HESI Fundamentals Exam

Correct Answer: A

Rationale: To calculate the mL to administer, use the formula: Dose required (mg) � Stock concentration (mg/mL) = Volume to administer (mL). In this case, 10 mg � 40 mg/mL = 0.25 mL. However, when rounding to the nearest tenth, the answer should be 0.3 mL. Therefore, the nurse should administer 0.3 mL. Choice A is the correct answer. Choice B (0.25 mL) is the result obtained before rounding. Choice C (0.4 mL) and Choice D (0.5 mL) are incorrect calculations.

Correct Answer: C

Rationale: The correct instruction the nurse should include is to rotate injection sites within the same body area. This practice helps prevent lipodystrophy, a condition characterized by the thickening or thinning of subcutaneous fat at the injection sites, which can affect insulin absorption. Choice A is incorrect because administering insulin in the same area each time can lead to lipodystrophy. Choice B is incorrect as insulin should be stored according to the manufacturer's instructions, which may include refrigeration. Choice D is incorrect because the angle of insulin injection (usually 90 degrees) is determined by the length of the needle and the amount of subcutaneous fat, not a fixed 45-degree angle.

Correct Answer: A

Rationale: To maintain patency of the NG tube, it is essential to irrigate the tube with normal saline every shift. This action helps prevent clogging and ensures that the tube remains clear for effective decompression. Checking tube placement by auscultation (Choice B) is important for verifying correct placement but does not directly impact patency. Securing the tube to the client's gown (Choice C) is crucial for safety and comfort but is not directly related to maintaining patency. Flushing the tube with sterile water before and after medication administration (Choice D) is not the recommended method for maintaining patency of an NG tube, as normal saline is the appropriate solution for this purpose.

Correct Answer: C

Rationale: The correct answer is C: Skim milk, turkey salad, roll, and vanilla ice cream. These items are low in sodium, making it a suitable meal for someone on a low-sodium diet. Skim milk, turkey salad, and vanilla ice cream are naturally low in sodium, while the roll can be selected as a low-sodium option. Choices A, B, and D contain items that are typically high in sodium, such as bacon, clam chowder, crackers, and cheese, making them unsuitable for a low-sodium diet.

Correct Answer: D

Rationale: The correct answer is D: 'Effectiveness of the last dose of pain medication.' When transferring a client to a long-term care facility, it is crucial to provide information on the effectiveness of the last dose of pain medication to ensure continuity of care and appropriate pain management. This information helps the receiving facility understand the client's current pain status and plan future interventions accordingly. Choices A, B, and C are less relevant for the handoff report in this scenario. The frequency of previous vital sign measurements may be important, but the immediate effectiveness of pain medication takes precedence. The number of family members who have visited and the time of the client's last bath are not as critical for the receiving facility's immediate care planning compared to pain management details.
