A nurse is planning to administer ceftriaxone IM to an adult client. Which of the following actions should the nurse plan to take?
Administer the medication using a 5/8-inch needle.
Administer the medication using a Z-track technique.
Administer the medication in the deltoid muscle.
Administer the medication at a 45° angle.
The Correct Answer is B
A) Administer the medication using a 5/8-inch needle:
Ceftriaxone is typically administered using a longer needle to ensure proper injection into the muscle. A 5/8-inch needle is more suitable for subcutaneous injections rather than intramuscular (IM) injections.
B) Administer the medication using a Z-track technique:
The Z-track technique is appropriate for IM injections of medications like ceftriaxone, which can be irritating to tissues. This technique helps prevent the medication from leaking into the subcutaneous tissue and minimizes discomfort by creating a zigzag path in the muscle.
C) Administer the medication in the deltoid muscle:
Ceftriaxone is generally administered in larger muscle groups, such as the vastus lateralis or gluteus muscle, rather than the deltoid. The deltoid is more commonly used for vaccines or smaller volume injections.
D) Administer the medication at a 45° angle:
For IM injections, the needle should be inserted at a 90° angle to the skin. A 45° angle is more appropriate for subcutaneous injections.

Correct Answer is D
Explanation
D) Trough:
The trough level of a medication is the lowest concentration of the drug in the bloodstream before the next dose is administered. Monitoring the trough level helps ensure that the medication stays within a therapeutic range, minimizing the risk of toxicity and ensuring effectiveness.
A) Half-life:
Half-life refers to the time it takes for the concentration of a drug in the blood to decrease by half. It is related to how long the drug stays in the system but does not specifically indicate the lowest concentration.
B) Peak:
The peak level is the highest concentration of the drug in the bloodstream after administration. It is used to assess the maximum effect of the drug, not the lowest concentration.
C) Toxic:
Toxic level refers to the concentration of a drug at which it can cause adverse effects or toxicity. It is not related to the lowest concentration but rather to potentially harmful levels.
Correct Answer is ["0.2"]
Explanation
Calculating the Morphine Sulfate Dose:Problem: Administer 2 mg of morphine sulfate IV bolus. The available concentration is 10 mg/mL.
Steps:
Set up a proportion:
We want to find the number of milliliters (mL) needed.
We know the desired dose (2 mg) and the concentration of the medication (10 mg/mL).
Proportion:
x mL / 2 mg = 1 mL / 10 mg
Cross-multiply:
10x = 2
Solve for x:
x = 2 / 10
x = 0.2
Answer: The nurse should administer 0.2 mL of morphine sulfate per dose.
