What is heart failure?

  • A. A sudden stoppage of the heart
  • B. Inability of the heart to pump blood effectively
  • C. Accumulation of excess cholesterol in the arteries
  • D. Irregular heartbeat
Correct Answer: B

Rationale: The correct answer is B: Inability of the heart to pump blood effectively. Heart failure occurs when the heart is unable to pump blood efficiently to meet the body's needs. This can lead to symptoms such as shortness of breath, fatigue, and fluid retention.

Explanation:
1. Heart failure is a chronic condition that develops over time due to various factors such as high blood pressure, heart attacks, or heart muscle damage.
2. The inability of the heart to pump blood effectively results in reduced blood flow to the body's organs and tissues.
3. This can lead to a buildup of fluid in the lungs and other parts of the body, causing symptoms like shortness of breath and swelling.
4. A sudden stoppage of the heart (Choice A) would result in cardiac arrest, not heart failure.
5. Accumulation of excess cholesterol in the arteries (Choice C) refers to atherosclerosis, not heart failure.
6. An irregular heartbeat (Choice D) may be a symptom

A client is scheduled to have a tracheostomy placed in an hour. What action by the nurse is the priority?

  • A. Administer prescribed anxiolytic medication.
  • B. Ensure that informed consent is on the chart.
  • C. Reinforce any teaching done previously.
  • D. Start the preoperative antibiotic infusion.
Correct Answer: B

Rationale: The correct answer is B: Ensure that informed consent is on the chart. This is the priority action because obtaining informed consent is essential before any procedure to ensure that the client understands the risks, benefits, and alternatives. Administering anxiolytic medication (A) may be necessary but is not the priority. Reinforcing teaching (C) and starting antibiotics (D) are important but not as urgent as ensuring informed consent.

A nurse cares for a client who has packing inserted for posterior nasal bleeding. What action would the nurse take first?

  • A. Assess the client's pain level.
  • B. Keep the client's head elevated.
  • C. Teach the client about the causes of nasal bleeding.
  • D. Assess the client's airway.
Correct Answer: D

Rationale: The correct answer is D: Assess the client's airway. This is the priority action as airway patency is always the top priority in any emergency situation. In this case, posterior nasal bleeding can lead to blood flow into the throat, potentially obstructing the airway. Ensuring the client's airway is clear and maintaining adequate oxygenation is crucial for their safety.

Choice A (Assess the client's pain level) is not the priority when there is a potential risk to the airway. Choice B (Keep the client's head elevated) may be done after confirming airway patency. Choice C (Teach the client about the causes of nasal bleeding) is important but not the immediate priority in this situation.

In the lungs

  • A. PCO2 in the alveoli is the same as that in the capillaries
  • B. PO2 in the alveoli is the same as that in the capillaries
  • C. PCO2 in the alveoli is higher than that in the capillaries
  • D. PCO2 in the alveoli is lower than that in the capillaries
Correct Answer: D

Rationale: The correct answer is D because in the lungs, during gas exchange, carbon dioxide (CO2) is removed from the blood and exhaled. This leads to a lower PCO2 in the alveoli compared to the capillaries. The concentration gradient drives the diffusion of CO2 from the capillaries to the alveoli. Options A and B are incorrect because the partial pressure of CO2 (PCO2) and oxygen (PO2) differ between the alveoli and capillaries due to gas exchange. Option C is also incorrect as PCO2 is lower in the alveoli to facilitate the removal of CO2 from the blood.

In planning care for the patient with bronchiectasis, which nursing intervention should the nurse include?

  • A. Relieve or reduce pain
  • B. Prevent paroxysmal coughing
  • C. Prevent spread of the disease to others
  • D. Promote drainage and removal of mucus
Correct Answer: D

Rationale: In planning care for the patient with bronchiectasis, the nurse should include promoting drainage and removal of mucus to prevent further complications and improve respiratory function.

As the nurse responsible for this client's care, you anticipate which physician's orders?

  • A. Endotracheal intubation and mechanical ventilation
  • B. Immediate application of CPAP to client's nose and mouth
  • C. Intravenous furosemide (Lasix) 100 mg IV push stat
  • D. Call a CODE for respiratory arrest.
Correct Answer: A

Rationale: The correct answer is A. Poor oxygenation despite non-rebreather mask suggests impending respiratory failure, necessitating intubation and mechanical ventilation. CPAP (B) and Lasix (C) may be considered but are secondary. Calling a CODE (D) is only if respiratory arrest occurs.
