HESI Fundamentals Practice Exam

Correct Answer: B

Rationale: Repositioning the client's arm is the initial action to take when encountering an obstruction with an antecubital saline lock. Repositioning may correct any bending at the elbow that could be causing the obstruction, allowing for smoother infusion flow. Checking for a blood return, removing the IV site dressing, or flushing the lock with saline would be subsequent actions once the obstruction is addressed. Checking for a blood return is done to confirm proper placement, removing the IV site dressing is necessary for site assessment, and flushing the lock with saline helps maintain patency but should not be the first action when an obstruction is detected.

Correct Answer: D

Rationale: Orthopnea (D) is most consistent with left-sided heart failure. It is characterized by difficulty breathing when lying flat and is relieved by sitting up or standing. Dependent edema (A), ascites (B), and nocturia (C) are more commonly associated with right-sided heart failure. Dependent edema refers to swelling due to fluid accumulation, ascites is the accumulation of fluid in the peritoneal cavity, and nocturia is the excessive need to urinate during the night, all of which are more indicative of right-sided heart failure.

Correct Answer: D

Rationale: The priority for the nurse is to educate the client on the importance of personal hygiene during menstruation. Although it's crucial to respect the client's beliefs, providing education ensures the client receives accurate information to make informed decisions about her hygiene practices. By offering teaching first, the nurse can address any misconceptions or concerns the client may have while promoting optimal hygiene practices for overall well-being. Choice A should not be the first action as it does not address the client's potential misinformation about hygiene. Choice B is not ideal as it only offers a temporary solution without addressing the underlying issue. Choice C is not the priority as the immediate concern is the client's personal hygiene practices.

Correct Answer: D

Rationale: When performing sterile wound care, it is essential to use only newly opened and unexpired solutions to maintain sterility and prevent infections. The normal saline solution obtained by the nurse is labeled 'opened' and dated 48 hours prior to the current date, making it no longer considered sterile. The best action for the nurse to take in this situation is to discard the saline solution and obtain a new unopened bottle to ensure the safety and effectiveness of wound care. Choices A, B, and C are incorrect because reusing an already opened and outdated solution or attempting to relabel it with a current date can compromise patient safety and increase the risk of infection.

Correct Answer: B

Rationale: After ensuring the correct placement of the NGT, the nurse should flush the tube with water to prevent any obstructions and ensure proper medication delivery. Flushing the tube is essential before, after, and in between each medication administration. Clamping the tube for 20 minutes should be done after all medications are administered to prevent clogging. Administering medications as prescribed and preparing medications by crushing tablets and dissolving them in sterile water should only be done after the tube has been appropriately flushed to maintain its patency and effectiveness.
