Nursing Elites

1. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?

• A. serotonin
• B. cortisol
• C. alcohol
• D. narcotics

Correct answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.

2. A 51-year-old client with amyotrophic lateral sclerosis (Lou Gehrig disease) is admitted to the hospital because his condition is deteriorating. The client tells the nurse that he wants a do-not-resuscitate (DNR) order. The nurse should provide the client with which information?

• A. Oral consent is not sufficient, and the client's request will be honored by all healthcare providers.
• B. Consent must be obtained from the family.
• C. The DNR request should be discussed with the healthcare provider, who will write the order.
• D. The healthcare provider makes the final decision about a DNR request.

Correct answer: C

Rationale: When a client requests a DNR order, the nurse should contact the healthcare provider so that the provider may discuss the request with the client. A DNR order should be written, not verbal, following agency and state guidelines. Therefore, the correct answer is that the DNR request should be discussed with the healthcare provider, who will write the order. Option A is incorrect as oral consent is not sufficient for a DNR order. Option B is incorrect because the client, not the family, has the authority to request a DNR order. Option D is incorrect because the healthcare provider discusses the request with the client but does not make the final decision.

3. During surgery, it is found that a client with adenocarcinoma of the rectum has positive peritoneal lymph nodes. What is the next most likely site of metastasis?

• A. brain
• B. bone
• C. liver
• D. mediastinum

Correct answer: C

Rationale: In cases of adenocarcinoma of the rectum with positive peritoneal lymph nodes, the most likely site of metastasis is the liver. Colon tumors commonly spread through the lymphatics and portal vein to the liver. While metastasis to the brain, bone, or mediastinum is possible, the liver is typically the first to be affected due to the anatomical pathways involved in colorectal cancer metastasis. Therefore, the correct answer is the liver. Metastasis to the brain, bone, or mediastinum would be less likely at this stage of colorectal cancer progression.

4. An LPN is talking with a client scheduled to undergo a vasectomy in the next few minutes. He states, "I know I signed the form and all, but I'm not feeling so sure of this. It can be reversed pretty easily, right?"? What is the LPN's best response?

• A. "Yes, vasectomies can be reversed, but once you have it, you may regret it later."?
• B. "It's normal to feel a little nervous before a procedure like this."?
• C. "It sounds like you have a few more questions you'd like answered. Let me grab the doctor quickly so he can answer them for you."?
• D. "It sounds like you might be a little nervous. Don't worry, this is a pretty minor procedure, and the doctor doing it is the best we have. You're in great hands."?

Correct answer: C

Rationale: The best response for the LPN is to acknowledge the client's concerns and offer to provide more information. By offering to get the doctor to answer any additional questions, the LPN shows respect for the client's right to informed consent. Option A provides some information but dismisses the client's uncertainty and implies they won't regret the decision, which may not be the case. Option B acknowledges nervousness but doesn't directly address the client's request for more information. Option D attempts to reassure the client but fails to address the need for additional questions to be answered by the doctor.

5. The mother of a child who weighs 45 lb asks a nurse about car safety seats. The nurse tells the mother to place the child in which car safety seat?

• A. Car safety seat in the back seat in a face-forward position
• B. Booster seat with one of the car's seat belts placed over the child
• C. Booster seat in a rear-facing position in the front seat
• D. Car safety seat in a face-forward position in the front seat

Correct answer: B

Rationale: The correct answer is to place the child in a booster seat with one of the car's seat belts placed over the child. A child needs to remain in a car safety seat until he or she weighs 40 lb. Once the child has outgrown the car safety seat, a booster seat is used. Booster seats are designed to raise the child high enough so that the restraining straps are correctly positioned over the child's chest and pelvis, providing optimal safety. Placing a child in a booster seat in a rear-facing position in the front seat is incorrect as children should not be seated in the front seat due to potential airbag-related injuries. Additionally, car safety seats are used for children weighing less than 40 lb and are placed in the middle of the back seat in a rear-facing position for maximum protection.
