The healthcare provider prescribes dalteparin 200 units/kg SUBQ once a day for a client who weighs 154 lb. The medication is available in 25,000 units/mL vial. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.6"]
Rationale:
- Convert the client's weight from pounds (lb) to kilograms (kg).
Weight in kg = 154 lb / 2.2 lb/kg
= 70 kg.
- Calculate the total desired dose in units.
Desired dose (units) = Desired dose (units/kg) × Weight (kg)
= 200 units/kg × 70 kg
= 14000 units.
Available concentration of the medication = 25,000 units/mL.
- Calculate the volume in milliliters (mL) to administer.
Volume (mL) = Desired dose (units) / Available concentration (units/mL)
= 14000 units / 25000 units/mL
= 0.56 mL.
- Round the answer to the nearest tenth.
= 0.6.

Correct Answer is ["75"]
Explanation
Dose per administration in milliliters = 15 mL.
Concentration of the medication = 12.5 mg/5 mL.
- Calculate the amount of medication in milligrams (mg) per administration.
Amount per administration (mg) = Dose per administration (mL) × (Concentration (mg) / Volume (mL))
= 15 mL × (12.5 mg / 5 mL)
= 15 mL × 2.5 mg/mL
= 37.5 mg.
- Determine the number of doses per day.
Doses are given every 12 hours, so Number of doses per day = 24 hours / 12 hours/dose
= 2 doses/day.
- Calculate the total daily dose in milligrams (mg).
Total daily dose (mg) = Amount per administration (mg) × Number of doses per day
= 37.5 mg × 2 doses
= 75 mg.
Correct Answer is D
Explanation
A. Abdominal cramping: Abdominal cramping can be a common symptom of gastritis and may not necessarily require immediate reporting unless it is severe or accompanied by other concerning symptoms.
B. Low grade fever: A low-grade fever can occur with gastritis as part of the inflammatory response, but it is not an immediate concern unless it persists or worsens. It is generally not as urgent as other symptoms.
C. Bruising of the skin: Bruising is not a typical symptom of gastritis. It may be indicative of a bleeding disorder or other underlying issues unrelated to the gastrointestinal system. However, it is not directly associated with gastritis.
D. Bloody emesis: Bloody emesis (vomiting blood) is a critical sign that indicates possible gastrointestinal bleeding, which can occur with severe gastritis. This is an emergency situation and should be reported immediately as it requires urgent medical attention.
