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.

A high concentration of carbon monoxide can cause death.

B.

I should purchase a carbon monoxide detector for my home.

C.

Breathing in carbon monoxide can cause headaches and nausea.

D.

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 ["15"]

Explanation

Step 1: Determine the dosage available per mL.

  • The available dosage is 75 mg per 5 mL.
  • To find the dosage per mL, divide 75 mg by 5 mL.
  • 75 mg ÷ 5 mL = 15 mg/mL.
  • Result: 15 mg/mL.

Step 2: Determine how many mL are needed for the prescribed dose.

  • The prescribed dose is 225 mg.
  • To find the required mL, divide 225 mg by the dosage per mL (15 mg/mL).
  • 225 mg ÷ 15 mg/mL = 15 mL.
  • Result: 15 mL.

So, the nurse should administer 15 mL of clindamycin palmitate oral suspension every 8 hours.

Correct Answer is B

Explanation

Choice A Reason:

Vesicles on the skin are more commonly associated with cutaneous anthrax, not inhalation anthrax. Cutaneous anthrax typically presents with a raised, itchy bump that develops into a painless sore with a black center.

Choice B Reason:

Respiratory failure is a severe and common symptom of inhalation anthrax. Inhalation anthrax begins with flu-like symptoms but can rapidly progress to severe respiratory distress, shock, and often death if not treated promptly.

Choice C Reason:

Flu-like symptoms are indeed an early sign of inhalation anthrax, but they are not specific enough to indicate exposure definitively. These symptoms include sore throat, mild fever, fatigue, and muscle aches.

Choice D Reason:

Coughing of blood can occur in the later stages of inhalation anthrax as the disease progresses and the respiratory system becomes severely compromised.
