1. A client comes to the clinic for assessment of his physical status and guidelines for starting a weight-reduction diet. The client's weight is 216 pounds and his height is 66 inches. The nurse identifies the BMI (body mass index) as:
- A. Within normal limits, so a weight-reduction diet is unnecessary.
- B. Lower than normal, so education about nutrient-dense foods is needed.
- C. Indicating obesity because the BMI is 35.
- D. Indicating overweight status because the BMI is 27.
Correct answer: C
Rationale: Obesity is defined by a BMI of 30 or more with no co-morbid conditions. Body Mass Index (BMI) is calculated by utilizing a chart or nomogram that plots height and weight. In this case, the client's BMI is calculated as 35, indicating obesity. A BMI of 27 falls within the overweight range, not obesity (which starts at 30). Choices A and B are incorrect because a BMI of 35 indicates obesity, not normal limits or being lower than normal. Therefore, the correct answer is C, indicating obesity based on the BMI calculation.
2. The nurse is caring for a 44-year-old client diagnosed with hypoparathyroidism. Which electrolyte imbalance is closely associated with hypoparathyroidism?
- A. Hypocalcemia.
- B. Hyponatremia.
- C. Hyperkalemia.
- D. Hypophosphatemia.
Correct answer: A.
Rationale: The correct answer is Hypocalcemia. In hypoparathyroidism, where the parathyroid glands are not producing sufficient parathyroid hormone, calcium levels become inadequate. This leads to hypocalcemia, characterized by symptoms such as muscle spasms, anxiety, seizures, hypotension, and congestive heart failure. Hyponatremia and hyperkalemia are not typically associated with hypoparathyroidism. While hyperphosphatemia can be seen in hypoparathyroidism due to decreasing calcium levels, the question specifically asks about the primary electrolyte imbalance closely related to hypoparathyroidism, which is hypocalcemia.
3. What are the major electrolytes in the extracellular fluid?
- A. potassium and chloride
- B. potassium and phosphate
- C. sodium and chloride
- D. sodium and phosphate
Correct answer: C
Rationale: The correct answer is sodium and chloride. These two electrolytes are the major components of extracellular fluid. Potassium and phosphate (Choice B) are not the major electrolytes in the extracellular fluid. Potassium is primarily an intracellular ion, and phosphate is more abundant in the intracellular fluid and bones. Sodium and phosphate (Choice D) are also not the major electrolytes in the extracellular fluid. Chloride plays a crucial role in maintaining electrolyte balance and is predominantly found in extracellular fluid alongside sodium.
4. Which of the following is not a primary function of the kidneys?
- A. blood pressure control
- B. vitamin D activation
- C. erythropoietin production
- D. reabsorption of waste products
Correct answer: D
Rationale: The correct answer is reabsorption of waste products because the kidneys excrete waste products rather than reabsorbing them. Choices A, B, and C are indeed primary functions of the kidneys. The kidneys play a crucial role in regulating blood pressure, activating vitamin D, and producing erythropoietin, which stimulates red blood cell production. Therefore, the primary role of the kidneys is to filter blood, remove waste products, regulate fluid balance, and maintain electrolyte balance.
5. While undergoing hemodialysis, the client becomes restless and tells the nurse he has a headache and feels nauseous. Which of the following complications does the nurse suspect?
- A. Infection.
- B. Disequilibrium syndrome.
- C. Air embolus.
- D. Infection.
Correct answer: C
Rationale: In this scenario, the client undergoing hemodialysis is experiencing symptoms like restlessness, a headache, and nausea. These symptoms are indicative of an air embolus, a serious complication that can occur during hemodialysis. Air embolus happens when air enters the bloodstream and can lead to symptoms like restlessness, a headache, and nausea. It is crucial for the nurse to suspect and address this complication promptly to prevent further harm to the client. Choices A and D (Infection) are less likely in this case, as the symptoms presented are more suggestive of an air embolus rather than an infection. Choice B (Disequilibrium syndrome) is also less likely as the symptoms described are not typical of this syndrome. Therefore, the correct answer is C: Air embolus.
