1. A healthcare professional in a provider's office is reviewing the laboratory findings of a client who reports chills and aching joints. Which of the following findings should the healthcare professional identify as an indication that the client has an infection?
- A. WBC 15,000/mm³
- B. Hemoglobin 12 g/dL
- C. Platelet count 300,000/mm³
- D. Sodium 140 mEq/L
Correct answer: A
Rationale: An elevated white blood cell count (WBC 15,000/mm³) is a common indicator of infection as the body increases WBC production to fight off pathogens. In conditions like infections, inflammation, or stress, the WBC count can rise. The other options, hemoglobin, platelet count, and sodium levels, are not typically specific indicators of infection. Hemoglobin measures the oxygen-carrying capacity of red blood cells, platelet count assesses clotting ability, and sodium levels indicate electrolyte balance.
2. A client with a history of severe anxiety is scheduled for surgery. Which preoperative medication is the most appropriate for the LPN/LVN to administer to this client?
- A. Lorazepam (Ativan)
- B. Morphine sulfate
- C. Meperidine (Demerol)
- D. Promethazine (Phenergan)
Correct answer: A
Rationale: Lorazepam (Ativan) is the most appropriate preoperative medication for a client with severe anxiety. Lorazepam belongs to the benzodiazepine class and is commonly used to manage anxiety before surgical procedures due to its anxiolytic properties. Morphine sulfate and Meperidine (Demerol) are opioid analgesics, not typically indicated for preoperative anxiety. Promethazine (Phenergan) is an antihistamine used for nausea and vomiting, not anxiety management.
3. A healthcare professional is preparing to administer dextrose 5% in water (D5W) 1,000-mL IV to infuse over 10 hr. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)
- A. 100 mL/hr
- B. 150 mL/hr
- C. 75 mL/hr
- D. 50 mL/hr
Correct answer: A
Rationale: To infuse 1,000 mL over 10 hr, the IV pump should be set to deliver 100 mL/hr. This calculation is derived by dividing the total volume (1,000 mL) by the total time in hours (10 hr), resulting in the infusion rate of 100 mL/hr. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation for this scenario.
4. A client is 1-day postoperative and reports a pain level of 10 on a scale of 0 to 10. After reviewing the client’s medication administration record, which of the following medications should be administered?
- A. Meperidine 75 mg IM
- B. Fentanyl 50 mcg/hr transdermal patch
- C. Morphine 2 mg IV
- D. Oxycodone 10 mg PO
Correct answer: C
Rationale: Morphine IV is the most appropriate choice for severe postoperative pain due to its rapid onset and effectiveness. Meperidine is not preferred due to its potential side effects, and fentanyl patches are typically used for chronic pain, not acute postoperative pain. Oxycodone taken orally is not ideal for providing immediate relief in this situation.
5. When caring for a client prescribed a blood transfusion that parents refuse due to religious beliefs, what should the nurse do?
- A. Examine personal values about the issue.
- B. Proceed with the transfusion if medically necessary.
- C. Refer the issue to the ethics committee.
- D. Administer the blood transfusion without informing the parents.
Correct answer: A
Rationale: When faced with a situation where parents refuse a prescribed treatment due to religious beliefs, the nurse should first examine personal values, understand the client's or family’s beliefs, and respect their rights. Proceeding with the transfusion against the parents' wishes without exploring alternatives or understanding their perspective would violate the principle of respect for autonomy and could damage the therapeutic relationship. Referring the issue to the ethics committee should be considered if a resolution cannot be reached through open communication and negotiation with the family.
