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. Where is Vitamin E commonly found?

A. produced by bacteria in the GI tract
B. synthesized by the body through sunlight exposure
C. associated with beriberi deficiency
D. present in vegetable oils

Correct answer: D

Rationale: Vitamin E is an antioxidant commonly found in sources like vegetable oils, nuts, seeds, and green leafy vegetables. It plays a crucial role in protecting cells from damage. Choices A and B are incorrect as Vitamin E is not produced by bacteria in the GI tract nor synthesized by sunlight exposure. Choice C is incorrect as beriberi is a deficiency of Vitamin B1 (thiamine), not Vitamin E.

3. What is the purpose of the cuff in a Tracheostomy tube?

A. Separate the upper and lower airway
B. Separate trachea from the esophagus
C. Separate the larynx from the nasopharynx
D. Secure the placement of the tube

Correct answer: B

Rationale: The purpose of the cuff in a Tracheostomy tube is to separate the trachea from the esophagus. The cuff helps prevent aspiration by creating a seal that separates the trachea from the esophagus, reducing the risk of food or fluids entering the lungs. Choices A, C, and D are incorrect because the cuff's primary function in a Tracheostomy tube is to prevent aspiration rather than separating the upper and lower airway, larynx from the nasopharynx, or securing the placement of the tube.

4. A nurse is teaching a parent about appropriate snack choices for her 9-month-old infant. Which of the following food choices should the nurse recommend?

A. Skim milk
B. Unsalted popcorn
C. Graham crackers
D. Raw carrots

Correct answer: C

Rationale: Graham crackers are an appropriate snack choice for a 9-month-old infant due to their texture and ease of consumption. Skim milk (Choice A) is not recommended for infants under 1 year old due to the potential risk of developing milk allergies. Unsalted popcorn (Choice B) can be a choking hazard for infants. Raw carrots (Choice D) are a potential choking hazard for a 9-month-old infant and may be difficult for them to chew and digest.

5. The mechanism behind most CKD in patients without diabetes is mediated by:

A. enzyme systems
B. immune systems
C. catabolic systems
D. hormonal systems

Correct answer: B

Rationale: In non-diabetic patients, CKD is often mediated by immune system responses. Chronic inflammation triggered by immune system dysfunction can contribute to progressive kidney damage. Therefore, the correct answer is 'immune systems.' Choices A, C, and D are incorrect because CKD in non-diabetic patients is primarily associated with immune system abnormalities rather than enzyme, catabolic, or hormonal systems.
