In assessing a patient, the nurse understands that what sym ptomology is an early sign of hypoxemia?
- A. Clubbing of nail beds
- B. Cyanosis
- C. Hypotension
- D. Restlessness
Correct Answer: D
Rationale: Step 1: Restlessness is an early sign of hypoxemia due to the body's response to low oxygen levels.
Step 2: Restlessness occurs as the body tries to increase oxygen intake.
Step 3: Other choices are incorrect because clubbing and cyanosis are late signs, while hypotension is not a specific early sign of hypoxemia.

The family members of a critically ill, 90-year-old patient bring in a copy of the patient’s living will to the hospital, which identifies the patient’s wiasbhireb.sc orme/gteasrt ding health care. The nurse discusses the contents of the living will with the patient’s physician. This is an example of implementation of which of the AACN Standards of Pr ofessional Performance?
- A. Acquires and maintains current knowledge of practice
- B. Acts ethically on the behalf of the patient and family
- C. Considers factors related to safe patient care
- D. Uses clinical inquiry and integrates research findings i n practice
Correct Answer: C
Rationale: The correct answer is C: Considers factors related to safe patient care. The scenario involves the nurse discussing the patient's living will with the physician, which is essential for ensuring safe patient care by following the patient's preferences. This aligns with the AACN standard of considering factors related to safe patient care, as the nurse is actively involving all relevant parties in decision-making to provide care that is in line with the patient's wishes.
Explanation of why other choices are incorrect:
A: Acquires and maintains current knowledge of practice - While important, this choice does not directly relate to the scenario where the focus is on safe patient care through communication and collaboration.
B: Acts ethically on behalf of the patient and family - While ethics are important, the scenario is more about following the patient's wishes as outlined in the living will rather than making ethical decisions.
D: Uses clinical inquiry and integrates research findings in practice - While valuable in nursing practice, this choice does not directly apply to the scenario where
The nurse uses subtle measures of painful stimuli, such as nailbed pressure to elicit a response from a neurologically impaired patient. By using this meth od rather than nipple pinching, the nurse is exemplifying what ethical principle?
- A. Beneficence
- B. Fidelity
- C. Nonmaleficence
- D. Veracity
Correct Answer: C
Rationale: The correct answer is C: Nonmaleficence. The nurse is demonstrating nonmaleficence by choosing a less harmful method (nailbed pressure) to assess pain in a neurologically impaired patient, instead of a more painful method (nipple pinching). Nonmaleficence is the ethical principle of avoiding harm or minimizing harm to the patient. In this scenario, the nurse is prioritizing the well-being and comfort of the patient by using a less invasive and painful method to elicit a response. Choices A, B, and D are incorrect because beneficence refers to doing good for the patient, fidelity to being loyal and maintaining trust, and veracity to truthfulness and honesty, none of which directly apply in this situation.
The nurse is caring for four patients on the progressive car e unit. Which patient is at greatest risk for developing delirium?
- A. 36-year-old recovering from a motor vehicle crash with an alcohol withdrawal protocol.
- B. 54-year-old postoperative aortic aneurysm resection with an elevated creatinine level
- C. 86-year-old from nursing home, postoperative from coalboirnb .croemse/tecstti on
- D. 95-year-old with community-acquired pneumonia; fam ily has brought in eyeglasses and hearing aid
Correct Answer: C
Rationale: The correct answer is C, the 86-year-old postoperative from colonic resection. This patient is at the greatest risk for delirium due to being elderly, having undergone surgery, and having a history of being from a nursing home. These factors contribute to an increased susceptibility to delirium.
A: The 36-year-old with alcohol withdrawal may be at risk for delirium tremens, but the older age of the patient in choice C places them at higher risk.
B: The 54-year-old with an elevated creatinine level postoperative is at risk for complications, but age and history of nursing home placement increase the risk for delirium in choice C.
D: The 95-year-old with community-acquired pneumonia is at risk for delirium, but the combination of age, surgery, and nursing home history in choice C presents a greater risk.
The nurse is preparing to obtain a pulmonary artery occlusion pressure (PAOP) reading for a patient who is mechanically ventilated. Ensuring that the aaibri-rbf.lcuoimd/ teinstt erface is at the level of the phlebostatic axis, what is the best nursing action?
- A. Place the patient in the supine position and record the PAOP immediately after exhalation.
- B. Place the patient in the supine position and document the average PAOP obtained after three measurements.
- C. Place the patient with the head of bed elevated 30 degrees and document the average PAOP pressure obtained.
- D. Place the patient with the head of bed elevated 30 degr ees and record the PAOP just before the increase in pressures during inhalation.
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.
What are the diagnostic criteria for acute respiratory distress syndrome (ARDS)? (Select all that apply.)
- A. Bilateral infiltrates on chest x-ray study
- B. Decreased cardiac output
- C. PaO /FiO ratio of less than 200 2 2
- D. Pulmonary artery occlusion pressure (PAOP) of more than 18 mm Hg
Correct Answer: A
Rationale: The correct answer is A: Bilateral infiltrates on chest x-ray study. ARDS diagnosis requires bilateral infiltrates on chest x-ray, indicative of non-cardiogenic pulmonary edema. Choice B, decreased cardiac output, is not a diagnostic criterion for ARDS. Choice C, PaO2/FiO2 ratio of less than 200, is a key diagnostic criteria for ARDS, indicating severe hypoxemia. Choice D, PAOP of more than 18 mm Hg, is used to differentiate between cardiogenic and non-cardiogenic causes of pulmonary edema, but it is not a direct diagnostic criterion for ARDS.
