Correct Answer: A

Rationale: The best response is "Your risk of continued coronary artery disease will decrease by half when you stop." This response provides a specific and concrete benefit of quitting smoking for the client with a history of myocardial infarction. By explaining that quitting smoking can reduce the risk of continued coronary artery disease by half, the nurse is providing motivation and encouragement for the client to make a positive change in their lifestyle. This information is factual and can help the client understand the immediate benefits of quitting smoking in relation to their current health condition.

Correct Answer: A

Rationale: A. Excessive sweating: Children with congestive heart failure (CHF) may experience excessive sweating as their bodies work harder to keep up with the demands of the heart, leading to increased sympathetic tone and perspiration.

Correct Answer: A

Rationale: Jerking movements in the face, arms, or legs can be a sign of seizures, which can occur as a result of a stroke in infants. This question is important to assess whether the infant may have experienced any seizure activity, which could indicate a potential stroke. It helps the nurse gather more information to understand the infant's symptoms and assess the possibility of a stroke event.

Correct Answer: A

Rationale: As individuals age, there is a natural increase in systolic blood pressure (the top number in a blood pressure reading). This rise is attributed to factors such as arterial stiffness, reduced compliance of blood vessels, and decreased elasticity of the arteries. This increase in systolic blood pressure with age is considered a significant risk factor for hypertension in older adults. Hypertension is commonly defined as having a systolic blood pressure of 140 mmHg or higher and/or a diastolic blood pressure of 90 mmHg or higher. Therefore, the age-related increase in systolic blood pressure contributes to the overall risk of developing hypertension in the elderly population.

Correct Answer: C

Rationale: In the case of a client diagnosed with cardiomyopathy and experiencing tachycardia, a beta blocker is the anticipated medication. Beta blockers work by blocking the effects of adrenaline on the heart, reducing heart rate, blood pressure, and myocardial oxygen demand. This can help manage symptoms of tachycardia in cardiomyopathy by slowing down the heart rate and improving its overall function. Other medications like ACE inhibitors and angiotensin II receptor blockers may be used to manage specific aspects of cardiomyopathy such as hypertension or heart failure, but in the context of tachycardia, a beta blocker is the preferred choice. Cardiac glycosides, like Digoxin, are used for heart failure but not primarily for managing tachycardia in cardiomyopathy.
