Nursing Elites

1. A healthcare professional is reviewing the results of renal function testing in a client with renal calculi. Which finding indicates to the healthcare professional that the client’s blood urea nitrogen (BUN) level is within the normal range?

• A. 2 mg/dL
• B. 18 mg/dL
• C. 25 mg/dL
• D. 35 mg/dL

Correct answer: B

Rationale: The normal BUN ranges from 5 to 20 mg/dL. A BUN level of 18 mg/dL falls within this normal range. Values of 25 and 35 mg/dL are elevated, suggesting potential renal insufficiency. Choice A (2 mg/dL) is abnormally low and not indicative of a normal BUN level.

2. A client in the intensive care unit is started on continuous venovenous hemofiltration (CVVH). Which finding should prompt immediate action by the nurse?

• A. Blood pressure of 76/58 mm Hg
• B. Sodium level of 138 mEq/L
• C. Potassium level of 5.5 mEq/L
• D. Pulse rate of 90 beats/min

Correct answer: A

Rationale: The correct answer is A: Blood pressure of 76/58 mm Hg. In a client undergoing continuous venovenous hemofiltration (CVVH), hypotension can be a significant concern if replacement fluid does not adequately maintain blood pressure. The nurse should take immediate action to address hypotension to prevent further complications. The sodium level of 138 mEq/L is within normal range, and a potassium level of 5.5 mEq/L, while slightly elevated, may be expected in a patient with acute kidney injury. A pulse rate of 90 beats/min falls within the normal range and does not typically require immediate intervention in this context.

3. A client who has just undergone surgery suddenly experiences chest pain, dyspnea, and tachypnea. The nurse suspects that the client has a pulmonary embolism and immediately sets about:

• A. Preparing the client for a perfusion scan
• B. Attaching the client to a cardiac monitor
• C. Administering oxygen via nasal cannula
• D. Ensuring that the intravenous (IV) line is patent

Correct answer: C

Rationale: When a client who has just undergone surgery experiences sudden chest pain, dyspnea, and tachypnea, indicating possible pulmonary embolism, the immediate priority for the nurse is to administer oxygen via nasal cannula. This intervention aims to improve oxygenation and alleviate respiratory distress, which is crucial in the setting of a potential pulmonary embolism. Preparing the client for a perfusion scan is not the immediate priority as stabilizing the client's respiratory status comes first. While attaching the client to a cardiac monitor is important for monitoring, administering oxygen takes precedence in this situation. Ensuring IV line patency is relevant for overall client care but is not the priority when a client is experiencing respiratory distress requiring immediate intervention.

4. The adult client admitted to the post-anesthesia care unit (PACU) following abdominal surgery has a tympanic temperature of 94.6°F (34.8°C), a pulse rate of 88 beats/minute, a respiratory rate of 14 breaths/minute, and a blood pressure of 94/64 mmHg. Which action should the nurse implement?

• A. Take the client's temperature using another method.
• B. Raise the head of the bed to 60 to 90 degrees.
• C. Ask the client to cough and deep breathe.
• D. Check the blood pressure every five minutes for one hour.

Correct answer: A

Rationale: Taking the client's temperature using another method is the most appropriate action in this situation. A tympanic temperature of 94.6°F (34.8°C) is abnormally low and may not reflect the true core body temperature accurately. By using an alternative method, such as oral or rectal temperature measurement, the nurse can obtain a more reliable temperature reading. Raising the head of the bed (Choice B) is not directly related to addressing the low temperature. Asking the client to cough and deep breathe (Choice C) may be beneficial for respiratory function but does not address the temperature concern. Checking the blood pressure every five minutes for one hour (Choice D) is not the priority when the initial focus should be on accurate temperature assessment.

5. 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.
