A nurse is caring for a client who has a nasogastric tube. The nurse should monitor the client for which of the following findings?

The nurse should first address the client's chest pain followed by the client's irregular heart rate.

Rationale:

Chest pain is the priority concern as it indicates an acute coronary event (ST-elevation myocardial infarction, STEMI). Immediate interventions such as oxygen, nitroglycerin, and pain management are required to reduce myocardial oxygen demand and prevent further cardiac damage.

Irregular heart rate must be addressed next, as tachycardia and arrhythmias can increase myocardial workload and worsen ischemia. Monitoring and possible antiarrhythmic interventions may be required to stabilize cardiac function.

Incorrect:

Troponin levels: Elevated troponin confirms myocardial injury but does not require immediate intervention; managing the ongoing ischemia is the priority.

Oxygen saturation: The client's oxygen saturation is 93% on room air, which is adequate. Oxygen therapy is not the first priority unless levels drop further.

Hyperlipidemia: While a cardiovascular risk factor, it is not an acute concern during an MI. Long-term management is necessary but not the immediate priority.

C-reactive protein: Elevated CRP indicates inflammation but does not require urgent intervention in the acute phase of MI.

A. Constipation: Radiation therapy to the neck does not typically affect the gastrointestinal system directly. Constipation is more commonly associated with opioid pain management or radiation targeting the abdominal or pelvic region rather than the head and neck area.

B. Peripheral neuropathy: Nerve damage leading to peripheral neuropathy is more often linked to chemotherapy, particularly agents like vincristine or cisplatin, rather than radiation therapy. Radiation to the neck primarily affects tissues in the irradiated field, such as the oral mucosa.

C. Mouth ulcers: Radiation to the neck frequently causes mucositis, leading to painful mouth ulcers due to the direct impact on rapidly dividing mucosal cells. Clients may experience pain, difficulty swallowing, and increased risk of infection as a result of mucosal breakdown.

D. Decreased tear production: Radiation therapy to the neck is unlikely to directly affect the lacrimal glands. While radiation near the eyes can cause dry eyes, treatment focused on the neck primarily impacts the oral mucosa, salivary glands, and throat rather than tear production.
