A nurse is caring for a client who has a potassium level of 3.2 mEq/L (3.5 to 5 mEq/L). Which of the following foods should the nurse recommend as being the best source of potassium?
1⁄2 cup apple juice
½ cup steamed cauliflower
cup boiled white rice
1 cup cantaloupe
The Correct Answer is D
Rationale:
A. ½ cup apple juice: Apple juice contains a relatively low amount of potassium, making it a poor choice for correcting hypokalemia. It typically provides less than 150 mg per half-cup serving.
B. ½ cup steamed cauliflower: Cauliflower is low in potassium compared to other vegetables. While healthy, it does not significantly contribute to raising potassium levels in the body.
C. 1 cup boiled white rice: White rice has minimal potassium content, especially when boiled. It is not effective in increasing potassium and is typically suitable for clients requiring low-potassium diets.
D. 1 cup cantaloupe: Cantaloupe is high in potassium, offering around 400–500 mg per cup. It is among the best fruit sources for replenishing potassium and is appropriate for clients with mild hypokalemia.

Correct Answer is A
Explanation
Rationale:
A. Methylprednisolone: Methylprednisolone is a corticosteroid, which can increase blood glucose levels by promoting gluconeogenesis and reducing insulin sensitivity. Hyperglycemia is a known adverse effect, especially with prolonged or high-dose use.
B. Ondansetron: Ondansetron is an antiemetic used to control nausea and vomiting. It does not affect glucose metabolism and is not associated with elevated blood glucose as a side effect.
C. Guaifenesin: Guaifenesin is an expectorant that thins mucus to improve airway clearance. It has no effect on blood sugar levels and is not known to interfere with glucose regulation.
D. Amoxicillin: Amoxicillin is a broad-spectrum antibiotic and does not typically cause changes in blood glucose. It is generally well-tolerated in terms of metabolic side effects.
Correct Answer is D
Explanation
Rationale:
A. A 25-gauge needle: A 25-gauge needle is too small and not designed for accessing implanted ports. Using such a needle may cause damage to the port septum and does not ensure reliable blood flow or medication administration.
B. An angiocatheter: Angiocatheters are used for peripheral venous access and are not suitable for accessing implanted ports. Their sharp tips can damage the septum of the port and compromise its integrity.
C. A butterfly needle: Butterfly needles are designed for short-term peripheral access. They are not appropriate for implanted ports and can damage the port’s self-sealing septum, leading to malfunction.
D. A noncoring needle: Noncoring (Huber) needles are specifically designed for accessing implanted venous ports. Their curved tip prevents coring of the port septum, reducing damage and maintaining the port’s function and sterility.
