How many mL should the nurse plan to administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.5"]

Desired dose of nalbuphine: 10 mg

Concentration of nalbuphine solution: 20 mg/mL

Step 1: Set up the proportion:

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

Step 2: Substitute the values:

10 mg / Volume = 20 mg/mL

Step 3: Solve for the unknown volume:

Volume = 10 mg / 20 mg/mL

Step 4: Calculate the volume:

Volume = 0.5 mL

Correct Answer is ["167"]

Explanation

Given:

Total volume to be infused: 1,000 mL

Infusion time: 6 hours

Step 1: Calculate the infusion rate:

Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)

Step 2: Substitute the values:

Infusion rate (mL/hr) = 1,000 mL / 6 hr

Step 3: Calculate the infusion rate:

Infusion rate (mL/hr) = 166.6666667 mL/hr

Step 4: Round to the nearest whole number:

Infusion rate (mL/hr) ≈ 167 mL/hr

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.
