice B is incorrect because it does not explain the specific mechanism by which baroreceptors regulate heart rate. Choice D is incorrect because it does not address the involvement of the brain in the regulation of heart rate by baroreceptors.

Correct Answer: A

Rationale: The correct answer is A because older adults with heart and blood vessel diseases are more susceptible to thrombophlebitis due to reduced mobility, which can lead to blood pooling and clot formation in the veins. Reduced mobility can result from various reasons such as age-related muscle weakness, joint stiffness, and overall frailty. This stagnant blood flow increases the risk of clot formation, especially in the lower extremities. Choice B is incorrect because it contradicts the concept of reduced mobility in older adults. Choice C is incorrect as the use of IV drugs and chemicals is not directly linked to thrombophlebitis in this context. Choice D is incorrect as diet restrictions, although important for cardiovascular health, do not directly contribute to the susceptibility of thrombophlebitis in older adults with heart and blood vessel diseases.

Correct Answer: D

Rationale: The correct answer is D: Cerebral emboli may occur. After a TMR procedure, there is a risk of small blood clots (emboli) forming and traveling to the brain, leading to potential neurological complications. Assessing the client's mental status can help detect any signs of cerebral emboli, such as confusion or altered consciousness. Summary: A: Cerebral hemorrhage is not a common complication of TMR. B: Severe headache is not specific to cerebral emboli. C: Loss of consciousness can occur due to various reasons post-TMR, but it is not directly related to cerebral emboli.

Correct Answer: B

Rationale: Correct Answer: B Rationale: 1. Teaching about non-pharmacologic and pharmacologic BP management is essential for client empowerment and adherence. 2. Education on lifestyle changes and medications helps clients make informed decisions. 3. Assessing knowledge levels enables tailored interventions for optimal BP control. Summary: A: Monitoring temperature in different positions is not directly related to assessing hypertension. C: Taking BP in multiple positions is important for orthostatic hypotension assessment, not primary hypertension evaluation. D: Weighing the client daily does not directly address hypertension assessment or management.
