1. The client admitted with peripheral vascular disease (PVD) asks the nurse why her legs hurt when she walks. The nurse bases a response on the knowledge that the main characteristic of PVD is:
- A. Decreased blood flow.
- B. Increased blood flow.
- C. Slow blood flow.
- D. Thrombus formation.
Correct answer: A
Rationale: The correct answer is A: 'Decreased blood flow.' In peripheral vascular disease (PVD), there is a narrowing or blockage of blood vessels, leading to reduced blood flow to the extremities. This decreased blood flow results in inadequate oxygen supply to the muscles, causing pain, especially during physical activity when oxygen demand increases. Choice B, 'Increased blood flow,' is incorrect because PVD is characterized by impaired blood circulation rather than increased flow. Choice C, 'Slow blood flow,' is not precise as PVD involves a more significant reduction in blood flow. Choice D, 'Thrombus formation,' is related to the formation of blood clots within vessels, which can be a complication of PVD but is not its main characteristic.
2. The healthcare provider is caring for a client with a urinary tract infection. Which finding requires immediate intervention?
- A. Dysuria.
- B. Hematuria.
- C. Fever.
- D. Urinary frequency.
Correct answer: C
Rationale: Fever can indicate a severe infection, such as pyelonephritis, in a client with a urinary tract infection and requires immediate intervention. Hematuria and dysuria are common symptoms of a urinary tract infection but may not always require immediate intervention unless severe. Urinary frequency is also a common symptom and does not indicate the severity of the infection as fever does.
3. In a patient with diabetes mellitus, which of the following is a sign of hypoglycemia?
- A. Polydipsia.
- B. Polyuria.
- C. Sweating.
- D. Dry skin.
Correct answer: C
Rationale: Sweating is a common sign of hypoglycemia in diabetic patients. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, which can cause sweating as a response to the perceived danger. Polydipsia (excessive thirst) and polyuria (excessive urination) are actually more commonly associated with hyperglycemia, not hypoglycemia. Dry skin is not typically a sign of hypoglycemia.
4. When introducing solid foods to an infant, what food should be recommended to be introduced first?
- A. Strained fruits
- B. Pureed meats
- C. Cooked egg whites
- D. Iron-fortified cereal
Correct answer: D
Rationale: When introducing solid foods to infants, iron-fortified cereal is usually recommended as the first food due to its high nutritional value and the importance of iron for the baby's development. Strained fruits (choice A) are often introduced later due to their higher sugar content. Pureed meats (choice B) and cooked egg whites (choice C) are usually introduced after iron-fortified cereal to provide additional sources of protein and other nutrients.
5. The nurse is caring for a patient who is receiving oral potassium chloride supplements. The nurse notes that the patient has a heart rate of 120 beats per minute and has had a urine output of 200 mL in the past 12 hours. The patient reports abdominal cramping. Which action will the nurse take?
- A. Contact the provider to request an order for serum electrolytes.
- B. Encourage the patient to consume less fluids.
- C. Report symptoms of hyperkalemia to the provider.
- D. Request an order to increase the patient’s potassium dose.
Correct answer: A
Rationale: Oliguria, tachycardia, and abdominal cramping are signs of hyperkalemia, so the nurse should request an order for serum electrolytes to assess the patient's potassium levels. Encouraging the patient to consume less fluids would not address the underlying issue of potential hyperkalemia. Reporting symptoms of hyperkalemia to the provider is not as proactive as directly requesting serum electrolytes. Increasing the patient's potassium dose would worsen hyperkalemia, which is already suspected based on the symptoms presented.
