The client with Clostridium difficile in the stool receives a prescription for vancomycin PO. Which action should the nurse take before administering the first dose?

Choice A rationale:

Deep breathing and coughing exercises are not a priority intervention immediately following eye surgery. They are more commonly used to prevent postoperative pulmonary complications, such as pneumonia or atelectasis, in patients who have undergone general anesthesia or have respiratory conditions.

While deep breathing and coughing exercises can help promote circulation and prevent blood clots, they are not directly relevant to protecting the eye after surgery.

Engaging in deep breathing and coughing exercises too soon after eye surgery could potentially increase intraocular pressure, which could strain the healing eye and potentially lead to complications.

Choice B rationale:

Obtaining vital signs every 2 hours is a standard nursing intervention for monitoring a patient's overall condition, but it is not the most immediate priority following eye surgery.

Vital signs can provide important information about the patient's heart rate, blood pressure, respiratory rate, and temperature, but they do not directly address the protection of the surgically treated eye.

While monitoring vital signs is important, it does not specifically address the prevention of injury or complications to the eye itself.

Choice C rationale:

Providing an eye shield is the most crucial intervention to protect the eye immediately following surgery. The eye shield serves several important purposes:

Protection from accidental injury: It prevents the patient from accidentally rubbing or bumping the eye during sleep, which could cause further damage or disrupt the healing process.

Prevention of infection: It helps to keep the eye clean and free from debris, reducing the risk of infection. Reduction of swelling: It can help to minimize swelling and discomfort by applying gentle pressure to the eye area.

Promotion of healing: By creating a dark and protected environment, the eye shield can promote rest and healing of the tissues.

Choice D rationale:

Teaching a family member to administer eye drops is an important intervention for long-term care, but it is not the most immediate priority following surgery.

The patient may be able to administer eye drops independently, or a nurse may be responsible for administering them in the initial post-operative period.

Focusing on teaching family members about eye drop administration right after surgery could distract from more urgent priorities, such as protecting the eye with an eye shield.

Choice A rationale:

Hemoglobin A1C (HbA1C) is a blood test that reflects a person's average blood glucose levels over the past 2-3 months. It's considered the gold standard for diagnosing and monitoring diabetes.

An HbA1C level of 8.29% is significantly elevated above the reference range of 4-5.99%, indicating a high probability of diabetes.

The patient's HbA1C has also increased from 7.59% three months ago, suggesting a worsening of glycemic control.

Diabetes mellitus is a chronic metabolic disorder characterized by elevated blood glucose levels due to impaired insulin production or action, or both.

Common symptoms of diabetes include increased thirst, frequent urination, fatigue, blurred vision, and slow-healing wounds.

Early diagnosis and treatment of diabetes are crucial to prevent complications such as heart disease, stroke, kidney disease, nerve damage, and vision loss.

Choice B rationale:

Hypoglycemia refers to abnormally low blood glucose levels, typically below 70 mg/dL. It's often caused by excessive insulin or medication, missed meals, or strenuous exercise.

The patient's HbA1C level of 8.29% does not support a diagnosis of hypoglycemia.

Choice C rationale:

Hyperglycemia refers to abnormally high blood glucose levels, typically above 180 mg/dL. It can be caused by diabetes, stress, infection, or certain medications.

While the patient's HbA1C level does indicate hyperglycemia, it's specifically the pattern of elevated HbA1C over time that points to a diagnosis of diabetes mellitus, rather than transient hyperglycemia.

Choice D rationale:

Prediabetes is a condition where blood glucose levels are higher than normal, but not high enough to be classified as diabetes. People with prediabetes are at increased risk of developing diabetes.

The patient's HbA1C level of 8.29% is above the threshold for prediabetes, which is typically 5.7-6.4%.
