Correct Answer: D

Rationale: The correct answer is D. New onset of tachypnea indicates a potential respiratory complication that requires immediate attention. Assessing the client with a hip fracture and tachypnea first is crucial to address the respiratory issue and prevent further deterioration. Choices A, B, and C do not present immediate life-threatening complications that require urgent assessment compared to a new onset of tachypnea.

Correct Answer: B

Rationale: The correct answer is B. The nurse should inform the client that their oncologist might prescribe a cold cap during treatment to reduce chemotherapy-induced hair loss by cooling the scalp. Choice A is incorrect as washing the hair during treatment is generally recommended. Choice C is incorrect as sunscreen is not typically needed for the scalp in this context. Choice D is incorrect as regrowth of hair can vary among individuals and is not guaranteed within a specific timeframe.

Correct Answer: A

Rationale: The correct answer is A: 'Sweating and trembling.' These are classic early signs of hypoglycemia in a diabetic patient. Sweating occurs due to the activation of the sympathetic nervous system in response to low blood sugar levels, while trembling is a result of the body's attempt to increase muscle activity to raise blood sugar levels. Confusion and irritability (Choice B) are more advanced signs of hypoglycemia that occur if the condition is not treated promptly. Dizziness and increased heart rate (Choice C) can also occur but are not as specific and early as sweating and trembling. Nausea and vomiting (Choice D) are more commonly associated with other conditions or severe hypoglycemia, rather than being early signs.

Correct Answer: B

Rationale: Abdominal cramping is a common manifestation of hyponatremia, as the sodium imbalance affects muscle function. Numbness of the extremities (Choice A) is more commonly associated with electrolyte imbalances such as hypocalcemia. Bradycardia (Choice C) is not typically a direct manifestation of hyponatremia. Positive Chvostek's sign (Choice D) is related to hypocalcemia, not hyponatremia.

Correct Answer: C

Rationale: Choice C is correct because it demonstrates the client's understanding of the procedure, which involves discarding the first urine of the day at the specified time and then saving all subsequent urine for the next 24 hours. Choices A, B, and D do not reflect an understanding of the correct procedure. Choice A is incorrect because bowel movements are not part of a 24-hour urine collection. Choice B is incorrect as it does not specify discarding the first urine. Choice D is incorrect as it mentions filling up the bottle quickly, which is not the correct way to collect a 24-hour urine sample.
