Nursing Elites

1. The healthcare professional prepares a 1,000 ml IV of 5% dextrose and water to be infused over 8 hours. The infusion set delivers 10 drops per milliliter. The healthcare professional should regulate the IV to administer approximately how many drops per minute?

• A. 80
• B. 8
• C. 21
• D. 25

Correct answer: C

Rationale: To calculate the drops per minute for the IV infusion, first determine the total drops to be infused over 8 hours. 1,000 ml to be infused over 8 hours means 125 ml per hour (1000 ml / 8 hours = 125 ml/hr). Since the infusion set delivers 10 drops per ml, 125 ml/hr x 10 drops/ml = 1250 drops/hr. To find drops per minute, divide the drops per hour by 60 (minutes in an hour): 1250 drops/hr / 60 minutes = 20.83 drops/minute, which rounds up to 21 drops per minute (Option C). This rate ensures the correct infusion rate over 8 hours. Choices A, B, and D are incorrect calculations and do not provide the appropriate infusion rate needed to administer the IV over the specified time period.

2. A client has been on bed rest for several weeks. Which finding should the nurse identify as the priority during assessment?

• A. Musculoskeletal weakness
• B. Loss of appetite
• C. Increased heart rate during physical activity
• D. Left lower extremity tenderness

Correct answer: D

Rationale: The nurse should prioritize assessing left lower extremity tenderness as it could indicate deep vein thrombosis, a serious condition that requires immediate attention. Musculoskeletal weakness, loss of appetite, and increased heart rate during physical activity are important but not as critical as a potential thrombotic event that could lead to life-threatening complications. Deep vein thrombosis is a common risk for individuals on prolonged bed rest due to reduced mobility and blood stasis.

3. Which anatomical location is associated with the deep tendon reflex known as the patellar reflex?

• A. Knee picture
• B. Ankle picture
• C. Elbow picture
• D. Wrist picture

Correct answer: A

Rationale: The patellar reflex, also called the knee-jerk reflex, is elicited by tapping the patellar tendon just below the patella. This reflex involves the quadriceps muscle and the femoral nerve. The correct answer is 'A: Knee picture' because the patellar reflex is associated with the knee joint. Choices B, C, and D are incorrect as they do not correspond to the anatomical location involved in the patellar reflex.

4. A healthcare professional is preparing to administer lactated Ringer's (LR) IV 100 mL over 15 min. 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. 400 mL/hr
• B. 200 mL/hr
• C. 300 mL/hr
• D. 250 mL/hr

Correct answer: A

Rationale: To administer 100 mL over 15 min, the IV pump should be set to deliver 400 mL/hr. This calculation is based on the concept that if 100 mL is given in 15 minutes, to find out how many milliliters are given in an hour, you would multiply by 4 (since 15 minutes is a quarter of an hour). Therefore, 100 mL x 4 = 400 mL per hour. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate required to administer 100 mL over 15 minutes.

5. 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.
