What is the purpose of performing a breast self-examination (BSE)?

Correct Answer: C

Rationale: Performing a breast self-examination (BSE) helps in identifying any changes from previous examinations. This is crucial as it allows early detection of abnormalities such as lumps, areas of thickness, or fullness that may indicate breast cancer. Monitoring changes over time helps in prompt medical intervention if needed. The other choices (A, B, D) focus on specific findings rather than the overall purpose of detecting any changes, making them incorrect.

Correct Answer: C

Rationale: The correct answer is C: Cocaine. Sinus tachycardia is a condition characterized by a fast heart rate originating from the sinus node. Cocaine is a stimulant drug that can significantly increase heart rate, exacerbating sinus tachycardia. The nurse should question the client about cocaine use to address the potential cause of the elevated heart rate. Other choices are incorrect: A: Barbiturates are central nervous system depressants and can slow heart rate, not cause sinus tachycardia. B: Opioids are also central nervous system depressants and do not typically cause sinus tachycardia. D: Benzodiazepines are sedatives and do not commonly lead to sinus tachycardia.

Correct Answer: A

Rationale: The correct answer is A because rubbing with long smooth strokes from distal to proximal parts of the extremities follows the direction of venous blood flow towards the heart, aiding venous return. This action helps prevent blood pooling in the extremities. Circular massage strokes (B) may not be as effective in promoting venous return. Rubbing with short strokes from proximal to distal parts (C) goes against the natural flow of venous blood. Smooth long strokes alternating with chopping motions (D) may not consistently promote venous blood flow in the correct direction.

Correct Answer: B

Rationale: Correct Answer: B - Avoid green leafy vegetables. Rationale: 1. Coumadin is a blood thinner that works by affecting vitamin K levels. 2. Green leafy vegetables are high in vitamin K, which can interfere with Coumadin's effectiveness. 3. Instructing the client to avoid green leafy vegetables helps maintain a consistent level of vitamin K in the diet, thus ensuring the proper effect of Coumadin. Summary of other choices: A: Having a PTT done monthly is not necessary for a client discharged with Coumadin. C: Drinking more liquids is not directly related to Coumadin therapy. D: Avoiding crowds is unrelated to Coumadin therapy and does not impact its effectiveness.

Correct Answer: B

Rationale: The correct answer is B: 15 seconds. Suction attempts should generally be limited to 15 seconds to prevent hypoxia and tissue damage. Prolonged suctioning can lead to decreased oxygenation and potential trauma to the airway. Choice A (5 seconds) may not be sufficient for effective suctioning. Choice C (30 seconds) and D (1 minute) exceed the recommended time limit and increase the risk of complications. Therefore, choice B is the most appropriate duration for a suction attempt.
