Critical Care Nursing NCLEX Questions

Correct Answer: B

Rationale: The correct answer is B: �This injection is being given to prevent blood clots from forming.� Enoxaparin is an anticoagulant used to prevent blood clots. It is administered through injection, not orally (A). Enoxaparin does not dissolve existing blood clots (C). Contacting the primary care provider to discuss the medication is not necessary in this scenario (D). The correct choice emphasizes the purpose of enoxaparin in preventing new blood clots.

Correct Answer: A

Rationale: Step 1: Checking circulation to the right hand is crucial for assessing perfusion and detecting potential complications. Step 2: Arterial line placement can compromise blood flow, leading to ischemia if circulation is impaired. Step 3: Monitoring circulation every 2 hours allows for early detection of issues and prompt intervention. Step 4: This action ensures patient safety and prevents complications. Summary: - Choice B is incorrect as pressurized flush solution can increase the risk of complications. - Choice C is incorrect as monitoring the waveform is important but not the most critical action. - Choice D is incorrect as limb restraints can impede circulation and are unnecessary in this scenario.

Correct Answer: A

Rationale: Step 1: Asking if these wishes have been discussed with the healthcare provider is important to ensure that the patient's wishes are documented and considered in the care plan. Step 2: The healthcare provider needs to be aware of the patient's preferences regarding resuscitation to provide appropriate care. Step 3: This step helps in clarifying the patient's preferences and ensures that the healthcare team follows the patient's wishes. Step 4: Placing a DNR notation without consulting the healthcare provider may not align with the patient's overall care plan and may lead to potential legal and ethical issues. Step 5: Informing the patient about notarized advance directives and designating a person for healthcare decisions are important but not the immediate step needed in this scenario. In summary, choice A is correct as it prioritizes communication with the healthcare provider to ensure the patient's wishes are properly documented and followed. Choices B, C, and D are incorrect because they do not involve confirming the patient's wishes

Correct Answer: C

Rationale: The correct answer is C because placing the patient with the head of the bed elevated 30 degrees is the best position for obtaining an accurate PAOP reading. Elevating the head of the bed helps to align the phlebostatic axis with the atrium, ensuring an accurate measurement of PAOP. This position reduces the impact of hydrostatic pressure on the reading. Options A and D are incorrect because the supine position and recording during exhalation or just before the increase in pressures during inhalation can lead to inaccurate readings. Option B is incorrect because documenting the average PAOP after three measurements does not address the importance of positioning for accuracy.

Correct Answer: B

Rationale: The correct answer is B: Administer oxygen as prescribed. Dyspnea in a hospice patient often indicates respiratory distress, and administering oxygen can help improve oxygenation and alleviate breathing difficulty. Positioning the patient flat on their back (A) may worsen dyspnea due to increased pressure on the diaphragm. Restricting fluid intake (C) is not appropriate as dehydration can exacerbate respiratory distress. Chest physiotherapy (D) may not be suitable for a hospice patient experiencing dyspnea as it can be physically taxing and may not address the underlying cause effectively.
