A nurse is receiving a telephone prescription from a provider for a client who requires additional medication for pain control. Which of the following entries should the nurse make in the medical record?
"Morphine 3.0 mg sub q every 4 hr PRN for pain."
"Morphine 3 mg subcutaneous every 4 hr PRN for pain."
"Morphine 3 mg SC q 4 hr PRN for pain."
"Morphine 3 mg SQ every 4 hr PRN for pain."
The Correct Answer is B
A. "Morphine 3.0 mg sub q every 4 hr PRN for pain." Including a trailing zero (3.0 mg) is considered unsafe and is discouraged in medication documentation. It increases the risk of a tenfold overdose if the decimal is missed.
B. "Morphine 3 mg subcutaneous every 4 hr PRN for pain." This entry uses the correct dosage format without a trailing zero, the full term "subcutaneous" instead of abbreviations, and proper medical terminology. It adheres to safe documentation practices as per The Joint Commission guidelines.
C. "Morphine 3 mg SC q 4 hr PRN for pain." The abbreviation “SC” is considered unsafe and prone to misinterpretation. Also, "q" for "every" is discouraged in clinical documentation due to potential misreading and error.
D. "Morphine 3 mg SQ every 4 hr PRN for pain." The abbreviation “SQ” can be misinterpreted or mistaken for “5 every” or other terms. Safe practice requires spelling out “subcutaneous” to prevent errors in medication administration.

Correct Answer is C
Explanation
A. Place the client in a side-lying position for the procedure. Paracentesis is typically performed with the client in a high-Fowler’s or upright position, allowing fluid to collect in the lower abdomen for easier drainage.
B. Administer a low-volume hypertonic enema the night before the procedure. An enema is not required for a paracentesis, as the procedure involves the peritoneal cavity, not the bowel.
C. Weigh the client before and after the procedure. Weighing the client helps assess the amount of fluid removed and monitor for fluid shifts. It is a key part of pre- and post-procedural care to evaluate the effectiveness of the intervention.
D. Ensure the client has a full bladder just prior to the procedure. A full bladder increases the risk of injury during needle insertion. The bladder should be emptied before the procedure to prevent accidental puncture.
Correct Answer is A
Explanation
A. Choose a vein that is palpable and straight. A palpable, straight vein provides the best access for successful IV catheter insertion. It allows for easier threading of the catheter and reduces the risk of complications like infiltration.
B. Select a site on the client's dominant arm. The non-dominant arm is usually preferred to minimize interference with daily activities and reduce the risk of dislodgement due to frequent use.
C. Elevate the client's arm prior to insertion. Elevating the arm can decrease venous filling, making veins less prominent and harder to access. Instead, the arm should be placed in a dependent position to promote vein distention.
D. Apply a tourniquet below the venipuncture site. The tourniquet should always be placed above the insertion site to restrict venous return and make the veins more prominent and easier to access.
