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 A
Explanation
During the 48 hours after a myocardial infarction (MI), the highest priority for monitoring the patient is for dysrhythmias. After an MI, the heart's electrical system can be disrupted, leading to various types of abnormal heart rhythms (dysrhythmias). Dysrhythmias can be life-threatening and require prompt recognition and intervention.
Other options:
B) Anxiety and fear: Anxiety and fear are common emotional responses after an MI, but they are not the highest priority for monitoring during the immediate post-MI period. Emotional support and counseling are essential, but they do not require continuous monitoring.
C) Metabolic acidosis: Metabolic acidosis is not a common complication of an acute MI. It may occur in certain situations, such as when there is inadequate perfusion to tissues, but it is not the highest priority during the immediate post-MI period.
D) Medication side effects: Monitoring for medication side effects is important but is not the highest priority during the immediate post-MI period. Many patients will receive medications to manage pain, reduce clot formation, and stabilize their heart function. The nurse should monitor for side effects but not as a higher priority compared to dysrhythmias.
Correct Answer is B
Explanation
Resumption of sexual activity after a myocardial infarction (MI) is an important topic to address as part of the overall recovery and rehabilitation process. It should be discussed along with other physical activities during the patient's recovery. The nurse should initiate the discussion in a supportive and non-judgmental manner, addressing the patient's concerns, fears, and questions about sexual activity after an MI.
Sexual activity is a normal part of life, and patients may have concerns about the safety and appropriateness of engaging in sexual activity after a significant cardiac event like an MI. Discussing it along with other physical activities helps normalize the topic and allows the nurse to provide accurate information, address any misconceptions, and offer guidance on when and how to resume sexual activity safely. Patients should be encouraged to have an open dialogue with their healthcare provider about their concerns and any specific questions they may have related to resuming sexual activity.
