Nursing Elites

1. After a client with peripheral vascular disease undergoes a right femoral-popliteal bypass graft, their blood pressure drops from 124/80 to 94/62. What should the nurse assess first?

• A. IV fluid infusion.
• B. Pedal pulses.
• C. Nasal cannula oxygen flow rate.
• D. Capillary refill time.

Correct answer: B

Rationale: Assessing pedal pulses is crucial in this situation as it helps determine the adequacy of perfusion to the lower extremity following a bypass graft. A decrease in blood pressure postoperatively could indicate decreased perfusion, making the assessment of pedal pulses a priority to ensure proper circulation. Checking IV fluid infusion, nasal cannula oxygen flow rate, or capillary refill time are not the immediate priorities in this scenario and would not provide direct information about perfusion to the affected extremity.

2. A client in the emergency department is severely dehydrated and is prescribed 3 L of intravenous fluid over 6 hours. At what rate (mL/hr) should the nurse set the intravenous pump to infuse the fluids? (Record your answer using a whole number.)

• A. 500 mL/hr
• B. 400 mL/hr
• C. 550 mL/hr
• D. 600 mL/hr

Correct answer: A

Rationale: To calculate the rate of the intravenous pump, divide the total volume of fluid (3 L = 3000 mL) by the total time in hours (6 hours), which equals 500 mL/hr. The correct answer is A. Choice B (400 mL/hr) is incorrect as it would result in a slower infusion rate. Choice C (550 mL/hr) and Choice D (600 mL/hr) are incorrect as they would result in a faster infusion rate, exceeding the prescribed amount of fluid to be infused over 6 hours.

3. The nurse is obtaining the admission history for a client with suspected peptic ulcer disease (PUD). Which subjective data reported by the client supports this diagnosis?

• A. Frequent use of chewable and liquid antacids for indigestion
• B. Severe abdominal cramps and diarrhea after eating spicy foods
• C. Upper mid-abdominal gnawing and burning pain
• D. Marked weight loss and appetite over the last 3 to 4 months

Correct answer: C

Rationale: The correct answer is C: 'Upper mid-abdominal gnawing and burning pain.' This symptom is a classic presentation of peptic ulcer disease. Antacids (choice A) may provide relief but do not confirm the diagnosis. Severe abdominal cramps and diarrhea (choice B) are more suggestive of other conditions like irritable bowel syndrome. Weight loss and appetite changes (choice D) are non-specific and could be related to various health issues.

4. A client is experiencing diarrhea. For which acid-base disorder should the nurse assess the client?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: When a client experiences diarrhea, the loss of bicarbonate-rich fluids from the body leads to a decrease in the bicarbonate levels in the blood, resulting in metabolic acidosis. Metabolic alkalosis (choice B) is characterized by an increase in bicarbonate levels, which is not typically associated with diarrhea. Respiratory acidosis (choice C) is caused by retention of carbon dioxide, while respiratory alkalosis (choice D) results from excessive exhalation of carbon dioxide, neither of which are directly related to diarrhea. Therefore, the correct answer is metabolic acidosis (choice A) in the context of diarrhea.

5. When a patient is receiving high doses of a cephalosporin, which laboratory values will this patient's nurse monitor closely?

• A. Blood urea nitrogen (BUN), serum creatinine, and liver function tests
• B. Complete blood count and electrolytes
• C. Serum calcium and magnesium
• D. Serum glucose and lipids

Correct answer: A

Rationale: When a patient is receiving high doses of a cephalosporin, such as cefazolin, the nurse should closely monitor laboratory values that indicate renal and hepatic function. This includes checking the Blood Urea Nitrogen (BUN) and serum creatinine levels to assess kidney function. Additionally, monitoring liver function tests, such as AST, ALT, ALP, LDH, and bilirubin, is essential as cephalosporins can affect liver enzymes. Therefore, options B, C, and D are incorrect as they do not specifically address the parameters that are most pertinent when administering high doses of cephalosporins.
