HESI Fundamentals Exam

Correct Answer: A

Rationale: To calculate the mL/hr rate for the infusion, divide the total volume (750 mL) by the total time (7 hours). 750 mL � 7 hours = 107 mL/hr. This means that the pump should be set to deliver approximately 107 mL/hr. Choice B (75 mL/hr) is incorrect because it does not reflect the correct calculation. Choice C (90 mL/hr) is incorrect as it does not align with the accurate calculation. Choice D (60 mL/hr) is incorrect as it does not match the correct mL/hr rate obtained through the calculation.

Correct Answer: A

Rationale: The correct action the nurse should take first is to auscultate bowel sounds. This step is crucial to assess bowel activity before proceeding with palpation or administering medications. Assessing bowel sounds can provide valuable information about bowel motility and potential obstructions. Administering an antiemetic or offering pain medication may be necessary but should come after assessing bowel sounds to ensure appropriate treatment. Palpating the abdomen should be avoided initially to prevent potential discomfort or complications, especially if there is suspected abdominal pathology.

Correct Answer: B

Rationale: When caring for a client with dementia, it is crucial to understand that confusion often arises after relocating to new surroundings. This change can disrupt familiar routines and trigger increased disorientation and confusion. Choice A is correct because confusion in the elderly is not a normal part of aging. Choice C is incorrect because confusion in dementia is primarily due to changes in the brain associated with the disease, not just irreversible brain pathology. Choice D is incorrect because while adequate sleep is important for overall health, it alone cannot prevent or cure confusion associated with dementia.

Correct Answer: B

Rationale: The correct answer is B, 'Allergic to shellfish.' An allergy to shellfish can indicate a sensitivity to iodine, which is used in the contrast dye for an IVP, posing a risk of an allergic reaction. Reflex incontinence (Choice A) is not directly related to the potential hazard of an IVP. Claustrophobia (Choice C) and hypertension (Choice D) are also not significant factors that indicate a potential hazard for an IVP.

Correct Answer: D

Rationale: The correct answer is D: Joint contractures. When a healthcare provider performs passive ROM and splinting on a patient, the goal is to prevent joint contractures. Joint contractures result from immobility and can lead to permanent stiffness and decreased range of motion. Atelectasis (choice A) is a condition where there is a complete or partial collapse of the lung, commonly due to immobility, but not directly related to passive ROM or splinting. Renal calculi (choice B) are kidney stones and are not typically associated with ROM exercises. Pressure ulcers (choice C) result from prolonged pressure on the skin and are prevented by repositioning the patient, not specifically addressed by ROM and splinting exercises.
