Nursing Elites

1. The nurse is caring for a client who has just returned from surgery with a urinary catheter in place. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs)?

• A. Irrigate the catheter daily
• B. Ensure the catheter bag is always below bladder level
• C. Change the catheter every 48 hours
• D. Administer prophylactic antibiotics

Correct answer: B

Rationale: The correct answer is to ensure the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Choice A, irrigating the catheter daily, is not recommended as it can introduce pathogens into the bladder. Changing the catheter too frequently (Choice C) can increase the risk of introducing pathogens. Administering prophylactic antibiotics (Choice D) is not the primary intervention for preventing CAUTIs and can lead to antibiotic resistance.

2. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

3. The nurse observes that a post-operative client's surgical wound has reddened edges and is oozing. What is the appropriate nursing action?

• A. Apply an antibiotic ointment
• B. Clean the wound with sterile saline
• C. Cover the wound with a sterile dressing
• D. Notify the surgeon immediately

Correct answer: D

Rationale: The correct action when a post-operative client's surgical wound has reddened edges and is oozing is to notify the surgeon immediately. Reddened, oozing wound edges can indicate an infection that requires prompt evaluation and intervention by the surgical team. Applying an antibiotic ointment (Choice A) without proper assessment and guidance can be inappropriate. Cleaning the wound with sterile saline (Choice B) and covering it with a sterile dressing (Choice C) may not address the potential infection adequately, and the client may require more specialized care that the surgeon can provide.

4. Which of the following are key parameters that produce blood pressure? (Select ONE that does not apply)

• A. Heart rate
• B. Stroke volume
• C. Peripheral resistance
• D. Neuroendocrine hormones

Correct answer: D

Rationale: Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.

5. During a routine prenatal visit, a nurse measures a client’s fundal height. The client is 26 weeks pregnant. What should the fundal height be?

• A. Approximately 26 cm
• B. Between 24 to 28 cm
• C. Above the umbilicus by two finger widths
• D. Below the xiphoid process

Correct answer: B

Rationale: The correct answer is B: Between 24 to 28 cm. Fundal height corresponds to the weeks of gestation, so at 26 weeks of pregnancy, the fundal height should range between 24 to 28 cm. This measurement is a quick way to assess fetal growth and amniotic fluid volume. Choice A is incorrect because fundal height may vary and not always match the exact weeks of pregnancy. Choice C, measuring above the umbilicus by two finger widths, is not a standard method for fundal height measurement. Choice D, below the xiphoid process, is too high and not relevant for assessing fundal height during pregnancy.
