The nurse provides a postoperative client with an analgesic medication and darkens the room before the client goes to sleep for the night. The nurse's actions:
- A. help decrease stimuli from the cerebral cortex.
- B. stimulate hormonal changes in the brain.
- C. help the client's circadian rhythm.
- D. alert the hypothalamus in the brain.
Correct Answer: A
Rationale: The nurse's actions of providing an analgesic medication and darkening the room aim to decrease stimuli from the cerebral cortex. Reduction of environmental stimuli, especially light and noise, from the cerebral cortex, which is an area of arousal, facilitates sleep. By decreasing input to this area, the client is more likely to fall asleep and stay asleep. Choices B, C, and D are incorrect because the scenario does not involve stimulating hormonal changes, influencing the circadian rhythm, or alerting the hypothalamus.

Delegation of tasks to appropriate personnel allows the nurse to:
- A. ensure tasks are appropriately distributed.
- B. keep other members of the team productive.
- C. maintain tight control of all aspects of the workflow.
- D. recognize the importance of team members' roles.
Correct Answer: B
Rationale: Delegating tasks to appropriate personnel is essential for a nurse to keep other team members productive. By assigning tasks that align with the specific roles and responsibilities of team members, the nurse can enhance work effectiveness and efficiency. Option A is incorrect because delegation is not primarily about ensuring tasks are evenly distributed but rather about utilizing team members' skills effectively. Option C is incorrect as maintaining tight control of all aspects of the workflow can hinder teamwork and limit individual growth. Option D is incorrect because effective delegation involves empowering team members to make decisions within their scope of practice, rather than solely recognizing the importance of their roles.
Which of the following lab values is elevated first after a client has a myocardial infarction?
- A. LDH
- B. troponin
- C. CPK
- D. SGOT
Correct Answer: B
Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.
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.
In an obstetrical emergency, which of the following actions should the nurse perform first after the baby delivers?
- A. Place extra padding under the mother to absorb blood from the delivery.
- B. Cut the umbilical cord using sterile scissors.
- C. Suction the baby's mouth and nose.
- D. Wrap the baby in a clean blanket to preserve warmth.
Correct Answer: C
Rationale: In an obstetrical emergency, the immediate priority after the baby delivers is to clear the baby's airway by suctioning the mouth and nose to ensure effective breathing. This action helps prevent potential complications like meconium aspiration. Cutting the umbilical cord, wrapping the baby in a blanket, or placing extra padding under the mother can follow once the baby's airway is clear. Therefore, suctioning the baby's mouth and nose is the most critical and time-sensitive intervention in this scenario. Placing extra padding under the mother is not the immediate priority as ensuring the baby's airway is clear. Cutting the umbilical cord and wrapping the baby in a clean blanket are important but can wait until after ensuring the baby's breathing is not compromised.
Which of the following foods present a problem for a client diagnosed with Celiac Disease?
- A. butter
- B. oats or barley cereal
- C. fresh vegetables
- D. coffee or tea
Correct Answer: B
Rationale: Celiac disease, also known as celiac sprue, is a malabsorption disorder affecting the small intestine due to a problem with ingesting gluten, a protein found in wheat, rye, oats, and barley. Therefore, oats or barley cereal would present a problem for a client with Celiac Disease as they contain gluten. Fresh vegetables, butter, coffee, and tea, on the other hand, do not contain gluten and should not pose any issues for individuals with this disorder. Therefore, the correct answer is oats or barley cereal. Choices A, C, and D are not problematic for clients with Celiac Disease as they are gluten-free.
