A student asks the nurse why a peripherally inserted central catheter is needed for a patient receiving Total Parenteral Nutrition (TPN) with 25% dextrose. Which response by the nurse is accurate?

The required blood glucose monitoring is based on samples obtained from a central line.

There is a decreased risk for infection when 25% dextrose is infused through a central line.

The hypertonic solution will be more rapidly diluted when given through a central line.

The prescribed infusion can be given more rapidly when the patient has a central line.

Answer and Explanation

The Correct Answer is C

Choice A reason: While blood glucose monitoring is essential for patients receiving TPN, it is not specifically necessary to obtain samples from a central line. Blood glucose levels can be monitored through peripheral blood samples.

Choice B reason: There is actually an increased risk of infection with central lines compared to peripheral lines due to the invasive nature of central line placement and its location. Proper aseptic technique is critical to minimize this risk.

Choice C reason: The hypertonic solution will be more rapidly diluted when given through a central line. This is a critical point because the central veins have a higher blood flow and larger volume, which helps to quickly dilute the hypertonic TPN solution. This reduces the risk of phlebitis and damage to the smaller peripheral veins, making central lines more suitable for infusing highly concentrated solutions like 25% dextrose.

Choice D reason: While a central line can allow for the rapid administration of infusions, this is not the primary reason for its use with TPN. The key factor is the dilution of the hypertonic solution, as central lines handle high osmolarity solutions better than peripheral veins.

Correct Answer is ["A","C"]

Explanation

Choice A reason: Offering high-calorie protein snacks between meals and at bedtime is appropriate for a patient with COPD who is losing weight and eating very little. These snacks can help meet their nutritional needs and provide the extra calories and protein necessary to prevent muscle wasting and support overall health.

Choice B reason: While increasing the intake of whole grains and vegetables is generally healthy, it may not be the priority for a patient who has lost significant weight and needs to focus on higher-calorie, nutrient-dense foods. The primary goal is to address the calorie and protein deficit first.

Choice C reason: Encouraging rest before meals is beneficial as it helps conserve energy for eating. Patients with COPD often experience fatigue, which can reduce their appetite and ability to eat. Resting before meals can help them feel more energetic and better able to consume their meals.

Choice D reason: Providing a large glass of juice with each meal is not ideal for increasing calorie and protein intake. While juice can provide some calories and nutrients, it is not a good source of protein. Additionally, large volumes of liquid can create a feeling of fullness, reducing the patient's appetite for nutrient-dense foods.

A. Administer antibiotics B. Start IV fluids C. Assess pain every 4 hours D. Maintain oxygenation

Correct Answer is D

Explanation

Choice A reason: Administering antibiotics is essential for treating cellulitis to eliminate the infection. However, it is not the immediate priority over maintaining oxygenation, especially in a patient with sickle cell disease.

Choice B reason: Starting IV fluids is crucial for preventing dehydration and helping to reduce the sickling of red blood cells. Nevertheless, while important, it is not the most urgent action compared to maintaining adequate oxygen levels.

Choice C reason: Assessing pain every 4 hours is necessary for managing the patient's comfort and monitoring the progression of the disease. Although pain management is a significant aspect of care, it is not the top priority in this scenario.

Choice D reason: Maintaining oxygenation is the highest priority for a patient with sickle cell disease. These patients are at increased risk for hypoxia, which can exacerbate the sickling of red blood cells, leading to severe complications such as acute chest syndrome or stroke. Ensuring adequate oxygenation helps to prevent these complications and stabilizes the patient's condition.
