1. Which physiologic role does vitamin C play in the body?

• A. Transcribing DNA to RNA
• B. Absorption and regulation of calcium
• C. Protects integrity of cellular membranes
• D. Catalyst for synthesis of blood-clotting factors

Correct answer: C

Rationale: Vitamin C plays a crucial role in protecting the integrity of cellular membranes. It is essential for collagen synthesis, which is important for wound healing and maintaining skin, blood vessels, and other tissues. Choice A is incorrect as the transcription of DNA to RNA is facilitated by vitamin A. Choice B is incorrect as calcium absorption and regulation are functions of vitamin D. Choice D is incorrect as vitamin K serves as a catalyst for the synthesis of blood-clotting factors, not vitamin C.

2. 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.

3. The ideal time to begin taking folate to prevent neural tube defects is:

• A. Before conception
• B. Once pregnancy begins
• C. At 6 weeks
• D. Upon completion of the first trimester

Correct answer: A

Rationale: Folate is crucial before conception to prevent neural tube defects. Neural tube development occurs early in pregnancy, often before a woman knows she is pregnant.

4. Which of the following is a good food source of iodine?

• A. Seafood
• B. Lettuce
• C. Broccoli
• D. Pork

Correct answer: A

Rationale: Seafood is a rich source of iodine, essential for maintaining healthy thyroid function and overall metabolic health. While lettuce, broccoli, and pork may contain some iodine, they do not provide as substantial an amount as seafood. Therefore, they are not considered 'good' sources of iodine in comparison.

5. Miss CEE is admitted for treatment of major depression. She appears withdrawn, disheveled, and states 'Nobody wants me'. What does the nurse most likely expect that Miss CEE is to be placed on?

• A. Neuroleptics medication
• B. Special diet
• C. Suicide precaution
• D. Anxiolytics medication

Correct answer: C

Rationale: Given Miss CEE's state of major depression and her expressed feelings of worthlessness ('Nobody wants me'), the nurse would most likely expect her to be placed on suicide precaution. This means that measures would be taken to ensure her safety and to prevent her from harming herself. While medications like neuroleptics (Choice A) and anxiolytics (Choice D) might be employed as part of her overall treatment, these medicines are primarily used for conditions like psychosis and anxiety respectively, not specifically for depression or suicidal ideation. A special diet (Choice B) may be part of a comprehensive treatment plan, but it is not as immediate or as directly related to her current emotional and psychological state as suicide precaution is.
