What is the rationale for the order of supplemental oxygen 10 L/min via nasal cannula? Select the best answer.

Choice A rationale:

This statement is incorrect. Antihypertensive drugs typically work by reducing blood pressure through various mechanisms, such as dilating blood vessels, reducing blood volume, or affecting the heart's workload. They do not increase blood flow to the heart and kidneys.

Choice B rationale:

This is the correct answer. Antihypertensive drugs work by affecting different aspects of the cardiovascular system, such as reducing blood vessel constriction (vasodilation), decreasing blood volume, or slowing the heart rate. By affecting these components, they can lower blood pressure.

Choice C rationale:

This statement is incorrect. Antihypertensive drugs can interact with other medications or supplements, potentially causing adverse effects or drug interactions. It's essential for the client to inform their healthcare provider of all medications and supplements they are taking to ensure safe and effective treatment.

Choice D rationale:

This statement is incorrect. Antihypertensive drugs do not cure hypertension but help control it. Clients need to understand that they will likely need to take these medications long-term to manage their blood pressure effectively.

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.
