The nurse is reviewing the past medical history of a group of clients. Which client would the nurse suspect as having folic acid deficiency? The:

Choice A reason: Increasing the intake of dietary fiber is not related to the instruction for carvedilol. Dietary fiber is beneficial for lowering cholesterol and blood sugar levels, but it does not affect the action or side effects of carvedilol. The client should follow a balanced diet that is low in sodium, fat, and cholesterol.

Choice B reason: This is the correct answer. Changing from a lying to sitting position slowly is an important instruction for carvedilol. Carvedilol is a beta-blocker that lowers the blood pressure and the heart rate. It can cause orthostatic hypotension, which is a sudden drop in blood pressure when changing positions. This can lead to dizziness, fainting, or falls. The client should change positions gradually and avoid sudden movements.

Choice C reason: Expecting weight gain of 6-8 pounds is not an instruction for carvedilol. Weight gain is not a common or expected side effect of carvedilol. It can indicate fluid retention, which can worsen the heart condition and the blood pressure. The client should monitor their weight regularly and report any significant changes to the health care provider.

Choice D reason: Taking the medication after eating breakfast is not an instruction for carvedilol. Carvedilol can be taken with or without food, depending on the client's preference and tolerance. The important thing is to take the medication at the same time every day and not to skip or double the doses.

Choice A reason: This is incorrect. Traveling to cities where the oxygen level is lower, such as high-altitude areas, can trigger a sickle cell crisis by reducing the amount of oxygen in the blood. People with sickle cell anemia should avoid such places or take precautions such as using supplemental oxygen¹².

Choice B reason: This is incorrect. Strenuous exercise does not prevent sickle cell crisis, but rather can cause it by increasing the body's oxygen demand and dehydration. People with sickle cell anemia should avoid overexertion and rest frequently during physical activity¹³.

Choice C reason: This is incorrect. Flying on commercial airlines is not prohibited for people with sickle cell anemia, as long as they stay hydrated and avoid alcohol and caffeine. However, some people may need to use supplemental oxygen during flights, especially if they have a history of acute chest syndrome or pulmonary hypertension¹⁴.

Choice D reason: This is correct. Drinking plenty of fluids when outside in hot weather is important for people with sickle cell anemia, as dehydration can cause the red blood cells to sickle and block blood vessels. Staying hydrated can help prevent or reduce the severity of sickle cell crises¹⁵.
