Correct Answer: B

Rationale: The correct answer is B: Autonomy. Autonomy in healthcare refers to respecting a patient's right to make decisions about their own care, even if those decisions may not align with healthcare providers' recommendations. In this scenario, the client's decision not to have surgery despite significant blockages in his coronary arteries demonstrates his autonomy in making choices about his own health. Choice A, Fidelity, refers to the concept of keeping promises and being faithful to commitments, which is not applicable in this situation. Choice C, Justice, involves fairness and equal treatment in healthcare, which is not the primary principle at play when a patient exercises autonomy. Choice D, Non-maleficence, relates to the principle of doing no harm, which is important but not directly relevant to the client's decision to refuse surgery.

Correct Answer: A

Rationale: The correct answer is to administer a bronchodilator. During an acute asthma attack, the priority is to open the airways and improve breathing. Bronchodilators are the first-line treatment for asthma attacks as they help dilate the bronchioles, allowing for better airflow. Monitoring oxygen saturation is important but not the priority when the patient is in distress. Placing the patient in a high Fowler's position can help with breathing but is not the initial priority. Calling for assistance can be done after initiating the appropriate treatment.

Correct Answer: A

Rationale: The correct signs of hypoglycemia are sweating and trembling. These should be managed by administering glucose to raise blood sugar levels. Headache, confusion, dizziness, fatigue, or increased heart rate are not typical signs of hypoglycemia. Administering insulin in response to hypoglycemia would further lower blood sugar levels, exacerbating the condition.

Correct Answer: B

Rationale: Phlebitis, inflammation of a vein, is a complication that requires prompt action. The most appropriate next step is to discontinue the IV infusion and notify the healthcare provider. Applying a warm compress, increasing the IV flow rate, or applying an ice pack are not appropriate interventions for phlebitis. Warm compresses may worsen inflammation, increasing the IV flow rate could exacerbate the condition, and ice packs are not recommended for phlebitis.

Correct Answer: A

Rationale: The correct answer is to instruct the older adult client to eat a light snack before bedtime. This is beneficial as it helps prevent hunger, which can disrupt sleep. Choice B is incorrect as staying in bed for a prolonged time if unable to fall asleep can lead to frustration and worsen insomnia. Choice C is incorrect as taking a 1-hour nap during the day can interfere with the ability to fall asleep at night. Choice D is incorrect as performing exercises prior to bedtime can increase alertness and make it harder to fall asleep.
