If the nurse needs to administer a 2 mL injection what size syringe is most appropriate to use?

5 mL

1 mL

10 mL

3 Ml

Answer and Explanation

The Correct Answer is A

A. A 5 mL syringe can hold up to 5 mL of fluid. It is suitable for administering 2 mL of medication, as it provides enough capacity with some additional space to ensure accurate measurement and prevent overfilling.

B. A 1 mL syringe is too small for administering a 2 mL injection. It would not accommodate the entire volume, and attempting to draw and administer 2 mL with a 1 mL syringe could result in spillage or inaccurate dosing.

C. A 10 mL syringe is larger than necessary for administering a 2 mL injection. While it can hold the required volume and more, it is bulkier and might be less convenient for administering smaller volumes like 2 mL.

D. A 3 mL syringe can also accommodate a 2 mL injection. However, a 5 mL syringe would provide a more appropriate capacity with a bit of extra space, which can be beneficial for accurate measurement and ease of administration.

Correct Answer is ["A","D"]

Explanation

A. Diarrhea is a common side effect associated with ondansetron, which is used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, and surgery.

B. Ondansetron can potentially cause changes in glucose metabolism, leading to hyperglycemia, especially in clients with diabetes mellitus. Monitoring blood glucose levels is essential during ondansetron administration, particularly in clients who are already predisposed to hyperglycemia.

D. Headache is a potential adverse effect of ondansetron. It is listed as a common side effect and should be monitored, especially in older adults who may be more sensitive to medication effects.

C. Ondansetron can affect the QT interval rather than the PR interval. It may cause QT interval prolongation, which can predispose the client to arrhythmias

A. 0.5-1.5mEq/L B. 1.3-2.1 mEq/L C. 2.5-3.5 mEq/L D. 1.0-3.0 mEq/L

Correct Answer is B

Explanation

B. This range represents the normal serum magnesium level. It is important for maintaining neuromuscular function and other vital processes in the body.

A. This range is too low for normal serum magnesium levels. Magnesium levels below this range can indicate hypomagnesemia, which can lead to symptoms such as muscle cramps, tremors, and cardiac arrhythmias.

C. This range is too high for normal serum magnesium levels. Elevated magnesium levels (hypermagnesemia) can occur in conditions such as renal failure or excessive magnesium intake, leading to symptoms like weakness, decreased reflexes, and in severe cases, cardiac arrest.

D. While this range is broader and includes the correct normal range (1.3-2.1 mEq/L), it also includes values that are below and above normal. Values below 1.3 mEq/L can indicate hypomagnesemia, while values above 2.1 mEq/L can indicate hypermagnesemia.
