Nursing Elites

1. The client is being educated by the nurse on home blood glucose monitoring. Which of the following blood glucose measurements indicates hypoglycemia?

• A. 59 mg/dL (3.3 mmol/L)
• B. 75 mg/dL (4.2 mmol/L)
• C. 108 mg/dL (6 mmol/L)
• D. 119 mg/dL (6.6 mmol/L)

Correct answer: A

Rationale: A blood glucose level of 59 mg/dL (3.3 mmol/L) is considered hypoglycemia, which is an abnormally low blood sugar level. This level requires immediate attention as it can lead to symptoms such as confusion, shakiness, and even loss of consciousness if left untreated. Choices B, C, and D have blood glucose levels within the normal range or slightly higher, indicating euglycemia or normal blood sugar levels, and not hypoglycemia.

2. The nurse is caring for a patient whose serum sodium level is 140 mEq/L and serum potassium level is 5.4 mEq/L. The nurse will contact the patient’s provider to discuss an order for

• A. a low-potassium diet.
• B. intravenous sodium bicarbonate.
• C. Kayexalate and sorbitol.
• D. salt substitutes.

Correct answer: A

Rationale: In the scenario presented, the patient is experiencing mild hyperkalemia with a potassium level of 5.4 mEq/L. The appropriate intervention for mild hyperkalemia is a low-potassium diet to restrict potassium intake. This helps in managing and preventing further elevation of potassium levels. Intravenous sodium bicarbonate is not indicated as the patient's sodium level is normal at 140 mEq/L. Kayexalate, a cation-exchange resin, is typically used for severe hyperkalemia to promote potassium excretion. Salt substitutes, which often contain potassium chloride, should be avoided in patients with hyperkalemia as they can exacerbate the condition by increasing potassium levels further.

3. A nurse is assessing the chest tube drainage system of a postoperative client who has undergone a right upper lobectomy. The closed drainage system contains 300 mL of bloody drainage, and the nurse notes intermittent bubbling in the water seal chamber. One hour after the initial assessment, the nurse notes that the bubbling in the water seal chamber is now constant, and the client appears dyspneic. On the basis of these findings, the nurse should first assess:

• A. The client’s vital signs
• B. The amount of drainage
• C. The client’s lung sounds
• D. The chest tube connections

Correct answer: D

Rationale: The client’s dyspnea is most likely related to an air leak caused by a loose connection in the chest tube system. Checking the chest tube connections should be the initial action because correcting an air leak can quickly resolve the client's symptoms. If a leak is found and corrected, the dyspnea should improve. Assessing the client’s vital signs (Option A) is important, but addressing the potential cause of dyspnea takes precedence. Monitoring the amount of drainage (Option B) is necessary for assessing the client's overall condition, but in this case, the dyspnea is likely due to an air leak. Checking the client’s lung sounds (Option C) is essential for respiratory assessment, but addressing the air leak should be the immediate priority to ensure adequate lung expansion and oxygenation.

4. In a patient with anemia, which of the following is the primary symptom to assess?

• A. Fever.
• B. Chest pain.
• C. Shortness of breath.
• D. Muscle cramps.

Correct answer: C

Rationale: The correct answer is C: Shortness of breath. In a patient with anemia, the primary symptom to assess is shortness of breath. Anemia leads to a reduced oxygen-carrying capacity of the blood, resulting in tissues not receiving adequate oxygen. This can manifest as shortness of breath, especially during physical exertion. Fever (Choice A), chest pain (Choice B), and muscle cramps (Choice D) are not typically primary symptoms of anemia. Fever may suggest an infection, chest pain can be indicative of cardiac issues, and muscle cramps may be related to electrolyte imbalances or neuromuscular disorders.

5. The healthcare provider is unable to palpate the client's left pedal pulses. Which of the following actions should the healthcare provider take next?

• A. Auscultate the pulses with a stethoscope.
• B. Call the physician.
• C. Use a Doppler ultrasound device.
• D. Inspect the lower left extremity.

Correct answer: C

Rationale: When pedal pulses are not palpable, using a Doppler ultrasound device is the appropriate next step to locate the pulse. Auscultating the pulses with a stethoscope (Choice A) is used for assessing blood flow in arteries above the clavicle, not for pedal pulses. Calling the physician (Choice B) may be necessary at a later stage, but initially, using a Doppler ultrasound device to locate the pulse is more appropriate. Inspecting the lower left extremity (Choice D) can provide visual information but will not help in locating the pedal pulses, making it a less suitable option.
