1. Which electrolyte imbalance is most likely to be seen in a patient with chronic kidney disease?
- A. Hypernatremia.
- B. Hyperkalemia.
- C. Hypocalcemia.
- D. Hypokalemia.
Correct answer: B
Rationale: In chronic kidney disease, hyperkalemia is the most common electrolyte imbalance due to the kidneys' reduced ability to excrete potassium. This impaired kidney function leads to potassium retention in the body, resulting in elevated serum potassium levels. Hypernatremia (increased sodium levels) is less likely in chronic kidney disease as the kidneys typically still function to regulate sodium levels. Hypocalcemia (low calcium levels) is not a prominent electrolyte imbalance in chronic kidney disease unless there are additional factors involved. Hypokalemia (low potassium levels) is less common in chronic kidney disease, as the primary issue is usually potassium retention rather than deficiency.
2. After placing a stethoscope as seen in the picture, the nurse auscultates S1 and S2 heart sounds. To determine if an S3 heart sound is present, what action should the nurse take first?
- A. Slide the stethoscope across the sternum.
- B. Move the stethoscope to the mitral site.
- C. Listen with the bell at the same location.
- D. Observe the cardiac telemetry monitor.
Correct answer: C
Rationale: The nurse uses the bell of the stethoscope to hear low-pitched sounds such as S3 and S4. To determine if an S3 heart sound is present, the nurse should listen at the same location using the bell first. This allows for the accurate identification of low-pitched sounds. Moving the stethoscope across the sternum (Choice A) or to the mitral site (Choice B) would not be the initial actions to assess for an S3 heart sound. Observing the cardiac telemetry monitor (Choice D) is not relevant for assessing S3 heart sounds, as it does not provide direct auscultation of heart sounds.
3. Nurse Perry is caring for a female client with type 1 diabetes mellitus who exhibits confusion, light-headedness, and aberrant behavior. The client is still conscious. The nurse should first administer:
- A. I.M. or subcutaneous glucagon.
- B. I.V. bolus of dextrose 50%.
- C. 15 to 20 g of a fast-acting carbohydrate such as orange juice.
- D. 10 U of fast-acting insulin.
Correct answer: C
Rationale: For a conscious client with hypoglycemia, the initial treatment should involve administering 15 to 20 g of a fast-acting carbohydrate, such as orange juice. This helps rapidly raise the client's blood glucose levels. Choices A and D are incorrect as administering glucagon or fast-acting insulin is not the first-line treatment for hypoglycemia in a conscious client. Choice B, an I.V. bolus of dextrose 50%, is a more invasive and aggressive intervention that is not typically indicated for a conscious client with hypoglycemia.
4. A client is scheduled for a colonoscopy and has been prescribed a bowel preparation. What is the most important instruction for the nurse to provide?
- A. Eat a low-fiber diet the day before the procedure
- B. Drink clear liquids 24 hours before the procedure
- C. Take the entire bowel preparation as directed
- D. Avoid all solid foods 12 hours before the procedure
Correct answer: C
Rationale: The most important instruction for the nurse to provide to a client scheduled for a colonoscopy and prescribed a bowel preparation is to take the entire bowel preparation as directed. Completing the entire bowel preparation as prescribed is crucial to ensure the colon is properly cleansed for the colonoscopy. Incomplete bowel prep can interfere with the visualization of the colon, leading to inaccurate results. Choices A, B, and D are important but not as crucial as ensuring the complete intake of the bowel preparation for an effective procedure.
5. The client is receiving dietary instructions for hypoparathyroidism. Which of the following dietary recommendations is appropriate?
- A. Increase intake of dairy products and green leafy vegetables
- B. Avoid foods high in calcium
- C. Consume a high-sodium diet
- D. Limit fluid intake to prevent fluid overload
Correct answer: A
Rationale: For clients with hypoparathyroidism, the appropriate dietary recommendation is to increase intake of calcium-rich foods like dairy products and green leafy vegetables to help manage hypocalcemia. This is because hypoparathyroidism leads to low levels of calcium in the blood, so increasing calcium intake through diet is essential. Choices B, C, and D are incorrect. Avoiding foods high in calcium (choice B) would exacerbate the hypocalcemia. Consuming a high-sodium diet (choice C) is not necessary for managing hypoparathyroidism. Limiting fluid intake (choice D) is not directly related to the dietary management of hypoparathyroidism.
