Which of the following are key parameters that produce blood pressure? (Select ONE that does not apply)
- A. Heart rate
- B. Stroke volume
- C. Peripheral resistance
- D. Neuroendocrine hormones
Correct Answer: D
Rationale: Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.

The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is experiencing shortness of breath. What is the priority nursing intervention?
- A. Administer bronchodilator therapy as prescribed
- B. Encourage deep breathing and coughing exercises
- C. Position the client in a high-Fowler's position
- D. Increase the oxygen flow rate
Correct Answer: C
Rationale: The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and ease breathing in COPD patients. While administering bronchodilator therapy as prescribed (Choice A) is important, it is not the priority in this scenario. Encouraging deep breathing and coughing exercises (Choice B) can be beneficial but do not take precedence over positioning for improved respiratory function. Increasing the oxygen flow rate (Choice D) can be considered after the initial positioning to relieve respiratory distress, making it a later intervention.
A client with chronic obstructive pulmonary disease (COPD) is receiving home oxygen therapy. What is the most important instruction the nurse should provide?
- A. Use oxygen at the highest flow rate tolerated
- B. Avoid wearing oxygen during physical activity
- C. Do not smoke while using oxygen
- D. Store oxygen tanks in a cool, dark place
Correct Answer: C
Rationale: The correct answer is C: 'Do not smoke while using oxygen.' Smoking while using oxygen can lead to a serious fire hazard, as oxygen supports combustion. This instruction is crucial to prevent potential harm to the client. Choices A, B, and D are incorrect. Using oxygen at the highest flow rate tolerated can be harmful, avoiding wearing oxygen during physical activity may limit the client's mobility unnecessarily, and storing oxygen tanks in a cool, dark place, although important, is not as critical as the instruction to avoid smoking while using oxygen.
The nurse is caring for a client who is 4 hours post-operative from abdominal surgery. The client is complaining of severe pain. What is the nurse's first action?
- A. Reassess the pain and its characteristics
- B. Administer prescribed pain medication
- C. Notify the surgeon
- D. Encourage the use of relaxation techniques
Correct Answer: A
Rationale: The correct first action for the nurse to take when a post-operative client complains of severe pain is to reassess the pain and its characteristics. Reassessment is crucial to understand the nature and intensity of the pain, which will guide the nurse in providing appropriate interventions. Administering pain medication may be necessary but should only be done after reassessment to ensure the right medication and dose are given. Notifying the surgeon may be required in certain situations, but reassessment of pain should precede this action. Encouraging relaxation techniques is not the priority when a client is experiencing severe pain post-operatively.
The client with heart failure is prescribed furosemide (Lasix). What should the nurse include in the teaching plan?
- A. Increase potassium-rich foods in the diet
- B. Avoid foods high in sodium
- C. Monitor fluid intake and adjust as needed
- D. Take the medication in the morning
Correct Answer: A
Rationale: The correct answer is to instruct the client to increase potassium-rich foods in the diet. Furosemide is a loop diuretic that can cause potassium loss as a side effect. By increasing potassium-rich foods, the client can help prevent hypokalemia, a potential complication of furosemide therapy. Choice B is incorrect because while limiting sodium intake is generally advisable for heart failure, it is not directly related to furosemide use. Choice C is incorrect because fluid intake should be monitored and adjusted based on the individual's condition, but setting a specific limit of 1 liter per day is not a standard recommendation. Choice D is incorrect because furosemide is usually taken in the morning to prevent disturbances in sleep due to increased urination during the night.
A client with a severe peanut allergy accidentally ingested peanut-containing food and is experiencing anaphylaxis. What is the nurse's priority action?
- A. Administer an epinephrine injection
- B. Call for immediate medical help
- C. Monitor airway, breathing, and circulation
- D. All of the above
Correct Answer: A
Rationale: The priority action for a client experiencing anaphylaxis due to a severe peanut allergy is to administer an epinephrine injection. Epinephrine is the first-line treatment for anaphylaxis as it can rapidly reverse the severe allergic reaction. While calling for immediate medical help is important, administering epinephrine takes precedence because it can be life-saving in this situation. Monitoring airway, breathing, and circulation is essential in managing anaphylaxis, but administering epinephrine is the priority action to halt the progression of the allergic reaction and stabilize the client's condition. Therefore, 'Administer an epinephrine injection' is the most critical initial intervention.
