Nokea
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.

The client is receiving discharge instructions for warfarin (Coumadin). Which statement by the client indicates a need for further teaching?
- A. I will avoid eating foods high in vitamin K.
- B. I will have my blood tested regularly to monitor my INR levels.
- C. I will take the medication at the same time every day.
- D. I will use a soft toothbrush to prevent bleeding gums.
Correct Answer: A
Rationale: The correct answer is A. Clients taking warfarin need to be consistent with their vitamin K intake to maintain a balance in blood clotting. Avoiding foods high in vitamin K is essential as they can interfere with the medication's effectiveness. Choices B, C, and D are all correct statements regarding warfarin therapy. Regular blood testing to monitor INR levels ensures the medication is working effectively, taking the medication at the same time daily maintains a consistent level in the bloodstream, and using a soft toothbrush helps prevent gum bleeding due to warfarin's anticoagulant effects.
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 client with herpes zoster asks the nurse about using complementary and alternative therapies for pain control. The nurse should inform the client that this condition is a contraindication for which of the following therapies?
- A. Biofeedback
- B. Aloe
- C. Feverfew
- D. Acupuncture
Correct Answer: D
Rationale: Acupuncture is contraindicated for clients with herpes zoster due to the risk of introducing an open portal on the skin, which can increase the risk of infection. This therapy involves inserting needles into specific points on the body, potentially causing skin trauma and providing a route for the virus to spread. Biofeedback, aloe, and feverfew are not contraindicated for clients with herpes zoster and can be considered for pain management in this condition. Biofeedback involves using electronic devices to help individuals learn to control physiological processes, aloe is a plant known for its skin-soothing properties, and feverfew is an herb that has been used for pain relief.
What intervention should be taken to minimize the risk for injury in a client with dementia?
- A. Use a bed exit alarm system.
- B. Place the client in restraints for safety.
- C. Ensure the client has frequent visitors to reduce isolation.
- D. Keep the client's room dark and quiet at night.
Correct Answer: A
Rationale: The correct intervention to minimize the risk for injury in a client with dementia is to use a bed exit alarm system. Bed exit alarms are effective tools to alert healthcare providers when a client attempts to get out of bed, helping prevent falls and injuries. Placing the client in restraints (Choice B) is not the preferred method as it can lead to physical and psychological harm, restrict mobility, and increase agitation. While social interaction is important for clients with dementia, ensuring frequent visitors (Choice C) is not directly related to preventing physical injuries. Keeping the client's room dark and quiet at night (Choice D) may be soothing for some clients but does not directly address the risk for injury associated with dementia.
A client requires an NG tube for stomach decompression. Which of the following actions should the nurse take when inserting the NG tube?
- A. Help the client take sips of water to promote insertion of the NG tube.
- B. Insert the tube without asking the client to swallow.
- C. Advance the tube continuously without pausing.
- D. Use a large-bore tube for insertion.
Correct Answer: A
Rationale: The correct action when inserting an NG tube is to help the client take sips of water. This helps facilitate the insertion of the tube by promoting swallowing and passage through the esophagus. Asking the client to swallow assists in guiding the tube into the stomach. Inserting the tube without asking the client to swallow may lead to incorrect placement or discomfort. Advancing the tube continuously without pausing can cause the tube to coil in the esophagus, leading to complications. Using a large-bore tube for insertion is unnecessary and may increase the risk of injury or discomfort for the client.
