HESI Fundamentals Study Guide

Correct Answer: B

Rationale: The correct technique for surgical handwashing involves scrubbing with hands held higher than the elbows. This positioning helps prevent water from the contaminated area (the hands) from flowing towards the cleaner area (the elbows). This directional flow minimizes the risk of contaminating the scrubbed hands during the handwashing process. Choices A, C, and D are incorrect: A - having hands lower than elbows would risk contamination of the clean area, C - using a fist position does not ensure proper coverage and thorough handwashing, and D - placing hands on the chest is not part of the proper surgical handwashing technique.

Correct Answer: A

Rationale: Veracity involves telling the truth, a fundamental ethical principle in healthcare. In this scenario, the nurse demonstrates veracity by responding honestly when the client directly asks about her cancer diagnosis. Choice B is incorrect as avoiding discussing the diagnosis to prevent emotional distress does not align with veracity and transparency. Choice C is incorrect as providing a vague answer does not uphold the principle of truthfulness. Choice D is incorrect because promising to provide information only upon client request does not address the immediate question about the cancer diagnosis and lacks transparency.

Correct Answer: A

Rationale: Flushing the NG tube with water before and after medication administration is essential to ensure the tube is patent and prevent clogging. This action helps in clearing the tube and ensures that the medication is delivered properly. Administering medication with food (Choice B) may not be appropriate for all medications and can interfere with their absorption. Verifying tube placement by aspirating stomach contents (Choice C) is important but does not directly relate to ensuring proper medication administration. Diluting the medication with normal saline (Choice D) is not a standard practice for administering medications through an NG tube.

Correct Answer: A

Rationale: A testicular examination is appropriate for a 20-year-old male to screen for testicular cancer, which is more common in younger age groups. Testicular cancer is most frequently diagnosed in individuals between the ages of 15 and 40. Blood glucose screening is typically recommended for older individuals or those at risk for diabetes. Fecal occult blood testing is used for colorectal cancer screening, usually starting at age 50. Prostate-specific antigen testing is commonly considered for prostate cancer screening in older males, typically around age 50. Therefore, the most appropriate screening for the 20-year-old client is the testicular examination.

Correct Answer: B

Rationale: The most important initial action for the LPN/LVN to take in this situation is to measure the pulse volume and capillary refill distal to the infiltration. This assessment helps evaluate the severity of the infiltration and the circulation in the affected arm. Asking about past history of drug abuse or addiction (Choice A) is not the priority when addressing acute arm pain and infiltration. Compressing the infiltrated tissue (Choice C) may exacerbate the pain and is not recommended as the first step. Evaluating the extent of ecchymosis (Choice D) is not as critical as assessing the circulation in the affected arm, which is better addressed by measuring pulse volume and capillary refill.
