Correct Answer: C

Rationale: The correct answer is C: “The fistula will be usable in about 4 to 6 weeks.” The rationale for this is that an arteriovenous fistula typically requires 4 to 6 weeks to mature and be ready for use. During this time, the fistula develops the necessary blood flow for efficient dialysis. Choice A is incorrect because immediate use of the fistula is not recommended as it needs time to mature. Choice B is incorrect as it underestimates the time needed for the fistula to heal and mature. Choice D is incorrect as the usability of the fistula is not dependent on the manufacturer but rather on the patient's individual healing process.

Correct Answer: D

Rationale: Rationale: The correct answer is D because the purpose of the healthcare system in the United States is primarily focused on disease prevention and symptom management. This aligns with societal views as healthcare is geared towards improving health outcomes and quality of life. Incorrect choices: A: Dying is not viewed as a failure of the system or providers, rather as a natural part of life. B: Most Americans prefer to die at home or in hospice care rather than in a hospital. C: Illnesses are not always curable, and death can result from various complex conditions beyond treatment.

Correct Answer: D

Rationale: The correct answer is D because positive end-expiratory pressure (PEEP) is a mode of ventilation where pressure is maintained in the lungs at the end of expiration. This helps prevent alveolar collapse and improves oxygenation. Option A is incorrect because PEEP does not deliver a full preset tidal volume with each breath initiation. Option B is incorrect because tidal volume in PEEP is not solely determined by the patient's ability to generate negative pressure. Option C is incorrect because in PEEP, breaths are delivered irrespective of the patient's respiratory drive.

Correct Answer: B

Rationale: The correct answer is B: Administer anticholinergic medications as prescribed. Anticholinergic medications can help dry up secretions and improve breathing in a patient nearing death. This intervention targets the underlying cause of increased secretions. Suctioning (choice A) may provide temporary relief but does not address the root issue. Elevating the head of the bed and repositioning (choice C) can help with comfort but do not directly address the secretions. Restricting oral intake (choice D) may lead to dehydration and discomfort without effectively managing the secretions. Administering anticholinergic medications is the priority as it directly targets the symptom of increased secretions, improving the patient's comfort and quality of life.

Correct Answer: C

Rationale: The correct answer is C: CCRN. The nurse works in a surgical unit, making CCRN (Critical Care Registered Nurse) the most applicable credential as it focuses on critical care nursing, which is relevant to the nurse's current practice. ACNPC (Acute Care Nurse Practitioner Certification) and PCCN (Progressive Care Certified Nurse) are not suitable as they are more focused on advanced practice or progressive care respectively, not directly related to surgical units. CCNS (Clinical Nurse Specialist Certification) is not the best choice as it is more geared towards advanced practice roles in specific clinical specialties, not general staff nursing.
