HESI CAT Exam

Correct Answer: B

Rationale: Frequent reorientation is crucial for clients with neurological impairments from osmotic demyelination to prevent confusion and assist with orientation. It helps maintain a proper sense of time, place, and person, reducing disorientation. Patching one eye (Choice A) is not a priority intervention for osmotic demyelination and does not address the immediate need for reorientation. Range of motion exercises (Choice C) may be important for overall care, but reorientation takes precedence due to its impact on neurological functioning. Evaluating swallow (Choice D) is not the primary intervention needed for osmotic demyelination; it is essential but not the first priority.

Correct Answer: A

Rationale: The best way to evaluate the effectiveness of a new fall prevention protocol is by comparing the number of falls that occurred before and after its implementation. This direct comparison helps in assessing the impact of the protocol on reducing fall rates. Choices B, C, and D do not directly measure the effectiveness of the protocol. Analyzing costs incurred (Choice B), conducting a chart review (Choice C), or consulting with a physical therapist (Choice D) may provide valuable information but do not specifically evaluate the protocol's effectiveness in preventing falls.

Correct Answer: C

Rationale: Thiamine supplementation is critical in preventing Wernicke's syndrome, especially in clients with chronic alcohol use. Wernicke's syndrome is a neurological disorder caused by thiamine deficiency. Lorazepam is a benzodiazepine used for anxiety and not for preventing Wernicke's syndrome. Famotidine is an H2 blocker used to reduce stomach acid production but does not prevent Wernicke's syndrome. Atenolol is a beta-blocker used for hypertension and angina, not for preventing Wernicke's syndrome.

Correct Answer: A

Rationale: The vastus lateralis is the preferred site for IM injections in infants due to their limited muscle mass and safety. Infants do not have well-developed muscle mass, making the vastus lateralis the best option for IM injections. The deltoid muscle is typically used for older children and adults. Ventrogluteal and dorsogluteal sites are not recommended for infants due to safety concerns, including the risk of damaging the sciatic nerve. Therefore, the correct choice is the vastus lateralis for IM injections in infants.

Correct Answer: D

Rationale: The correct answer is D because an illiterate client may require additional support to ensure they fully comprehend the information provided in the informed consent process. It is crucial to confirm that the client truly understands the nature of the procedure, its risks, and benefits. While it is important to assess pain control (choice A), a client's previous medication administration does not directly impact their ability to understand the consent process. Choice B, a 15-year-old primigravida who has been self-supporting, may legally provide informed consent depending on the jurisdiction and circumstances, so this situation may not require further exploration. Choice C, explaining a procedure by a different specialist, does not necessarily require additional exploration before witnessing the client's consent.
