1. 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.

2. The RDA for iron is higher in premenopausal women than for men or postmenopausal women because of the blood loss during menstruation.

A. Both the statement and the reason are correct and related.
B. Both the statement and the reason are correct but are not related.
C. The statement is correct, but the reason is not correct.
D. The statement is not correct, but the reason is correct.

Correct answer: A

Rationale: Both the statement and the reason are correct and related. The Institute of Medicine (IOM) recommends 18 mg of iron per day for women 19 to 50 years old, 8 mg/day for women 51 years old and older, and men 19 years old and older. During menstruation, women lose blood containing iron, leading to a higher iron requirement in premenopausal women compared to men or postmenopausal women. This increased demand aims to replenish the iron lost during this physiological process. Therefore, the statement and reason are directly linked, explaining why the RDA for iron is higher in premenopausal women than in men or postmenopausal women. Choices B, C, and D are incorrect as they do not accurately assess the relationship between the statement and the reason provided in the question.

3. A Hazard Analysis and Critical Control Points (HACCP) program would address which element of food service?

A. cleaning and disinfecting of utensils
B. developing healthy menus
C. controlling patient calorie intake
D. prescribing diets for patients with swallowing problems

Correct answer: A

Rationale: The correct answer is A. Hazard Analysis and Critical Control Points (HACCP) programs are designed to ensure food safety by identifying and controlling potential hazards. This includes addressing the cleaning and disinfecting of utensils to prevent contamination and maintain safe food handling practices. Choices B, C, and D are incorrect because HACCP primarily focuses on preventing food safety hazards rather than developing menus, controlling calorie intake, or prescribing diets for specific medical conditions.

4. When is infertility said to exist?

A. When a woman has no uterus
B. When a woman has no children
C. When a couple has been trying to conceive for 1 year without success
D. When a couple has desired a child for 6 months

Correct answer: C

Rationale: Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most couples. Therefore, the correct answer is C. A, B, and D are incorrect. While having no uterus (choice A) may result in infertility, it is not the sole determining factor. Similarly, not having children (choice B) does not automatically indicate infertility. Lastly, the time frame of 6 months (choice D) is not sufficient to determine infertility; typically, a year of trying without success is required for such a diagnosis.

5. An emerging technique in screening for Breast Cancer in developing countries like the Philippines is:

A. Mammography once a year starting at the age of 50
B. Clinical BSE Once a year
C. BSE Once a month
D. Pap smear starting at the age of 18 or earlier if sexually active

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
