A nurse is providing teaching to a client who has a family history of hypertension. The nurse should inform the client that his blood pressure of 124/79 mm Hg places him in which of the following categories?

Elevated

Stage 1 hypertension

Stage 2 hypertension

Normal

Answer and Explanation

The Correct Answer is A

Choice A reason: A blood pressure reading of 124/79 mm Hg is considered elevated. The normal range for blood pressure is less than 120/80 mm Hg. Elevated blood pressure is when readings consistently range from 120129 systolic and less than 80 mm Hg diastolic.

Choice B reason: Stage 1 hypertension is defined by a systolic blood pressure ranging from 130 to 139 mm Hg or a diastolic pressure ranging from 80 to 89 mm Hg. The client's blood pressure does not fall into this category.

Choice C reason: Stage 2 hypertension is characterized by a systolic blood pressure of 140 mm Hg or higher or a diastolic pressure of 90 mm Hg or higher. The client's blood pressure is below these levels.

Choice D reason: A normal blood pressure reading is typically below 120/80 mm Hg. Although the client's diastolic pressure is within the normal range, the systolic pressure is above normal, thus it does not qualify as a normal blood pressure reading.

Correct Answer is C

Explanation

Choice A reason: The statement is incorrect because TSH does not attach to a protein in the blood; it stimulates the thyroid gland to produce thyroid hormones.

Choice B reason: This choice is partially correct. TSH does stimulate the thyroid gland, but the main purpose of the test is not to measure the 'feeding' of the gland but to assess its function and how well it's producing thyroid hormones.

Choice C reason: This is the correct statement. TSH levels are measured to determine the thyroid gland's activity, which directly influences the metabolic rate. The normal range for TSH levels in adults is typically 0.4 to 4.0 milliunits per liter (mU/L). However, these values can vary slightly based on the laboratory and the age of the individual.

Choice D reason: While TSH does influence energy levels by regulating thyroid hormone production, this choice does not directly explain the purpose of measuring TSH levels.

A. pH 7.30, HCO3 26 mEq/L, PaCO2 50 mm Hg B. pH 7.50, HCO3 20 mEq/L, PaCO2 32 mm Hg C. pH 7.55, HCO3 30 mEq/L, PaCO2 31 mm Hg D. pH 7.25, HCO3 19 mEq/L, PaCO2 30 mm Hg

Correct Answer is A

Explanation

Choice A reason: This set of values is indicative of metabolic acidosis with respiratory compensation, which is common in chronic kidney disease due to the accumulation of acids in the blood and the lungs' attempt to compensate by retaining CO2.

Choice B reason: This choice suggests respiratory alkalosis, which is less likely in chronic kidney disease unless there is a secondary respiratory condition causing hyperventilation.

Choice C reason: This choice indicates metabolic alkalosis, which is not typical for chronic kidney disease, as the kidneys are unable to excrete acid effectively.

Choice D reason: While this set of values does indicate acidosis, the expected compensatory response in chronic kidney disease would be an elevated PaCO2, not a normal or low value.
