A nurse is preparing to administer cefadroxil oral suspension 15 mg/kg PO to a client who weighs 98 lb. Available is cefadroxil 250 mg/5 mL. Which of the following actions should the nurse take first?
Round the amount to be administered to the nearest whole number.
Calculate the dosage in milligrams.
Calculate the dosage in milliliters.
Convert the client's weight to kilograms.
The Correct Answer is D
Choice A rationale:
Rounding the amount to be administered to the nearest whole number is a step that may be necessary, but it should not be the first action taken. The nurse should first ensure that the dosage calculation is accurate and based on the client's weight in kilograms. Once the dosage in milligrams is calculated, rounding can be considered.
Choice B rationale:
Calculating the dosage in milligrams is an essential step, but it is not the first action the nurse should take. To determine the correct dosage in milligrams, the nurse needs to convert the client's weight from pounds to kilograms first, as the medication order is given in milligrams per kilogram.
Choice C rationale:
Calculating the dosage in milliliters is not the first action to take because the medication is available in milligrams, and the order is based on weight in kilograms. Converting the weight to kilograms is the initial step to ensure that the dose is calculated correctly.
Choice D rationale:
Converting the client's weight to kilograms is the first and most crucial step in this dosage calculation. The medication order is given in milligrams per kilogram, and the client's weight is provided in pounds. To ensure accurate dosing, the nurse must convert the weight to kilograms, as this is the foundation for calculating the correct dosage in milligrams.

Correct Answer is C
Explanation
Choice A rationale:
The National Student Nurses Association is primarily focused on students and recent graduates. While it can be an excellent organization for student nurses, it may not provide opportunities for a nurse looking to become involved in nursing on a national level beyond their student years.
Choice B rationale:
The National Academy of Medicine is an organization that focuses on health policy and research. While it is a prestigious organization, it is not specifically a nursing organization, and its focus may not align with the goals of a nurse seeking to become more involved in nursing on a national level.
Choice C rationale:
The American Nurses Association (ANA) is a national organization specifically dedicated to advancing the nursing profession. It offers various opportunities for nurses to get involved in national-level nursing advocacy, policy development, and professional growth. Joining the ANA is a suitable choice for a nurse looking to make a national impact in the field of nursing.
Choice D rationale:
The National League for Nursing (NLN) is an organization that primarily focuses on nursing education. While it plays a crucial role in the field of nursing, its focus is more on education and may not align with a nurse's goal to become involved in nursing on a national level from a broader perspective.
Correct Answer is ["A","B","C","D"]
Explanation
Findings that Could Increase Susceptibility to Infection:
-
Budesonide 6 mg PO daily:
- Explanation: Budesonide is a corticosteroid used to reduce inflammation, often prescribed for conditions like Crohn's disease. While it helps manage inflammation, corticosteroids also suppress the immune system. This immunosuppressive effect can increase the client's susceptibility to infections.
-
BMI of 16:
- Explanation: A BMI of 16 is considered underweight. Malnutrition or being underweight can weaken the immune system, making a person more susceptible to infections because their body lacks the necessary nutrients and energy to support immune function.
-
History of Type 2 Diabetes Mellitus:
- Explanation: Diabetes, particularly if not well-controlled, can impair the immune system and increase the risk of infections. High blood sugar levels can hinder the function of immune cells, making it easier for infections to develop and harder for the body to fight them.
-
New Diagnosis of Crohn's Disease:
- Explanation: Crohn's disease is an inflammatory bowel disease that causes inflammation of the digestive tract. This chronic inflammation can affect the body's ability to absorb nutrients, leading to nutritional deficiencies that impair the immune system. Additionally, the disease itself, especially when active, can increase the risk of infection.
Findings That Do Not Increase Susceptibility to Infection:
-
Hematocrit (Hct) of 47%:
- Explanation: The Hct level is within the normal range of 37% to 52%. It measures the percentage of red blood cells in the blood. Since it's normal, it does not indicate an increased risk of infection.
-
Hemoglobin (Hgb) of 16 g/dL:
- Explanation: The Hgb level is also within the normal range of 12 to 18 g/dL. Hemoglobin is a protein in red blood cells that carries oxygen. This normal level does not suggest a higher risk of infection.
-
Potassium level of 3.6 mEq/L:
- Explanation: Potassium levels are within the normal range of 3.5 to 5.0 mEq/L. This electrolyte level is unrelated to infection risk in the context provided.
