1. What action should a healthcare professional planning to insert an IV for an older adult client take?
- A. Place the client’s arm in a dependent position.
- B. Place the client’s arm in a flexed position.
- C. Elevate the client’s arm to the level of the heart.
- D. Use a tourniquet above the insertion site.
Correct answer: A
Rationale: The correct action for a healthcare professional planning to insert an IV for an older adult client is to place the client’s arm in a dependent position. This positioning helps with vein prominence and facilitates easier IV insertion by enhancing blood flow and distending the veins. Placing the arm in a flexed position or elevating it to the level of the heart can impede vein visualization and make insertion more challenging. Using a tourniquet above the insertion site is a step in the IV insertion process but is not the initial action to take when preparing for the procedure.
2. The patient is being treated for cancer with weekly radiation therapy to the head and intravenous chemotherapy treatments. Which assessment is the priority?
- A. Feet
- B. Nail beds
- C. Perineum
- D. Oral cavity
Correct answer: D
Rationale: The correct answer is the oral cavity. During cancer treatment involving radiation to the head and intravenous chemotherapy, the oral cavity is a priority assessment area. Radiation can reduce salivary flow and lower the pH of saliva, which can lead to stomatitis and tooth decay. Assessing the oral cavity allows for the early identification and management of potential complications. Choice A, assessing the feet, is not the priority in this scenario as it is not directly impacted by the described cancer treatments. Choice B, assessing the nail beds, is not the priority compared to the oral cavity. Nail bed assessment may be relevant for certain conditions, but in this case, the oral cavity is of higher priority due to the specific treatment effects. Choice C, assessing the perineum, is also not the priority in this situation as it is not directly affected by the described cancer treatments, unlike the oral cavity.
3. In a disaster at a child day care center, which child would the triage nurse prioritize for treatment last?
- A. An infant with intermittent bulging anterior fontanel between crying episodes
- B. A toddler with severe deep abrasions covering 98% of the body
- C. A preschooler with a lower leg fracture and an upper leg fracture on the other leg
- D. A school-age child with singed eyebrows and hair on the arms
Correct answer: B
Rationale: The toddler with severe deep abrasions covering 98% of the body would be prioritized for treatment last because these extensive injuries may require immediate attention and resources. The other choices present serious conditions but are not as severe or life-threatening as the toddler's injuries. The infant with an intermittent bulging anterior fontanel may have signs of increased intracranial pressure, requiring prompt evaluation. The preschooler's fractures, though serious, can be managed without immediate critical intervention. The school-age child with singed eyebrows and hair may have suffered burns but does not exhibit injuries as severe as the toddler's deep abrasions.
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 caring for a client receiving total parenteral nutrition (TPN). Which laboratory value should be monitored closely to assess for complications?
- A. Serum sodium
- B. Serum calcium
- C. Blood urea nitrogen (BUN)
- D. Blood glucose
Correct answer: D
Rationale: The correct answer is D: Blood glucose. Monitoring blood glucose levels is crucial for clients receiving total parenteral nutrition (TPN) due to the high glucose content in TPN solutions. TPN delivers essential nutrients, including glucose, directly into the bloodstream. Clients on TPN are at risk of developing hyperglycemia due to the concentrated glucose infusion. Therefore, close monitoring of blood glucose levels is necessary to detect and prevent hyperglycemia-related complications such as osmotic diuresis, hyperosmolarity, and electrolyte imbalances. While serum sodium, serum calcium, and blood urea nitrogen (BUN) levels are important parameters in various clinical scenarios, they are not specifically associated with TPN administration. These values are not the primary indicators to assess for complications in clients receiving TPN.
