A nurse is caring for a client who is to receive liquid medications via a gastrostomy tube. The client is prescribed phenytoin 250 mg. The amount available is phenytoin oral solution 25 mg/5 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["50"]
To calculate the mL of phenytoin oral solution needed for a 250 mg dose, we can use the following equation:
Dose (mg) = Volume (mL) × Concentration (mg/mL)
Given:
Dose = 250 mg
Concentration = 25 mg/5 mL
We need to find the volume (mL):
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Volume (mL) = 250 mg / (25 mg/5 mL)
Volume (mL) = 250 mg / (5 mg/mL)
Volume (mL) = 50 mL
So, the nurse should administer 50 mL of phenytoin oral solution per dose.

Correct Answer is A
Explanation
A) Vaccinations to prevent pneumococcal and Haemophilus influenzae type B meningitis are available.
Explanation: This statement is true. Vaccinations to prevent certain types of bacterial meningitis are available. Pneumococcal and Haemophilus influenzae type B (Hib) vaccines are included in routine childhood immunization schedules to protect against the bacteria that can cause meningitis and other serious infections. These vaccines have significantly reduced the incidence of bacterial meningitis in infants and children.
B) Often a genetic predisposition to meningitis is found.
Explanation: This statement is generally false. While there may be some genetic factors that influence susceptibility to infections, including meningitis, genetic predisposition is not a primary consideration when discussing the risk of meningitis. Meningitis is more commonly caused by bacterial or viral infections, and genetic predisposition is not a significant factor in its occurrence.
C) Meningitis rarely occurs during infancy.
Explanation: This statement is false. Meningitis can occur in infants, including newborns. In fact, infants are one of the age groups at higher risk for meningitis due to their underdeveloped immune systems and susceptibility to infections. Bacterial meningitis, in particular, can be severe and life-threatening in infants.
D) Vaccination to prevent all types of meningitis is now available.
Explanation: This statement is not entirely accurate. While vaccinations are available to prevent certain types of bacterial meningitis (such as pneumococcal and Hib meningitis), there is no single vaccine that can prevent all types of meningitis. Meningitis can be caused by various bacteria, viruses, and other pathogens, and the vaccines target specific ones. It's important for caregivers to ensure that their infants receive recommended vaccines to protect against the most common causes of meningitis.
Correct Answer is A
Explanation
A) Heat intolerance.
Explanation: This statement is true. Heat intolerance is a common symptom of hyperthyroidism, including Graves' disease. People with hyperthyroidism often have an overactive thyroid gland that produces an excessive amount of thyroid hormones. This can lead to an increased metabolic rate, which in turn makes them sensitive to heat. They may feel excessively warm, sweat more than usual, and have difficulty tolerating hot weather.
B) Weight gain.
Explanation: This statement is false. Weight gain is not a typical finding in Graves' disease or hyperthyroidism. In fact, one of the hallmark symptoms of hyperthyroidism is unexplained weight loss despite increased appetite. The elevated levels of thyroid hormones cause an increase in metabolism, leading to weight loss.
C) Bradycardia.
Explanation: This statement is false. Bradycardia refers to an abnormally slow heart rate, typically below 60 beats per minute. In hyperthyroidism, the heart rate is often elevated rather than slowed down. The excessive thyroid hormones can lead to an increased heart rate (tachycardia) and palpitations. It's important to note that if the question were about hypothyroidism (underactive thyroid), bradycardia might be more relevant.
D) Lethargy.
Explanation: This statement is false. Lethargy, or a state of extreme tiredness and lack of energy, is more commonly associated with hypothyroidism (underactive thyroid) rather than hyperthyroidism. Hyperthyroidism usually leads to symptoms of increased energy, restlessness, and hyperactivity due to the elevated metabolic rate caused by excess thyroid hormones.
