A nurse is collecting data from a client who has peripheral arterial disease (PAD). Which of the following findings should the nurse expect?

Choice A reason: Cough is not commonly associated with atenolol. Atenolol is a beta-blocker used to treat hypertension and is less likely to cause respiratory side effects compared to some other classes of antihypertensive medications.

Choice B reason: Bradycardia, or a slower than normal heart rate, is a well-documented adverse effect of atenolol. Atenolol works by blocking beta-1 receptors in the heart, which can reduce the heart rate. Normal heart rate ranges for infants (1 to 11 months old) are 80-160 beats per minute (BPM), and for toddlers (1-2 years old), it's 80-130 BPM. Bradycardia would be defined as a heart rate below these normal ranges. It is important for patients starting atenolol to monitor their pulse regularly and report any significant decrease in heart rate to their healthcare provider.

Choice C reason: While constipation can be a side effect of many medications, it is not a common adverse effect of atenolol. Atenolol does not typically affect the gastrointestinal system to the extent that it causes constipation.

Choice D reason: Headache is not a typical adverse effect of atenolol. While headaches can occur for a variety of reasons, they are not directly linked to the pharmacological action of atenolol on the cardiovascular system.

Choice A reason : The statement that warfarin dissolves clots in the bloodstream is incorrect. Warfarin does not dissolve existing clots. Instead, it is an anticoagulant that works by decreasing the production of certain clotting factors in the blood, which helps prevent the formation of new clots.

Choice B reason : This statement is not accurate regarding the action of warfarin. Warfarin does not affect the electrical impulses of the heart. Medications that slow the response of the ventricles to fast atrial impulses are typically antiarrhythmic drugs, not anticoagulants like warfarin.

Choice C reason : This is the correct statement. Warfarin is prescribed for clients with atrial fibrillation to reduce the risk of stroke. Atrial fibrillation increases the risk of forming blood clots in the heart, which can then travel to the brain, causing a stroke. Warfarin's anticoagulant effect helps to prevent these clots from forming.

Choice D reason : Warfarin does not help maintain a normal heart rhythm. It is not an antiarrhythmic drug but an anticoagulant. The purpose of warfarin in atrial fibrillation is to prevent stroke by reducing the risk of clot formation, not to correct the heart rhythm.
