Nursing Elites

1. Following a gunshot wound to the abdomen, a young adult male had an emergency bowel resection and received multiple blood products. His current blood pressure is 78/52 mm Hg, and he is being mechanically ventilated. His oxygen saturation is 87%. Laboratory values indicate hemoglobin of 7 g/dL, platelets of 20,000/mm³, and white blood cells of 2,000/mm³. Which intervention should the nurse implement first?

• A. Transfuse packed red blood cells.
• B. Obtain blood and sputum cultures.
• C. Infuse 1000 ml of normal saline.
• D. Titrate oxygen to keep O2 saturation above 90%.

Correct answer: A

Rationale: The correct answer is to transfuse packed red blood cells first. The client's low hemoglobin level of 7 g/dL indicates severe anemia, which requires immediate transfusion to increase oxygen-carrying capacity. While obtaining blood and sputum cultures (Choice B) is important to identify potential infections, addressing the critical issue of anemia takes precedence. Infusing normal saline (Choice C) may help with volume status but does not address the primary concern of low hemoglobin. Titration of oxygen (Choice D) is crucial, but transfusion to improve oxygen-carrying capacity should be the priority in this scenario.

2. A client with severe COPD is receiving oxygen therapy at 2 liters per minute via nasal cannula. The client's oxygen saturation level drops to 88% during ambulation. What action should the nurse take first?

• A. Increase the oxygen flow rate to 4 liters per minute.
• B. Instruct the client to rest until the oxygen saturation improves.
• C. Discontinue ambulation and return the client to bed.
• D. Encourage the client to breathe more deeply.

Correct answer: C

Rationale: In this scenario, the client's oxygen saturation level dropping during ambulation indicates an inadequate oxygen supply. The first action the nurse should take is to discontinue ambulation and return the client to bed. This helps stabilize the oxygen level by reducing the oxygen demand placed on the client during physical activity. Increasing the oxygen flow rate without addressing the underlying issue of oxygen saturation dropping may not be effective. Instructing the client to rest is not enough to address the immediate need for stabilization of oxygen levels. Encouraging the client to breathe more deeply may not be sufficient to overcome the oxygen saturation drop caused by inadequate oxygen supply during ambulation.

3. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which laboratory value is most concerning?

• A. Serum glucose of 300 mg/dl
• B. Serum bicarbonate of 18 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Serum sodium of 135 mEq/L

Correct answer: C

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with DKA as it may indicate worsening hyperkalemia, requiring immediate intervention. Elevated serum potassium levels can lead to life-threatening cardiac arrhythmias. While elevated glucose and low bicarbonate are characteristic of DKA, hyperkalemia poses a higher immediate risk. Serum sodium within the normal range is not typically a primary concern in DKA.

4. A client who has just returned from surgery is shivering uncontrollably. What is the best action for the nurse to take?

• A. Offer the client a warm blanket
• B. Apply warm blankets and monitor the client's temperature
• C. Place a warm blanket in the client's bed before transferring the client from the stretcher
• D. Administer a prescribed muscle relaxant

Correct answer: B

Rationale: Applying warm blankets and monitoring the client's temperature is the best action to manage postoperative shivering. Shivering after surgery can be a common response due to factors like exposure to cold, pain, or anesthesia effects. Providing warmth through blankets can help regulate the client's body temperature and alleviate shivering. Monitoring the client's temperature is essential to ensure it returns to a normal range. Option A is not as comprehensive as option B, which includes both providing warmth and monitoring the client. Option C is incorrect as it focuses on preparing the bed rather than addressing the client's immediate need for warmth. Option D is not appropriate without further assessment or prescription for a muscle relaxant to address shivering.

5. In caring for a client receiving the aminoglycoside antibiotic gentamicin, what diagnostic test should the nurse prioritize monitoring?

• A. Urinalysis
• B. Serum creatinine
• C. Serum osmolarity
• D. Liver enzymes

Correct answer: B

Rationale: The correct answer is B: Serum creatinine. Aminoglycosides, such as gentamicin, are known to cause nephrotoxicity, which can lead to kidney damage. Monitoring serum creatinine levels is crucial in assessing renal function and detecting any potential kidney problems early. Choices A, C, and D are incorrect because urinalysis primarily assesses urine composition, serum osmolarity measures the concentration of solutes in the blood, and liver enzymes are not directly impacted by aminoglycoside antibiotics like gentamicin.
