Correct Answer: D

Rationale: Huntington's chorea is characterized by writhing, twisting movements of the face and limbs, known as chorea. This disorder is caused by a genetic mutation affecting specific brain cells. Epilepsy presents with seizures, Parkinson's with tremors and rigidity, and multiple sclerosis with central nervous system issues. The specific description of writhing and twisting movements aligns with Huntington's chorea, making it the correct answer. Choices A, B, and C are incorrect as they describe different neurological disorders with distinct symptoms that do not match the writhing, twisting movements characteristic of Huntington's chorea.

Correct Answer: C

Rationale: In an obstetrical emergency, the immediate action the nurse should take after the baby delivers is to suction the baby's mouth and nose to ensure the infant can breathe properly. This helps clear any potential obstructions and establish a clear airway. Cutting the umbilical cord (Choice B) and wrapping the baby in a clean blanket (Choice D) are important steps but should come after ensuring the baby's airway is clear. Placing extra padding under the mother (Choice A) is not a priority in this emergency situation as the focus should be on the baby's immediate needs for breathing and airway clearance.

Correct Answer: A

Rationale: When an elderly client with cancer is receiving NSAID therapy, monitoring BUN (blood urea nitrogen) and creatinine levels is crucial. NSAIDs can cause renal toxicity, especially in the elderly. BUN and creatinine levels help assess renal function and detect early signs of renal impairment. Monitoring creatinine alone (Choice B) is not sufficient as BUN provides complementary information about renal function. Monitoring hemoglobin (Hgb) and hematocrit (Hct) (Choice C) is important for assessing anemia but not specific to NSAID therapy in the elderly. CFT (Choice D) is not a standard abbreviation in this context, and monitoring coagulation function is not directly related to NSAID therapy in this scenario.

Correct Answer: C

Rationale: The correct answer is '"I should lay him on his back during a seizure."?' When a client is having a seizure, it is crucial to turn them onto their side to prevent aspiration of secretions. Placing them on their back can lead to potential airway compromise. Choices A, B, and D are correct statements that indicate a good understanding of caring for a child with a seizure disorder: ensuring rest, getting a medical alert bracelet for identification, and loosening clothing to facilitate breathing during a seizure.

Correct Answer: A

Rationale: The correct answer is high HDL cholesterol. High HDL cholesterol levels are associated with a decreased risk of cardiovascular disease because HDL helps remove LDL cholesterol from the arteries, reducing plaque buildup. Low HDL cholesterol (choice B) is actually associated with an increased risk of cardiovascular disease. Low total cholesterol (choice C) or low triglycerides (choice D) are not indicators of a decreased risk of cardiovascular disease; in fact, extremely low total cholesterol levels may indicate other health issues.
