Nursing Elites

1. A client has an elevated AST 24 hours following chest pain and shortness of breath. This is suggestive of which of the following?

• A. Gallbladder disease
• B. Liver disease
• C. Myocardial infarction
• D. Skeletal muscle injury

Correct answer: C

Rationale: An elevated AST level following chest pain and shortness of breath is suggestive of myocardial infarction. AST is released from damaged heart muscle cells during a heart attack, indicating cardiac involvement. This enzyme is not specific to liver disease, gallbladder disease, or skeletal muscle injury in this clinical context.

2. A client is to receive cimetidine (Tagamet) 300 mg q6h IVP. The preparation arrives from the pharmacy diluted in 50 ml of 0.9% NaCl. The nurse plans to administer the IVPB dose over 20 minutes. For how many ml/hr should the infusion pump be set to deliver the secondary infusion?

• A. 75 ml/hr
• B. 150 ml/hr
• C. 225 ml/hr
• D. 300 ml/hr

Correct answer: B

Rationale: To calculate the infusion rate, set up a ratio proportion problem: 50 ml/20 min = x ml/60 min. Cross multiply to solve: 50 × 60 / 20 = 150 ml/hr. Therefore, the infusion pump should be set to deliver the secondary infusion at a rate of 150 ml/hr. Option A, 75 ml/hr, is incorrect because it does not account for the correct calculation. Option C, 225 ml/hr, is incorrect as it is too high a rate based on the calculation. Option D, 300 ml/hr, is also incorrect as it does not align with the correct calculation for the infusion rate.

3. Which assessment data indicates the need for the nurse to include the problem 'Risk for falls' in a client’s plan of care?

• A. Recent serum hemoglobin level of 16 g/dL
• B. Opioid analgesic received one hour ago
• C. Stooped posture with an unsteady gait
• D. Expressed feelings of depression

Correct answer: B

Rationale: The correct answer is B. The administration of opioid analgesics can impair balance and increase the risk of falls, justifying the inclusion of 'Risk for falls' in the client’s care plan. Choice A, a recent serum hemoglobin level of 16 g/dL, is not directly related to the risk of falls. Choice C, stooped posture with an unsteady gait, may indicate a risk for falls, but the direct influence of opioid analgesics on balance is more immediate. Choice D, expressed feelings of depression, while important, is not a direct indicator of the immediate risk for falls associated with opioid analgesic use.

4. A client with frequent urinary tract infections (UTIs) asks the nurse about drinking juice daily to prevent future UTIs. Which response is best for the nurse to provide?

• A. Orange juice has vitamin C, which deters bacterial growth.
• B. Apple juice is the most useful in acidifying the urine.
• C. Cranberry juice stops pathogens' adherence to the bladder.
• D. Grapefruit juice increases the absorption of most antibiotics.

Correct answer: C

Rationale: Cranberry juice is known for its ability to prevent urinary tract infections by reducing the adherence of Escherichia coli bacteria to the cells within the bladder. This property helps in maintaining urinary tract health and preventing recurrent UTIs. Choices A, B, and D are incorrect because while vitamin C in orange juice may have some benefits, it is not specifically known for deterring bacterial growth in the urinary tract. Apple juice does not significantly impact urine acidity, and grapefruit juice does not enhance antibiotic absorption, making them less effective choices for preventing UTIs compared to cranberry juice.

5. A client with a diagnosis of anemia is receiving epoetin alfa (Epogen). Which laboratory test should the nurse monitor to evaluate the effectiveness of this medication?

• A. White blood cell count.
• B. Hemoglobin and hematocrit.
• C. Platelet count.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: To evaluate the effectiveness of epoetin alfa (Epogen) in treating anemia, the nurse should monitor hemoglobin and hematocrit levels. These values indicate the oxygen-carrying capacity of the blood, which directly relates to the treatment of anemia. White blood cell count (A), platelet count (C), and blood urea nitrogen (BUN) and creatinine (D) are not specific indicators of the effectiveness of epoetin alfa in treating anemia.
