The nurse is providing care for four patients: Patient A, diagnosed with emphysema and has an oxygen saturation of 94% on room air; Patient B, who is postoperative with a hemoglobin level of 8.2 mg/dL (82 g/L); Patient C, newly admitted with a potassium level of 3.8 mEq/L (3.8 mmol/L); and Patient D, who is scheduled for an appendectomy and has a white blood cell (WBC) count of 14,000 mm² (14 x 10°/L). What action should the nurse take next?

Choice A rationale

The patient’s history of asthma, previous hospitalizations for asthma-related symptoms, and the current presentation of difficulty breathing and wheezing suggest that she is likely experiencing an asthma exacerbation related to environmental factors. Asthma is a chronic condition that can cause symptoms such as wheezing, shortness of breath, and chest tightness, which the patient is currently experiencing. Environmental factors such as allergens, air pollution, and changes in weather can trigger asthma symptoms.

Choice B rationale

While smoking is a major risk factor for COPD, the patient denies smoking. Additionally, COPD is more common in older adults, and the patient is only 22 years old. Therefore, it is less likely that her symptoms are due to COPD.

Choice C rationale

Pneumonia is typically associated with additional symptoms such as fever, cough with phlegm, and chest pain. The patient’s symptoms do not align with a typical presentation of pneumonia.

Choice D rationale

Tuberculosis is a bacterial infection that typically presents with a chronic cough, weight loss, and night sweats. The patient’s symptoms do not align with a typical presentation of tuberculosis.

Choice D rationale

In a patient with severe ulcerative colitis who has undergone surgery for a fistula repair, replacing fluids IV based on intake and output is the most important intervention to include in the plan of care. This is because patients with ulcerative colitis often experience significant fluid and electrolyte imbalances due to diarrhea and other gastrointestinal losses. Following surgery, these imbalances can be further exacerbated by factors such as fasting, surgical stress, and the use of certain medications. Therefore, careful monitoring of fluid and electrolyte balance, and appropriate IV fluid replacement, is crucial to prevent complications such as dehydration, electrolyte imbalances, and renal dysfunction.
