Nursing Elites

1. A client is brought to the emergency department by a neighbor. The client is lethargic and has a fruity odor on the breath. The client’s arterial blood gas (ABG) results are pH 7.25, PCO2 34 mm Hg, PO2 86 mm Hg, HCO3 14 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

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

Correct answer: A

Rationale: The correct answer is 'Metabolic acidosis.' Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (HCO3 <22 mEq/L). In this case, the client's ABG results show a pH of 7.25 and an HCO3 level of 14 mEq/L, indicating metabolic acidosis. The PCO2 of 34 mm Hg is normal, ruling out respiratory acidosis or alkalosis. The PO2 of 86 mm Hg is also within the normal range and is not indicative of a respiratory problem. Therefore, the client is experiencing metabolic acidosis based on the ABG results provided.

2. An older adult client with a long history of chronic obstructive pulmonary disease (COPD) is admitted with progressive shortness of breath and a persistent cough. The client is anxious and complaining of a dry mouth. Which intervention should the nurse implement?

• A. Assist the client to an upright position
• B. Administer a prescribed sedative
• C. Apply a high-flow Venturi mask
• D. Encourage the client to drink water

Correct answer: A

Rationale: Assisting the client to an upright position is the most appropriate intervention in this scenario. An upright position helps optimize lung expansion and aids in improving ventilation, which can alleviate shortness of breath. This position also assists in reducing anxiety by providing a sense of control and comfort. Administering a sedative (Choice B) may further depress the respiratory drive in a client with COPD and should be avoided unless absolutely necessary. Applying a high-flow Venturi mask (Choice C) may be indicated later based on oxygenation needs, but the immediate focus should be on positioning. Encouraging the client to drink water (Choice D) may not directly address the respiratory distress and anxiety experienced by the client.

3. A client recovering from surgery has a large abdominal wound. Which of the following foods, high in vitamin C, should the nurse encourage the client to eat to promote wound healing?

• A. Steak
• B. Veal
• C. Cheese
• D. Oranges

Correct answer: D

Rationale: Oranges are a rich source of vitamin C, which is essential for wound healing due to its role in collagen synthesis. Citrus fruits like oranges, as well as other fruits and vegetables such as strawberries, kiwi, bell peppers, and broccoli, are high in vitamin C. Meats like steak and veal are not significant sources of vitamin C; they are primarily sources of protein. Cheese is not a good source of vitamin C but does provide calcium and protein.

4. A client receives a prescription for 1 liter of lactated Ringer's intravenously to be infused over 6 hours. How many mL/hr should the nurse program the infusion pump to deliver? (Enter numerical value only. If rounding is needed, round to the nearest whole number.)

• A. 167 mL/hr
• B. 200 mL/hr
• C. 83 mL/hr
• D. 111 mL/hr

Correct answer: A

Rationale: The correct infusion rate is 167 mL/hr. This is calculated by dividing the total volume (1000 mL) by the total time (6 hours), resulting in 166.67 mL/hr, which should be rounded to the nearest whole number as 167 mL/hr. This calculation ensures a steady infusion rate over the specified time frame. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation based on the volume and time provided in the prescription.

5. In a patient with chronic kidney disease, which of the following is a common electrolyte imbalance?

• A. Hyperkalemia.
• B. Hypokalemia.
• C. Hypernatremia.
• D. Hyponatremia.

Correct answer: A

Rationale: Hyperkalemia is a common electrolyte imbalance in chronic kidney disease. In chronic kidney disease, the kidneys' reduced function leads to the decreased excretion of potassium, resulting in elevated serum potassium levels. This can be dangerous as hyperkalemia can lead to life-threatening arrhythmias. Hypokalemia (Choice B) is less common in chronic kidney disease as the impaired kidneys tend to retain potassium. Hypernatremia (Choice C) is more commonly seen in conditions such as dehydration, not primarily in chronic kidney disease. Hyponatremia (Choice D) is also possible in chronic kidney disease but is less common compared to hyperkalemia.
