Correct Answer: B

Rationale: The correct answer is B: Pain for 3 consecutive months. Recurrent abdominal pain (RAP) is characterized by abdominal pain that occurs at least once per week for at least 2 months before diagnosis. Choosing option A is incorrect since morning headaches are not a common characteristic of RAP. Option C is incorrect because febrile episodes in the late afternoon are not typically associated with RAP. Option D is incorrect as diaphoresis (excessive sweating) when attacks occur is not a common finding in RAP.

Correct Answer: D

Rationale: The most important instruction for the nurse to include in the discharge teaching for a client with COPD receiving home oxygen therapy is to ensure the oxygen tank is stored in a secure upright position. This is crucial to prevent accidents such as leaks or falls that can lead to serious injury or damage. Choice A is incorrect as increasing the oxygen flow rate during physical activity without a healthcare provider's guidance can be harmful. Choice B is incorrect as smoking near an oxygen source can cause a fire hazard. Choice C is incorrect as petroleum jelly is flammable and should not be used around oxygen due to the risk of combustion.

Correct Answer: A

Rationale: The correct answer is A. When caring for a client with Meniere's disease, the highest priority nursing problem is the potential for injury related to vertigo. Meniere's disease is characterized by symptoms like vertigo, which can increase the risk of falls and injuries. Ensuring the client's safety and preventing falls take precedence over other concerns. Choices B, C, and D are not the highest priority because they do not directly address the immediate risk of harm associated with vertigo and falls.

Correct Answer: A

Rationale: The correct answer is A: 'Report any signs of a sore throat or fever immediately.' Phenytoin can cause blood dyscrasias, which can manifest as a sore throat or fever. These symptoms could indicate a serious side effect that requires immediate medical attention. Choice B is incorrect because phenytoin should not be taken with antacids as they can decrease its absorption. Choice C is incorrect because discontinuing phenytoin abruptly can lead to rebound seizures; drowsiness is a common side effect that may improve with time. Choice D is incorrect because adjusting the dosage of phenytoin should only be done under healthcare provider supervision, not based on experiencing an aura.

Correct Answer: B

Rationale: A weight gain of 6.6 pounds is approximately equivalent to 3 liters of fluid. It is important to remember that 1 liter of fluid is equal to 1 kg, which is approximately 2.2 pounds. Therefore, when the client gains 6.6 pounds, it translates to 3 liters of fluid. Choices A, C, and D are incorrect as they do not align with the conversion rate of 1 liter of fluid to 2.2 pounds.
