HESI RN CAT Exam Quizlet

Correct Answer: C

Rationale: The correct intervention for a client at risk for developing deep vein thrombosis (DVT) is to encourage early ambulation. Early ambulation helps prevent DVT by promoting circulation, reducing stasis, and preventing blood clot formation. Maintaining the client on bed rest (Choice A) would increase the risk of DVT due to decreased mobility. Applying warm, moist compresses to the legs (Choice B) can be beneficial for other conditions but does not directly prevent DVT. Massaging the legs daily (Choice D) can dislodge a blood clot, leading to serious complications in a client at risk for DVT.

Correct Answer: C

Rationale: Swelling of the fingers can indicate compromised circulation, which is a serious concern in a client with a new cast. It could suggest the development of compartment syndrome, a condition where increased pressure within the muscles can lead to impaired blood flow. This can result in tissue damage and should be addressed promptly. Itching under the cast, pain at the cast site, and warmth over the casted area are common findings after cast application and may not necessarily indicate an urgent issue requiring immediate reporting to the healthcare provider.

Correct Answer: D

Rationale: A low serum potassium level increases the risk of digoxin toxicity. Digoxin toxicity is more likely to occur in individuals with low potassium levels because potassium is crucial for proper heart function. A heart rate of 60 beats per minute, blood pressure of 120/80 mm Hg, and respiratory rate of 18 breaths per minute are within normal ranges and do not directly indicate an increased risk of digoxin toxicity.

Correct Answer: D

Rationale: The correct answer is to instruct the client to seek treatment for the sarcoma immediately. Ewing's sarcoma is an aggressive cancer, and prompt treatment is crucial for improving prognosis. Option A is incorrect because while pain management is important, addressing the underlying cause (sarcoma) is the priority. Option B is not as critical as seeking treatment for the sarcoma itself. Option C is not the most important instruction as the primary concern is addressing the cancer diagnosis.

Correct Answer: C

Rationale: Refraining from sexual intercourse helps prevent complications with partial placenta previa.
