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.

Correct Answer: B

Rationale: The correct answer is 'a client suspected of varicella (chickenpox).' Chickenpox is an acute, infectious airborne illness that requires airborne precautions, including wearing a respirator mask for direct contact with the patient. Choices A, C, and D do not typically require airborne precautions. Choice A describes symptoms that may indicate a gastrointestinal infection but do not require airborne precautions. Choice C mentions abdominal pain and purpura, which are not specific to an airborne illness. Choice D, a client diagnosed with AIDS, does not necessitate airborne precautions unless there are additional infectious conditions present that require such measures.

Correct Answer: C

Rationale: The correct answer is, ''The distance between the slats needs to be no more than 4 inches wide to prevent entrapment of my infant's head or body.'' This statement indicates a need for further instructions as the distance between the slats should be no more than 2⅜ inches to prevent entrapment of the infant's head and body, not 4 inches. Allowing a larger gap can pose a risk of entrapment or injury to the infant. Keeping large toys out of the crib is essential to prevent the infant from using them to climb out, which could result in serious injuries. Ensuring the drop side of the crib is impossible for the infant to release is crucial to prevent falls and injuries. Additionally, maintaining wood surfaces on the crib free of splinters, cracks, and lead-based paint is vital for the infant's safety and well-being.

Correct Answer: D

Rationale: When managing nausea related to Morphine epidural analgesia, Compazine is the appropriate medication to administer. Compazine, also known as prochlorperazine, is commonly used to treat nausea and vomiting. It works by affecting certain chemicals in the brain that trigger nausea and vomiting. Choices A, B, and C are incorrect because Indomethacin, Codeine, and Ibuprofen are not typically used to manage nausea associated with Morphine epidural analgesia.

Correct Answer: A

Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.
