Nokea
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.

When assessing an older patient admitted to the emergency department (ED) with a broken arm and facial bruises, the nurse observes several additional bruises in various stages of healing. Which statement or question by the nurse is most appropriate?
- A. Do you feel safe in your home?
- B. You should not return to your home.
- C. Would you like to see a social worker?
- D. I need to report my concerns to the police.
Correct Answer: A
Rationale: The correct answer is A: "Do you feel safe in your home?" This question is most appropriate because it directly addresses the potential issue of elder abuse without assuming or accusing the patient. It allows the patient to disclose any safety concerns and initiates a conversation about their well-being. Options B and D are inappropriate as they are accusatory and may escalate the situation. Option C is not as direct and may not effectively address the safety concerns of the patient.
A family member approaches the nurse caring for their gra vely ill son and states, “We want to donate our son’s organs.” What is the best action by the nu rse?
- A. Arrange a multidisciplinary meeting with physicians.
- B. Consult the hospital’s ethics committee for a ruling.
- C. Notify the organ procurement organization (OPO).
- D. Obtain family consent to withdraw life support.
Correct Answer: C
Rationale: The correct answer is C: Notify the organ procurement organization (OPO). This is the best action because the OPO is responsible for coordinating organ donation and transplantation. By involving the OPO, the nurse ensures that the donation process is handled appropriately and ethically.
Choice A: Arranging a multidisciplinary meeting with physicians may be necessary but should not be the first step in this situation.
Choice B: Consulting the hospital’s ethics committee may be helpful, but the immediate priority is to involve the OPO to facilitate organ donation.
Choice D: Obtaining family consent to withdraw life support is not the nurse’s role in this situation. The focus should be on organ donation to honor the family's wishes.
The nurse obtains a heart rate of 92 and a blood pressure of 110/76 prior to administering a scheduled dose of verapamil (Calan) for a client with atrial flutter. Which action should the nurse implement?
- A. Give intravenous (IV) calcium gluconate.
- B. Withhold the drug and notify the healthcare provider.
- C. Administer the dose as prescribed.
- D. Recheck the vital signs in 30 minutes and then administer the dose.
Correct Answer: C
Rationale: The correct answer is C: Administer the dose as prescribed. Verapamil is a calcium channel blocker used to treat atrial flutter. The vital signs obtained are within normal range for this medication. A heart rate of 92 and blood pressure of 110/76 are not contraindications for administering verapamil. Option A is incorrect as calcium gluconate is not indicated in this situation. Option B is incorrect because the vital signs are stable and do not warrant withholding the medication. Option D is incorrect as there is no need to delay the administration of verapamil based on the vital signs provided.
A male client who has been taking propranolol (Inderal) for 18 months tells the nurse that the healthcare provider discontinued the medication because his blood pressure has been normal for the past three months. Which instruction should the nurse provide?
- A. Obtain another antihypertensive prescription to avoid withdrawal symptoms.
- B. Stop the medication and keep an accurate record of blood pressure.
- C. Report any uncomfortable symptoms after stopping the medication.
- D. Ask the healthcare provider about tapering the drug dose over the next week.
Correct Answer: D
Rationale: The correct answer is D: Ask the healthcare provider about tapering the drug dose over the next week. This answer is correct because propranolol is a beta-blocker, and abrupt discontinuation can lead to rebound hypertension, angina, or even myocardial infarction due to the sudden withdrawal of the medication. Tapering the drug dose over time allows the body to adjust gradually and reduces the risk of these adverse effects.
Choice A is incorrect because obtaining another antihypertensive prescription is not necessary if the client's blood pressure has been normal for the past three months. Choice B is incorrect because abruptly stopping the medication without tapering can lead to withdrawal symptoms. Choice C is incorrect because simply reporting uncomfortable symptoms without taking appropriate action (tapering the drug dose) is not addressing the potential risks associated with abrupt discontinuation of propranolol.
Which organization requires a mechanism for addressing ethical issues?
- A. American Association of Critical-Care Nurses
- B. American Hospital Association
- C. Society of Critical Care Medicine
- D. The Joint Commission
Correct Answer: D
Rationale: The correct answer is D, The Joint Commission, because it is a regulatory body that accredits healthcare organizations and requires them to have mechanisms for addressing ethical issues to ensure patient safety and quality of care. The other choices (A, B, C) are professional organizations that focus on specific areas of healthcare practice and do not have the authority to set regulatory standards for addressing ethical issues in healthcare organizations.
