HESI CAT

Correct Answer: C

Rationale: The correct answer is C because a significant difference in calf circumference between the legs is a classic sign of DVT. This is due to the obstruction of blood flow in the deep veins of the leg, leading to swelling in the affected limb. Choices A, B, and D are not typical findings of DVT. Choice A describes a neurological response, choice B indicates a bruise on the right calf, and choice D describes pitting edema in both lower extremities, which are not specific signs of DVT.

Correct Answer: B

Rationale: The correct first action for a newborn potentially exposed to HIV is to bathe the infant with dilute chlorhexidine or soap. This helps reduce the risk of infection. Initiating treatment with zidovudine would be important but not the first priority. Measuring and recording the infant's frontal-occipital circumference and administering vitamin K are important tasks but are not the priority when dealing with potential HIV exposure. Immediate hygiene measures are crucial to minimize the risk of transmission.

Correct Answer: A

Rationale: The correct answer is to observe the PICC line site for inflammation. When a client with a PICC line develops a fever, it could indicate an infection related to the catheter. Assessing the PICC line site for signs of inflammation, such as redness, warmth, swelling, or drainage, is crucial in identifying a potential infection early. Choice B is incorrect because increasing fluid intake is not directly related to assessing a PICC line for infection. Choice C is not the most appropriate assessment in this situation as monitoring blood pressure may not directly help in identifying the cause of the fever. Choice D is unrelated to the assessment of a fever in a client with a PICC line.

Correct Answer: D

Rationale: The correct answer is D. A sudden absence of pain in a client with severe abdominal pain may indicate a serious condition such as internal bleeding. This sudden change in pain status requires immediate assessment to rule out any life-threatening complications. Choices A, B, and C do not indicate an acute change in the client's condition that would necessitate immediate attention compared to sudden pain relief in a client with severe abdominal pain.

Correct Answer: A

Rationale: The correct answer is A. Salty skin is a common sign of cystic fibrosis due to high levels of sodium in sweat. Asking about the taste of the child's skin provides valuable information related to the diagnosis of CF. Choices B, C, and D are not helpful in diagnosing cystic fibrosis. A musty odor in urine is not a typical symptom of CF. Drinking cow's milk or bowel movement frequency are not specific to CF diagnosis.
