Fundamentals of Nursing HESI

Correct Answer: A

Rationale: Elevating the head of the bed to 30-45 degrees is crucial in reducing the risk of aspiration because it helps keep the gastric contents lower than the esophagus, thereby promoting proper digestion and preventing reflux. This position also aids in reducing the likelihood of regurgitation and aspiration of gastric contents. Checking residual volumes every 4 hours is important for monitoring feeding tolerance but does not directly address the risk of aspiration. Verifying tube placement every shift is essential for ensuring the tube is correctly positioned within the gastrointestinal tract but does not directly reduce the risk of aspiration. Flushing the tube with water every 4 hours may help maintain tube patency and prevent clogging, but it does not specifically address the risk of aspiration associated with nasogastric tube feedings.

Correct Answer: B

Rationale: The correct intervention for a client with hypothyroidism is to encourage frequent rest periods. Hypothyroidism often leads to fatigue, making rest essential for recovery and symptom management. Providing a high-calorie diet is not necessary unless the client has gained weight due to hypothyroidism. Restricting fluid intake is not indicated unless there are specific medical reasons for it. Increasing iodine intake is not recommended for primary hypothyroidism, as it is typically caused by autoimmune thyroiditis or other factors rather than iodine deficiency.

Correct Answer: A

Rationale: The correct answer is A. Obtaining cotton balls for tracheostomy care is not recommended due to the risk of fiber contamination. Sterile gauze should be used instead. Choice B, using a sterile water bottle, is a correct and appropriate action for tracheostomy care to maintain cleanliness. Choice C, checking the suction equipment, is also a necessary step to ensure it is functioning properly for the procedure. Choice D, wearing a sterile gown, is a standard precaution to maintain a sterile environment during tracheostomy care.

Correct Answer: C

Rationale: The correct answer is to avoid taking antacids within 2 hours of phenytoin. Antacids can interfere with the absorption of phenytoin, reducing its effectiveness. Choice A is incorrect because phenytoin should not be taken with milk, as it may decrease its absorption. Choice B is unrelated to the medication and focuses on dental hygiene. Choice D is important but not directly related to phenytoin; it is more relevant to monitoring for adverse effects of the medication.

Correct Answer: A

Rationale: The correct answer is to make sure two fingers can fit under the sleeve. This allows for proper circulation and ensures that the sleeve is not too tight, which can lead to complications such as impaired blood flow or tissue damage. Choice B is incorrect because applying the sleeve tightly can actually cause harm rather than prevent blood clots. Choice C is incorrect as snugness alone may not guarantee proper fit. Choice D is incorrect as a sleeve that is too loose can be ineffective in providing the necessary compression.
