A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?
- A. 13 ml/hour
- B. 63 ml/hour
- C. 80 ml/hour
- D. 125 ml/hour
Correct Answer: B
Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.

The healthcare provider is preparing to administer a subcutaneous injection of heparin. Which site is most appropriate for the healthcare provider to use?
- A. Deltoid muscle
- B. Ventrogluteal site
- C. Abdomen
- D. Dorsogluteal site
Correct Answer: C
Rationale: The abdomen is the most appropriate site for administering subcutaneous heparin injections. The abdomen has a layer of subcutaneous fat and a good blood supply, making it an ideal site for subcutaneous injections. Using the deltoid muscle for heparin injections is not appropriate as it is typically used for intramuscular injections. The ventrogluteal site is more suitable for intramuscular injections rather than subcutaneous injections. The dorsogluteal site is no longer recommended for injections due to the risk of injury to the sciatic nerve.
A healthcare professional is preparing to insert an IV catheter into a client's arm prior to initiating IV fluid therapy. Which of the following interventions should the healthcare professional implement to prevent infection?
- A. Thread the catheter up to the hub
- B. Use a sterile technique throughout the procedure
- C. Clean the insertion site with alcohol only
- D. Use gloves but not a mask during the procedure
Correct Answer: B
Rationale: Using a sterile technique throughout the procedure is essential to prevent infection when inserting an IV catheter. This includes maintaining aseptic conditions, using sterile equipment, and following proper hand hygiene practices. Choice A is incorrect because threading the catheter up to the hub does not specifically address infection prevention. Choice C is incorrect as cleaning the insertion site with alcohol only may not provide adequate disinfection, as it is essential to use an antiseptic solution to reduce microbial load. Choice D is incorrect as wearing gloves alone is not sufficient protection against infection; a mask should also be worn to prevent the spread of microorganisms through respiratory secretions.
A client with chronic kidney disease is being assessed. Which laboratory value would be most concerning?
- A. Serum creatinine of 3.0 mg/dL
- B. Blood urea nitrogen (BUN) of 45 mg/dL
- C. Serum potassium of 6.5 mEq/L
- D. Hemoglobin of 10 g/dL
Correct Answer: C
Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.
Following change-of-shift report on an orthopedic unit, which client should the nurse see first?
- A. 16-year-old who had an open reduction of a fractured wrist 10 hours ago
- B. 20-year-old in skeletal traction for 2 weeks since a motorcycle accident
- C. 72-year-old recovering from surgery after a hip replacement 2 hours ago
- D. 75-year-old who is in skin traction prior to planned hip pinning surgery
Correct Answer: C
Rationale: The 72-year-old recovering from surgery after a hip replacement 2 hours ago should be seen first due to the potential for immediate post-operative complications. This patient is in the immediate postoperative period and requires close monitoring for any signs of complications such as bleeding, infection, or impaired circulation. The other patients are relatively stable compared to the patient who just had surgery and therefore can wait for assessment and care without immediate risk. The 16-year-old had surgery ten hours ago, which is longer than the 72-year-old and is at a lower risk for immediate complications. The 20-year-old in skeletal traction for two weeks is stable in his current condition. The 75-year-old in skin traction before planned surgery does not require immediate attention as the surgery has not yet taken place.
A client is admitted to the hospital in the terminal stage of cancer. The nurse enters the client's room to administer medications and finds the client crying. The appropriate nursing action is to:
- A. Sit and hold the client's hand
- B. Ask why the client is crying
- C. Leave the room to give the client privacy
- D. Administer the medications and leave
Correct Answer: A
Rationale: In end-of-life care, providing comfort and emotional support is essential. Sitting with the client, holding their hand, and offering a compassionate presence can help the client feel supported during a difficult time. Asking why the client is crying may not always be necessary as the focus should be on providing comfort rather than probing for information. Leaving the room to provide privacy or just administering medications and leaving may neglect the client's emotional needs and miss an opportunity to provide holistic care.
