Correct Answer: A

Rationale: The correct intervention for a client with Raynaud's disease is to provide information about stress management. Stress management techniques can help reduce the frequency and severity of Raynaud's episodes. Choice B is incorrect because maintaining a cool temperature can exacerbate symptoms in individuals with Raynaud's disease. Choice C is incorrect as epinephrine is not typically used for Raynaud's disease. Choice D is incorrect as glucocorticoid steroids are not the first-line treatment for Raynaud's disease.

Correct Answer: C

Rationale: The correct action to maintain a sterile field is to avoid reaching over it. This prevents contamination of the sterile environment by reducing the risk of unintentionally dropping microorganisms from non-sterile areas onto the sterile field. Opening sterile packages using the flap closest to your body first (choice A) is a good practice but not directly related to maintaining the sterile field. Donning sterile gloves before opening the sterile package (choice B) is crucial for maintaining sterility but not specific to maintaining the sterile field. Placing sterile items at least 2.5 cm (1 in) from the edge of the sterile field (choice D) is important to prevent accidental contamination, but it is not the primary action to maintain the sterile field.

Correct Answer: A

Rationale: The correct answer is to verify the client's blood type with the provider's prescription. This is crucial to prevent an adverse transfusion reaction due to incompatibility. Ensuring the blood type matches before starting the transfusion is a standard safety practice. Option B, ensuring client consent, is important but not directly related to preventing a transfusion reaction. Option C, administering a diuretic, is unnecessary and can be harmful in this context. Option D, checking the client's temperature, is important for general assessment but not specifically focused on preventing a transfusion reaction.

Correct Answer: B

Rationale: The correct answer is B. The client reporting feeling less anxious is a positive indication of effective treatment for a pulmonary embolism. This suggests that the client's condition is improving psychologically. Option A is incorrect because increased density in all lung fields on a chest x-ray may indicate unresolved issues related to the embolism. Option C is incorrect as diminished breath sounds bilaterally suggest a complication or worsening of the condition. Option D is incorrect as ABG results within normal range do not necessarily indicate effective treatment for a pulmonary embolism, as other complications may still be present.

Correct Answer: C

Rationale: Taking insulin at the same time each day helps maintain stable blood glucose levels and prevent complications.
