1. Which chamber of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.

2. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

3. A healthcare professional realizes that the wrong medication has been administered to a client. Which of the following actions should the healthcare professional take first?

• A. Notify the provider.
• B. Report the incident to the healthcare facility's manager.
• C. Monitor vital signs.
• D. Fill out an incident report.

Correct answer: C

Rationale: In a situation where the wrong medication has been administered to a client, the immediate priority is to assess and monitor the client's vital signs to identify any adverse effects of the incorrect medication. This action takes precedence over notifying the provider, reporting the incident, or filling out an incident report. Monitoring vital signs allows for timely recognition and intervention if the client experiences any negative reactions to the wrong medication, ensuring their safety and well-being.

4. After a walk-in client enters the clinic with a chief complaint of abdominal pain and diarrhea, the nurse takes the client’s vital signs. What phase of the nursing process is being implemented by the nurse?

• A. Assessment
• B. Diagnosis
• C. Planning
• D. Implementation

Correct answer: A

Rationale: In this scenario, the nurse is performing the assessment phase of the nursing process. Assessment involves collecting data, which includes obtaining vital signs, to identify the client's health status and needs. This step is crucial for the nurse to gather information that will guide further decision-making in the nursing process. Choice B, 'Diagnosis,' would involve analyzing the collected data to identify the client's health problems. Choice C, 'Planning,' would be developing a plan of care based on the assessment findings. Choice D, 'Implementation,' is the phase where the nurse carries out the plan of care developed during the planning phase.

5. Which of the following is not a cause of tachycardia?

• A. Fever
• B. Exercise
• C. Sympathetic nervous system stimulation
• D. Parasympathetic nervous system stimulation

Correct answer: D

Rationale: Tachycardia is an increased heart rate, and it can be caused by various factors such as fever, exercise, and sympathetic nervous system stimulation, all of which tend to increase heart rate. However, parasympathetic nervous system stimulation typically slows the heart rate, making it the exception among the choices provided. Thus, parasympathetic nervous system stimulation is not a cause of tachycardia.
