What is the rationale for the order of supplemental oxygen 10 L/min via nasal cannula? Select the best answer.
To prevent hypoxia and tissue damage due to pneumonia.
To lower the blood pressure and reduce the workload of the heart.
To increase the oxygen saturation and improve the respiratory function.
To dilate the bronchioles and decrease the inflammation of the lungs.
None
None
The Correct Answer is A
Choice A rationale:
Supplemental oxygen is given to the patient to prevent hypoxia and tissue damage due to pneumonia. Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, causing cough with phlegm or pus, fever, chills, and difficulty breathing. Hypoxia occurs when the body or a region of the body is deprived of adequate oxygen supply at the tissue level. It can cause serious damage to your heart, brain, and other organs. Hence, supplemental oxygen is administered to ensure that the patient’s tissues receive adequate oxygen.
Choice B rationale:
While supplemental oxygen can indirectly help lower blood pressure by improving oxygen supply and reducing strain on the heart, it is not primarily used for this purpose. Enalapril, which the patient is already taking, is an angiotensin-converting enzyme (ACE) inhibitor that is commonly used to lower blood pressure and reduce the workload of the heart.
Choice C rationale:
Supplemental oxygen does increase the oxygen saturation and improve respiratory function. However, this is a more general rationale for providing supplemental oxygen and not specific to this patient’s condition of pneumonia.
Choice D rationale:
Supplemental oxygen does not directly dilate the bronchioles or decrease inflammation in the lungs. Medications such as bronchodilators and corticosteroids are typically used for these purposes. In this case, supplemental oxygen is being used to prevent hypoxia and tissue damage due to pneumonia.

Correct Answer is ["A","B","C"]
Explanation
Choice A rationale:
Ibuprofen 400 mg every 4 to 6 hours as needed for temperature greater than 100.5 °F (38 °C). This order is questionable because ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can potentially increase blood pressure, which could be harmful to a patient with hypertension. Furthermore, NSAIDs can mask the symptoms of infection, which could delay the diagnosis and treatment of serious infections.
Choice B rationale:
Enalapril 10 mg every morning. This order is questionable because enalapril is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension. However, ACE inhibitors can cause a dry cough, which could exacerbate the patient’s existing cough due to pneumonia. Additionally, ACE inhibitors can potentially cause hyperkalemia (high potassium levels), so it’s important to monitor the patient’s electrolyte levels.
Choice C rationale:
Supplemental oxygen 10 L/min via nasal cannula. This order is questionable because a high flow rate of oxygen can potentially cause oxygen toxicity or hyperoxia, which can lead to cellular damage. The typical flow rate for a nasal cannula is between 1-6 L/min. A flow rate of 10 L/min may be too high for this patient, especially without a specified target SpO2 range.
Choice D rationale:
Continuous pulse oximetry. This order is appropriate because it allows for continuous monitoring of the patient’s oxygen saturation levels, which is crucial in a patient with pneumonia and shortness of breath.
Choice E rationale:
Send blood for a complete blood count, electrolytes, blood cultures, and procalcitonin. This order is appropriate because these tests can help monitor the patient’s overall health status and response to treatment.
Choice F rationale:
Admit to the medical floor. This order is appropriate because the patient requires hospitalization for treatment and monitoring due to his pneumonia.
Choice G rationale:
Vital signs every 4 hours. This order is appropriate because it allows for regular monitoring of the patient’s vital signs, which can help detect any changes in his condition.
Choice H rationale:
Chest x-ray now. This order is appropriate because a chest x-ray can help confirm the diagnosis of pneumonia and assess its severity.
Choice I rationale:
Sputum culture and sensitivity. This order is appropriate because it can help identify the specific organism causing the pneumonia and determine its antibiotic sensitivity, which can guide antibiotic therapy.
Choice J rationale:
Levofloxacin 500 mg intravenously every 24 hours. This order is appropriate because levofloxacin is a broad-spectrum antibiotic commonly used to treat pneumonia.
Correct Answer is ["A","B","E"]
Explanation
Choice A rationale:
The client will have no signs of infection in the wound by day 7. Rationale: This outcome is appropriate because it sets a specific timeframe (day 7) for assessing the absence of infection in the wound. It provides a clear and measurable criterion for evaluating the effectiveness of the wound care plan.
Choice B rationale:
The client will report a pain level of 4/10 or less during dressing changes. Rationale: Pain management is an essential aspect of wound care. Setting a target pain level (4/10 or less) during dressing changes allows for monitoring and adjustment of pain management strategies, making it an appropriate outcome.
Choice C rationale:
The client will consume at least 75% of meals and snacks daily. Rationale: While nutrition is important for wound healing, this outcome is less directly related to the wound itself. Monitoring meal consumption is a valuable goal for overall health but may not be as closely tied to wound improvement as infection control, pain management, or wound care technique.
Choice D rationale:
The client will reposition self in bed every 2 hours with assistance. Rationale: Repositioning every 2 hours is an important preventive measure for pressure ulcer development. However, this choice may not be appropriate for this particular client if they are unable to reposition themselves, even with assistance. This outcome may not be achievable for all clients, and a more individualized goal may be necessary.
Choice E rationale:
The client will demonstrate proper wound care technique before discharge. Rationale: Ensuring that the client can perform proper wound care techniques independently or with minimal assistance is a crucial outcome. This ensures that the client can maintain wound hygiene and prevent complications after discharge.
