Nursing Elites

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

• A. 2 liters/minute
• B. 4 liters/minute
• C. 6 liters/minute
• D. 8 liters/minute

Correct answer: C

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. What is the term for the tendency of a drug to combine with its receptor?

• A. potency
• B. efficacy
• C. kinetics
• D. affinity

Correct answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

3. When preparing a client for a neck x-ray, what is the most appropriate action for the nurse to take if the client expresses concern about removing a religious medal worn around the neck?

• A. Telling the client that the medal and chain will be kept at the nurse's station for safekeeping while the client is undergoing the x-ray
• B. Asking the client to remove the medal until the x-ray has been completed
• C. Assisting the client in pinning the medal and chain to the waistband of the client's pajama bottoms
• D. Asking the client to place the medal in the top drawer of the bedside stand just before leaving for the radiology department

Correct answer: C

Rationale: When a client undergoing a neck x-ray expresses concern about removing a religious medal worn around the neck, the nurse should assist the client in pinning the medal and chain to the hospital gown or in another area where it will not appear on the x-ray image. This action allows the client to keep the medal close without interfering with the x-ray procedure. It is important to ensure that the radiology department staff is informed about this arrangement. Asking the client to remove the medal, keeping it at the nurse's station, or placing it in the bedside stand is not appropriate. These actions may lead to the loss of the medal and chain and do not address the client's concerns about the religious significance of the item.

4. 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?

• A. A client with metastatic cancer who is receiving a continuous infusion of intravenous morphine sulfate
• B. A client with a solid-sealed cervical radiation implant
• C. A client with diarrhea for whom enteric precautions are in effect
• D. A client for whom contact precautions have been implemented and who requires frequent wound irrigations

Correct answer: B

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.

5. While caring for the following clients, a pediatric nurse tells the charge nurse she must leave due to a family emergency. Which client would the charge nurse reassign to an LPN?

• A. An eight-year-old in diabetic ketoacidosis
• B. A six-year-old in sickle cell crisis
• C. A two-month-old with dehydration
• D. A five-year-old in skeletal traction

Correct answer: D

Rationale: The correct answer is a five-year-old in skeletal traction. This task is within the scope of practice for an LPN and would need minimal assistance from an RN. The children with diabetic ketoacidosis, sickle cell crisis, and dehydration require close observation, good assessment skills, IVF needs, and medications that would be better managed by an RN. Reassigning the child in skeletal traction to an LPN ensures appropriate care while allowing the RN to focus on the more critical cases.
