1. A client has been admitted to the hospital with severe diarrhea. The nurse should monitor the client for which complication?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Hyperkalemia
- D. Hypercalcemia
Correct answer: A
Rationale: Severe diarrhea can lead to metabolic acidosis due to the loss of bicarbonate. When there is excessive loss of bicarbonate through diarrhea, the pH of the blood decreases, leading to metabolic acidosis. Metabolic alkalosis (Choice B) is not typically associated with severe diarrhea as it involves elevated pH and bicarbonate levels. Hyperkalemia (Choice C) is less likely with severe diarrhea as potassium is often lost along with fluids. Hypercalcemia (Choice D) is not a common complication of severe diarrhea; instead, hypocalcemia may occur due to malabsorption of calcium.
2. A client is receiving discharge teaching about a new prescription for digoxin (Lanoxin). Which statement by the client indicates a need for further teaching?
- A. I should avoid foods high in potassium while taking this medication.
- B. I will check my pulse before taking the medication.
- C. I should avoid taking antacids simultaneously with this medication.
- D. I will take the medication at the same time every day.
Correct answer: A
Rationale: The correct answer is A because clients taking digoxin should avoid foods high in potassium. High potassium levels can potentiate the effects of digoxin, leading to toxicity. Choices B, C, and D are correct statements regarding digoxin administration. Checking the pulse before taking the medication helps monitor for signs of digoxin toxicity. Avoiding taking antacids simultaneously prevents interactions that may reduce digoxin absorption. Taking the medication at the same time every day helps maintain a consistent blood level, ensuring optimal therapeutic effects.
3. During a neurologic examination, which assessment should a nurse perform to test a client's balance?
- A. Romberg test
- B. Heel-to-toe walk
- C. Snellen test
- D. Spinal accessory function
Correct answer: A
Rationale: The Romberg test is used to assess a client's balance by evaluating their ability to maintain a steady posture with eyes closed. The heel-to-toe walk is another assessment that tests balance by assessing gait and coordination. The Snellen test is used to assess visual acuity and is unrelated to balance. Testing spinal accessory function involves assessing the movement of the head and shoulders and is not directly related to balance assessment.
4. A 2-year-old child is brought to the health care provider's office with a chief complaint of mild diarrhea for 2 days. Nutritional counseling by the nurse should include which statement?
- A. Place the child on clear liquids and gelatin for 24 hours
- B. Continue with the regular diet and include oral rehydration fluids
- C. Give bananas, apples, rice, and toast as tolerated
- D. Place NPO for 24 hours, then rehydrate with milk and water
Correct answer: B
Rationale: In managing mild diarrhea in a 2-year-old child, it is important to maintain their regular diet and include oral rehydration fluids. Choice A of placing the child on clear liquids and gelatin for 24 hours may not provide adequate nutrition and can lead to further electrolyte imbalances. Choice C of giving bananas, apples, rice, and toast as tolerated is a part of the BRAT diet, which is not recommended as the primary approach anymore due to its limited nutritional value. Choice D of placing the child NPO for 24 hours and then rehydrating with milk and water is not appropriate as it can worsen dehydration and delay recovery. Therefore, the best option is to continue the child's regular diet while incorporating oral rehydration fluids to prevent dehydration and maintain nutritional status.
5. Which serum blood finding in diabetic ketoacidosis alerts the nurse that immediate action is required?
- A. pH below 7.3
- B. Potassium of 5.0
- C. HCT of 60
- D. PaO2 of 79%
Correct answer: C
Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.
