A client who weighs 110 pounds receives a prescription for dalteparin 150 units/kg subcutaneously daily for 4 months. The medication is available in 7,500 units/0.3 mL prefilled syringe. How many mL should the nurse administer?
(Enter numerical value only.)
The Correct Answer is ["0.3"]
To calculate the mL of dalteparin to administer, we need to determine the total number
of units required for the client and then convert it to the volume based on the concentration provided.
First, we need to calculate the total number of units required: Weight of the client: 110 pounds
Dalteparin dosage: 150 units/kg Duration of treatment: 4 months
To convert the client's weight from pounds to kilograms, we divide it by 2.2: 110 pounds / 2.2 = 50 kilograms
Next, we calculate the total number of units required:
150 units/kg * 50 kilograms = 7,500 units
Now we can calculate the volume to administer:
7,500 units / 7,500 units/0.3 mL = 0.3 mL
Therefore, the nurse should administer 0.3 mL of dalteparin.

Correct Answer is C
Explanation
In this scenario, the child with a congenital heart defect is presenting with a fever and an
earache. The mother expresses concern about the child's weight and height being at the 5th percentile for his age. Given the child's medical history of a congenital heart defect, it is important for the nurse to address the mother's concerns and provide an accurate response.
The response that states "His smaller size is probably due to the heart disease" is appropriate because children with congenital heart defects may experience growth and developmental delays. Heart defects can affect the child's ability to obtain sufficient nutrients for growth, leading to slower weight and height gain. By acknowledging the relationship between the child's heart disease and his smaller size, the nurse provides the mother with an explanation for the child's growth pattern and helps alleviate concerns.
The other response options are not appropriate or helpful. Asking about the child's mental abilities or implying that the mother has not been feeding the child adequately can be perceived as judgmental or dismissive.
Correct Answer is D
Explanation
Acute kidney injury (AKI) can have significant impacts on the client's fluid and electrolyte balance. Mannitol, a diuretic, is commonly used to promote diuresis and increase urine
output in cases of AKI. However, it is essential to assess the client's hemodynamic status and overall condition before administering mannitol.
Obtaining vital signs (such as blood pressure, heart rate, respiratory rate, and temperature) helps evaluate the client's baseline status and monitor for any changes that may occur after administering mannitol. It is particularly important to assess blood pressure as mannitol can potentially cause hypotension as a side effect.
Assessing breath sounds is also crucial because pulmonary edema can occur as a complication of AKI. Mannitol administration may exacerbate this condition. Therefore, assessing breath sounds allows the nurse to monitor for signs of fluid overload, such as crackles or wheezes.
Collecting a clean catch urine specimen may be necessary for diagnostic purposes to assess kidney function and determine the presence or severity of acute kidney injury. However, obtaining vital signs and assessing breath sounds should be the first nursing intervention before administering any medication, including mannitol, to ensure the client's safety and monitor for any potential adverse effects.
