Which of the following anti-hypertensive medication belongs to the ACE Inhibitors?
Lisinopril.
Candesartan.
Metoprolol.
Amlodipine.
The Correct Answer is A
Lisinopril belongs to the class of drugs called angiotensin-converting enzyme (ACE) inhibitors. ACE inhibitors work by blocking the enzyme that converts angiotensin I to angiotensin II, a hormone that causes blood vessels to narrow and raise blood pressure. By inhibiting this enzyme, ACE inhibitors relax and widen the blood vessels, lower blood pressure, and improve blood flow to the heart and kidneys.
Choice B. Candesartan is wrong because it belongs to the class of drugs called angiotensin II receptor blockers (ARBs). ARBs work by blocking the action of angiotensin II on its receptors, preventing it from causing blood vessel constriction and high blood pressure. ARBs are similar to ACE inhibitors in their effects, but they do not affect the enzyme or the level of bradykinin, a peptide that can cause cough and angioedema as side effects of ACE inhibitors.
Choice C. Metoprolol is wrong because it belongs to the class of drugs called beta blockers. Beta blockers work by blocking the effects of adrenaline and other hormones that stimulate the heart and blood vessels, causing them to beat slower and with less force. Beta blockers lower blood pressure and reduce the workload on the heart.
Choice D. Amlodipine is wrong because it belongs to the class of drugs called calcium channel blockers. Calcium channel blockers work by blocking the entry of calcium into the muscle cells of the heart and blood vessels, causing them to relax and dilate. Calcium channel blockers lower blood pressure and improve blood flow to the heart.
Normal ranges for blood pressure vary depending on age, gender, and other factors, but generally, a systolic blood pressure (the top number) of less than 120 mmHg and a diastolic blood pressure (the bottom number) of less than 80 mmHg are considered normal for adults. A blood pressure of 130/80 mmHg or higher is considered high and may require treatment with medication.

Correct Answer is D
Explanation
According to the International Society of Hypertension, lifestyle interventions are recommended for three to six months before medication in patients with grade 1 hypertension (BP < 160/100 mm Hg) and no comorbidities.Diet and exercise can lower BP by reducing weight, sodium intake, alcohol consumption, and stress levels.
Choice A is wrong because angiotensin-converting enzyme (ACE) inhibitors are not the first-line medication for hypertension in the general population.They are preferred in patients with diabetes, chronic kidney disease, or heart failure.
Choice B is wrong because combination diuretics are not the initial recommendation for hypertension.They are used when monotherapy is not sufficient to achieve the target BP or when there is fluid retention.
Choice C is wrong because beta-adrenergic blocking agents are not the first-line medication for hypertension in the general population.They are preferred in patients with ischemic heart disease, heart failure, or arrhythmias.
Correct Answer is A
Explanation
Digoxin is a medication that can help the heart pump more blood and slow down the heart rate in certain conditions, such as heart failure and atrial fibrillation.However, digoxin has a narrow therapeutic range, which means that too much or too little of it can be harmful.The therapeutic range of digoxin levels in the blood is 0.5-2 ng/mL, and the toxic level is >2.4 ng/mL.Digoxin should be held if the resting apical pulse of an infant is <90 bpm, an older child is <70 bpm, or an adult is <60 bpm.A pulse of 48/min in an adult is too low and could indicate digoxin toxicity, which can cause life-threatening arrhythmias. Therefore, the nurse should withhold the dose and notify the health care provider immediately.
Choice B is wrong because notifying the health care provider and monitoring the patient’s vital signs are not enough.
The nurse should also withhold the dose to prevent further exposure to digoxin.
Choice C is wrong because rechecking the pulse, making sure to count for 1 full minute, is not necessary.The nurse should already have counted the pulse for 1 full minute before administering digoxin, as per standard procedure.
Choice D is wrong because administering the dose could worsen the patient’s condition and increase the risk of digoxin toxicity and arrhythmias.
