Correct Answer: B

Rationale: The correct action for the nurse to take in this situation is option B: Call the practitioner, report the client's symptoms, and obtain further orders. The client is displaying symptoms that indicate potential complications, such as internal bleeding, which require immediate medical evaluation. Option A is incorrect because the client's condition suggests a more urgent need for assessment. Option C is inappropriate as it does not address the seriousness of the client's symptoms. Option D is dangerous and could exacerbate any underlying issue the client may be experiencing.

Correct Answer: D

Rationale: When a nurse has developed a close relationship with a dying client's family, it is crucial to provide comprehensive support. Encouraging family discussion of feelings helps them express their emotions and concerns, fostering a sense of relief. Accepting the family's experience of anger without judgment validates their emotions and promotes trust. Facilitating the use of spiritual practices identified by the family acknowledges their beliefs and values, offering comfort and solace. Therefore, all of the above interventions are essential in providing holistic care and support during such a challenging time. Choices A, B, and C each play a vital role in addressing different aspects of the family's emotional and spiritual needs, making option D the correct answer.

Correct Answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

Correct Answer: D

Rationale: The correct intervention for the nurse to initiate first is to notify the client's healthcare provider of the client's stated intent to leave the hospital. This action is crucial as it ensures that the client's care and safety are appropriately managed. Option A is not the best choice as involving the family to persuade the client may not address the client's underlying concerns. Option B is incorrect because having the client sign self-discharge papers without further assessment is not appropriate. Option C is also incorrect as the client's request for treatment does not prevent them from leaving if they are deemed competent to make that decision.

Correct Answer: C

Rationale: The correct answer is 'C: Ambulance squad.' The Ambulance Squad is composed of four medical specialists and two vehicles, making it the module described in the question. Choice A, 'Patient holding squad,' is incorrect as it does not match the composition specified. Choice B, 'Surgical squad,' is incorrect as it focuses on surgical rather than general medical support. Choice D, 'Area support squad,' is incorrect as it does not align with the composition of four specialists and two vehicles.
