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 A
Explanation
A) Correct- Zidovudine is an antiretroviral medication used in the treatment of HIV infection.
One of the potential side effects of zidovudine is hematological toxicity, including anemia (low red blood cell count) and neutropenia (low white blood cell count). The appearance of pinpoint, red, round spots on the skin could be indicative of petechiae, which are small hemorrhages caused by the leakage of blood into the skin. Petechiae can occur due to low platelet counts, a
component of the complete blood count (CBC). Monitoring the complete blood count is important for clients receiving zidovudine to identify any potential adverse effects on blood cell counts. Anemia and neutropenia can increase the risk of infection, bleeding, and other complications. Therefore, any changes in blood cell counts, including the presence of petechiae, should be reported to the healthcare provider for further evaluation and management.
B) Incorrect- This is used to assess allergic reactions and is not specifically related to the appearance of petechiae.
C) Incorrect- A skin biopsy is typically performed to diagnose skin conditions or diseases and is not the primary assessment to evaluate the cause of petechiae.
D) Incorrect- Electromyography is a diagnostic test used to assess muscle and nerve function and is not relevant to the appearance of petechiae associated with zidovudine use.
Correct Answer is D
Explanation
The correct answer is choice D: Begin chest compressions at 100/minute.
Choice A rationale:
Observing for swelling at the fracture site is not immediately relevant in this emergency situation. The priority is to address the lack of pulse and respiration.
Choice B rationale:
Analyzing the cardiac rhythm in another lead is unnecessary when the patient has no pulse and is not breathing. Immediate life-saving measures are required.
Choice C rationale:
Obtaining a 12-lead electrocardiogram is not the priority in this scenario. The patient needs immediate resuscitation efforts.
Choice D rationale:
Beginning chest compressions at 100/minute is the correct intervention. The absence of a carotid pulse and spontaneous respirations indicates cardiac arrest, and chest compressions are essential to maintain circulation and oxygenation until further help arrives.
