A client's calcium level is 9.5 mg/dL (Normal 9.0-10.5 mg/dL). A nurse would expect the client's phosphate level to be:
high
the same as the calcium level
low
normal
The Correct Answer is D
A. High: The relationship between calcium and phosphate is inverse, meaning when calcium levels rise, phosphate levels tend to decrease, and vice versa. Therefore, the phosphate level would not be expected to be high if the calcium level is within the normal range.
B. The same as the calcium level: While calcium and phosphate levels are related, they do not typically mirror each other directly. They have an inverse relationship, not a one-to-one correlation.
C. Low: Since calcium and phosphate have an inverse relationship, a normal calcium level generally indicates that phosphate levels are also normal, not necessarily low.
D. Normal: With a calcium level of 9.5 mg/dL, which is within the normal range, it is expected that the phosphate level would also be within the normal range, as long as there are no other underlying conditions affecting these levels.

Correct Answer is D
Explanation
A. Slices of smoked ham with potato salad: Smoked ham is high in sodium, hence inappropriate for someone on a restricted sodium diet. Potato salad, depending on preparation, can also be high in sodium due to added salt or processed ingredients.
B. Bowl of tomato soup with a grilled cheese sandwich: Both tomato soup and a grilled cheese sandwich often contain high amounts of sodium, especially if made with canned soup or processed cheese. This would not be suitable for a restricted sodium diet.
C. Salami and cheese on whole wheat crackers: Both salami and cheese are high in sodium, making this a poor choice for someone following a restricted sodium diet.
D. Grilled chicken breast with glazed carrots: Grilled chicken breast is a lean protein with minimal sodium, and glazed carrots, if prepared without added salt or high-sodium ingredients, can be a suitable option. This meal aligns with a restricted sodium diet.
Correct Answer is B
Explanation
A. They become acidic: Acidity is defined by a higher concentration of hydrogen ions (H+), so a decreased concentration of hydrogen ions would not lead to acidity. Acidic fluids have a higher H+ concentration, not a lower one.
B. They become alkaline: A decreased concentration of hydrogen ions (H+) leads to an increase in pH, making the fluids more alkaline. Alkaline conditions are characterized by a lower H+ concentration, resulting in a higher pH level.
C. Carbon ions are retained: Carbon ions do not directly relate to the concentration of hydrogen ions in body fluids. The primary ions involved in acid-base balance are hydrogen ions and bicarbonate ions, not carbon ions.
D. Oxygen ions are released into the blood: Oxygen ions do not have a direct relationship with the concentration of hydrogen ions in the body. The release of oxygen into the blood is related to respiratory function and hemoglobin, not hydrogen ion concentration.
