1. The nurse is teaching the main principles of hemodialysis to a client with chronic kidney disease. Which statement by the client indicates a need for further teaching by the nurse?
- A. My sodium level changes due to the movement from the blood into the dialysate.
- B. Dialysis works by the movement of wastes from higher to lower concentration.
- C. Extra fluid can be pulled from the blood by osmosis.
- D. The dialysate is similar to blood but without any toxins.
Correct answer: B
Rationale: The correct answer is B because dialysis works by the movement of solutes from an area of higher concentration to an area of lower concentration, which is known as diffusion. The other statements are accurate: A correctly describes the movement of sodium during hemodialysis, C explains the removal of excess fluid by osmosis, and D highlights the purpose of the dialysate in removing toxins from the blood.
2. What assessment is most important for the nurse to perform for a client with dehydration receiving IV fluids?
- A. Monitor the client’s electrolyte levels.
- B. Check the client’s urine output hourly.
- C. Assess the client’s skin turgor regularly.
- D. Monitor the client’s blood pressure every 15 minutes.
Correct answer: A
Rationale: The correct answer is to monitor the client’s electrolyte levels. When a client is receiving IV fluids for dehydration, it is crucial to assess their electrolyte levels regularly. Dehydration can lead to imbalances in electrolytes, especially sodium and potassium, which are essential for maintaining fluid balance and proper organ function. Checking urine output (Choice B) is important but not as critical as monitoring electrolyte levels. Assessing skin turgor (Choice C) is an indirect method of assessing dehydration but does not provide specific information about electrolyte imbalances. Monitoring blood pressure (Choice D) is important but not the most critical assessment in this scenario as electrolyte imbalances can have a more direct impact on the client's condition.
3. During photosynthesis in green plants, light energy is captured and used to convert all except which of the following into oxygen and energy-rich organic compounds?
- A. Minerals
- B. Water
- C. Carbon dioxide
- D. Metals
Correct answer: D
Rationale: During photosynthesis in green plants, light energy is utilized to convert water and carbon dioxide into oxygen and energy-rich organic compounds like glucose. Minerals play a role in plant growth but are not directly converted during photosynthesis. Metals are not part of the photosynthesis process, making them the correct answer. Therefore, the correct choice is D. Choices A, B, and C are incorrect as minerals, water, and carbon dioxide are involved in the photosynthesis process.
4. The client, who is newly diagnosed with arteriosclerosis and is obese, is being educated by the nurse on reducing the risk of a heart attack or stroke. Which health promotion brochure should the nurse provide to this client?
- A. Monitoring Your Blood Pressure at Home
- B. Smoking Cessation as a Lifelong Commitment
- C. Decreasing Cholesterol Levels Through Diet
- D. Stress Management for a Healthier You
Correct answer: C
Rationale: The most significant risk factor contributing to arteriosclerosis is excess dietary fat, particularly saturated fat and cholesterol. Therefore, the most crucial brochure for the nurse to provide to the client focuses on decreasing cholesterol levels through diet to help reduce the risk of heart attack or stroke.
5. While assessing a client who is admitted with heart failure and pulmonary edema, the nurse identifies dependent peripheral edema, an irregular heart rate, and a persistent cough that produces pink blood-tinged sputum. After initiating continuous telemetry and positioning the client, which intervention should the nurse implement?
- A. Administer prescribed diuretics
- B. Prepare for intubation
- C. Notify the healthcare provider immediately
- D. Obtain sputum sample
Correct answer: D
Rationale: The client's cough producing pink, frothy sputum is indicative of pulmonary edema, which needs immediate treatment. Obtaining a sputum sample helps identify any infection that may be contributing to the pulmonary issues. Administering diuretics is essential in managing pulmonary edema but obtaining a sputum sample should take priority. Intubation may be necessary in severe cases but is not the initial intervention. Notifying the healthcare provider is important, but immediate action to diagnose and treat the condition is crucial.
