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
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 D
Explanation
D. Muscle weakness is a hallmark sign of hypokalemia. Potassium is crucial for proper muscle contraction, and low levels can impair muscle function. This weakness can affect skeletal muscles (resulting in fatigue, cramps, or generalized weakness) as well as smooth muscles (contributing to constipation or other gastrointestinal symptoms).
A. Hypokalemia is not typically associated with hyperactive bowel sounds.
B. Cerebral edema is not typically associated with hypokalemia. Instead, cerebral edema can occur with conditions such as hyponatremia (low sodium levels) or other metabolic disturbances.
C. Hypokalemia is more commonly associated with hypotension (low blood pressure) rather than hypertension. Low potassium levels can affect vascular smooth muscle tone, potentially leading to vasodilation and hypotension.
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
