HESI Practice Test for Fundamentals

Correct Answer: B

Rationale: The LPN should monitor potassium levels closely while the client is taking furosemide (Lasix) due to the medication's potential to cause hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Hypokalemia can result in serious complications such as cardiac dysrhythmias. Monitoring sodium levels (choice A) is important but not as critical as monitoring potassium in this context. Calcium (choice C) and magnesium (choice D) levels are not typically affected by furosemide and are not the priority for monitoring in this scenario.

Correct Answer: A

Rationale: The nurse's priority should be the client's temperature. A high temperature of 39.2 degrees C (102 degrees F) indicates a potential infection or inflammation that requires immediate attention. While heart rate and abdominal tenderness are important assessments, the temperature takes precedence as it signals a more urgent issue. Overdue menses, although significant, are not the priority in this scenario when compared to the possibility of an acute infection or inflammatory process.

Correct Answer: C

Rationale: The correct answer is C. An incident report should be completed when a nurse administers medication to a client significantly earlier than the scheduled time. This deviation from the prescribed schedule could potentially impact the client's treatment plan and requires documentation for proper evaluation and follow-up. Choices A, B, and D do not necessarily require an incident report. Choice A involves improper restraint application, which is a safety issue but does not directly involve medication administration. Choice B involves a protective measure for a client with TB, which is within the scope of practice for assistive personnel. Choice D describes an increase in IV fluid administration, which may need monitoring but does not necessarily indicate a need for an incident report unless there are specific complications or adverse effects related to the additional fluid.

Correct Answer: A

Rationale: The correct answer is A: Chicken breast. In chronic kidney disease, a low-protein diet is often recommended to reduce the workload on the kidneys. Chicken breast is a high-protein food that should be limited in such diets to help manage the progression of kidney disease. Choices B, C, and D are low in protein and are generally suitable for individuals following a low-protein diet. Apples, rice, and bananas can be included in moderation as part of a balanced diet for individuals with chronic kidney disease.

Correct Answer: B

Rationale: Edema, indicated by 2+ edema of fingers and hands, can impair blood flow and peripheral perfusion, leading to reduced oxygen saturation readings on a pulse oximeter. High blood pressure (choice A) would not directly affect oxygen saturation readings. Radial pulse volume (choice C) and capillary refill time (choice D) are more related to assessing circulation rather than contributing significantly to oxygen saturation readings.
