Nursing Elites

1. Why is it often necessary to draw a complete blood count and differential (CBC/differential) when a client is being treated with an antiepileptic drug (AED)?

• A. The hematocrit is adversely affected due to increased vascular volume.
• B. AEDs can lead to blood dyscrasia as a side effect.
• C. AEDs may cause aplastic anemia and megaloblastic anemia.
• D. Some AEDs induce white blood cell reduction.

Correct answer: B

Rationale: When a client is being treated with antiepileptic drugs (AEDs), it is essential to monitor for potential side effects on blood parameters. Some AEDs can lead to blood dyscrasia, which includes conditions like aplastic anemia and megaloblastic anemia. Therefore, drawing a complete blood count and differential helps in identifying these adverse effects early. Choices A, C, and D are incorrect because the primary concern when monitoring blood parameters in clients on AEDs is the risk of blood dyscrasia, not changes in hematocrit due to vascular volume, white blood cell reduction, or immune modulation.

2. The client with peripheral vascular disease is reviewing self-care measures. Which of the following statements indicates proper self-care measures?

• A. "I like to soak my feet in the hot tub every day."?
• B. "I walk to the mailbox in my bare feet."?
• C. "I stopped smoking and only use chewing tobacco."?
• D. "I have my wife examine the soles of my feet each day."?

Correct answer: D

Rationale: The correct answer is, "I have my wife examine the soles of my feet each day."? Clients with peripheral vascular disease should examine their feet daily for any signs of redness, dryness, or cuts. If the client is unable to do this themselves due to decreased sensation in their feet, a caregiver or family member should assist. Soaking feet in a hot tub should be avoided as the client may not be able to sense if the water is too hot, potentially causing burns. Walking barefoot can lead to injuries, so wearing shoes or slippers is recommended to minimize trauma. While quitting smoking is a positive step, using chewing tobacco can still constrict blood vessels, adversely affecting circulation in the extremities.

3. What is the most common cause of acute renal failure?

• A. Shock
• B. Nephrotoxic drugs
• C. Enlarged prostate
• D. Diabetes

Correct answer: A

Rationale: The most common cause of acute renal failure is shock. In cases of shock, such as hypovolemic shock where there is low blood volume, the kidneys receive inadequate blood flow leading to acute renal failure. This can result in the kidneys starting to die within 20 minutes of low pressure. While nephrotoxic drugs can also cause acute renal failure, shock is more commonly associated with this condition. An enlarged prostate can lead to urinary retention but is not the most common cause of acute renal failure. Diabetes, on the other hand, can cause chronic kidney disease over time but is not typically the primary cause of acute renal failure.

4. Signs of impaired breathing in infants and children include all of the following except:

• A. nasal flaring
• B. grunting
• C. seesaw breathing
• D. quivering lips

Correct answer: D

Rationale: Signs of impaired breathing in infants and children typically include nasal flaring, grunting, and seesaw breathing. Nasal flaring is the widening of the nostrils during breathing to help with air intake, grunting is a sound made during expiration to keep the airway open, and seesaw breathing is an abnormal pattern where the chest moves in while the abdomen moves out. Quivering lips are not a typical sign of impaired breathing in infants and children, making it the correct answer. Nasal flaring, grunting, and seesaw breathing are all signs indicating the need for immediate medical attention due to potential respiratory distress.

5. Which medication should the nurse withhold if the client's blood pressure is 88/50?

• A. Rosuvastatin (Crestor)
• B. Enalapril (Vasotec)
• C. Digoxin (Lanoxin)
• D. Clopidogrel (Plavix)

Correct answer: B

Rationale: Enalapril (Vasotec) is the correct answer. It is an angiotensin-converting enzyme (ACE) inhibitor that can further lower blood pressure. Given that the client's blood pressure is already low at 88/50, administering Enalapril could exacerbate hypotension and compromise perfusion to vital organs. Rosuvastatin (Crestor), Digoxin (Lanoxin), and Clopidogrel (Plavix) are not contraindicated in the context of low blood pressure and may be administered safely.
