1. A healthcare professional is assessing a client with severe dehydration. Which finding indicates a need for immediate intervention?
- A. Heart rate of 110 beats per minute.
- B. Blood pressure of 90/60 mm Hg.
- C. Urine output of 20 ml/hour.
- D. Dry mucous membranes.
Correct answer: C
Rationale: A urine output of 20 ml/hour indicates severe dehydration and impaired renal function. This finding suggests a critical state where the kidneys are conserving water, leading to reduced urine output. Immediate intervention is required to restore fluid balance and prevent further complications associated with severe dehydration. Choice A, a heart rate of 110 beats per minute, may indicate dehydration but is not as severe as the critically low urine output. Choice B, a blood pressure of 90/60 mm Hg, can be seen in dehydration but is not as concerning as the extremely low urine output. Choice D, dry mucous membranes, is a common sign of dehydration but does not require immediate intervention compared to the severely reduced urine output.
2. Why is a client with ascites scheduled for a paracentesis procedure?
- A. To diagnose liver disease
- B. To relieve abdominal pressure
- C. To assess kidney function
- D. To reduce blood pressure
Correct answer: B
Rationale: The correct answer is B: "To relieve abdominal pressure." Paracentesis is performed to drain accumulated fluid in the peritoneal cavity, providing symptomatic relief for clients with ascites. Choice A is incorrect because paracentesis is not a diagnostic procedure for liver disease. Choice C is incorrect as assessing kidney function would typically involve different procedures. Choice D is incorrect as paracentesis does not directly impact blood pressure.
3. A patient with type 2 diabetes is prescribed metformin. What instruction should the nurse provide regarding this medication?
- A. Take the medication on an empty stomach.
- B. Monitor for signs of hypoglycemia.
- C. Take the medication with meals.
- D. Increase intake of simple carbohydrates.
Correct answer: C
Rationale: The correct instruction for a patient prescribed metformin is to take the medication with meals. This helps reduce gastrointestinal side effects commonly associated with metformin. Patients should also be educated about the signs of lactic acidosis, a rare but serious side effect associated with metformin use.
4. A client with type 1 diabetes mellitus is admitted with hyperglycemia. Which laboratory result requires the most immediate intervention?
- A. Serum glucose of 350 mg/dL.
- B. Serum potassium of 2.8 mEq/L.
- C. Serum sodium of 136 mEq/L.
- D. Serum bicarbonate of 20 mEq/L.
Correct answer: B
Rationale: A serum potassium level of 2.8 mEq/L is critically low and can cause cardiac arrhythmias, requiring immediate intervention. Hypokalemia is a life-threatening condition that needs prompt correction to prevent serious complications. High serum glucose levels (choice A) are a concern in diabetes but do not pose an immediate life-threatening risk compared to severe hypokalemia. Serum sodium (choice C) and serum bicarbonate levels (choice D) are within normal ranges and do not require immediate intervention.
5. A patient with heart failure is prescribed digoxin. What is the most important instruction the nurse should provide?
- A. Take an extra dose if you miss one.
- B. Avoid high-potassium foods.
- C. Report any visual disturbances.
- D. Stop taking the medication if your pulse is normal.
Correct answer: C
Rationale: The correct answer is C: 'Report any visual disturbances.' Patients taking digoxin should be instructed to report any visual disturbances, as this can be a sign of digoxin toxicity. Visual disturbances like changes in color vision, blurred vision, or seeing halos around lights can indicate an overdose of digoxin. Choices A, B, and D are incorrect. Instructing a patient to take an extra dose if they miss one can lead to overdose. Avoiding high-potassium foods is important for patients on potassium-sparing diuretics, not digoxin. Stopping the medication if the pulse is normal is incorrect, as the pulse rate alone is not an indicator of digoxin effectiveness or toxicity.
