1. High blood pressure is defined as systolic and diastolic measurements greater than or equal to:

A. 140 mm Hg and 90 mm Hg, respectively
B. 150 mm Hg and 80 mm Hg, respectively
C. 160 mm Hg and 110 mm Hg, respectively
D. 180 mm Hg and 120 mm Hg, respectively

Correct answer: A

Rationale: High blood pressure, or hypertension, is typically defined as having a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. Therefore, the correct answer is A. Choice B is incorrect because it suggests a higher systolic measurement than the standard definition. Choice C is incorrect as it provides an even higher systolic measurement and a much higher diastolic measurement. Choice D is also incorrect as it suggests extremely elevated blood pressure values, well above the typical definition of hypertension.

2. Which nutrient is critical for wound healing and immune function?

A. Vitamin B12
B. Vitamin C
C. Vitamin D
D. Vitamin K

Correct answer: B

Rationale: Vitamin C is essential for collagen formation and immune function.

3. Before administration of blood and blood products, the nurse should first:

A. Check with another R.N the clientâ€™s name, Identification number, ABO and RH type.
B. Explain the procedure to the client
C. Assess baseline vital signs of the client
D. Check for the BT order

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. What is a major feature of the therapeutic lifestyle changes (TLC) recommended for the treatment of high blood cholesterol?

A. Avoiding all foods that contain cholesterol
B. Reducing sodium intake to less than 2 g/day
C. Limiting total fat intake to less than 30% of energy intake
D. Limiting saturated fat intake to less than 7% of energy intake

Correct answer: D

Rationale: The correct answer is D, 'Limiting saturated fat intake to less than 7% of energy intake.' This is a central feature of the therapeutic lifestyle changes (TLC) recommended for treating high blood cholesterol. Saturated fats can increase low-density lipoprotein (LDL) cholesterol, a significant risk factor for heart disease. Choice A is incorrect because while it is recommended to limit cholesterol intake, it's not suggested to avoid all foods containing cholesterol entirely in the TLC. Choice B is also incorrect as although reducing sodium intake is beneficial for controlling blood pressure, it's not specifically targeted in the TLC for managing high cholesterol. Lastly, while limiting total fat intake is a healthy guideline, it's not as specific or effective as limiting saturated fat intake, making choice C also incorrect.
