1. What lab value should a healthcare provider monitor for a patient on warfarin therapy?

Correct answer: B

Rationale: The correct answer is B: PT/INR. When a patient is on warfarin therapy, healthcare providers monitor the PT/INR levels to evaluate the effectiveness of the treatment and assess the risk of bleeding. Monitoring potassium, sodium, or calcium levels is not directly related to warfarin therapy and would not provide the necessary information needed to manage the medication effectively.

2. A nurse is assessing a client who is experiencing a panic attack. Which of the following findings should the nurse expect?

Correct answer: D

Rationale: During a panic attack, the sympathetic nervous system is activated, leading to physiological responses such as dilated pupils. Bradycardia (slow heart rate) and hypotension (low blood pressure) are not typically associated with panic attacks. While chest pain can occur during a panic attack due to rapid breathing and muscle tension, dilated pupils are a more specific finding related to sympathetic activation in this context.

3. A healthcare provider is assessing a client who has pneumonia. Which of the following findings is the priority for the healthcare provider to report?

Correct answer: C

Rationale: A respiratory rate of 26/min is a sign of respiratory distress and should be reported promptly in a client with pneumonia. Rapid breathing can indicate inadequate oxygenation and ventilation, which may lead to respiratory failure. Crackles in the lung bases are common in pneumonia but may not be as urgent as a high respiratory rate. A blood pressure of 100/64 mm Hg is slightly low but may not be immediately life-threatening. A heart rate of 86/min is within the normal range for an adult and is not the most critical finding to report.

4. A client who is 14 weeks of gestation reports swelling of the face. What should the nurse do next?

Correct answer: B

Rationale: The correct answer is to report this finding to the provider immediately. Swelling of the face in pregnancy can be a sign of preeclampsia, a serious condition characterized by high blood pressure and signs of damage to another organ system, often the kidneys. Prompt reporting and intervention are crucial to prevent complications for both the client and the fetus. Administering an analgesic (choice A) is not appropriate for this situation as it does not address the underlying cause of the swelling. Administering an antiemetic (choice C) is used to treat nausea and vomiting, which are not the primary concerns associated with facial swelling in this scenario. Monitoring the client's vital signs (choice D) is important but should be done after reporting the finding to the provider to guide further assessment and management.

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?

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.
