Question 1 of 5
A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 mL via intermittent IV bolus over 30 minutes. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 50
Rationale:
To calculate the IV infusion rate in drops per minute (gtt/min), we can use the formula: (Volume to be infused in mL x Drop factor) / Time in minutes. In this case, the volume to be infused is 100 mL, drop factor is 15 gtt/mL, and the time is 30 minutes. Plugging these values into the formula: (100 mL x 15 gtt/mL) / 30 minutes = 1500 gtt / 30 minutes = 50 gtt/min.
Therefore, the correct answer is 50 gtt/min. This rate ensures the cefazolin is administered over the desired 30-minute timeframe. Other choices are incorrect because they do not align with the calculated rate based on the given parameters.
Question 2 of 5
A nurse is caring for a client who is receiving diazepam for moderate (conscious) sedation. Which of the following actions should the nurse take to assess for an adverse reaction to the medication?
Correct Answer: A
Rationale: The correct answer is A: Monitor the client's oxygen saturation. When a client is receiving diazepam for sedation, respiratory depression is a potential adverse reaction. Monitoring oxygen saturation helps assess the client's respiratory status. This is crucial as diazepam can suppress the respiratory drive, leading to hypoxemia. Monitoring for seizure activity (
B) is not directly related to diazepam administration for sedation. Checking urinary output (
C) and auscultating bowel sounds (
D) are not relevant in assessing adverse reactions to diazepam for sedation.
Question 3 of 5
A nurse is assessing a client who has received oxycodone. The nurse notes that the client's respiratory rate is 8/min. The nurse should identify that which of the following is the pathophysiology for the client's respiratory rate?
Correct Answer: D
Rationale: The correct answer is D: Oxycodone causes central nervous system depression. Oxycodone is an opioid that acts on the central nervous system, specifically the brainstem, to depress the respiratory center. This results in decreased respiratory rate. Options A, B, and C are incorrect because oxycodone does not directly affect cranial arteries, sodium channels, or prostaglandin synthesis in a way that would lead to respiratory depression. Option E is blank, but it would likely be incorrect as well since the correct answer is related to the central nervous system.
Question 4 of 5
A nurse is preparing to mix short-acting insulin with NPH insulin from two vials. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct action is to inject air into the short-acting insulin vial before withdrawing it. This is because it prevents the formation of a vacuum in the vial, making it easier to withdraw the correct dose. Ensuring the NPH insulin is drawn first (
B) is incorrect because it may lead to contamination of one insulin with the other. Using two separate syringes (
C) is unnecessary and increases the risk of dosing errors. Administering the insulin within 20 minutes (
D) is not relevant to the mixing process.
Question 5 of 5
A nurse is assessing a client who has septic shock and is receiving dopamine by continuous IV infusion. Which of the following findings indicates that the nurse should increase the rate of infusion?
Correct Answer: B
Rationale: The correct answer is B: Hypotension. In septic shock, dopamine is used to increase blood pressure. Hypotension indicates that the current dosage is not effectively managing the client's blood pressure, necessitating an increase in the infusion rate to achieve the desired therapeutic effect. Headache (choice
A) is a common side effect of dopamine but does not directly correlate with the need for a dosage increase. Chest pain (choice
C) may indicate other issues but does not specifically warrant a change in dopamine infusion rate. Extravasation (choice
D) refers to the leakage of IV fluid into the surrounding tissue and requires immediate attention but is not directly related to adjusting the infusion rate of dopamine.
