A child has been diagnosed with rheumatic fever. Which statement by the mother indicates an understanding of rheumatic fever?

Correct Answer: A

Rationale: The correct answer is A, "I should avoid giving my child aspirin for the arthritic pain." Rheumatic fever can cause joint pain, and giving aspirin to a child with rheumatic fever can worsen the condition by increasing the risk of Reye's syndrome. Aspirin should be avoided, and acetaminophen can be used for pain relief. Choice B is incorrect because penicillin is prescribed to prevent recurrent streptococcal infections, not until the child is 20 years old. Choice C is incorrect because gown, gloves, and mask are not necessary for rheumatic fever, as it is not a highly contagious disease. Choice D is incorrect because siblings don't need to be kept away from the child with rheumatic fever.

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: 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: 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.
