1. How should fluid balance be assessed in a patient with heart failure?

A. Monitor daily weight
B. Monitor input and output
C. Check for edema
D. Monitor blood pressure

Correct answer: A

Rationale: In patients with heart failure, monitoring daily weight is the most accurate method for assessing fluid balance. Weight gain can indicate fluid retention, a common issue in heart failure patients. Monitoring input and output (B) is essential but may not always accurately reflect fluid balance. Checking for edema (C) is important as it can indicate fluid accumulation, but daily weight monitoring is more precise. Monitoring blood pressure (D) is important in heart failure management but does not directly assess fluid balance.

2. What is the appropriate intervention when a patient experiences a fall?

A. Assess for injuries
B. Call for help
C. Document the fall
D. Notify the healthcare provider

Correct answer: A

Rationale: The appropriate intervention when a patient experiences a fall is to assess for injuries. This immediate action helps in identifying any harm or complications resulting from the fall, allowing for timely intervention. Calling for help may be necessary after assessing the injuries, but the priority is to evaluate the patient's condition. Documenting the fall is important for record-keeping purposes but should come after ensuring the patient's safety. Notifying the healthcare provider can be done once the assessment has been completed and any necessary initial interventions have been initiated.

3. A nurse is caring for a client who has a pulmonary embolism. The nurse should identify the effectiveness of the treatment by assessing which of the following?

A. A chest x-ray reveals increased density in all lung fields
B. The client reports feeling less anxious
C. Diminished breath sounds are auscultated unilaterally
D. ABG results include pH 7.48, PaO2 77 mm Hg, and PaCO2 47 mm Hg

Correct answer: B

Rationale: The correct answer is B. Client-reported improvement in anxiety is an indication of effective treatment for pulmonary embolism. Choice A is incorrect as increased density in all lung fields on a chest x-ray may indicate complications or lack of improvement. Choice C is incorrect as diminished breath sounds auscultated unilaterally may suggest a localized lung issue and not necessarily reflect the effectiveness of treatment for a pulmonary embolism. Choice D is incorrect as the ABG results provided do not specifically indicate the effectiveness of treatment for a pulmonary embolism.

4. A nurse is reviewing the medical record of a client who has acute kidney injury. Which of the following findings should the nurse report to the provider?

A. Blood urea nitrogen (BUN) 15 mg/dL
B. Urine output of 45 mL/hr
C. Serum creatinine 3.5 mg/dL
D. Calcium 9 mg/dL

Correct answer: C

Rationale: The correct answer is C, 'Serum creatinine 3.5 mg/dL.' An elevated serum creatinine level indicates worsening kidney function and impaired renal clearance, which should be reported to the provider promptly. Choice A, 'Blood urea nitrogen (BUN) 15 mg/dL,' is within the normal range (7-20 mg/dL) and does not indicate acute kidney injury. Choice B, 'Urine output of 45 mL/hr,' is a low urine output but does not directly reflect kidney function decline. Choice D, 'Calcium 9 mg/dL,' is within the normal calcium range (8.5-10.5 mg/dL) and is not specifically indicative of acute kidney injury.

5. A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion. The client weighs 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

A. 6 mL/hr
B. 8 mL/hr
C. 12 mL/hr
D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, use the formula: (4 mcg/kg/min * 80 kg) / 800 mcg in 250 mL = 6 mL/hr. This calculation is based on the dose ordered (4 mcg/kg/min) multiplied by the patient's weight in kg (80 kg), divided by the concentration of the drug available (800 mcg in 250 mL) to be infused over 1 hour. Therefore, the correct answer is 6 mL/hr. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the provided information.
