The major electrolytes in the extracellular fluid are:

Correct Answer: C

Rationale: The correct answer is C: sodium and chloride. In the extracellular fluid, sodium and chloride are the major electrolytes due to their roles in maintaining fluid balance, nerve function, and muscle contraction. Potassium and phosphate (choice B) are primarily found in intracellular fluid, while potassium and chloride (choice A) are not the major electrolytes in extracellular fluid. Similarly, sodium and phosphate (choice D) are not major extracellular electrolytes. Thus, choice C is the correct answer based on the significant presence and functions of sodium and chloride in the extracellular fluid.

Correct Answer: D

Rationale: The correct answer is D because clients with renal disease may have impaired kidney function, leading to difficulty in regulating potassium levels. High potassium intake can further burden the kidneys, potentially causing hyperkalemia. Clients on diuretic therapy (choice A) may actually need to monitor potassium levels due to potential electrolyte imbalances. Clients with an ileostomy (choice B) typically do not have issues with potassium absorption. Clients with metabolic alkalosis (choice C) may have potassium shifts but do not necessarily need to avoid high-potassium foods unless specifically advised by their healthcare provider.

Correct Answer: A

Rationale: The correct answer is A: variable decelerations. Variable decelerations are abrupt decreases in fetal heart rate that vary in depth, duration, and timing, which can indicate cord compression. The variability in these decelerations suggests that the umbilical cord is being compressed intermittently. Early decelerations (B) are usually caused by head compression during contractions and mirror the contractions, not indicating cord compression. Bradycardia (C) is a slow heart rate, which can be caused by various factors but is not specific to cord compression. Tachycardia (D) is a fast heart rate, which can also be caused by various factors but is not typically associated with cord compression.

Correct Answer: A

Rationale: The correct answer is A: Transfuse neutrophils. Neutrophil transfusion is not a standard treatment for neutropenia as neutrophils do not survive well outside the body. For the other choices: B: Excluding raw vegetables is correct to prevent infection. C: Avoiding rectal suppositories is correct to prevent mucosal injury. D: Prohibiting vases of fresh flowers is correct to prevent exposure to fungal spores. So, transfusing neutrophils is inappropriate as it is not a standard treatment for neutropenia.

Correct Answer: C

Rationale: The correct quadrant for tenderness in suspected appendicitis is the lower right quadrant (Choice C). This is because the appendix is located in the lower right abdomen. Appendicitis typically presents with pain starting around the navel and then localizing to the lower right quadrant. The other choices, upper right (Choice A), upper left (Choice B), and lower left (Choice D) are incorrect as they do not correspond to the typical location of the appendix. Upper right quadrant is where the liver and gallbladder are situated, upper left quadrant contains the stomach and spleen, and lower left quadrant has the colon and left ovary/testis.
