Correct Answer: A

Rationale: The correct initial response in CPR is to confirm unresponsiveness. This step is crucial to ensure that the person actually needs CPR before proceeding with further actions. Checking for unresponsiveness is essential to determine if the individual is in need of immediate assistance. Checking for a pulse or beginning chest compressions without confirming unresponsiveness could waste valuable time and potentially harm the individual. Calling for emergency help is important, but it should follow the confirmation of unresponsiveness to ensure timely activation of emergency services.

Correct Answer: A

Rationale: Crohn's disease is known to impair calcium absorption, which can lead to hypocalcemia. This condition affects the intestines and can disrupt the normal absorption of nutrients, including calcium. Postoperative status following appendectomy, history of bone cancer, and hyperthyroidism are typically not directly associated with a higher risk of developing hypocalcemia compared to Crohn's disease.

Correct Answer: A

Rationale: The correct answer is A: a client who has asthma. Essential oils have the potential to trigger asthma symptoms due to their strong scents and chemical components. Consulting with the healthcare provider is crucial before using aromatherapy with essential oils to ensure the safety and well-being of the client with asthma. Choices B, C, and D do not pose immediate risks with aromatherapy use, making them less of a priority for consultation compared to asthma. Clients with diabetes, hypertension, or depression do not have the same immediate risks associated with the use of aromatherapy as clients with asthma. However, it is still advisable for the nurse to be aware of any potential interactions or contraindications with these conditions and consult with the provider if needed.

Correct Answer: B

Rationale: The correct answer is B: Moist sterile non-adherent dressing. A moist sterile non-adherent dressing is suitable for covering a neural tube defect and would not require further intervention. This type of dressing helps prevent the dressing from sticking to the wound, minimizing trauma during dressing changes. Choice A, Telfa dressing with antibiotic ointment, is not ideal for a neural tube defect as the ointment may not be necessary and can complicate wound care. Choice C, dry sterile dressing that is occlusive, is not recommended for a neural tube defect as it may not provide the necessary environment for proper wound healing. Choice D, sterile occlusive pressure dressing, is excessive for a neural tube defect and may cause unnecessary pressure on the wound site.

Correct Answer: D

Rationale: The correct answer is D: 'I can take aspirin if I have a headache.' This statement indicates a need for further teaching because aspirin can increase the risk of bleeding in clients taking warfarin. Clients on warfarin therapy should avoid taking aspirin or other medications that increase the risk of bleeding. Choices A, B, and C are correct statements that show understanding of warfarin therapy, such as the importance of avoiding foods high in vitamin K, taking medication consistently, and using a soft toothbrush to prevent gum bleeding.
