A nurse on a telemetry unit is assessing a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min and the PR interval is 0.24 seconds. The nurse should interpret this finding as which of the following cardiac rhythms?
Atrial fibrillation
First-degree AV block
Premature ventricular contraction
Sinus bradycardia
The Correct Answer is B
The correct answer is B.
Choice A reason: Atrial fibrillation is characterized by a rapid, irregular heartbeat and an absence of distinct P waves on the ECG, which is not indicated by the information provided.
Choice B reason: First-degree AV block is indicated by a prolonged PR interval without affecting the overall heart rate, aligning with the client’s PR interval of 0.24 seconds.
Choice C reason: Premature ventricular contraction would show an abnormal QRS complex on the ECG, which is not mentioned in the scenario.
Choice D reason: Sinus bradycardia is defined by a heart rate less than 60 bpm, which does not apply here as the client’s heart rate is 69/min, within the normal range of 60-100 bpm.

B- "I will leave my baby's bib on while he is sleeping." This statement indicates a lack of understanding. It is not safe to leave a bib on an infant while they are sleeping as it can pose a suffocation risk.
C- "I will leave the plastic covering on the crib mattress." This statement indicates a lack of understanding. The plastic covering on the crib mattress should be removed as it can pose a suffocation hazard.
D- "I will lay my baby's head on a pillow while he is in the crib." This statement indicates a lack of understanding. Pillows should not be used in the crib for infants as they can increase the risk of suffocation and SIDS (Sudden Infant Death Syndrome).
Correct Answer is B
Explanation
Choice A reason:
Substitute tobacco use with an electronic cigarette Electronic cigarette, also known as e-cigarettes or vapes, are not recommended as a primary treatment for nicotine withdrawal. While they may be considered less harmful than traditional tobacco products, their long-term safety and effectiveness in helping individuals quit smoking are still a subject of debate and research. It is generally better to opt for proven nicotine replacement therapies, such as nicotine gum, patches, lozenges, or other medications approved by healthcare providers for smoking cessation.
Choice B reason:
Limitin use of nicotine gum to 6 months is the correct choice. When discussing treatment options with a client experiencing nicotine withdrawal, the nurse should include the information that the use of nicotine gum should be limited to 6 months. Nicotine gum is a form of nicotine replacement therapy (NRT) used to help individuals quit smoking by reducing withdrawal symptoms and cravings.
However, prolonged use of nicotine gum can lead to its own dependence on nicotine, which is counterproductive to the goal of quitting smoking altogether. The use of NRT is typically recommended for a limited duration, and the goal is to gradually reduce the dosage over time until the individual can comfortably quit nicotine use altogether.
Choice C reason:
Using progressively larger nicotine patches Using progressively larger nicotine patches is not a recommended approach for nicotine withdrawal. Nicotine patches are available in different strengths, and the appropriate dosage should be determined based on the individual's smoking history and nicotine dependence. Starting with the appropriate strength and gradually reducing the dosage over time is the preferred approach to help clients quit smoking.
Choice D reason:
Using up to 40 nicotine lozenges per day the use of nicotine lozenges should be guided by the instructions provided with the product or as prescribed by a healthcare provider. It is not advisable to exceed the recommended dosage. Using excessive amounts of nicotine lozenges or any other NRT product can lead to nicotine toxicity and other adverse effects.
