Practice HESI Fundamentals Exam
1. A client with diabetes mellitus is being taught by a nurse about mixing regular and NPH insulin. Which of the following statements by the client indicates an understanding of the teaching?
- A. I should roll the NPH vial between my hands before drawing it up.
- B. I should draw up the NPH insulin before the regular insulin.
- C. I should inject air into the vial of regular insulin first.
- D. I should wait 10 minutes after mixing the insulin to inject it.
Correct answer: A
Rationale: The correct answer is A. Rolling the NPH vial between the hands before drawing it up ensures proper mixing of the insulin. Choice B is incorrect because regular insulin should be drawn up first to avoid contamination. Choice C is incorrect as injecting air into the vial of regular insulin is not necessary. Choice D is incorrect as there is no need to wait 10 minutes after mixing the insulin before injecting it.
2. Which of the following manifestations confirms the presence of pediculosis capitis in students?
- A. Scratching the head more than usual
- B. Flakes evident on a student's shoulders
- C. Oval pattern occipital hair loss
- D. Whitish oval specks sticking to the hair
Correct answer: D
Rationale: The correct answer is D. Whitish oval specks sticking to the hair shaft are nits, which are a definitive sign of pediculosis capitis (head lice). A: Scratching the head more than usual is a common symptom but not confirmatory of head lice infestation. B: Flakes evident on a student's shoulders may indicate dandruff or dry scalp, not necessarily head lice. C: Oval pattern occipital hair loss is not a typical manifestation of pediculosis capitis.
3. Which of the following findings contraindicate the use of haloperidol (Haldol) and warrant withholding the dose?
- A. Drowsiness, lethargy, and inactivity
- B. Dry mouth, nasal congestion, and blurred vision
- C. Rash, blood dyscrasias, severe depression
- D. Hyperglycemia, weight gain, and edema
Correct answer: C
Rationale: The correct answer is C: Rash, blood dyscrasias, and severe depression are serious side effects of haloperidol that necessitate withholding the dose and prompt further evaluation. Rash can indicate an allergic reaction, blood dyscrasias are serious blood disorders that can be life-threatening, and severe depression may worsen with haloperidol use. Choices A, B, and D are incorrect because drowsiness, lethargy, inactivity, dry mouth, nasal congestion, blurred vision, hyperglycemia, weight gain, and edema are common side effects of haloperidol that may not necessarily contraindicate its use but should be monitored and managed appropriately.
4. The nurse is caring for a client with a central venous catheter. What is the most important action for the nurse to take to prevent infection?
- A. Change the catheter dressing every 72 hours.
- B. Flush the catheter with heparin solution daily.
- C. Ensure the catheter is clamped when not in use.
- D. Maintain sterile technique when handling the catheter.
Correct answer: D
Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. Changing the catheter dressing every 72 hours, while important for overall catheter care, does not directly address infection prevention. Flushing the catheter with heparin solution daily is essential for maintaining patency but does not primarily prevent infections. Ensuring the catheter is clamped when not in use is important for preventing air embolism but is not the most critical action to prevent infection. The most effective way to prevent infections is by strictly adhering to sterile techniques during catheter handling, which minimizes the risk of introducing pathogens into the catheter site.
5. After a client's death in a long-term care facility, identify the correct sequence of steps for the nurse to perform.
- A. 1) Place a name tag on the body 2) Obtain the pronouncement of death from the provider 3) Remove tubes and indwelling lines 4) Wash the client's body 5) Ask the client's family members if they would like to view the body
- B. 2) Obtain the pronouncement of death from the provider 3) Remove tubes and indwelling lines 4) Wash the client's body 5) Ask the client's family members if they would like to view the body 1) Place a name tag on the body
- C.
- D.
Correct answer: B
Rationale: The correct sequence of steps for the nurse in a long-term care facility after a client's death is as follows: First, obtain the pronouncement of death from the provider. Second, remove tubes and indwelling lines before proceeding to wash the client's body. Third, ask the client's family members if they would like to view the body. Finally, place a name tag on the body. This order ensures that the necessary procedures are followed with respect and consideration for the deceased client and their family. Choice B is correct. Choices A, C, and D are incorrect as they do not follow the appropriate sequence of actions required in this situation.
