Vomiting

Headache

E.

Muscle aches

Answer and Explanation

Correct Answer : A,B,C

A) Vomiting:
Vomiting is a common symptom of digoxin toxicity. It occurs as a result of the toxic effects of digoxin on the gastrointestinal system. It is often one of the first symptoms that precede more severe signs of toxicity, such as arrhythmias and changes in vision. Vomiting, nausea, and anorexia are classic early signs of digoxin toxicity.

B) Nausea:
Nausea is another early sign of digoxin toxicity. It occurs due to the direct effects of the drug on the gastrointestinal tract and the central nervous system. Along with vomiting, nausea is a frequently observed symptom and often occurs before more severe manifestations like arrhythmias or confusion.

C) Blurred Vision:
Blurred vision, or seeing yellow or green halos around lights, is a hallmark sign of digoxin toxicity. This visual disturbance occurs due to the effect of digoxin on the optic nerve and the retina. This symptom is particularly important in identifying digoxin toxicity, as it is not commonly seen in other conditions.

D) Headache:
While headache may occur in a variety of clinical conditions, it is not typically a direct symptom of digoxin toxicity. Although some patients may experience headache due to general discomfort or the effects of vomiting and nausea, it is not a classic or primary indicator of digoxin toxicity. Therefore, headache is not as strongly associated with digoxin toxicity as vomiting, nausea, and blurred vision are.
E) Muscle aches: 
Muscle aches are not a typical symptom of digoxin toxicity. While generalized weakness may occur due to the cardiac effects of digoxin, muscle aches are not specifically associated with toxicity.

Correct Answer is B

Explanation

A) Cardizem:
Cardizem (diltiazem) is a calcium channel blocker. Calcium channel blockers work by inhibiting the entry of calcium into the smooth muscle cells of the heart and blood vessels, which helps relax the blood vessels and lower blood pressure.

B) Labetalol:
Labetalol is a beta blocker and an alpha-1 blocker. It works by blocking both beta-adrenergic receptors (which help decrease heart rate and blood pressure) and alpha-1 receptors (which cause vasodilation). This dual action makes labetalol effective in treating high blood pressure, especially in patients with conditions like hypertension and hypertensive emergencies. It reduces heart rate and helps relax blood vessels, improving blood flow.

C) Losartan:
Losartan is an angiotensin II receptor blocker (ARB). ARBs work by blocking the effects of angiotensin II, a hormone that causes blood vessels to constrict. By blocking this effect, losartan helps lower blood pressure and is used in the treatment of hypertension and heart failure.

D) Simvastatin:
Simvastatin is a statin, which is a medication used to lower cholesterol levels. Statins work by inhibiting an enzyme involved in cholesterol production in the liver. They are used primarily to manage high cholesterol and reduce the risk of heart disease, but they do not have an effect on heart rate or blood pressure, unlike beta blockers.

Correct Answer is B

Explanation

Given:
Volume of fluid: 50 mL
Infusion time: 1 hour (60 minutes)
Drop factor: 15 gtt/mL

Formula:
Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL)

Step 1: Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Volume (mL) / Time (min)
Infusion rate (mL/min) = 50 mL / 60 min
Infusion rate (mL/min) = 0.83 mL/min

Step 2: Calculate the flow rate in gtt/min:
Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)
Flow rate (gtt/min) = 0.83 mL/min x 15 gtt/mL
Flow rate (gtt/min) = 12.5 gtt/min

Step 3: Round to the nearest whole number:
Flow rate (gtt/min) ≈ 13 gtt/min
