The nurse is reviewing an electrocardiogram rhythm strip. The P waves and QRS complexes are regular. The PR interval is 0.16 seconds, and the QRS complexes measure 0.06 seconds. The overall heart rate is 64 beats/minute. Which would be a correct interpretation based on these characteristics?
Sinus bradycardia
Sinus arrhythmia
Sinus tachycardia
Normal sinus rhythm
The Correct Answer is D
A. Sinus bradycardia: Sinus bradycardia is characterized by a regular rhythm with a heart rate less than 60 beats per minute. In this case, the heart rate is 64 beats per minute, which falls within the normal range, not consistent with sinus bradycardia.
B. Sinus arrhythmia: Sinus arrhythmia typically presents as a variation in the R-R interval with respiration, often seen as an irregularity in the heart rate. The provided characteristics describe a regular rhythm, so sinus arrhythmia is not the correct interpretation.
C. Sinus tachycardia: Sinus tachycardia is characterized by a regular rhythm with a heart rate greater than 100 beats per minute. The heart rate in this case is 64 beats per minute, which is not indicative of sinus tachycardia.
D. Normal sinus rhythm: Normal sinus rhythm refers to a regular rhythm with a heart rate between 60 and 100 beats per minute, P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and normal QRS complex duration (less than 0.12 seconds). The provided characteristics, including regular P waves, regular QRS complexes, a PR interval of 0.16 seconds, and a heart rate of 64 beats per minute, align with a normal sinus rhythm interpretation.

Correct Answer is A
Explanation
A. Work together to see how they can incorporate healthier choices into the foods enjoyed:
This approach emphasizes collaboration between the nurse and the client, focusing on finding ways to incorporate healthier food choices into the client's diet while considering their food preferences and cultural background. By working together, the nurse can help the client identify suitable substitutions, portion control strategies, and meal planning techniques that align with the dietary recommendations for coronary heart disease. This approach promotes active participation, empowers the client to make informed decisions, and increases the likelihood of long-term adherence to the dietary plan.
B. Tell the client if they do not change their diet, they are going to have a myocardial infarction:
This approach uses fear tactics or negative consequences to motivate behavior change, which is generally not recommended in healthcare settings. Fear-based strategies may lead to increased anxiety, stress, or resistance in the client, ultimately hindering motivation and adherence to the dietary plan. Positive reinforcement, education, and collaborative goal-setting are more effective in promoting behavior change and improving adherence to lifestyle modifications.
C. Give the client a list of foods to choose from:
Providing a list of foods can be a helpful tool in guiding food choices and promoting a balanced diet. However, this approach may not address the client's individual preferences, cultural considerations, or practical challenges in implementing dietary changes. Without personalized guidance and support, the client may struggle to navigate food options effectively and may experience difficulties in adhering to the dietary recommendations.
D. It is okay to cheat because of the medications:
Encouraging cheating or deviating from the dietary plan due to medications undermines the importance of dietary modifications in managing coronary heart disease. It is essential to emphasize the significance of following a heart-healthy diet and lifestyle, as medications alone may not be sufficient to manage the condition effectively. Providing education on medication adherence and dietary guidelines, along with ongoing support, helps reinforce the importance of consistent dietary habits in promoting cardiovascular health.
Correct Answer is B
Explanation
A. Initiate a peripheral IV:
Initiating a peripheral intravenous (IV) line may be necessary for clients with unstable angina to facilitate the administration of medications and fluids, especially if there is a need for further interventions or if the client's condition deteriorates. However, in this case, the client's chest pain has improved after receiving nitroglycerin, and there is no immediate indication for IV access based on the information provided.
B. Administer another nitroglycerin tablet:
Nitroglycerin is a vasodilator commonly used to relieve chest pain (angina) by dilating blood vessels and improving blood flow to the heart. The initial response of the client's chest pain severity decreasing from 6 to 2 after one sublingual nitroglycerin tablet indicates a positive response to the medication. However, it's important to assess the client's response further before administering additional doses of nitroglycerin, especially considering the potential for hypotension or other adverse effects.
C. Call the Rapid Response Team:
The Rapid Response Team (RRT) is typically called in situations where there is a concern for a critical event or deterioration of a client's condition that requires immediate intervention. In this scenario, the client's chest pain has improved after nitroglycerin administration, and there are no indications of an acute critical event at this time. Therefore, calling the RRT is not warranted based on the client's current status.
D. Obtain an ECG:
An ECG can be helpful to assess for potential ischemia or other cardiac abnormalities. However, it's not the most urgent action when the client is responding positively to nitroglycerin. It can be done while monitoring the client's response to the second dose.
