Correct Answer: B

Rationale: The correct answer is B: History of cardiac arrhythmia. Clozapine can lead to severe cardiovascular problems, making it crucial to report any history of cardiac arrhythmia to the healthcare provider before administering the medication. Choices A, C, and D are less concerning in this context as they are not directly associated with potential serious complications related to clozapine use.

Correct Answer: A

Rationale: Playing a board game with the client and initiating a conversation about stressors is the best choice to establish rapport and achieve the therapeutic goal of helping the client verbalize ways to cope with stress. Board games provide a relaxed and non-threatening environment, allowing the client to feel more comfortable and open up about their stressors. Choice B, conducting a formal therapy session, might be too structured and intimidating for the client, hindering open communication. Choice C, asking the client to write down their feelings, lacks the interactive and engaging aspect that a board game provides. Choice D, having a group discussion about stress management, may not be as effective initially as one-on-one interaction to build trust and rapport with the client.

Correct Answer: A

Rationale: The correct answer is the medication port. When adding medication to an already infusing IV solution, it should be done through the medication port to ensure direct delivery into the bloodstream without interrupting the primary IV line. Injecting the medication into the IV drip chamber, Y-site connector, or at the hub of the IV catheter can lead to dilution, inaccurate dosing, or potential blockages in the IV line, which can compromise the effectiveness of the medication and patient safety.

Correct Answer: A

Rationale: Corrected Rationale: Osteoarthritis typically involves the destruction of joint cartilage, leading to pain and stiffness. This destruction of joint cartilage results in bone rubbing against bone, causing pain and reduced mobility. Choices B, C, and D are incorrect. Inflammation of the synovial membrane (choice B) is more commonly associated with rheumatoid arthritis. Formation of bone spurs (choice C) and reduction of joint space (choice D) are manifestations that can occur as a result of osteoarthritis but are not the primary pathology responsible for the symptoms of pain and stiffness.

Correct Answer: C

Rationale: Increasing humidity in the client's room is the initial intervention for managing thick, tenacious secretions in a client with a tracheostomy. Adequate humidity helps to hydrate secretions, making them easier to clear, thus improving airway clearance. Encouraging fluid intake (Choice A) can be beneficial but is not the first-line intervention. Administering a mucolytic agent (Choice B) may be considered if increasing humidity alone is insufficient. Performing deep suctioning (Choice D) should be reserved for when other measures like increasing humidity have been ineffective.
