Which of the following is a sign of digoxin toxicity?

Correct Answer: A

Rationale: The correct answer is A, Bradycardia. Bradycardia, or a slower than normal heart rate, is a classic sign of digoxin toxicity. Digoxin is a medication commonly used to treat heart conditions, but an excess of digoxin in the body can lead to toxicity. This toxicity can manifest as various symptoms, with bradycardia being one of the most common ones. Hypertension (high blood pressure) and tachycardia (fast heart rate) are not typical signs of digoxin toxicity. Tachypnea, which refers to rapid breathing, is also not a common sign of digoxin toxicity.

Correct Answer: A

Rationale: The correct answer is A: 'To reduce nausea and vomiting.' Antiemetics are medications used to prevent or alleviate nausea and vomiting. While they may indirectly help with appetite by reducing the unpleasant symptoms that can lead to decreased food intake, their primary purpose is not to increase appetite (Choice B). Choice C, 'To treat nausea caused by chemotherapy,' is partly correct as antiemetics are commonly used to manage chemotherapy-induced nausea, but this is not their exclusive purpose. Choice D, 'To treat allergic reactions,' is incorrect as antiemetics are not primarily used for treating allergic reactions.

Correct Answer: B

Rationale: Providing oral glucose is the correct intervention for a patient experiencing hypoglycemia. Oral glucose helps quickly raise blood sugar levels, making it the preferred treatment for mild hypoglycemia. Administering glucagon (Choice A) is usually reserved for severe cases when the patient cannot take anything by mouth. Administering IV fluids (Choice C) is not the primary intervention for hypoglycemia unless the patient is severely dehydrated. Monitoring blood sugar levels (Choice D) is important but providing glucose is the immediate priority to treat hypoglycemia.

Correct Answer: A

Rationale: The correct answer is to monitor serum creatinine. In patients with chronic kidney disease, monitoring serum creatinine is crucial as it reflects kidney function. This assessment helps healthcare providers in evaluating the progression of the disease and adjusting treatment plans accordingly. Monitoring blood pressure (choice B) is essential in managing chronic kidney disease, but monitoring serum creatinine takes precedence. Monitoring urine output (choice C) and potassium levels (choice D) are also important aspects of managing chronic kidney disease, but they are not the priority assessment compared to monitoring serum creatinine.

Correct Answer: A

Rationale: Furosemide is the correct answer. It is a common diuretic used in patients with heart failure to reduce fluid overload. Metoprolol (Choice B) is a beta-blocker often prescribed to manage heart failure symptoms by improving heart function. Digoxin (Choice C) is used in heart failure patients to help the heart beat stronger and with a more regular rhythm. Aspirin (Choice D) is not typically prescribed for heart failure but may be used in patients with heart disease for its antiplatelet effects.
