Which of the following suggestions should the nurse include when conducting health teaching for clients with arterial insufficiency?

Correct Answer: A

Rationale: The correct answer is A because avoiding long periods of sitting and standing helps improve blood circulation in clients with arterial insufficiency. Prolonged sitting or standing can worsen arterial insufficiency by restricting blood flow. Keeping the legs and feet in a raised position (choice B) can help reduce swelling but does not address the root issue of poor circulation. Decreasing ambulation (choice C) would further compromise circulation. Applying moist heat (choice D) can be detrimental as it can dilate blood vessels and exacerbate arterial insufficiency symptoms.

Correct Answer: C

Rationale: The correct answer is C because placing electrodes with contacts on their anterior and posterior surfaces ensures good conduction of electricity from the heart to the monitor. This placement maximizes the contact area with the skin, leading to better signal transmission. Choice A is incorrect because changing electrode pads periodically may help maintain skin integrity but does not directly impact electrical conduction. Choice B is incorrect as ribs are not good conductors of electricity. Choice D is incorrect as placing electrodes further apart may lead to decreased signal quality and interference.

Correct Answer: A

Rationale: The correct answer is A: Phenylephrine (Neo-Synephrine). Phenylephrine is a potent vasoconstrictor that can increase blood pressure, making it effective in managing mild to moderate hypotension. It works by stimulating alpha-adrenergic receptors, leading to vasoconstriction and increased peripheral vascular resistance, ultimately raising blood pressure. Other choices are incorrect: B: Amiodarone is an antiarrhythmic drug used to treat irregular heart rhythms, not hypotension. C: Ibutilide is a class III antiarrhythmic agent used for maintaining normal heart rhythm, not for managing hypotension. D: Milrinone is a phosphodiesterase inhibitor that increases cardiac contractility and vasodilation, primarily used in heart failure, not specifically for managing hypotension.

Correct Answer: A

Rationale: The correct answer is A because chest pain relieved by nitroglycerin is a classic symptom of stable angina, indicating a temporary lack of oxygen to the heart muscle. This distinguishes it from MI pain, which is not typically relieved by nitroglycerin. Choices B, C, and D are incorrect because they are not specific to stable angina and can also be present in MI pain. Choice B is a common symptom for both conditions, choice C describes radiation patterns seen in both conditions, and choice D is a trigger for both stable angina and MI pain.

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.
