Up to one-third of patients who take ACE inhibitors for hypertension report which symptom after beginning therapy?
Decreased white blood cells.
Swelling of the face and lips.
Chronic cough.
Renal failure.
The Correct Answer is C
ACE inhibitors are a type of medication used to treat high blood pressure and heart failure. They work by blocking the production of a hormone called angiotensin II, which narrows the blood vessels and increases blood pressure. By preventing this hormone from acting, ACE inhibitors lower blood pressure and reduce the workload on the heart. One of the most common side effects of ACE inhibitors is a dry cough, which occurs in 12–19% of people who take them. The cough is caused by the accumulation of a substance called bradykinin, which is normally broken down by angiotensin-converting enzyme (ACE). When ACE is inhibited, bradykinin levels increase and cause irritation and inflammation in the airways.
Choice A is wrong because decreased white blood cells are not a common side effect of ACE inhibitors.
However, some people may develop a condition called neutropenia, which is a low level of a type of white blood cell called neutrophils. This can increase the risk of infections and may require stopping the medication.
Choice B is wrong because swelling of the face and lips is not a common side effect of ACE inhibitors.
However, some people may develop a rare but serious allergic reaction called angioedema, which is a swelling of the deeper layers of the skin and mucous membranes.
This can affect the face, lips, tongue, throat, or other parts of the body and can cause difficulty breathing or swallowing. Angioedema can be life-threatening and requires immediate medical attention.
Choice D is wrong because renal failure is not a common side effect of ACE inhibitors.
However, some people may experience a decrease in kidney function or an increase in blood levels of creatinine, which is a waste product filtered by the kidneys.

Correct Answer is A
Explanation
This is because digoxin inhibits the Na-K-ATPase pump on the membrane of cardiac cells, which can cause extracellular potassium levels to rise.Hypokalemia (low potassium) caused by large dosages of diuretics may result in digoxin toxicity even at low serum digoxin levels.Digoxin toxicity can cause gastrointestinal, constitutional, and/or cardiovascular symptoms, as well as ECG changes such as signs of increased automaticity and atrioventricular node blockade.
Choice B is wrong because calcium 9.2 mg/dL is within the normal range of 8.5 to 10.5 mg/dL.Hypercalcemia (high calcium) can increase sensitivity to digoxin effects and lead to toxicity even with a lower concentration of serum digoxin, but this is not the case here.
Choice C is wrong because potassium 4.8 mEq/L is within the normal range of 3.5 to 5.0 mEq/L.
Hyperkalemia (high potassium) can also increase the risk of digoxin toxicity, but this is not the case here.
Choice D is wrong because calcium 10.3 mg/dL is within the normal range of 8.5 to 10.5 mg/dL.Hypercalcemia (high calcium) can increase sensitivity to digoxin effects and lead to toxicity even with a lower concentration of serum digoxin, but this is not the case here.
Correct Answer is D
Explanation
Thiazide diuretics are sulfa-containing drugs and can cause allergic reactions in patients who are sensitive to sulfa compounds.These reactions can include headaches, rash, hives, swelling of the mouth and lips, wheezing or trouble breathing, asthma attack, and anaphylaxis.
Choice A is wrong because iodine is not a component of thiazide diuretics and is not related to sulfa allergy.
Choice B is wrong because latex is not a component of thiazide diuretics and is not related to sulfa allergy.
Choice C is wrong because shellfish is not a component of thiazide diuretics and is not related to sulfa allergy.
Shellfish allergy is usually caused by a protein called tropomyosin, not by iodine or sulfa compounds.
Thiazide diuretics are drugs that inhibit the reabsorption of sodium and water in the distal convoluted tubule of the kidney, leading to increased urine output.They are used to treat hypertension, edema, heart failure, and some kidney diseases.Some examples of thiazide diuretics are hydrochlorothiazide, chlorthalidone, and indapamide.
