HESI Fundamentals Study Guide
1. When admitting a 5-month-old who has vomited 9 times in the past 6 hours, what should the healthcare provider observe for signs of which overall imbalance?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Increased serum hemoglobin levels
- D. Decreased serum potassium levels
Correct answer: B
Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.
2. A client who is postoperative has paralytic ileus. Which of the following abdominal assessments should the nurse expect?
- A. Absent bowel sounds with distention
- B. Hyperactive bowel sounds with pain
- C. Normal bowel sounds with cramping
- D. Diminished bowel sounds with tenderness
Correct answer: A
Rationale: Paralytic ileus is a condition where there is a temporary paralysis of the bowel, leading to absent bowel sounds and abdominal distention. This occurs because the bowel is not functioning properly to propel contents, resulting in a lack of bowel sounds. Absent bowel sounds with distention are typical findings in paralytic ileus. Hyperactive bowel sounds with pain are more indicative of increased motility and are not expected in paralytic ileus. Normal bowel sounds with cramping may be seen in other conditions, such as gastroenteritis. Diminished bowel sounds with tenderness are not typical findings in paralytic ileus.
3. A client receiving chlorpromazine HCL (Thorazine) is in psychiatric home care. During a home visit, the nurse observes the client smacking her lips alternately with grinding her teeth. The nurse recognizes this assessment finding as what?
- A. Dystonia
- B. Akathisia
- C. Bradykinesia
- D. Tardive dyskinesia
Correct answer: D
Rationale: The correct answer is D: Tardive dyskinesia. Tardive dyskinesia is a potential side effect of long-term antipsychotic use, characterized by involuntary movements like lip smacking and repetitive, purposeless movements. Choice A, dystonia, presents with sustained or repetitive muscle contractions. Choice B, akathisia, involves motor restlessness and a compelling need to be in constant motion. Choice C, bradykinesia, refers to slowness of movement typically seen in Parkinson's disease, not lip smacking and teeth grinding, which are indicative of tardive dyskinesia.
4. A nurse on a med-surg unit is providing care for four clients. The nurse should identify which of the following situations as an ethical dilemma?
- A. A surgeon who removed the wrong kidney during a surgical procedure refuses to take responsibility for her actions
- B. A client who has a new colostomy refuses to follow instructions from the ostomy therapist because she 'doesn’t like him'
- C. The family of a client who has a terminal illness asks that the provider not disclose the diagnosis to the client
- D. A client who has Crohn’s disease reports that his prescription drug plan will not cover his medications
Correct answer: C
Rationale: The correct answer is C. It is an ethical dilemma when the family of a client with a terminal illness asks healthcare providers not to inform the client of their diagnosis. This situation poses a conflict between respecting the client's right to know the truth about their condition (autonomy and truth-telling principles) and honoring the family's wishes. Choices A, B, and D do not present ethical dilemmas. Choice A involves professional accountability and responsibility, Choice B involves a client's personal preference, and Choice D involves financial challenges.
5. A caregiver of an immobile client requiring assistance with repositioning is being taught by a nurse on preventing back strain. Which statement by the caregiver indicates an understanding of the teaching?
- A. I will place the bed in the lowest position
- B. I will tighten my abdominal muscles prior to moving
- C. I will keep my legs straight to provide more power in the lift
- D. I will twist at the waist while pulling the draw sheet
Correct answer: B
Rationale: The correct answer is B. Tightening the abdominal muscles before moving helps protect the back by providing core support. Keeping the legs straight (choice C) is incorrect as bending the legs is recommended to provide a stable base and prevent strain on the back. Twisting at the waist (choice D) while moving can cause back injury due to the strain on the spine. Placing the bed in the lowest position (choice A) is not directly related to preventing back strain during client repositioning, although it may be necessary for other reasons.
