1. When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?

Correct answer: 6 liters/minute

Rationale: The correct answer is 6 liters/minute. When a client requires oxygen therapy, the maximum flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Nasal cannula can effectively deliver oxygen up to 6 liters/minute. Flow rates exceeding 6 liters/minute may lead to drying of the nasal passages and discomfort for the client. Higher flow rates, like 8 liters/minute, should be administered using a mask to ensure sufficient oxygenation. Options A, B, and D are incorrect as they indicate flow rates that surpass the recommended maximum for nasal cannula delivery.

2. A nurse who recently learned she is pregnant has just received client assignments for the day. Which client assignment should the nurse question as being inappropriate?

Correct answer: B: A client with a solid-sealed cervical radiation implant

Rationale: The correct answer is a client with a solid-sealed cervical radiation implant. Brachytherapy involves the implantation of a sealed radiation source within the targeted tumor tissue. A client with such an implant emits radiation as long as it is in place. Pregnant nurses should not care for clients with solid-sealed radiation implants due to the potential radiation exposure risk to the fetus. Clients under enteric precautions due to diarrhea, receiving a continuous infusion of intravenous morphine sulfate for cancer pain, or requiring contact precautions and frequent wound irrigations do not pose a risk to pregnant nurses and are appropriate assignments for them. Therefore, the nurse should question the assignment involving the client with the solid-sealed cervical radiation implant as it poses a risk to the fetus.

3. A client with which of the following conditions is at risk for developing a high ammonia level?

Correct answer: cirrhosis

Rationale: Cirrhosis is the correct answer. In cirrhosis, the liver is unable to detoxify ammonia to urea, leading to an accumulation of ammonia in the blood. This can result in hepatic encephalopathy, a condition characterized by high ammonia levels affecting brain function. Renal failure (Choice A), psoriasis (Choice B), and lupus (Choice C) are not directly associated with an increased risk of high ammonia levels as seen in cirrhosis.

4. A health care provider informs a nurse that the husband of an unconscious client with terminal cancer will not grant permission for a do-not-resuscitate (DNR) order. The health care provider tells the nurse to perform a 'slow code' and let the client 'rest in peace' if she stops breathing. How should the nurse respond?

Correct answer: Telling the health care provider that 'slow codes' are not acceptable

Rationale: The nurse may not violate a family’s request regarding the client’s treatment plan. A 'slow code' is not acceptable, and the nurse should state this to the health care provider. The definition of a 'slow code' varies among health care facilities and personnel and could be interpreted as not performing resuscitative procedures as quickly as a competent person would. Resuscitative procedures that are performed more slowly than recommended by the American Heart Association are below the standard of care and could therefore serve as the basis for a lawsuit. The other options are inappropriate: Option A is speculative and does not address the issue directly; Option B does not challenge the unethical practice of a 'slow code'; Option C is irrelevant and does not address the ethical concerns raised by the health care provider's request.

5. If a visitor accidentally knocks over a plastic pleural drainage system connected to a client, causing it to crack, what should the nurse do first?

Correct answer: C: Change the drainage system.

Rationale: When a pleural drainage system is cracked, the nurse's initial action should be to change the drainage system. This is essential to prevent potential complications like air leaks or infections. While observing the client’s response and checking for leaks are important steps, they are secondary to addressing the immediate issue of the cracked system. Notifying the physician, though necessary, can be carried out once the primary concern of the damaged system is resolved.
