A client who had a knee replacement surgery receives a prescription for enoxaparin 30 mg subcutaneously every 12 hours for 10 days. The medication is available in 30 mg per 0.3 mL prefilled syringes. How many mL should the practical nurse (PN) administer each day? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["0.6"]

Medication dose: 30 mg enoxaparin
Medication concentration: 30 mg per 0.3 mL (prefilled syringe)
Frequency: Every 12 hours
Duration: 10 days

Calculation:

Injections per day: Since the medication is given every 12 hours, the client will receive injections 2 times per day (24 hours / 12 hours/injection).
Total medication per day: To find the total amount of enoxaparin needed per day, multiply the single injection dose by the number of injections:

Total enoxaparin/day = Dose per injection x Number of injections/day = 30 mg/injection x 2 injections/day = 60 mg/day

Volume of medication per day: Now, we need to find the volume of solution needed to deliver the total daily dose (60 mg) based on the medication concentration (30 mg/0.3 mL). We can achieve this with a proportion:

Volume (mL) / Total dose (mg) = Concentration (mg/mL)

Volume (mL) = (Total dose (mg) x Concentration (mL/mg)) / Concentration (mg/mL)

Plugging in the values:

Volume (mL) = (60 mg x 0.3 mL/mg) / 30 mg/mL

Volume (mL) = 18 mL / 30 mL/mL

Simplifying:

Volume (mL) = 0.6 mL

Therefore, the practical nurse (PN) should administer 0.6 mL of enoxaparin each day.

Correct Answer is C

Explanation

A. Pallor is not directly related to low serum calcium levels. It may indicate anemia or other conditions, but it is not a primary concern for hypocalcemia.
B. Bruising is generally associated with clotting issues or trauma, not specifically with low serum calcium. Low calcium can affect clotting, but bruising is not a direct or primary symptom of hypocalcemia.
C. Tetany, which includes symptoms like muscle spasms, twitching, and numbness, is a key indicator of low serum calcium levels. Monitoring for tetany is essential in managing clients with malabsorption syndrome who have hypocalcemia.
D. Jaundice is a sign of liver dysfunction or hemolysis, not directly related to low calcium levels. Low serum calcium is not typically associated with jaundice.

A. "MRSA is not that big of a deal." B. "I should wash my hands and encourage others who are around me to wash their hands." C. "I will no longer be able to transmit MRSA once my surgical site is completely healed." D. "My diet makes a difference in my ability to heal." E. "I should only take antibiotics until I feel better."

Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A"},"C":{"answers":"B"},"D":{"answers":"A"},"E":{"answers":"B"}}

Explanation

"MRSA is not that big of a deal."
No Understanding: MRSA is a serious infection that can be difficult to treat and can spread. It is important for the client to understand the severity of MRSA.
"I should wash my hands and encourage others who are around me to wash their hands."
Understanding: Hand hygiene is critical in preventing the spread of MRSA. The client is aware of the importance of hand washing for infection control.
"I will no longer be able to transmit MRSA once my surgical site is completely healed."
No Understanding: MRSA can be a persistent infection, and healing of the surgical site does not guarantee that MRSA cannot be transmitted. Proper infection control measures must continue.
"My diet makes a difference in my ability to heal."
Understanding: Nutrition plays a role in the healing process and overall recovery. A balanced diet supports the immune system and aids in wound healing.
"I should only take antibiotics until I feel better."
No Understanding: It is crucial to complete the full course of antibiotics as prescribed to ensure the infection is fully treated and to prevent resistance
