Exercise can improve circulation and cardiovascular fitness by decreasing

Correct Answer: B

Rationale: The correct answer is B because exercise can improve circulation and cardiovascular fitness by reducing the heart rate and blood pressure. When we exercise, our heart becomes more efficient at pumping blood, leading to a lower resting heart rate and reduced blood pressure. This helps improve circulation and strengthens the cardiovascular system. Explanation for why the other choices are incorrect: A: The number of small blood vessels throughout the body - Exercise actually promotes the growth of new blood vessels, improving circulation. C: High-density lipoproteins (HDL) in the blood - Exercise can increase HDL levels, which is beneficial for heart health. D: The body’s breathing capacity - Exercise can improve lung function and increase breathing capacity, but it is not directly related to circulation or cardiovascular fitness.

Correct Answer: A

Rationale: Rationale: A: Discharge planning should begin on the day of admission to ensure a smooth transition. This early start allows for comprehensive assessment and coordination of post-discharge needs. B: Waiting until after the acute crisis is resolved may lead to rushed planning and potential gaps in care. C: Discharge planning should not solely rely on the physician's discharge order as it may not address all aspects of the patient's needs. D: Patient readiness is important, but starting planning early ensures sufficient time for assessment and interventions.

Correct Answer: D

Rationale: The correct answer is D: Trendelenburg with head to the side. This position helps prevent aspiration by promoting drainage of secretions from the mouth and reducing the risk of airway obstruction. Placing the patient in Trendelenburg position with the head to the side also helps facilitate proper blood flow and ventilation. Supine with legs fully extended (A) may increase the risk of airway obstruction and aspiration. Prone with head turned to the side (B) may obstruct the airway and hinder breathing. Lateral Sims with legs flexed (C) is not suitable for a patient recovering from anesthesia as it may not provide optimal airway clearance and respiratory support.

Correct Answer: C

Rationale: The correct answer is C: Preventing spread of infection to others. This is the priority because until Mr. Jones' diagnosis is confirmed, it is crucial to prevent potential transmission of any infectious diseases to others. Encouraging rest (choice A) and providing attractive meals (choice D) are important for overall well-being but not as critical as preventing the spread of infection. Monitoring intake and output (choice B) is important for assessing Mr. Jones' health status but does not directly address the potential risk of infecting others. Therefore, choice C is the most immediate priority to ensure the safety of others.
