HESI RN
Adult Health 2 HESI Quizlet
1. A patient has a parenteral nutrition infusion of 25% dextrose. A student nurse asks the nurse why a peripherally inserted central catheter was inserted. Which response by the nurse is most appropriate?
- A. There is a decreased risk for infection when 25% dextrose is infused through a central line.
- B. The prescribed infusion can be given much more rapidly when the patient has a central line.
- C. The 25% dextrose is hypertonic and will be more rapidly diluted when given through a central line.
- D. The required blood glucose monitoring is more accurate when samples are obtained from a central line.
Correct answer: C
Rationale: The 25% dextrose solution is hypertonic. Shrinkage of red blood cells can occur when solutions with dextrose concentrations greater than 10% are administered IV. Blood glucose testing is not more accurate when samples are obtained from a central line. The infection risk is higher with a central catheter than with peripheral IV lines. Hypertonic or concentrated IV solutions are not given rapidly.
2. The nurse is administering an IV medication to a client with a history of anaphylaxis. Which intervention is most important for the nurse to implement?
- A. Stay with the client throughout the infusion.
- B. Keep emergency resuscitation equipment at the bedside.
- C. Obtain the client's allergy history.
- D. Ask the client about past allergic reactions to medications.
Correct answer: B
Rationale: Keeping emergency resuscitation equipment at the bedside is crucial in case the client experiences anaphylaxis during the infusion. While staying with the client throughout the infusion (Choice A) is important, having immediate access to emergency equipment takes priority in this situation. Obtaining the client's allergy history (Choice C) and asking about past allergic reactions to medications (Choice D) are relevant but do not address the immediate need for emergency intervention in case of anaphylaxis.
3. A nurse manager is reviewing data from the unit. More than 50% of new nurses hired left within 1 year of being hired. Which of the following implementations should the nurse manager consider to improve retention of newly hired nurses?
- A. Increase the length of time new hires spend in training.
- B. Conduct a performance review at 3, 6, and 9 months to review the new nurse’s weaknesses.
- C. Stress the importance of continuity of care to new hires.
- D. Build the manager’s own leadership skills through building relationships with staff members.
Correct answer: D
Rationale: To improve retention of newly hired nurses, the nurse manager should focus on building their own leadership skills and relationships with staff members. By creating a supportive environment and demonstrating effective leadership, the manager can positively impact staff retention. Options A, B, and C do not directly address the core issue of creating a supportive work environment and effective leadership, which are crucial for retaining newly hired nurses.
4. A client with severe acne is seen in the clinic, and the healthcare provider prescribes isotretinoin. The nurse reviews the client's medication record and would contact the healthcare provider if the client is taking which medication?
- A. Vitamin A
- B. Digoxin (Lanoxin)
- C. Furosemide (Lasix)
- D. Phenytoin (Dilantin)
Correct answer: A
Rationale: Isotretinoin is a metabolite of vitamin A, which can lead to toxicity when taken together. Therefore, it is crucial to avoid concurrent use of vitamin A supplements with isotretinoin. Contacting the healthcare provider to discuss discontinuing vitamin A supplements is important to prevent potential adverse effects. Choices B, C, and D are incorrect as they are not known to interact significantly with isotretinoin.
5. What do prokaryotic cells lack in comparison to eukaryotic cells?
- A. A defined nucleus and a series of membrane-bound organelles
- B. A defined nucleus and no membrane-bound organelles
- C. No defined nucleus and a series of membrane-bound organelles
- D. No defined nucleus and no membrane-bound organelles
Correct answer: D
Rationale: Prokaryotic cells are characterized by the absence of a defined nucleus and membrane-bound organelles. Choice A is incorrect because prokaryotic cells lack membrane-bound organelles. Choice B is incorrect because prokaryotic cells lack both a defined nucleus and membrane-bound organelles. Choice C is incorrect as prokaryotic cells have no defined nucleus. Therefore, the correct answer is D.
