HESI Fundamentals Practice Exam

Correct Answer: A

Rationale: The ventrogluteal site is the preferred location for administering large volume IM injections to avoid nerve injury. This site is situated away from major nerves and blood vessels, reducing the risk of complications associated with injecting into other areas. The ventrogluteal site allows for deep muscle penetration and is recommended for injections over 2 mL in volume to ensure proper dispersion and absorption of the medication. Choices B, C, and D are incorrect because the outer upper quadrant of the buttock is not the recommended site for large volume injections, two inches below the acromion process is a location for a deltoid injection, and the vastus lateralis is typically used for smaller volume injections.

Correct Answer: C

Rationale: To assess fever patterns accurately, the nurse should measure the client's temperature at regular intervals. This approach helps in identifying the pattern of fever spikes and fluctuations, which can provide valuable information for diagnostic and treatment purposes. Assessing for flushed, warm skin or documenting circadian rhythms may not directly reveal the fever pattern, while varying temperature measurement sites could lead to inconsistent readings. Therefore, measuring temperature at regular intervals is the most appropriate intervention to identify fever patterns in this scenario.

Correct Answer: D

Rationale: The correct instruction for a UAP caring for a client with MRSA under contact precautions is to don a gown and gloves when entering the client's room. This precaution is essential to prevent the spread of MRSA and protect both the client and the healthcare worker from potential infection. Choice A is incorrect because visitors should not be restricted solely based on contact precautions. Choice B is incorrect as wearing sterile gloves is not necessary, standard precautions with regular gloves are sufficient. Choice C is incorrect because the client wearing a mask is not a standard practice for contact precautions; it is the healthcare worker who should take preventive measures.

Correct Answer: C

Rationale: To maintain patency and ensure proper medication delivery, water should be instilled into the feeding tube between administering the two medications. This helps prevent clogging of the tube and ensures that both medications are delivered effectively without interference from remnants of the previous medication. Diluting the medications with sterile water before administration (choice A) is unnecessary and may alter the medication concentration. Mixing the medications in one syringe (choice B) could lead to interactions or chemical reactions between the medications. Withdrawing fluid from the tube before instilling each medication (choice D) is not required and may increase the risk of tube displacement or misplacement.

Correct Answer: B

Rationale: The correct position for the drainage container after inserting an indwelling catheter is to have it placed lower than the bladder. This positioning helps maintain a constant downward flow of urine from the bladder, preventing backflow and ensuring proper drainage. Choice A is incorrect because having the drainage tubing taut does not promote proper urine flow and may cause kinking. Choice C is incorrect as placing the container at the head of the bed does not affect drainage and is not necessary for accurate measurement. Choice D is incorrect as the positioning of the drainage container should prioritize proper drainage and care over potential embarrassment.
