Answer and Explanation

The Correct Answer is B

A. "Adding pecans will be a change I can readily make.": Pecans are not a significant source of potassium compared to other foods.

B. "I will eat cantaloupe for my morning snack.": Cantaloupe is a potassium-rich food and an excellent choice to increase dietary potassium.

C. "I will miss eating yogurt every day for breakfast.": Yogurt is a good potassium source, so discontinuing it would not help.

D. "I can plan to eat rice instead of baked potatoes.": Rice is low in potassium, whereas baked potatoes are a potassium-rich option.

Correct Answer is A

Explanation

A. Weak pulse: Isotonic fluid-volume deficit results in decreased blood volume, leading to reduced cardiac output and a weak, thready pulse.

B. Distended neck veins: This is associated with fluid volume excess, not deficit.

C. Bradycardia: Fluid deficit typically leads to tachycardia as the body compensates for decreased circulating volume.

D. Pitting edema: This is a sign of fluid overload rather than deficit.

A. Sodium level 140 mEq/L (136-145 mEq/L) B. Magnesium level 1.0 mEq/L (1.3-2.1 mEq/L) C. Calcium level 10 mg/dL (9-10.5 mg/dL) D. Potassium level 3.5 mEq/L (3.5-5 mEq/L)

Correct Answer is B

Explanation

A. Sodium level 140 mEq/L (136-145 mEq/L): This sodium level is within the normal range and is not of concern.

B. Magnesium level 1.0 mEq/L (1.3-2.1 mEq/L): This value is below the normal range, indicating hypomagnesemia, which can cause serious complications such as arrhythmias, neuromuscular irritability, and seizures. This is the most concerning value.

C. Calcium level 10 mg/dL (9-10.5 mg/dL): This calcium level is within the normal range and is not concerning.

D. Potassium level 3.5 mEq/L (3.5-5 mEq/L): This potassium level is at the low end of normal. While it is something to monitor, it is not immediately concerning compared to hypomagnesemia.
