HESI Fundamentals Study Guide Questions
Question 1 of 5
A healthcare professional is preparing to administer 0.9% sodium chloride (0.9% NaCl) 250 mL IV to infuse over 30 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the healthcare professional adjust the manual IV infusion to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)
Correct Answer: C
Rationale: To administer 250 mL over 30 min with a drop factor of 10 gtt/mL, the healthcare professional should adjust the IV infusion to deliver 100 gtt/min. The correct calculation is: (250 mL · 30 min) x 10 gtt/mL = 100 gtt/min. This rate ensures the proper administration of the IV solution within the specified time frame. Choices A, B, and D are incorrect as they do not align with the accurate calculation based on the provided data.
Question 2 of 5
A healthcare professional is preparing to inject heparin subcutaneously for a client who is postoperative. Which of the following actions should the healthcare professional take?
Correct Answer: B
Rationale: For subcutaneous injections like heparin, a 25-27 gauge needle is recommended, making choice A incorrect. The abdomen is a commonly used site for heparin injection due to its consistent absorption and convenience, making choice B the correct answer. The Z-track technique is not necessary for subcutaneous injections, making choice C unnecessary. Observing for bleb formation is not a standard practice for confirming proper placement of subcutaneous heparin, making choice D incorrect. Therefore, the correct action is to select a site on the client's abdomen for the injection.
Question 3 of 5
A client has been sitting in a chair for 1 hour. Which of the following complications poses the greatest risk to the client?
Correct Answer: C
Rationale: The correct answer is C: Pressure injury. Prolonged sitting can lead to pressure injuries due to continuous pressure on certain body areas, reducing blood flow and causing tissue damage. While decreased subcutaneous fat, muscle atrophy, and fecal impaction are potential concerns, pressure injuries pose the greatest immediate risk as they can lead to serious complications such as tissue necrosis and infection if not addressed promptly. Decreased subcutaneous fat and muscle atrophy may develop over time with prolonged immobility but are not as acutely dangerous as a pressure injury. Fecal impaction, while uncomfortable and potentially serious, does not pose an immediate life-threatening risk compared to the development of a pressure injury.
Question 4 of 5
A nurse is caring for a client who has terminal lung cancer. The nurse observes the client's family assisting with all ADLs. Which of the following rationales for self-care should the nurse communicate to the family?
Correct Answer: C
Rationale: The correct answer is C. In situations like terminal illness, allowing clients to perform activities of daily living (ADLs) can help maintain their sense of control and dignity, providing comfort and a sense of normalcy amidst their health challenges. Choice A is incorrect because in a terminal stage, the focus is not on muscle strength or promoting physical healing but rather on enhancing the client's emotional well-being. Choice B, while highlighting the importance of privacy, is not directly addressing the client's need for control and autonomy. Choice D is incorrect as the priority in this scenario is not related to discharge requirements but rather the client's emotional and psychological needs during their terminal illness.
Question 5 of 5
A nurse in a provider's office is preparing to assess a young adult client's musculoskeletal system as part of a comprehensive physical examination. Which of the following findings should the nurse expect?
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.
