Correct Answer: B

Rationale: The correct answer is B: 'Keep oxygen equipment at least 6 feet away from heat sources.' It is crucial to keep oxygen equipment away from heat sources to prevent fire hazards. Option A is incorrect as oxygen tanks should be stored in an upright position. Option C is wrong because smoking near oxygen equipment poses a significant fire risk. Option D is also incorrect as fluid intake should not be restricted while using oxygen therapy; in fact, it is important to maintain adequate hydration.

Correct Answer: C

Rationale: Dry skin is a common manifestation of hypothyroidism due to decreased thyroid hormone levels, leading to reduced sweating and oil production. Weight gain may occur due to a slowed metabolism, not diarrhea, as hypothyroidism is more commonly associated with constipation. Hair loss is typically associated with hyperthyroidism, not hypothyroidism.

Correct Answer: D

Rationale: The correct answer is to keep the cord stump dry until it falls off. This is important to promote natural healing and prevent infection. Choice A is incorrect because cleaning the cord with hydrogen peroxide daily can actually delay healing and increase the risk of infection. Choice B is incorrect as the cord stump typically falls off within 1 to 3 weeks, not in 5 days. Choice C is incorrect because a cord stump turning black is a normal part of the healing process and does not necessarily indicate a problem requiring immediate provider contact.

Correct Answer: A

Rationale: The correct answer is to administer oxygen. In a patient experiencing respiratory distress, the primary concern is ensuring an adequate oxygen supply to the body. By administering oxygen, you can help improve oxygenation, which is crucial for the patient's overall well-being. Assessing airway patency is important but administering oxygen takes precedence as it directly addresses the oxygenation concern. Monitoring oxygen saturation is also essential, but the immediate action should be to provide oxygen. Calling for assistance can be important but is not the first priority when dealing with a patient in respiratory distress.

Correct Answer: A

Rationale: The correct action for the nurse to take after administering an influenza virus immunization by the intradermal route is to avoid massaging the site. Massaging the site can spread the vaccine, potentially reducing its effectiveness. Rubbing the site in a circular motion or applying a bandage are not recommended actions as they can also interfere with the proper absorption of the vaccine.
