A patient's blood pressure (BP) reading is 142/91 mm Hg. How would the nurse classify the BP?
Normal.
Prehypertension.
Hypertension, stage 1.
Hypertension, stage 2.
The Correct Answer is C
Choice A rationale:
A normal blood pressure reading is typically around 120/80 mm Hg. The given reading of 142/91 mm Hg indicates elevated blood pressure.
Choice B rationale:
Prehypertension is defined as systolic blood pressure between 120-139 mm Hg or diastolic blood pressure between 80-89 mm Hg. The diastolic reading of 91 mm Hg places this patient in the stage 1 hypertension category.
Choice D rationale:
Hypertension, stage 2, is characterized by a systolic blood pressure of 140 mm Hg or higher and a diastolic blood pressure of 90 mm Hg or higher. While the systolic reading meets the criteria, the diastolic reading of 91 mm Hg falls into the stage 1 hypertension category.

Correct Answer is C
Explanation
Choice A rationale:
Enteric-coated iron is designed to be absorbed in the small intestine, not the stomach. Taking it with each meal might decrease its absorption due to interaction with food.
Choice B rationale:
Cobalamin (vitamin B12) deficiency can cause macrocytic anemia, not microcytic hypochromic anemia. Taking cobalamin with green, leafy vegetables does not address the specific iron deficiency seen in microcytic hypochromic anemia.
Choice C rationale:
Take the iron with orange juice 1 hour before meals is the correct answer. Vitamin C enhances the absorption of non-heme iron (the type of iron found in plant-based foods and iron supplements) by reducing it to a more absorbable form. Taking iron supplements with orange juice, which is high in vitamin C, can significantly improve iron absorption. Taking it before meals ensures better absorption due to reduced interaction with other dietary components.
Choice D rationale:
Decreasing the intake of antiseizure medications will not improve microcytic hypochromic anemia. Antiseizure medications do not directly influence iron absorption or the production of red blood cells.
Correct Answer is ["A","D"]
Explanation
Choice A rationale:
Eliminating excess H+ ions (hydrogen ions) is a primary mechanism the kidneys use to buffer acidosis. In acidosis, there is an excess of hydrogen ions in the body, leading to a decrease in pH. The kidneys help regulate the body's pH by excreting hydrogen ions to lower acidity.
Choice B rationale:
Excreting excess water is not a specific acid-base mechanism related to acidosis. While maintaining proper hydration is important for overall health, it does not directly influence the body's acid-base balance in the context of acidosis.
Choice C rationale:
Eliminating excess CO2 is primarily a respiratory mechanism, not a kidney function. CO2 elimination is more related to the lungs' ability to regulate the body's pH by adjusting respiratory rate and depth.
Choice D rationale:
Reabsorbing additional HCO3- ions (bicarbonate ions) is a renal mechanism to buffer acidosis. Bicarbonate ions act as a base and can neutralize excess hydrogen ions, raising the pH of the body fluids.
Choice E rationale:
Reabsorbing additional sodium ions is not a specific acid-base mechanism related to acidosis. While sodium ions are important for various physiological processes, they do not play a direct role in buffering acidosis.
