A nurse is preparing to administer digoxin to a 6-month-old infant. Prior to administering the dose, the nurse measures the apical heart rate. The nurse should withhold the dose if the infant's apical heart rate is less than what rate?

Answer and Explanation

The Correct Answer is ["90"]

The nurse should withhold the dose if the infant's apical heart rate is less than 90 beats per minute.

Digoxin is a medication that can slow the heart rate. If an infant's heart rate is already too slow, administering digoxin can increase the risk of bradycardia, a serious heart rhythm disturbance.

It's important to monitor the apical heart rate for a full minute before administering digoxin to an infant and to withhold the dose if the heart rate is below the specified threshold.

Correct Answer is ["5.3"]

Explanation

To calculate the dose of acetaminophen, you can use the following formula:

Dose (in mg)= Weight (in kg) × Dose (mg/kg)

First, convert the weight from pounds to kilograms:

Weight (in kg)= Weight (in lb)/ 2.2

Weight (in kg)=28 lb/ 2.2 ≈ 12.73kg

Now, calculate the dose:

Dose (in mg) =12.73 kg × 10 mg/kg ≈ 127.3 mg

Next, determine how many milliliters (mL) of the available acetaminophen solution (120 mg/5 mL) contain the calculated dose:

Volume (in mL)=Dose (in mg)/Concentration (in mg/mL)

Volume (in mL) =127.3 mg/( 120 mg/5 mL)

Volume (in mL)≈127.3 mg / 24 mg/mL ≈ 5.304 mL

Therefore, the nurse should administer approximately 5.3 mL of acetaminophen.

A. "Has your child been exposed to anyone with chicken pox B. "Has any family member had a sore throat within the past few weeks?" C. "Has any family member had a gastrointestinal disorder in the past few weeks? D. "Has your child had difficulty urinating?

Correct Answer is B

Explanation

A. "Has your child been exposed to anyone with chicken pox?"
While chickenpox is caused by a different virus (varicella-zoster virus) and is not directly linked to rheumatic fever, the nurse might inquire about exposure to contagious illnesses as a general part of the assessment.
B. "Has any family member had a sore throat within the past few weeks?"
This question is relevant because rheumatic fever often follows an untreated or inadequately treated group A streptococcal infection, such as strep throat. A sore throat in a family member could indicate the presence of streptococcal infection, which is a crucial factor in the development of rheumatic fever.
C. "Has any family member had a gastrointestinal disorder in the past few weeks?"
Gastrointestinal disorders are not directly associated with the development of rheumatic fever. However, a comprehensive medical history might include questions about recent illnesses to understand the overall health context.
D. "Has your child had difficulty urinating?"
Difficulty urinating is not a typical symptom or risk factor associated with rheumatic fever. This symptom would likely prompt investigation into other potential issues but is not specifically related to rheumatic fever.
