HESI Fundamentals Study Guide

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.

Correct Answer: A

Rationale: The correct answer is weight gain. In hypothyroidism, there is a decrease in metabolic rate, which can lead to weight gain. Heat intolerance (choice B) is more commonly associated with hyperthyroidism. Increased appetite (choice C) and frequent diarrhea (choice D) are not typical findings in hypothyroidism. Therefore, choices B, C, and D are incorrect.

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: B

Rationale: After reviewing the expected outcomes in the plan of care, the nurse should obtain current client data to compare with these outcomes. This step is crucial in determining the effectiveness of the care provided. Choice A is incorrect because determining the realism of expected outcomes comes after assessing current client data. Choice C is incorrect as modifying nursing interventions should be based on the data comparison rather than done immediately after reviewing expected outcomes. Choice D is also incorrect as reviewing professional standards of care is important but not the immediate next step in evaluating care effectiveness.

Correct Answer: A

Rationale: The correct answer is A: 'Potassium 5.4'. A potassium level of 5.4 is elevated (normal range is typically 3.5-5.0 mEq/L) and may indicate hyperkalemia, which can have serious cardiac implications. Elevated potassium levels can lead to life-threatening arrhythmias, so immediate reporting and intervention are necessary. Choice B, 'Sodium 140', falls within the normal range (135-145 mEq/L) and does not require immediate reporting. Choice C, 'Calcium 8.6', falls within the normal range (8.5-10.5 mg/dL) and is not an immediate concern. Choice D, 'Magnesium 2.0', is within the normal range (1.5-2.5 mEq/L) and does not need urgent reporting. Therefore, the nurse should prioritize reporting the elevated potassium level as it poses the most immediate risk.
