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: Induce Sedation
Pancuronium is not used to induce sedation. It is a neuromuscular blocking agent (NMBA) that causes paralysis of skeletal muscles. Sedation is typically achieved using medications such as benzodiazepines or propofol, which act on the central nervous system to produce a calming effect.
Choice B reason: Suppress Respiratory Effort
Pancuronium is used to suppress respiratory effort in patients with ARDS who require mechanical ventilation. By causing muscle paralysis, pancuronium helps to synchronize the patient’s breathing with the ventilator, reducing the risk of ventilator-induced lung injury and improving oxygenation. This is particularly important in severe cases of ARDS where patient-ventilator dyssynchrony can be detrimental.
Choice C reason: Decrease Chest Wall Compliance
Decreasing chest wall compliance is not a purpose of pancuronium. In fact, pancuronium does not directly affect chest wall compliance. Instead, it works by blocking the transmission of nerve impulses to the muscles, leading to muscle relaxation and paralysis.
Choice D reason: Decrease Respiratory Secretions
Pancuronium does not decrease respiratory secretions. Medications such as anticholinergics (e.g., atropine) are used to reduce secretions. Pancuronium’s primary role is to facilitate mechanical ventilation by ensuring complete muscle relaxation.
Correct Answer is A
Explanation
Choice A reason:
Check the drainage for glucose: Clear drainage from the nasal packing after a transsphenoidal hypophysectomy could indicate a cerebrospinal fluid (CSF) leak. CSF leaks are a serious complication that can occur after this type of surgery. Testing the drainage for glucose is a quick and effective way to determine if the fluid is CSF, as CSF contains glucose, whereas normal nasal secretions do not. Identifying a CSF leak promptly is crucial to prevent further complications such as meningitis.
Choice B reason:
Notify the client’s provider: While notifying the provider is important, it should be done after confirming the nature of the drainage. If the drainage is indeed CSF, the provider needs to be informed immediately. However, the initial step should be to check the drainage for glucose to confirm the suspicion.
Choice C reason:
Document the amount of drainage: Documentation is always important in nursing care, but it is not the immediate priority in this situation. The primary concern is to identify the nature of the drainage to address any potential complications promptly.
Choice D reason:
Obtain a culture of the drainage: Obtaining a culture can help identify any infections, but it is not the first step in this scenario. The immediate concern is to determine if the drainage is CSF, which requires checking for glucose.
