A nurse is reviewing a client's prescription for terbutaline 0.25 mg subcutaneous every 4 hr for 24 hr PRN more than four uterine contractions per hour. How should the nurse interpret this prescription?

The nurse should administer terbutaline each time the client has more than four contractions in hr

The nurse should begin administering terbutaline every 4 hr for 24 hr

The nurse should administer terbutaline once every 24 hr to prevent the client from having more than four contractions per hour.

The nurse should wait until the client has more than four contractions in 1 hr before administering terbutaline.

Answer and Explanation

The Correct Answer is D

A) The nurse should administer terbutaline each time the client has more than four contractions in an hour: This interpretation is incorrect because the prescription is for PRN (as needed) administration based on the occurrence of more than four uterine contractions per hour, not every time the client has more than four contractions. The medication should not be administered automatically at each instance of more than four contractions, but rather when it is specifically indicated as per the prescribed instructions.

B) The nurse should begin administering terbutaline every 4 hr for 24 hr: This interpretation is not accurate because the prescription does not state that terbutaline should be given regularly every 4 hours regardless of the client's condition. Instead, it specifies that terbutaline should be administered as needed (PRN) only when the client has more than four uterine contractions per hour. Routine administration every 4 hours is not appropriate unless specified in the prescription.

C) The nurse should administer terbutaline once every 24 hr to prevent the client from having more than four contractions per hour: Administering terbutaline on a fixed schedule every 24 hours is not consistent with the prescription. The prescription specifically indicates that terbutaline is only to be administered as needed (PRN) when the client is experiencing more than four contractions per hour.

D) The nurse should wait until the client has more than four contractions in 1 hr before administering terbutaline: This interpretation aligns with the prescription. Terbutaline is to be administered only when the client has more than four uterine contractions in one hour, and this should be done on a PRN basis. The medication is intended to manage excessive uterine activity, and its administration should be based on the client's current condition (i.e., the presence of more than four contractions per hour), not preemptively or on a regular schedule.

Correct Answer is ["0.8"]

Explanation

Step 1: Set up the proportion:

Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)

Step 2: Substitute the values:

8 mg / Volume = 10 mg/mL

Step 3: Solve for the unknown volume:

Volume = 8 mg / 10 mg/mL

Step 4: Calculate the volume:

Volume = 0.8 mL

A. Prochlorperazine 25 mg rectal every 12 hr PRN nausea B. Losartan 25 mg every 12 hr C. Docusate sodium 100 mg PO daily D. Ferrous fumarate 150 mg PO dally

Correct Answer is B

Explanation

A) Prochlorperazine 25 mg rectal every 12 hr PRN nausea: Prochlorperazine is an antiemetic commonly used to treat nausea and vomiting. The prescription for prochlorperazine 25 mg rectal every 12 hours as needed (PRN) is appropriate for managing nausea in the postpartum period, especially if the client is unable to tolerate oral medications due to nausea. The route and dosage are typical for this medication, so there is no need for clarification.

B) Losartan 25 mg every 12 hr: Losartan is an angiotensin II receptor blocker (ARB) commonly used to treat hypertension. In the postpartum period, it is generally not recommended as first-line treatment due to the potential for hypotension and the effect of ARBs on renal function, especially in a client who may be postpartum and at risk for fluid shifts, blood loss, or other complications. Additionally, ARBs are usually contraindicated during pregnancy and should be used cautiously or avoided in the immediate postpartum period.

C) Docusate sodium 100 mg PO daily: Docusate sodium is a stool softener commonly prescribed postpartum to prevent constipation, which can be a common issue due to pain medications, decreased mobility, or dehydration. The dose of 100 mg daily is within the recommended range for adult patients and is generally safe for use in the postpartum period. There is no need for clarification on this prescription.

D) Ferrous fumarate 150 mg PO daily: Ferrous fumarate is an iron supplement commonly prescribed postpartum to prevent or treat iron-deficiency anemia, which can result from blood loss during delivery. The dosage of 150 mg daily is a typical and safe prescription to help replenish iron stores and support postpartum recovery. This is a standard prescription and does not require clarification.
