A home health nurse is visiting a new client who uses oxygen in the home. For which factors does the nurse assess when determining if the client is using the oxygen safely? (Select all that do not apply.)

Correct Answer: D

Rationale: The correct answer is D because fluorescent light bulbs can pose a fire hazard when used near oxygen due to their high energy output. Oxygen supports combustion, and fluorescent bulbs can generate heat and sparks. A, B, and C are incorrect because they are factors that the nurse should assess for safe oxygen use in the home. Smoking prohibition prevents fire risks, functional electrical cords prevent electrical hazards, and storing flammable liquids away from oxygen reduces the risk of explosions.

Correct Answer: C

Rationale: The correct answer is C. A serum potassium level of 3.0 mEq/L after 1 week of therapy is a priority finding to communicate to the healthcare provider because digoxin, furosemide, and captopril can all cause electrolyte imbalances, especially hypokalemia, which can increase the risk of digoxin toxicity leading to life-threatening dysrhythmias. It is crucial to address and monitor potassium levels closely in patients taking these medications. A: Presence of 1+ to 2+ edema in the feet and ankles is a common finding in heart failure patients and may not be an immediate concern unless it worsens. B: Palpable liver edge 2 cm below the ribs may indicate hepatic congestion, which can occur in heart failure, but it is not as urgent as monitoring potassium levels. D: A weight increase of 2 pounds over 3 days can be a sign of fluid retention, which is important to monitor but

Correct Answer: C

Rationale: The correct answer is C: Administer prescribed antiemetics 1 hour before the treatments. This is appropriate because antiemetics are medications specifically designed to prevent or reduce nausea and vomiting. By administering antiemetics before chemotherapy, the nurse can help prevent severe vomiting in the patient. Option A is incorrect as large meals may worsen nausea. Option B may not be sufficient for severe vomiting. Option D is incorrect as citrus beverages may aggravate nausea. Administering antiemetics before chemotherapy is the most effective way to manage severe vomiting in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Targeted therapy interferes with specific molecules in cancer cells. This type of therapy is designed to target specific abnormalities or molecules that are unique to cancer cells, which helps to inhibit their growth and spread. By focusing on these specific targets, targeted therapy can be more precise and effective compared to traditional chemotherapies. A: Damaging cancer cell DNA to prevent cell replication is more characteristic of traditional chemotherapy, not targeted therapy. B: Directly killing or damaging cancerous cells is a general mechanism of action for various cancer treatments, not specific to targeted therapy. D: Preventing metastasis of cancer cells is not the primary mechanism of action of targeted therapy, which primarily focuses on inhibiting the growth and spread of cancer cells through specific molecular targeting.

Correct Answer: C

Rationale: The correct answer is C because the patient asking to learn how to clean the tracheostomy stoma shows an active interest in regaining control over personal care. This indicates a shift towards empowerment and increased sense of control. Choice A does not necessarily indicate a resolution of hopelessness as the patient allowing the nurse to suction could be due to compliance rather than empowerment. Choice B may show dependency on the spouse for care. Choice D, using a communication board to request no visitors, does not directly address regaining control over personal care.
