Which group of foods should the nurse recommend for patients with a strong family history of colon and rectal cancers?

Choice A rationale
Applying oxygen at 10 L via non-rebreather mask and monitoring pulse oximeter is the most important intervention for a patient in the post-anesthesia care unit (PACU) with a heart rate of 140 beats/minute, blood pressure 140/90 mm Hg, and respirations 26 breaths/minute.
These vital signs suggest that the patient may be experiencing hypoxia or respiratory distress, conditions that require immediate intervention.
Choice B rationale
Medicating for pain and monitoring vital signs according to protocol is important in the PACU, but it is not the most critical intervention in this scenario. The patient’s vital signs suggest a possible respiratory issue, which should be addressed immediately.
Choice C rationale
Encouraging the client to splint the incision with a pillow to cough and deep breathe is a common postoperative intervention to promote lung expansion and prevent atelectasis and pneumonia. However, in this scenario, the patient’s vital signs suggest a more immediate respiratory issue that requires prompt intervention.
Choice D rationale
Administering an intravenous fluid bolus as prescribed by the healthcare provider can be an appropriate intervention for certain conditions in the PACU, such as hypotension. However, in this scenario, the patient’s vital signs suggest a possible respiratory issue, which should be addressed immediately.

Choice A rationale
As with, a lumbar puncture is the primary diagnostic procedure for suspected bacterial meningitis. The other choices, while useful for detecting other conditions, are not as definitive for diagnosing bacterial meningitis.
Choice B rationale
As mentioned in the rationale for, Choice B, skull radiography is not typically used to diagnose bacterial meningitis.
Choice C rationale
As mentioned in the rationale for, Choice C, an MRI can provide detailed images of the brain and surrounding tissues, but it is not the primary tool for diagnosing bacterial meningitis.
Choice D rationale
As mentioned in the rationale for, Choice D, a CT scan can detect abnormalities in the brain, but it cannot definitively diagnose bacterial meningitis.
