A 75-year-old individual is admitted with a diagnosis of left-sided heart failure and is administered Lasix 80 mg by slow IV push. Which nursing assessment indicates that the Lasix (furosemide) is NOT having the desired effect?

Correct Answer: A

Rationale: The correct answer is A: Oliguria. Oliguria is the decreased urine output, which is an indicator of inadequate response to Lasix in heart failure. Lasix is a diuretic used to reduce fluid overload in heart failure by promoting diuresis. In this case, a decrease in urine output suggests that the medication is not effectively removing excess fluid. For the other choices: B: Decrease in blood pressure - This could be an expected effect of Lasix as it helps reduce fluid volume and can lead to a decrease in blood pressure. C: Absence of crackles - This indicates reduced pulmonary congestion, which is a desired effect of Lasix in heart failure. D: Polydipsia - Increased thirst (polydipsia) is not directly related to the effectiveness of Lasix in treating heart failure. In summary, the presence of oliguria indicates inadequate response to Lasix, while the decrease in blood pressure, absence of crackles, and polydips

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.

Correct Answer: B

Rationale: The correct answer is B because it demonstrates active listening and encourages the patient to express their reasoning, which helps in understanding their perspective. By asking the patient to explain why they don't feel the need for lifestyle changes, it opens up dialogue and allows for exploration of their beliefs and concerns. This approach can uncover underlying issues, provide insight into their readiness for change, and guide the conversation towards addressing their specific barriers or misconceptions. Choice A is incorrect as it assumes the family's desires without directly addressing the patient's concerns. Choice C jumps to conclusions about the patient's denial stage without exploring their thoughts. Choice D is directive and may come across as dismissive of the patient's autonomy and readiness for change.
