After the nurse gives IV atropine to a patient with symptomatic type 1. second-degree atrioventricular (AV) block, which finding indicates that the drug has been effective?
Increase in the patient's heart rate.
Decrease in premature ventricular contractions.
Increase in strength of peripheral pulses.
Decrease in premature atrial contractions
The Correct Answer is A
Atropine is an anticholinergic medication that acts by blocking the effects of the parasympathetic nervous system on the heart, leading to an increase in heart rate (positive chronotropic effect) and conduction velocity (positive dromotropic effect). In patients with symptomatic type 1 second degree atrioventricular (AV) block (also known as Mobitz type 1 or Wenckebach), the electrical impulses between the atria and ventricles are delayed or blocked intermittently, resulting in a progressive lengthening of the PR interval until a ventricular beat is dropped.
When atropine is administered to a patient with symptomatic type 1 AV block, it can counteract the increased vagal tone that contributes to the block and help improve the conduction through the AV node. As a result, the heart rate is expected to increase, which is a positive response to the medication.
The other options listed (B) Decrease in premature ventricular contractions, (C) Increase in strength of peripheral pulses, and (D) Decrease in premature atrial contractions, are not directly related to the effect of atropine on type 1 AV block and are not typical findings associated with atropine administration in this context. The main goal of administering atropine in this situation is to increase the heart rate and improve the AV conduction to alleviate symptoms associated with the AV block.

Correct Answer is D
Explanation
When a patient with dilated cardiomyopathy develops new onset atrial fibrillation (AF) that has been unresponsive to drug therapy, the nurse should prioritize patient education about anticoagulant therapy. Atrial fibrillation increases the risk of blood clots forming in the heart's atria due to the irregular and ineffective pumping of blood. These blood clots can potentially travel to other parts of the body, leading to serious complications such as stroke.
Anticoagulant therapy, also known as blood-thinning medication, is commonly prescribed for patients with atrial fibrillation to prevent the formation of blood clots. The most common anticoagulant prescribed for AF is warfarin or direct oral anticoagulants (DOACs) such as apixaban, rivaroxaban, dabigatran, or edoxaban. The nurse should educate the patient about the importance of taking the anticoagulant as prescribed and the need for regular monitoring of clotting times (INR for warfarin) to ensure the medication is effective and the dose is appropriate.
While other options listed in the choices may be relevant in specific situations, the priority in this case is to address the potential risk of stroke associated with atrial fibrillation and the importance of anticoagulant therapy to manage that risk effectively.
Correct Answer is C
Explanation
Among the given options, the most important information for the nurse to include when teaching a client newly diagnosed with hypertension is option C, "Increasing physical activity controls blood pressure (BP) for most people."
Option C emphasizes the importance of increasing physical activity as a primary lifestyle modification to control blood pressure for most people with hypertension. Regular physical activity can help improve cardiovascular health, reduce blood pressure, and manage overall health. It is a proactive step that the individual can take immediately to start managing their hypertension.
Incorrect:
Option A, "Most people are able to control BP through dietary changes," is not necessarily true for everyone. While dietary changes, such as reducing sodium intake and adopting a heart-healthy diet, can be beneficial in managing hypertension, they may not be sufficient for everyone. Physical activity is an essential component of hypertension management and has broader health benefits.
Option B, "Annual BP checks are needed to monitor treatment effectiveness," is important information, but it is more of a recommendation for ongoing hypertension management rather than the most critical information for someone newly diagnosed with hypertension. Regular blood pressure monitoring is indeed crucial for treatment assessment and ensuring that the chosen treatment plan is effective.
Option D, "Hypertension is usually asymptomatic until target organ damage occurs," is important information to understand the nature of hypertension, but it does not provide immediate guidance for the newly diagnosed individual on how to manage their condition effectively.
As part of a comprehensive hypertension education plan, the nurse can provide additional information about dietary changes, regular blood pressure monitoring, and the importance of early management to prevent target organ damage. However, emphasizing physical activity as a fundamental aspect of hypertension management is the most important initial step for a newly diagnosed client. The nurse can then tailor the education based on the individual's specific needs and health status.
