A nurse is teaching a client about carbon monoxide poisoning. Which of the following statements should the nurse identify as an indication that the client needs further instruction?
A high concentration of carbon monoxide can cause death.
I should purchase a carbon monoxide detector for my home.
Breathing in carbon monoxide can cause headaches and nausea.
I can detect the presence of carbon monoxide by a metallic odor.
The Correct Answer is D
Choice A reason: A High Concentration of Carbon Monoxide Can Cause Death
This statement is correct. Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be deadly at high concentrations. It binds to hemoglobin in the blood more effectively than oxygen, leading to hypoxia (lack of oxygen) in body tissues. High levels of CO can cause severe symptoms such as confusion, loss of consciousness, and death if not treated promptly.
Choice B reason: I Should Purchase a Carbon Monoxide Detector for My Home
This statement is also correct. Installing a carbon monoxide detector in the home is a crucial safety measure. These detectors can alert individuals to the presence of CO, allowing them to take action before the gas reaches dangerous levels. It is recommended to place detectors near sleeping areas and to test them regularly to ensure they are functioning properly.
Choice C reason: Breathing in Carbon Monoxide Can Cause Headaches and Nausea
This statement is accurate. Early symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, and fatigue. These symptoms occur because CO interferes with the body’s ability to transport and use oxygen, leading to hypoxia. If exposure continues, symptoms can worsen and lead to more severe health issues.
Choice D reason: I Can Detect the Presence of Carbon Monoxide by a Metallic Odor
This statement indicates a need for further instruction. Carbon monoxide is odorless, which means it cannot be detected by smell. This is why CO is often referred to as a “silent killer.” Relying on the ability to smell CO is dangerous and ineffective. The only reliable way to detect CO is through the use of a carbon monoxide detector.

Correct Answer is B
Explanation
Choice A reason:
Akathisia: Akathisia is characterized by a feeling of inner restlessness and an inability to stay still. It often manifests as constant movement, such as pacing or fidgeting. While akathisia is a common side effect of antipsychotic medications, it does not typically involve involuntary movements of the tongue and face.
Choice B reason:
Tardive dyskinesia: Tardive dyskinesia is a serious and often irreversible side effect of long-term antipsychotic use, including chlorpromazine. It is characterized by involuntary, repetitive movements, particularly of the face, tongue, and jaw. These movements can include lip smacking, tongue protrusion, and grimacing. This condition is a result of prolonged dopamine receptor blockade in the brain.
Choice C reason:
Dystonia: Dystonia involves sustained muscle contractions that cause twisting and repetitive movements or abnormal postures. It can affect any part of the body, including the neck, face, and limbs. While dystonia can be a side effect of antipsychotic medications, it typically presents as muscle spasms rather than the repetitive, involuntary movements seen in tardive dyskinesia.
Correct Answer is D
Explanation
Choice A reason:
A client with a tracheostomy tube attached to humidified oxygen is not typically at risk for hypokalemia. The primary concerns for these clients are maintaining a patent airway, preventing infection, and ensuring adequate humidification to prevent mucus plugging.
Choice B reason:
A client with an indwelling urinary catheter to gravity drainage is not specifically at risk for hypokalemia. The main risks for these clients include urinary tract infections and ensuring proper catheter care to prevent blockages.
Choice C reason:
A client with a chest tube to water seal is primarily at risk for complications related to the chest tube itself, such as infection, pneumothorax, or improper drainage. Hypokalemia is not a common risk associated with chest tubes.
Choice D reason:
A client with a nasogastric tube to suction is at risk for hypokalemia. Continuous suctioning can lead to the loss of gastric contents, which contain potassium, leading to a decrease in potassium levels in the body. This can result in hypokalemia, which needs to be monitored and managed appropriately.
