Chapter 34: Problem 287

A 0.7-mL oral dose of liquid medication is ordered for an infant. In which device should the nurse measure the dose for administration? A. \(2 \mathrm{~mL}\) syringe B. Tuberculin syringe C. Infant teaspoon D. Medicine cup

Short Answer

Expert verified
B. Tuberculin syringe

Step by step solution

01

Understanding the Units

The prescribed dose is 0.7 mL. Identify which devices are typically used to measure small volumes accurately.
02

Evaluating Each Option

Review each device's capacity and accuracy for measuring small volumes:- A. 2 mL syringe: Suitable for volumes up to 2 mL, accurate for small doses.- B. Tuberculin syringe: Typically 1 mL with fine graduation, very precise for small doses.- C. Infant teaspoon: Usually measures 5 mL, not precise for 0.7 mL.- D. Medicine cup: Generally measures larger volumes (5-30 mL), not precise for 0.7 mL.
03

Selecting the Most Suitable Device

Choose the device that can measure 0.7 mL accurately. Based on the evaluations:- The 2 mL syringe and the tuberculin syringe are both suitable options. However, the tuberculin syringe, with its finer graduation, is the preferred choice for precision.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

medication measurement devices
When it comes to giving medication to infants, selecting the appropriate measurement device is critical for ensuring the accurate dosage. There are several common devices used for this purpose:
  • Syringes: These are the most reliable for precise dosing. Syringes come in various sizes, including 1 mL, 2 mL, and beyond.
  • Medicine Cups: These are typically used for larger volumes but may not be ideal for small doses as they lack the precision needed for tiny amounts.
  • Measuring Spoons: Often used for liquid medicines but usually measure larger volumes (like 5 mL), making them unsuitable for small doses.
  • Droppers: These can be used for small doses but may not be as accurate as syringes.
To ensure your infant gets the correct dose, always choose the device that offers the highest precision for the specific amount of medication required.
tuberculin syringe
A tuberculin syringe is an essential tool in pediatric medication dosing. This type of syringe is typically graduated in 0.01 mL increments and can measure up to 1 mL. This small incremental measurement allows for very accurate dosing, which is crucial for infants. Unlike larger syringes or other measurement devices like medicine cups, the tuberculin syringe provides a much finer precision. This is why, in situations where a very small amount like 0.7 mL is needed, a tuberculin syringe is the preferred choice. Its design makes it particularly suitable for delicate administrations, ensuring that the dosage given is exactly what was prescribed.
accurate dosing in pediatrics
Accurate dosing in pediatrics is essential for the safety and effectiveness of the medication. Infants and children have smaller bodies, and even a slight error in medication dosage can have significant consequences. Therefore, healthcare providers must adhere to several best practices:
  • Use Precise Measurement Tools: Devices like the tuberculin syringe help ensure exact dosages.
  • Double-Check Calculations: Always verify the calculated dose to avoid human error.
  • Follow Prescription Guidelines: Ensure the dosage aligns with the doctor's orders and the medicine's guidelines.
By using precise tools and double-checking dosages, we can minimize the risks associated with medication administration in children.
medicine dosing accuracy
Medicine dosing accuracy is fundamental in any medical treatment, but especially so in pediatric care due to the smaller doses involved. Why does dosing accuracy matter so much?
  • Effectiveness: The right dose ensures the medicine works as intended.
  • Safety: Overdosing can cause adverse effects, while underdosing may render the treatment ineffective.
  • Minimizing Side Effects: Accurate dosing helps to mitigate potential side effects that can arise from improper dosing.
To achieve this accuracy, here are some best practices:

  • Detailed Instructions: Always follow the medication's dosing instructions precisely.
  • Regular Training: Healthcare providers should receive ongoing training in pediatric dosing techniques.
  • Quality Assurance: Utilize measurement devices known for their high precision and reliability like tuberculin syringes.
Ensuring medicine dosing accuracy protects the health and well-being of patients, particularly the most vulnerable, like infants and young children.

Which of the following is a common postoperative cause of airway obstruction? A. Difficult intubation B. Facial edema C. PO2 greater than 60 mmHg D. Tongue blocking the airway

Why are clients who have had back surgery, such as a laminectomy or spinal fusion, turned by log rolling? A. Guard against wound dehiscence B. Prevent excess pressure on the operative site C. Maintain body alignment D. Protect against skin breakdown

Due to an allergy to cats, a client has had several allergy attacks after visiting a family member. The physician has prescribed an antihistamine to reduce the symptoms. The client asks the nurse when would be the best time to take the antihistamine. The nurse's response is based on the knowledge that antihistamines A. transfer the allergic response to a mast cell. B. destroy the allergen that caused the symptoms C. block histamine from attaching to receptor sites. D. destroy histamine, the cause of allergic symptoms.

During discharge teaching, a client asks the nurse how the prescribed antacids relieve heart burn. The nurse鈥檚 response should be based on the knowledge that antacids work by A. decreasing the secretion of gastric acid. B. coating the stomach lining. C. thickening the mucus secreted by the stomach wall. D. neutralizing the acid present in the stomach.

A child is admitted to the hospital with gastroenteri- tis. The physician orders D51/4 NS with 20 mEq KCL per 1000 ml to be administered at a rate of 50 ml per hour. The appropriate nursing action for this order would be to A. delay adding the KCL until the child has voided. B. ask why the physician didn鈥檛 include other elec- trolytes. C. question the physician why a hypertonic solution was ordered. D. monitor the child for fluid volume overload because of the fast rate. The answer is A. Potassium would not be added until the child has voided. Hyperkalemia would occur if kidney func- tion was impaired resulting in cardiac dysfunction. The other responses are incorrect. Fluid replacement is the main concern in gastroenteritis, the fluid is hypotonic and the rate is not excessive.
