Question

The physician has ordered Terbutaline (Brethine). To ensure correct administration of this medication, the nurse should obtain which of the following? ? A. A 2-inch needle ? B. An 18-gauge needle ? C. A 1-inch needle ? D. A 2.5-inch needle

Short answer

Answer: A 1-inch needle is the correct choice for administering Terbutaline (Brethine) through a subcutaneous injection, as it provides the right balance between length for proper penetration of the fatty tissue and minimal discomfort for the patient.

Step-by-step solution

Understanding the medication

Terbutaline (Brethine) is a medication generally used to treat asthma and chronic obstructive pulmonary diseases such as bronchitis and emphysema. It is a bronchodilator that helps to relax the muscles in the airways and increase airflow to the lungs, making it easier to breathe. It is usually administered through an injection called a subcutaneous injection, which is given in the fatty layer of tissue under the skin. For this type of injection, a short and thin needle is preferred.

Analyzing each option

Now, let's analyze each option and determine if it's suitable for administering Terbutaline (Brethine). A. A 2-inch needle: This is too long for a subcutaneous injection as it can reach deeper tissues and potentially cause damage or deliver the medication to an incorrect location. B. An 18-gauge needle: The gauge refers to the thickness or diameter of the needle. An 18-gauge needle is quite thick and therefore would cause more pain and discomfort during the injection. In addition, a thicker needle is not necessary for subcutaneous injections as there is no need to puncture deep tissues. C. A 1-inch needle: This needle length seems appropriate for a subcutaneous injection, as it is long enough to penetrate the fatty tissue without going too deep. Since we don't know the gauge, we should analyze the last option before making conclusions. D. A 2.5-inch needle: The length of the needle is not suitable, as it is too large, increasing the chances of reaching deeper tissues and causing unnecessary pain or damage.

Selecting the correct option

Based on our analysis of the options, the correct choice is C. A 1-inch needle. This option is suitable for administering Terbutaline (Brethine) through a subcutaneous injection as it provides the right balance between length for proper penetration of the fatty tissue and minimal discomfort for the patient.

Key concepts

Subcutaneous Injection

Subcutaneous injections are a common method of administering medications directly into the fatty tissue layer beneath the skin. This route is particularly useful for drugs that require slow, continuous absorption into the bloodstream.

The technique involves using a short needle,typically between 1/2 inch to 5/8 inch in length, inserted at a 45 to 90-degree angle, depending on the amount of subcutaneous tissue present and the patient's body build. A 1-inch needle can also be appropriate, especially for individuals with more adipose tissue.

When preparing to give a subcutaneous injection, it is essential to select the correct needle size to ensure effective absorption while minimizing patient discomfort. Needle gauge is equally important, with a higher gauge indicating a thinner needle. Common gauges for subcutaneous injections range from 25 to 30. The site for injection is also a key consideration, with common areas including the upper arm, abdomen, and thigh, as these locations usually have sufficient fatty tissue.

Proper administration technique and site rotation are important to avoid tissue damage and promote better medication absorption.

Terbutaline (Brethine)

Terbutaline, known by the brand name Brethine, is a bronchodilator medication that is used to relieve symptoms of asthma and other similar pulmonary conditions. It works by relaxing the muscles in the walls of the small air passages in the lungs. This helps to open the airways and make breathing easier for individuals experiencing bronchospasms.

Terbutaline can be administered subcutaneously, orally, or through inhalation, but when given as a subcutaneous injection, it allows for quick onset of action, which is particularly useful in cases of acute bronchospasm. The dosage and frequency of administration depend on the specific patient's needs and the prescribing physician's instructions.

As with any medication, monitoring for potential side effects is crucial. Side effects of terbutaline may include tremors, nervousness, dizziness, and increased heart rate. Nurses administering this medication should be aware of the signs of overdose and be prepared to support the patient in case of adverse reactions. Nursing considerations include monitoring respiratory status, heart rate, and the patient's response to the medication.

NCLEX-PN Exam Preparation

The National Council Licensure Examination for Practical Nurses (NCLEX-PN) is a standardized test that all aspiring practical nurses must pass to obtain licensure. Preparing for this exam is critical to a nursing student's career.

Effective preparation strategies include a thorough review of nursing content, particularly pharmacology, patient care, infection control, therapeutic procedures, and the nursing process. Utilizing various study materials such as review books, practice questions, and simulation exams can help students familiarize themselves with the exam format and question style.

Time management skills are also essential when taking the NCLEX-PN. Students should practice answering questions within the allotted time to improve their ability to think critically under pressure. Lastly, it's important for students to understand the procedures for safe medication administration, as this is a significant part of the exam. Familiarizing oneself with different injection techniques, including subcutaneous injection, as well as indications, dosages, and side effects of common medications like Terbutaline, ensures a well-rounded preparation for the NCLEX-PN exam.
