Fundamentals of Nursing HESI
1. A nurse on a medical-surgical unit is washing her hands prior to assisting with a surgical procedure. Which of the following actions by the nurse demonstrates proper surgical hand-washing techniques?
- A. The nurse washes with her hands held higher than her elbows.
- B. The nurse uses a brush to scrub under her nails.
- C. The nurse washes for at least 30 seconds.
- D. The nurse uses alcohol-based hand rub only.
Correct answer: A
Rationale: Proper surgical hand-washing technique involves keeping the hands higher than the elbows to prevent contamination. Washing with hands held lower than the elbows can lead to potential contamination. Using a brush to scrub under the nails is not recommended as it can cause microabrasions, increasing infection risk. While washing for at least 30 seconds is a good practice for thorough hand hygiene, hand positioning is critical during surgical hand-washing. Using alcohol-based hand rub alone is insufficient for surgical hand-washing as it may not effectively remove dirt, debris, and transient microorganisms.
2. When a healthcare professional makes an initial assessment of a client who is post-op following gastric resection, the client's NG tube is not draining. The healthcare professional's attempt to irrigate the tube with 10ml of 0.9% NaCl was unsuccessful, so they determine that the tube was obstructed. Which of the following actions should the healthcare professional take?
- A. Notify the healthcare provider.
- B. Attempt to irrigate the tube with a larger volume of saline.
- C. Replace the NG tube with a new one.
- D. Reposition the client to see if that helps the tube drain.
Correct answer: A
Rationale: If an NG tube is obstructed and cannot be irrigated successfully, notifying the healthcare provider is the appropriate action to take for further management. This is crucial as the healthcare provider may need to assess the situation, provide guidance, or intervene with specific interventions. Attempting to irrigate the tube with a larger volume of saline (Choice B) may exacerbate the situation if the tube is truly obstructed. Replacing the NG tube with a new one (Choice C) should not be the initial action unless advised by the healthcare provider. Repositioning the client (Choice D) may not necessarily resolve the tube obstruction and should not be the primary intervention in this scenario.
3. 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.
4. While being educated by a nurse, an assistive personnel (AP) is learning about proper hand hygiene. Which statement made by the AP indicates a good understanding of the teaching?
- A. There are times I should use soap and water rather than alcohol-based hand rub to clean my hands.
- B. I can use alcohol-based hand rub after using the restroom.
- C. Soap and water are only necessary if my hands are visibly dirty.
- D. Hand rub is always sufficient, regardless of the situation.
Correct answer: C
Rationale: Choice C is the correct answer because it demonstrates an understanding that soap and water should be used when hands are visibly dirty or when dealing with specific pathogens. Choice A is incorrect because it suggests the use of soap and water over alcohol-based hand rub without specifying the circumstances. Choice B is incorrect as it implies that using alcohol-based hand rub after using the restroom is always suitable. Choice D is incorrect because it states that hand rub is always enough, which is not true when hands are visibly soiled or when specific pathogens are present.
5. A client with diabetes mellitus is being taught by a nurse how to perform a capillary blood glucose test. Which of the following instructions should the nurse include in the teaching?
- A. Don sterile gloves after cleansing the site
- B. Puncture the site after cleansing and before the antiseptic dries
- C. Gently wipe the puncture site until a large droplet of blood forms
- D. Hold the finger below the heart level to puncture
Correct answer: B
Rationale: The correct instruction is to puncture the site after cleansing and before the antiseptic dries. This sequence helps ensure proper blood collection without introducing contaminants. Choice A is incorrect because wearing sterile gloves is not necessary for capillary blood glucose testing. Choice C is incorrect as wiping the puncture site can introduce contaminants and alter the blood sample. Choice D is incorrect as holding the finger below the heart level is not required for a capillary blood glucose test.
