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 {"dropdown-group-1":"A","dropdown-group-2":"B","dropdown-group-3":"C"}
Explanation
The client is at risk for developing Pneumonia, Deep vein thrombosis, and Pressure ulcers
Choice A: Pneumonia
Reason: Postoperative patients, especially those who have undergone abdominal surgery, are at a higher risk of developing pneumonia. This is due to the fact that pain and discomfort can prevent them from taking deep breaths and coughing effectively, which are essential actions to clear the lungs of secretions. The nurse’s notes indicate that the client is refusing to turn and cough due to pain, which further increases the risk of pneumonia. The use of splinting with a pillow when coughing is a technique to help reduce pain and encourage effective coughing, but if the client refuses to comply, the risk remains high.
Choice B: Deep Vein Thrombosis (DVT)
Reason: Deep vein thrombosis is a significant risk for postoperative patients, particularly those who are immobile. The client in this scenario has refused to wear intermittent pneumatic compression devices, which are designed to prevent DVT by promoting blood circulation in the legs. Immobility and the lack of these devices increase the risk of blood clots forming in the deep veins of the legs. If a clot forms and travels to the lungs, it can cause a life-threatening pulmonary embolism. The nurse’s notes emphasize the importance of these devices, but the client’s refusal to use them puts them at a higher risk of developing DVT.
Choice C: Pressure Ulcers
Reason: Pressure ulcers, also known as bedsores, are a common complication for patients who are immobile for extended periods. The client’s refusal to change positions increases the risk of pressure ulcers developing on areas of the body that are in constant contact with the bed. These ulcers can be painful and lead to serious infections if not managed properly. Regular turning and repositioning are crucial in preventing pressure ulcers, and the nurse’s notes highlight the importance of this practice.
Choice D: Urinary Retention
Reason: While urinary retention can be a postoperative complication, it is less likely in this scenario because the client has a Foley catheter in place, which is draining to a bedside bag. The catheter helps to ensure that the bladder is emptied regularly, reducing the risk of urinary retention. Therefore, this is not one of the primary risks for this client based on the provided information.
Choice E: Hemorrhage
Reason: Hemorrhage, or excessive bleeding, is a potential risk after any surgery, including a total abdominal hysterectomy. However, the nurse’s notes indicate that the abdominal dressing is dry and intact, and only scant vaginal bleeding has been observed. This suggests that there is no significant bleeding at this time. While hemorrhage is always a concern, the current observations do not indicate an immediate risk.
Correct Answer is B
Explanation
Choice A reason:
Saying “Maybe next time you can have a vaginal delivery” is not supportive and may minimize the client’s current feelings of disappointment. It is important to acknowledge and validate the client’s emotions rather than focusing on future possibilities.
Choice B reason:
This response, “It sounds like you are feeling sad that things didn’t go as planned,” is empathetic and validates the client’s feelings. It shows that the nurse is listening and understands the client’s disappointment, which is crucial for emotional support.

Choice C reason:
While it is true that having a healthy baby is important, saying “At least you know you have a healthy baby” can come across as dismissive of the client’s feelings. It is essential to address the client’s emotions directly rather than shifting the focus.
Choice D reason:
Telling the client “You can resume sensations sooner than if you had delivered vaginally” is not relevant to the client’s expressed feelings of disappointment about not having a natural childbirth. This response does not address the emotional aspect of the client’s experience.
