A patient’s vital signs are pulse 87, respirations 24, BP of 128/64 mm Hg, and cardiac output is 4.7 L/min. The patient’s stroke volume is ______ mL. (Round to the nearest whole number.)
- A. 54
- B. 64
- C. 74
- D. 84
Correct Answer: A
Rationale: The stroke volume is calculated by dividing the cardiac output by the heart rate. Given the cardiac output of 4.7 L/min and a heart rate of 87 bpm, the stroke volume is 54 mL (4700 mL/87 bpm ≈ 54 mL). Therefore, choice A (54) is the correct answer. Choices B, C, and D are incorrect as they do not match the calculated stroke volume based on the provided cardiac output and heart rate.

Which patient should the nurse refer for hospice care?
- A. A 60-year-old with lymphoma whose children are unable to discuss issues related to dying.
- B. A 72-year-old with chronic severe pain due to spinal arthritis and vertebral collapse.
- C. A 28-year-old with AIDS-related dementia who needs palliative care and pain management.
- D. A 56-year-old with advanced liver failure whose family members can no longer provide care in the home.
Correct Answer: C
Rationale: The correct answer is C because the patient with AIDS-related dementia requires palliative care and pain management, which are key components of hospice care. This patient is likely in the terminal stage of their illness and would benefit from the comprehensive support provided by hospice services.
Choice A is incorrect because the patient's children's inability to discuss dying issues does not necessarily indicate a need for hospice care. Choice B is incorrect as chronic severe pain due to spinal arthritis is not a sole criterion for hospice referral. Choice D is incorrect as advanced liver failure alone does not automatically qualify a patient for hospice care.
A nurse wishes to practice using the Synergy Model developed by the American Association of Critical-Care Nurses (AACN). What nursing behavior best supports use of this model?
- A. Attending mandatory hospital-wide in-service programs
- B. Self-directed study of best practice for the patients she cares for
- C. Gathering demographic data on the patients admitted to the unit
- D. Participating in a research study as a data collector
Correct Answer: B
Rationale: The correct answer is B: Self-directed study of best practice for the patients she cares for. This choice aligns with the Synergy Model by promoting individualized patient care based on best practices. Self-directed study allows the nurse to enhance their knowledge and skills to provide optimal care tailored to each patient's unique needs. Attending mandatory in-service programs (A) may not directly support the individualized care approach. Gathering demographic data (C) is important but not specific to the Synergy Model's focus on patient acuity and nurse competencies. Participating in a research study (D) may contribute to evidence-based practice, but it does not directly relate to the Synergy Model's emphasis on aligning nurse competencies with patient needs.
While family members are visiting, a patient has a respiratory arrest and is being resuscitated. Which action by the nurse is best?
- A. Ask family members if they wish to remain in the room during the resuscitation.
- B. Take the family members quickly out of the patient's room and remain with them.
- C. Assign a staff member to wait with family members just outside the patient's room.
- D. Encourage family members to stay, but advise them on the potential stress of the situation.
Correct Answer: A
Rationale: The correct answer is A because it respects the patient's right to privacy while also acknowledging the family's presence. By asking family members if they wish to remain in the room, the nurse allows them to make an informed decision based on their comfort level. This approach fosters open communication and shows respect for the family's emotions.
Choice B is incorrect because abruptly removing family members can increase their distress and feelings of powerlessness. Choice C is incorrect as it places the burden of support solely on a staff member, potentially isolating the family from the situation. Choice D is incorrect as it assumes family members should stay without considering their preferences or emotional well-being.
Family members are in the patient’s room when the patient has a cardiac arrest and the staff starts resuscitation measures. Which action should the nurse take next?
- A. Keep the family in the room and assign a staff member to explain the care given and answer questions.
- B. Ask the family to wait outside the patient’s room with a designated staff member to provide emotional support.
- C. Ask the family members whether they would prefer to remain in the patient’s room or wait outside the room.
- D. Tell the family members that patients are comforted by having family members present during resuscitation efforts.
Correct Answer: C
Rationale: The correct answer is C because it involves patient-centered care and respects the family's preferences. By asking the family members whether they would prefer to remain in the patient's room or wait outside, the nurse acknowledges their needs and allows them to make an informed decision based on their comfort level. This empowers the family members and promotes a supportive environment during a stressful situation.
Choice A is incorrect because it assumes that keeping the family in the room without their input is the best approach, which may not be the case for all families. Choice B is incorrect because asking the family to wait outside without considering their preferences may not be the most supportive action. Choice D is incorrect because it makes a blanket statement about patient comfort without considering individual family dynamics and preferences.
The nurse discharging a patient diagnosed with asthma ins tructs the patient to prevent exacerbation by taking what action?
- A. Obtaining an appointment for follow-up pulmonary fuanbcirtbi.oconm s/tteusdt ies 1 week after discharge.
- B. Limiting activity until patient is able to climb two flights of stairs.
- C. Taking all asthma medications as prescribed.
- D. Taking medications on a “prn” basis according to symapbtiorbm.cosm. /test
Correct Answer: C
Rationale: The correct answer is C: Taking all asthma medications as prescribed. This is the most appropriate action to prevent exacerbation of asthma symptoms. By taking medications as prescribed, the patient can effectively manage and control their asthma, reducing the risk of exacerbation. Following the prescribed medication regimen helps to keep inflammation in check and maintain airway function.
Choice A is incorrect because while follow-up appointments are important, they do not directly prevent exacerbation. Choice B is incorrect as limiting activity may not address the underlying cause of exacerbation. Choice D is incorrect as taking medications on an "as needed" basis may not provide consistent control of asthma symptoms, leading to potential exacerbation.
