A patient's data shows the following: Oxygen saturation is 94% on room air, pain is 4 on a scale of 0 to 10, temperature is 99.6°F (37.6°C) orally, and heart rate is 95 beats/minute.
Which physician orders would the nurse anticipate being prescribed after reporting these findings? Select all that apply.

Place client on oxygen 2 to 4 liters and maintain oxygen saturation at or above 95%.

Stat ventilation/perfusion (V/Q) of chest.

Stat 2 views chest x-ray.

Stat Complete blood count (CBC), basic metabolic panel (BMP), and blood cultures.

Send sputum for culture & sensitivity.

Answer and Explanation

Correct Answer : A,C,D

The correct answer is choice A, C, and D.

Choice A rationale:

The patient’s oxygen saturation is at 94%, which is just below the normal range of 95-100% for healthy adults breathing room air. Administering oxygen 2 to 4 liters to maintain oxygen saturation at or above 95% is a standard intervention to ensure adequate oxygenation.

Choice B rationale:

A stat ventilation/perfusion (V/Q) scan is typically ordered for suspected pulmonary embolism, which is not indicated by the patient’s current data. The patient’s symptoms do not specifically suggest a V/Q mismatch that would necessitate this diagnostic test.

Choice C rationale:

A chest x-ray is a common diagnostic tool for evaluating the lungs and heart, especially when a patient presents with symptoms that may indicate respiratory or cardiac issues. Given the patient’s temperature and heart rate, which are slightly elevated, a chest x-ray can help identify any potential underlying conditions.

Choice D rationale:

Ordering a CBC, BMP, and blood cultures can help identify the cause of the patient’s fever and tachycardia. These tests provide valuable information about the patient’s immune response, electrolyte balance, kidney function, and whether there is a bacterial infection.

Choice E rationale:

While sending sputum for culture and sensitivity could be helpful if a respiratory infection is suspected, the patient’s data does not strongly indicate a respiratory infection as the primary issue. Therefore, this test may not be the most immediate need.

Correct Answer is ["38"]

Explanation

Here are the steps to calculate the IV flow rate:

Step 1: Calculate the volume to be infused per minute.

75 mL ÷ 30 minutes = 2.5 mL/minute

Step 2: Multiply the volume per minute by the drop factor to determine the drops per minute.

2.5 mL/minute × 15 gtt/mL = 37.5 gtt/minute

Step 3: Round the answer to the nearest whole number. The nurse should regulate the IV to deliver 38 gtt/minute.

A. Culture for sensitive organisms. B. C-reactive protein level. C. Blood pH level. D. Serum blood glucose level.

Correct Answer is A

Explanation

Choice A rationale:

Direct identification of the causative organism: A culture for sensitive organisms is the most direct and definitive way to identify the specific bacteria or other microorganisms that are causing the infection in the wound. This information is crucial for guiding the selection of the most appropriate antibiotic therapy.

Tailored antibiotic therapy: By knowing the exact organism responsible, healthcare providers can prescribe antibiotics that are specifically effective against that organism, ensuring optimal treatment and reducing the risk of antibiotic resistance.

Informed infection control measures: The results of the culture can also inform appropriate infection control measures to prevent the spread of the infection to other patients or healthcare workers.

Monitoring treatment effectiveness: Cultures can also be used to monitor the effectiveness of antibiotic therapy. If the culture results show that the bacteria are no longer present after a course of antibiotics, this indicates that the treatment has been successful.

Choice B rationale:

Non-specific marker of inflammation: C-reactive protein (CRP) is a non-specific marker of inflammation that can be elevated in various conditions, including infections, but also in non-infectious conditions such as autoimmune diseases and trauma.

Limited diagnostic value for wound infections: While an elevated CRP level may suggest the presence of an infection, it does not provide information about the specific causative organism, which is essential for guiding antibiotic therapy.

Supplementary role: CRP levels can be used in conjunction with other clinical findings and laboratory tests to assess the severity of an infection and monitor the response to treatment, but it should not be relied upon as a sole diagnostic tool for wound infections.

Choice C rationale:

Not directly indicative of wound infection: Blood pH level primarily reflects the acid-base balance of the body and is not directly indicative of a wound infection.

Alterations in other conditions: Blood pH can be altered in various conditions, including respiratory and metabolic disorders, and is not specific to wound infections.

Limited role in diagnosis: While significant alterations in blood pH may suggest a serious systemic infection, it does not provide information about the location or causative organism of the infection.

Choice D rationale:

Not directly related to wound infection: Serum blood glucose level is primarily used to monitor diabetes and is not directly related to wound infections.

Impaired wound healing in diabetes: While elevated blood glucose levels can impair wound healing and increase the risk of infections in diabetic patients, it is not a diagnostic test for wound infections in general.

Secondary consideration: Blood glucose levels may be considered as part of the overall assessment of a patient with a wound infection, particularly in those with diabetes, but it is not a primary diagnostic tool.
