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 ["B","C","D"]

Explanation

Choice A reason: Anorexia, nausea, and vomiting are not typical findings associated with Cushing syndrome. These symptoms can be related to other medical conditions but do not specifically indicate Cushing syndrome.

Choice B reason: Truncal obesity, thin extremities, and rounding of the face (moon face) are classic signs of Cushing syndrome. This condition leads to fat redistribution, resulting in increased fat around the trunk and face while the extremities appear thinner. The distinctive appearance of moon face is due to fat accumulation.

Choice C reason: Purplish streaks on the abdomen, also known as striae, are a common feature of Cushing syndrome. These stretch marks occur due to the excessive production of cortisol, which weakens the connective tissue, leading to skin changes.

Choice D reason: Hyperglycemia, or high blood sugar, is frequently seen in patients with Cushing syndrome. The excess cortisol increases glucose production and decreases insulin sensitivity, leading to elevated blood sugar levels.

Choice E reason: A bronzed appearance of the skin is not a typical finding of Cushing syndrome. This symptom is more commonly associated with Addison's disease, which involves adrenal insufficiency rather than excess cortisol production seen in Cushing syndrome.

A. Hypotension, chills, thirst B. Lethargy, confusion, bradycardia C. Bradycardia, hypotension, low urine output D. Fever, tachycardia, tremors

Correct Answer is D

Explanation

Choice A reason: Hypotension, chills, and thirst are not characteristic signs and symptoms of a thyroid storm. Hypotension generally indicates low blood pressure, while chills and thirst are less specific symptoms that do not particularly point to thyroid storm.

Choice B reason: Lethargy, confusion, and bradycardia are not typical indicators of a thyroid storm. These symptoms might be present in other conditions but are not generally associated with the severe hypermetabolic state seen in thyroid storms.

Choice C reason: Bradycardia, hypotension, and low urine output are also not typical signs of a thyroid storm. Bradycardia (slow heart rate) and hypotension (low blood pressure) are more likely associated with severe hypothyroidism or other conditions, not the hyperactive state of a thyroid storm.

Choice D reason: Fever, tachycardia, and tremors are classic signs of a thyroid storm. A thyroid storm is a life-threatening condition characterized by an excessive amount of thyroid hormones, leading to hypermetabolic activity. This results in symptoms like a high fever, rapid heart rate (tachycardia), and tremors.
