1. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 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, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

2. A nurse is caring for a client who is receiving radiation therapy for breast cancer. Which of the following skin care instructions should the nurse provide?

A. Wear loose clothing over the radiation site.
B. Use scented lotions to moisturize the skin.
C. Apply ice packs to the radiation site for pain relief.
D. Expose the radiation site to sunlight for 20 minutes daily.

Correct answer: A

Rationale: The correct answer is A: Wear loose clothing over the radiation site. Clients receiving radiation therapy should wear loose clothing over the treatment area to prevent irritation and promote healing. Choice B is incorrect as scented lotions can irritate the skin during radiation therapy. Choice C is incorrect because ice packs should not be applied to the radiation site as they can exacerbate skin reactions. Choice D is incorrect as exposing the radiation site to sunlight can increase skin damage and should be avoided.

3. What is the priority nursing action for a patient with respiratory distress?

A. Administer oxygen
B. Reposition the patient
C. Administer bronchodilators
D. Provide chest physiotherapy

Correct answer: A

Rationale: The priority nursing action for a patient with respiratory distress is to administer oxygen. Oxygen therapy is crucial in improving oxygenation levels and relieving respiratory distress, making it the top priority intervention. Repositioning the patient, administering bronchodilators, or providing chest physiotherapy may be necessary interventions depending on the underlying cause, but ensuring adequate oxygen supply should take precedence in addressing respiratory distress.

4. What is the best initial action when a patient presents with confusion?

A. Administer IV fluids
B. Perform a neurological assessment
C. Administer electrolytes
D. Prepare for a CT scan

Correct answer: B

Rationale: When a patient presents with confusion, the best initial action is to perform a neurological assessment. This assessment helps in identifying potential causes of confusion such as neurological issues, infections, metabolic abnormalities, or medication side effects. Administering IV fluids (Choice A) may be necessary based on assessment findings, but it is not the first step. Administering electrolytes (Choice C) would also depend on the assessment results. Preparing for a CT scan (Choice D) may be indicated later in the diagnostic process but is not the initial action when a patient presents with confusion.

5. A nurse is assessing a client who is receiving morphine via a patient-controlled analgesia (PCA) pump. Which of the following findings should the nurse report to the provider?

A. Respiratory rate of 20/min
B. Oxygen saturation of 93%
C. Pain level of 2 on a scale of 0 to 10
D. Blood pressure of 110/70 mm Hg

Correct answer: D

Rationale: The correct answer is D because a blood pressure drop or other signs of morphine overdose should be reported, especially when using a PCA pump. Choices A, B, and C are within normal limits and do not indicate an immediate concern related to morphine administration.
