Correct Answer: A

Rationale: During suctioning, a vagal response can be triggered leading to bradycardia. It is crucial for the nurse to monitor for this potential dysrhythmia. Tachycardia (Choice B) is less likely during suctioning and is not the priority. Premature ventricular beats (Choice C) and heart block (Choice D) can occur but are less common compared to bradycardia in this situation.

Correct Answer: B

Rationale: Lidocaine is used to treat ventricular tachycardia. This medication slowly exerts an antiarrhythmic effect by increasing the electrical stimulation threshold of the ventricles without depressing the force of ventricular contractions. It is not used for atrial arrhythmias; thus, answer A is incorrect. Answers C and D are incorrect because lidocaine does not slow the heart rate, so it is not used for heart block or bradycardia.

Correct Answer: B

Rationale: When assessing a client for signs of impending death, the nurse should observe for Cheyne-Stokes respiration. This pattern involves rhythmic waxing and waning of respirations from very deep breathing to very shallow breathing with periods of temporary apnea. It is often associated with cardiac failure and can be a significant indicator of impending death. Elevated blood pressure and pulse rate are not typical signs of impending death; in fact, they may indicate other conditions. A decreased temperature is also not a common sign of impending death, as temperature changes can vary among individuals and may not always correlate with the dying process.

Correct Answer: B

Rationale: The correct answer is 'managing symptoms of anxiety and fear.' When a client remembers childhood sexual abuse, the nurse's primary goal should be to help the client cope with the emotional distress and symptoms such as anxiety and fear. Prosecuting the perpetrator is not within the nurse's scope of practice and is a legal matter. Determining if the memories are real is not the nurse's role; the focus should be on providing support and care. Collaborating with the client's story is vague and does not address the immediate emotional needs of the client.

Correct Answer: D

Rationale: When assessing a client's self-expectations about weight loss, it is crucial to inquire about what the client considers a realistic weekly weight loss goal. This question helps in understanding the client's perception and expectations regarding the weight loss journey, enabling the establishment of achievable goals. Choices A, B, and C do not directly address the aspect of setting realistic goals for weight loss. While questioning about changing eating habits, feelings about losing weight, or the importance of weight loss are relevant, they do not specifically focus on setting achievable goals, which is essential for effective weight management.
