1. 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.

2. Upon first meeting, a new nurse manager makes eye contact, smiles, initiates conversation about the previous work experience of nurses, and encourages active participation by nurses in the dialogue. Her behavior is an example of:

A. Aggressiveness.
B. Passive aggressiveness.
C. Passiveness.
D. Assertiveness.

Correct answer: D

Rationale: The correct answer is 'Assertiveness.' This nurse manager is demonstrating assertive behavior by confidently engaging with the nurses, showing interest in their work experience, and encouraging active participation. Aggressive behavior is forceful and dominating, while passive behavior is submissive and timid. Passive-aggressive behavior involves indirect manipulation or control, which is not demonstrated in this scenario.

3. The LPN is auscultating for bowel sounds and hears between 3 and 4 bowel sounds per minute. This is a somewhat expected finding for which of these clients?

A. a 63-year-old female undergoing chemotherapy for breast cancer
B. a 56-year-old female with dementia undergoing a swallow study
C. a 34-year-old male with a PEG tube newly admitted for diabetic ketoacidosis
D. a 45-year-old male recovering from a knee replacement under general anesthesia

Correct answer: D

Rationale: When recovering from general anesthesia, hypoactive bowel sounds can be expected due to the effects of the anesthesia on gut motility. For the other clients, hearing less than 5 bowel sounds per minute would indicate an abnormal finding. In the context of the given situation, the client recovering from knee replacement surgery aligns with the expected range of bowel sounds post-general anesthesia. Therefore, choice D is the correct answer. Choices A, B, and C present scenarios where hearing less than 5 bowel sounds per minute would be abnormal, indicating potential issues that need further evaluation.

4. What is the 24-hour day-night cycle known as?

A. circadian rhythm
B. infradian rhythm
C. ultradian rhythm
D. non-REM rhythm

Correct answer: A

Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.

5. A nurse monitoring a client with a chest tube notes that there is no tidaling of fluid in the water seal chamber. After further assessment, the nurse suspects that the client's lung has reexpanded and notifies the healthcare provider. The healthcare provider verifies with the use of a chest x-ray that the lung has reexpanded, then calls the nurse to ask that the chest tube be removed. Which action should the nurse take first?

A. Explain the procedure to the client, then remove the chest tube.
B. Call the nursing supervisor.
C. Inform the healthcare provider that removal of a chest tube is not a nursing procedure.
D. Obtain petrolatum-impregnated gauze and ask another nurse to assist in removing the chest tube.

Correct answer: C

Rationale: The correct action for the nurse to take first is to inform the healthcare provider that removal of a chest tube is not a nursing procedure. Actual removal of a chest tube is the duty of a healthcare provider. If the healthcare provider insists that the nurse remove the tube, the nurse must contact the nursing supervisor. Some agencies' policies and procedures may permit an advanced practice nurse to remove a chest tube, but there is no information in the question to indicate that the nurse is an advanced practice nurse. Choice A is incorrect because the nurse should not proceed with removing the chest tube without proper authorization. Choice B is incorrect as calling the nursing supervisor should come after clarifying with the healthcare provider. Choice D is incorrect as the nurse should not begin the process of removing the chest tube without proper guidance and authorization.
