Fundamentals of Nursing HESI

Correct Answer: C

Rationale: Infusing 10% dextrose and water at 54 ml/hr is the correct action to prevent hypoglycemia until the next TPN solution becomes available. This solution will help maintain the client's glucose levels. Infusing normal saline at a keep-vein-open rate (Choice A) is not appropriate for maintaining glucose levels and would not address the nutritional needs provided by TPN. Discontinuing the IV and flushing the port with heparin (Choice B) is unnecessary and not indicated in this situation as the client still needs fluid and nutrition. Obtaining a stat blood glucose level and notifying the healthcare provider (Choice D) can be done later but is not the immediate action required when the TPN solution has run out.

Correct Answer: C

Rationale: Inspiratory crackles are a common finding in patients with congestive heart failure due to the accumulation of fluid in the lungs, leading to crackling sounds during inspiration. Chest pain (Choice A) is more commonly associated with conditions like angina or myocardial infarction and is not a typical symptom of congestive heart failure. Pallor (Choice B) is a general symptom of various conditions and not specific to congestive heart failure. While a heart murmur (Choice D) may be heard in some cases of congestive heart failure, it is not as consistent as inspiratory crackles in indicating the condition.

Correct Answer: B

Rationale: The correct action for the nurse to take when measuring a client's oral temperature using an electronic thermometer is to inquire whether the client has smoked in the last 30 minutes. Smoking can affect the accuracy of oral temperature readings. Providing oral hygiene (Choice A) is not directly related to ensuring accurate temperature measurement. Connecting the red tip probe (Choice C) is not specific to oral temperature measurement accuracy. Positioning the probe tip against the buccal mucosa (Choice D) is incorrect as oral temperature is typically measured under the tongue, not against the cheek.

Correct Answer: B

Rationale: The correct answer is to emphasize emptying the child's mouth in any case of possible poisoning. This action is crucial to prevent further ingestion of the poisonous substance. Choice A is incorrect because calling the Poison Control Center should be one of the first steps, not waiting until the situation is identified. Choice C is incorrect as moving the child may spread or exacerbate the effects of the toxic substance. Choice D is incorrect because inducing vomiting can be harmful if the poison is a hydrocarbon, as it may lead to aspiration.

Correct Answer: B

Rationale: When cimetidine decreases the metabolism of imipramine, it leads to an increased concentration of imipramine in the body, which can result in imipramine toxicity. This increased risk of toxicity is the likely effect of this drug interaction. Choice A is incorrect because cimetidine's effect on imipramine metabolism does not impact the therapeutic effects of cimetidine. Choice C is incorrect because the interaction does not decrease the risk of adverse effects of cimetidine. Choice D is incorrect as the increased concentration of imipramine can lead to toxicity, not increased therapeutic effects.
