Correct Answer: A

Rationale: Step-by-step rationale for the correct answer (A): 1. Increased RBC: Hemolytic anemia leads to increased RBC production as the body compensates for the destruction of red blood cells. 2. Decreased bilirubin: Bilirubin levels decrease due to the accelerated breakdown of red blood cells. 3. Decreased Hgb and Hct: Hemolysis causes a decrease in hemoglobin and hematocrit levels as red blood cells are destroyed. 4. Increased reticulocytes: Reticulocytes are immature red blood cells released by the bone marrow in response to increased RBC destruction. Summary: - Choice B is incorrect as hemolytic anemia would lead to increased, not decreased, bilirubin levels. - Choice C is incorrect as hemolytic anemia would lead to decreased, not increased, Hgb and Hct levels. - Choice D is incorrect as hemolytic anemia would not lead to increased levels of all parameters

Correct Answer: C

Rationale: The correct answer is C: 0.45% saline. This solution is hypotonic because it has a lower osmolarity compared to the intracellular fluid. It contains fewer solutes than the cells, causing water to move into the cells by osmosis, potentially causing them to swell. Normal saline (A) and Ringer's lactate (B) are isotonic solutions, meaning they have a similar osmolarity to the intracellular fluid and do not cause significant water shifts. 5% dextrose in normal saline (D) is a hypertonic solution, containing more solutes than the cells, leading to water movement out of the cells.

Correct Answer: C

Rationale: The correct answer is C: Raw fruits and vegetables. Patients with HIV and diarrhea should avoid raw fruits and vegetables due to their high fiber content, which can exacerbate diarrhea symptoms. Fiber can increase bowel movements and worsen diarrhea. Therefore, avoiding raw fruits and vegetables can help reduce diarrhea. Choice A (Potassium-rich food) is not the best answer because potassium-rich foods are important for patients with HIV to maintain electrolyte balance. Choice B (Liquid nutritional supplements) can actually be beneficial in providing essential nutrients to patients with HIV. Choice D (Frozen products) is not directly related to diarrhea management in patients with HIV.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): A complete blood count (CBC) is used to identify abnormalities in red blood cells, white blood cells, and platelets. Hematocrit (HCT) and hemoglobin (Hb) levels are part of a CBC and indicate the oxygen-carrying capacity of the blood. Abnormally low HCT and Hb levels can signify conditions like anemia, which can impact a client's ability to undergo surgery due to potential complications related to oxygen delivery. Summary of Incorrect Choices: A: Potential hepatic dysfunction is not directly related to a CBC, and BUN/creatinine levels are markers for kidney function, not liver function. B: Low levels of urine constituents are not assessed in a CBC, which focuses on blood components. D: Electrolyte imbalance is not specifically tested in a CBC; it is usually evaluated through separate blood tests. Coagulation factors are not directly measured in a CBC.

Correct Answer: C

Rationale: The correct answer is C: Slowing ventilation. The lungs regulate acid-base balance by controlling carbon dioxide levels through ventilation. Increasing ventilation helps expel excess carbon dioxide, thus regulating pH. Slowing ventilation would lead to CO2 buildup and an imbalance in acid-base levels. Excreting HCO3- into the blood (choice A) helps maintain pH, while increasing ventilation (choice D) aids in removing excess CO2. Therefore, slowing ventilation is the exception as it would disrupt the acid-base balance by not effectively regulating carbon dioxide levels.
