A nurse is caring for a newly admitted patient who will receive Digoxin to treat cardiac dysrhythmia.
The patient takes hydrochlorothiazide and reports regular use of OTC laxatives.
Before administering the first dose of Digoxin, the nurse will review the patient’s electrolyte levels with careful attention to which electrolytes?
Calcium and magnesium.
Potassium and chloride.
Potassium and magnesium.
Sodium and calcium.
The Correct Answer is C
Choice A rationale
Calcium and magnesium imbalances are less likely to influence Digoxin's effects compared to potassium and magnesium.
Choice B rationale
While chloride levels are important, potassium is more critical due to its significant impact on Digoxin’s action.
Choice C rationale
Correct, potassium and magnesium levels are crucial as imbalances can potentiate Digoxin toxicity or reduce its efficacy.
Choice D rationale
Sodium and calcium imbalances are less directly related to Digoxin efficacy compared to potassium and magnesium.

Correct Answer is A
Explanation
Choice A rationale
Parkinson's disease is characterized by an imbalance of dopamine and acetylcholine, primarily due to the degeneration of dopamine-producing neurons in the substantia nigra. This imbalance results in the characteristic motor symptoms of Parkinson's disease, such as tremors, rigidity, and bradykinesia.
Choice B rationale
Parkinson's disease involves decreased dopamine production, not increased. The disease is caused by the progressive loss of dopamine-producing neurons in the brain, leading to reduced dopamine levels and an imbalance with acetylcholine.
Choice C rationale
Alzheimer's disease is not primarily characterized by a decrease in dopamine. Instead, it involves the degeneration of cholinergic neurons and a deficiency in acetylcholine, which is crucial for memory and cognitive functions.
Choice D rationale
Alzheimer's disease is associated with a deficiency of acetylcholine rather than an excess. The disease is also characterized by the presence of neuritic plaques and neurofibrillary tangles in the brain, which contribute to cognitive decline.
Correct Answer is D
Explanation
Choice A rationale
Itching and rash are not common adverse effects associated with calcium-channel blockers. They are more commonly related to other classes of medications.
Choice B rationale
Hypertension and tachycardia are not typical adverse effects of calcium-channel blockers. These medications are usually prescribed to treat hypertension and can actually cause a reduction in heart rate.
Choice C rationale
Nausea and diarrhea are possible side effects of many medications, but they are not specific adverse effects commonly linked to calcium-channel blockers.
Choice D rationale
Headache and dizziness are common adverse effects of calcium-channel blockers. These medications can cause vasodilation, leading to headaches and a decrease in blood pressure, which may result in dizziness, especially when standing up quickly. .
