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

Answer and Explanation

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. Ask the client if they would prefer a translator who is the same gender: Offering a professional interpreter of the same gender, when possible, shows cultural sensitivity and promotes client comfort and openness, especially for intimate or personal health discussions.

B. Use a website with a ".com" URL to translate for the client: Websites, especially commercial ones, may be inaccurate or unreliable for medical translation. Miscommunication through these tools can result in errors and compromise client safety.

C. Request a family member of the client to translate: Family members may unintentionally alter or filter information, leading to errors or withholding of critical health data. It also poses confidentiality concerns and is not considered a best practice.

D. Ask a nursing student who speaks the same language as the client to translate: Unless the student is a certified medical interpreter, this action is inappropriate. Medical interpretation requires training to ensure accurate, unbiased communication that upholds privacy and safety.

A. Coarse lung sounds B. Widening pulse pressure C. Muffled heart sounds D. Decreased jugular vein distention

Correct Answer is C

Explanation

Rationale:

A. Coarse lung sounds: Coarse lung sounds are typically associated with pulmonary issues such as fluid overload or pneumonia. They are not specific to cardiac tamponade and may appear later or not at all in this condition.

B. Widening pulse pressure: Cardiac tamponade causes narrowing of the pulse pressure due to decreased stroke volume, not widening. A narrowing pulse pressure is a more reliable hemodynamic sign of tamponade.

C. Muffled heart sounds: Muffled or distant heart sounds are a classic early sign of cardiac tamponade. They result from fluid accumulation in the pericardial sac, which insulates the heart and dampens the transmission of sound.

D. Decreased jugular vein distention: Cardiac tamponade typically causes increased jugular vein distention due to impaired venous return to the heart. A decrease in JVD would not be expected and may indicate a different process.
