A nurse is caring for a client who has just had a central venous catheter placed via the right subclavian vein. Which of the following actions should the nurse take?

The correct answer is choice C: Blood pressure change from 118/78 mm Hg to 86/50 mm Hg.

Choice C rationale: A significant drop in blood pressure can indicate various serious conditions, such as shock, hemorrhage, or a severe infection. The nurse should assess the client further and intervene as necessary to prevent complications.

Choice A rationale: The change in temperature may indicate the onset of a fever and requires further assessment, but it is not as immediately concerning as the sudden drop in blood pressure.

Choice B rationale: The change in respiratory rate could be a result of factors like pain, anxiety, or exercise. While it warrants further assessment, it is not as critical as the blood pressure change.

Choice D rationale: The heart rate change may be a response to medications, rest, or other factors. It should be monitored and assessed, but the priority finding is the blood pressure change, which may indicate a more severe underlying issue.

The correct answer is Choice A, Choice D.

Choice A rationale: Tachycardia, or an increased heart rate, is a common symptom of dehydration in infants. The body attempts to maintain adequate blood circulation despite reduced fluid volume by increasing the heart rate, which is a compensatory mechanism.

Choice B rationale: Bloating is not typically associated with dehydration in infants. Dehydration usually results in symptoms like dry mucous membranes and decreased skin turgor, rather than gastrointestinal symptoms like bloating.

Choice C rationale: Hypertension, or high blood pressure, is uncommon in dehydrated infants. Dehydration generally leads to hypotension (low blood pressure) due to decreased fluid volume in the circulatory system, which can result in reduced blood pressure.

Choice D rationale: Irritability is a frequent symptom of dehydration in infants. Reduced fluid intake and electrolyte imbalances can cause discomfort and distress, leading to irritability and increased fussiness in dehydrated infants.
