A client with intestinal obstruction has a nasogastric tube to low intermittent suction and is receiving an intravenous (IV) infusion of lactated Ringer's at 100 mL/hour.
Which finding is most important for the nurse to report to the healthcare provider? Reference Range: Potassium (3.5 to 5 mEq/L (3.5 to 5 mmol/L).

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.

Choice A rationale:

The client's statement, "I should avoid foods that are high in vitamin K," indicates an understanding of the medication. Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors. Consistent intake of vitamin K-containing foods helps maintain a stable INR (International Normalized Ratio) and warfarin's effectiveness. Clients on warfarin should be educated about avoiding drastic changes in their vitamin K intake.

Choice B rationale:

Taking warfarin with food or on an empty stomach doesn't significantly impact its efficacy. Therefore, this statement is not indicative of the client's understanding of the medication.

Choice C rationale:

The statement "I should report any unusual bleeding or bruising to my provider" is important but doesn't specifically reflect an understanding of warfarin. It's a general caution for anyone taking anticoagulants.

Choice D rationale:

While it's important to avoid excessive use of medications like aspirin that can increase the risk of bleeding, this statement doesn't directly demonstrate an understanding of warfarin itself.
