1. A client with hypertension is prescribed a low-sodium diet. Which food should the client avoid?
- A. Fresh fruits
- B. Processed cheese
- C. Whole grain bread
- D. Fresh vegetables
Correct answer: B
Rationale: The correct answer is B: Processed cheese. Processed cheese is high in sodium and should be avoided in a low-sodium diet for clients with hypertension. Fresh fruits, whole grain bread, and fresh vegetables are generally low in sodium and can be part of a healthy diet for clients with hypertension.
2. A client with diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What do these symptoms indicate?
- A. Hypoglycemia
- B. Diabetic ketoacidosis (DKA)
- C. Hyperosmolar hyperglycemic state (HHS)
- D. Insulin shock
Correct answer: B
Rationale: Polyuria, polydipsia, and polyphagia are classic signs of diabetic ketoacidosis (DKA), which occurs due to a combination of hyperglycemia and ketone production. Hypoglycemia (Choice A) is characterized by low blood sugar levels, leading to symptoms like confusion, shakiness, and sweating, which are different from the symptoms described in the scenario. Hyperosmolar hyperglycemic state (HHS) (Choice C) typically presents with severe hyperglycemia, dehydration, and altered mental status, rather than the triad of symptoms mentioned. Insulin shock (Choice D) refers to a severe hypoglycemic reaction due to excessive insulin, manifesting with confusion, sweating, and rapid heartbeat, not the symptoms seen in the client with diabetes mellitus described in this scenario.
3. The nurse instructs the mother of a child with a ventricular septal defect that she can expect the child to become cyanotic when the child does what?
- A. Experiences an elevation in temperature.
- B. Sleeps on the left side.
- C. Cries vigorously.
- D. Eats.
Correct answer: C
Rationale: The correct answer is C: Cries vigorously. When the child cries vigorously, it increases the pressure in the right ventricle, allowing unoxygenated blood to enter the circulating volume, leading to cyanosis. This occurs due to the shunting of blood from the right side of the heart to the left side through the ventricular septal defect. Choices A, B, and D are incorrect because they do not directly impact the pressure in the right ventricle, which is crucial in causing cyanosis in this scenario.
4. Following surgical repair of the bladder, a female client is being discharged from the hospital to home with an indwelling urinary catheter. Which instruction is most important for the nurse to provide to this client?
- A. Avoid coiling the tubing and keep it free of kinks.
- B. Cleanse the perineal area with soap and water twice daily.
- C. Keep the drainage bag lower than the level of the bladder.
- D. Drink 1,000 ml of fluids daily to irrigate the catheter.
Correct answer: C
Rationale: The most crucial instruction for a client with an indwelling urinary catheter post-bladder surgery is to keep the drainage bag positioned lower than the level of the bladder. This positioning prevents backflow of urine into the bladder, reducing the risk of infection. Choice A, avoiding coiling the tubing and keeping it free of kinks, is important to maintain proper flow but not as critical as ensuring the drainage bag is lower than the bladder. Choice B, cleansing the perineal area, is essential for overall hygiene but not directly related to catheter care instructions. Choice D, drinking fluids to irrigate the catheter, is not recommended as it may increase the risk of infection and should be guided by healthcare providers based on specific needs.
5. A client is currently receiving an infusion labeled as 5% dextrose injection 500 ml with heparin sodium 25,000 units at 14 mL/hour per pump. A prescription is received to change the rate of the infusion to heparin 1,000 units/hour. How many ml/hour should the nurse program the infusion pump?
- A. 16 ml/hour.
- B. 18 ml/hour.
- C. 20 ml/hour.
- D. 22 ml/hour.
Correct answer: C
Rationale: To deliver 1,000 units/hour from a solution with 25,000 units in 500 ml, the rate should be set to 20 ml/hour. This is calculated by determining that the solution has 50 units/ml (25,000 units / 500 ml = 50 units/ml) and then dividing the required 1,000 units/hour by 50 units/ml, resulting in 20 ml/hour. Therefore, the nurse should program the infusion pump to deliver heparin at 20 ml/hour. Choices A, B, and D are incorrect as they do not align with the calculated rate of 20 ml/hour.
