HESI Fundamentals Study Guide

Correct Answer: B

Rationale: When assessing a young adult's musculoskeletal system, the nurse should expect an exaggerated lumbar curvature (lordosis). This is a normal finding in young adults due to the natural curvature of the spine. Concave thoracic spine posteriorly (choice A) and concave lumbar spine posteriorly (choice C) are not typical findings as the spine should have normal curvatures. Exaggerated thoracic curvature (choice D) is also not a typical finding in young adults.

Correct Answer: C

Rationale: The correct position for a postoperative client using an incentive spirometer is the Semi-Fowler's position. Placing the client in Semi-Fowler's or high-Fowler's position maximizes lung expansion and the effectiveness of the incentive spirometer. Side-lying may not provide optimal lung expansion. The supine position is not ideal for postoperative clients using incentive spirometers as it may limit lung expansion. The Trendelenburg position is not recommended due to potential complications postoperatively.

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.

Correct Answer: D

Rationale: During a change-of-shift report, healthcare professionals should include the medication regimen from the medication administration record. This information ensures continuity of care and helps incoming staff understand the patient's medication needs and schedule. While input and output measurements, blood pressure readings, and scheduled procedures like a bone scan are important aspects of patient care, they may not be immediately relevant for the incoming shift. Focusing on medication details helps prevent errors and ensures the patient receives the correct medications at the right times.

Correct Answer: A

Rationale: Severe diarrhea can lead to metabolic acidosis due to the loss of bicarbonate. When there is excessive loss of bicarbonate through diarrhea, the pH of the blood decreases, leading to metabolic acidosis. Metabolic alkalosis (Choice B) is not typically associated with severe diarrhea as it involves elevated pH and bicarbonate levels. Hyperkalemia (Choice C) is less likely with severe diarrhea as potassium is often lost along with fluids. Hypercalcemia (Choice D) is not a common complication of severe diarrhea; instead, hypocalcemia may occur due to malabsorption of calcium.
