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.

Answer and Explanation

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 []

Explanation

The correct answers are:

Condition:

a. Pneumothorax
(After a thoracotomy and chest tube insertion, pneumothorax is a potential complication as air can accumulate in the pleural space, compromising lung expansion.)

Actions:

b. Administer oxygen as prescribed.
(To ensure adequate oxygenation while resolving the pneumothorax)
b. Ensure the chest tube is functioning properly.
(Ensuring the chest tube is removing air from the pleural space to restore lung expansion)

Parameters to Monitor:

c. Respiratory rate and effort.
(To assess the client's respiratory status and detect any changes indicating distress or worsening pneumothorax)
c. Oxygen saturation levels.
(To continuously assess oxygenation and detect any hypoxia)

Rationale:

A pneumothorax is more likely post-thoracotomy, especially with a chest tube insertion, as air is a primary concern in the pleural space. Monitoring respiratory parameters like oxygen saturation and respiratory effort helps evaluate the client's respiratory function and chest tube efficacy.

A. WBC count B. BUN C. Potassium

Correct Answer is A

Explanation

Choice A reason:

WBC count: An elevated white blood cell (WBC) count is a common indicator of infection. The body produces more white blood cells to fight off infections, making this a key marker for identifying infections in patients with pressure ulcers. Monitoring WBC count helps in assessing the presence and severity of an infection, guiding appropriate treatment.

Choice B reason:

BUN: Blood urea nitrogen (BUN) levels are used to assess kidney function and hydration status. Elevated BUN levels can indicate dehydration or kidney dysfunction but are not specific indicators of infection. While important for overall health assessment, BUN is not directly related to detecting infections in pressure ulcers.

Choice C reason:

Potassium: Potassium levels are crucial for maintaining normal cellular function, particularly in the heart and muscles. Abnormal potassium levels can indicate issues such as kidney dysfunction or electrolyte imbalances but do not specifically indicate infection. Monitoring potassium is important for overall health but not for diagnosing infections in pressure ulcers.
