1. In hanging a parenteral IV fluid that is to be infused by gravity, rather than with an infusion pump, the nurse notes that the IV tubing is available in different drop factors. Which tubing is a microdrop set?
- A. 15 drops per milliliter
- B. 60 drops per milliliter
- C. 20 drops per milliliter
- D. 10 drops per milliliter
Correct answer: B
Rationale: A microdrop set delivers 60 drops per milliliter of IV fluid. This allows for a more precise control of the infusion rate. The correct choice is B because it provides the desired microdrop rate. Choices A, C, and D are incorrect. A delivers 15 drops per milliliter, which is a macrodrop set. C delivers 20 drops per milliliter, also a macrodrop set. D delivers 10 drops per milliliter, another macrodrop set. Therefore, the correct choice for a microdrop set is B.
2. During a screening on a patient with a recent cast on the left lower extremity, which of the following statements should the nurse be most concerned about?
- A. The patient reports, "I didn't keep my extremity elevated as the doctor asked me to."?
- B. The patient reports, "I have been having pain in my left calf."?
- C. The patient reports, "My left leg has really been itching."?
- D. The patient reports, "The arthritis in my wrists is flaring up when I put weight on my crutches."?
Correct answer: B
Rationale: The correct answer is B because pain in the left calf could indicate a potential neurovascular complication related to the casted extremity. It could suggest issues such as compartment syndrome or impaired circulation. Option A is not as concerning since not elevating the extremity may lead to swelling but is not an immediate concern. Option C indicates itching, which is common with casts and not as concerning as potential neurovascular issues. Option D, regarding arthritis in the wrists, is unrelated to the lower extremity issue being screened for.
3. The newborn nursery is filled to capacity. Which newborn should the nurse assess first?
- A. A three-hour-old just waking up after a period of sleep
- B. A two-day-old crying loudly
- C. A three-day-old two hours after circumcision
- D. A one-hour-old sucking his fist
Correct answer: A
Rationale: The most critical time for assessment in a newborn is during the second period of reactivity, which occurs approximately 3-5 hours after delivery. During this phase, newborns are more likely to gag on mucus and aspirate, making it crucial for the nurse to assess their respiratory status first. Choice A indicates a newborn in this critical phase, requiring immediate assessment for potential airway compromise or respiratory distress. Choices B, C, and D do not present an immediate need for assessment related to airway compromise or respiratory distress.
4. What is appropriate care for a client with neutropenia?
- A. Avoiding fresh fruits and vegetables.
- B. Having a private room.
- C. Wearing a mask when out of the room.
- D. Practicing routine hand washing.
Correct answer: C
Rationale: When a client has neutropenia, they have low white blood cell levels, which increases the risk of infections due to a weakened immune system. Wearing a mask when out of the room is crucial to reduce the risk of exposure to respiratory infections. Avoiding fresh fruits and vegetables is also necessary as they may contain harmful pathogens. Having a private room helps minimize exposure to pathogens and ensures that visitors are carefully screened for any signs of illness. Routine hand washing is essential to prevent the spread of infections in the healthcare setting, but the most direct measure to protect the client from potential infections is wearing a mask when out of the room.
5. A client has been taking a drug (Drug A) that is highly metabolized by the cytochrome P-450 system. He has been on this medication for 6 months. At this time, he is started on a second medication (Drug B) that is an inducer of the cytochrome P-450 system. You should monitor this client for:
- A. increased therapeutic effects of Drug A.
- B. increased adverse effects of Drug B.
- C. decreased therapeutic effects of Drug A.
- D. decreased therapeutic effects of Drug B.
Correct answer: C
Rationale: When a client is taking a drug (Drug A) metabolized by the cytochrome P-450 system and is then started on another drug (Drug B) that induces this system, the metabolism of Drug A is increased. This results in decreased therapeutic effects of Drug A as it is broken down more rapidly. Monitoring is required to address potential reduced efficacy. The therapeutic effect of Drug A is diminished, not enhanced. Inducing the cytochrome P-450 system does not directly increase the adverse effects of Drug B. Although Drug B is an inducer, its therapeutic effects are not decreased as it is not metabolized faster.
