Nursing Elites

1. The oral cavity is the site of a wide variety of systemic disease manifestations due to:

• A. Rapid cellular turnover
• B. Constant attack by microorganisms
• C. Trauma-intense environment
• D. All of the above

Correct answer: D

Rationale: The oral cavity is indeed the site of various systemic disease manifestations due to multiple factors. Firstly, the rapid cellular turnover in the oral mucosa makes it susceptible to diseases. Secondly, the constant presence of microorganisms in the oral cavity contributes to the development of systemic diseases. Finally, the oral cavity being a trauma-intense environment further increases the risk of systemic manifestations. Therefore, all the provided options - rapid cellular turnover, constant attack by microorganisms, and a trauma-intense environment - play a role in making the oral cavity a site for various systemic diseases. Hence, the correct answer is 'All of the above.' Choices A, B, and C are incorrect individually as they each represent only one aspect of why the oral cavity is prone to systemic disease manifestations, whereas the correct answer encompasses all these factors.

2. A nurse is caring for a client who is to receive a mechanically altered diet. Which of the following client food choices necessitates intervention by the nurse?

• A. Scrambled eggs
• B. Cottage cheese
• C. Piece of wheat toast
• D. Sliced banana

Correct answer: D

Rationale: The correct answer is 'Sliced banana.' A mechanically altered diet is designed for clients who have difficulty chewing or swallowing. Sliced bananas, due to their texture and potential choking hazard for clients with swallowing difficulties, would necessitate intervention by the nurse. Scrambled eggs, cottage cheese, and a piece of wheat toast are softer and safer options for clients on a mechanically altered diet, making them appropriate choices.

3. Which of the following methods is the best method for determining nasogastric tube placement in the stomach?

• A. X-ray
• B. Observation of gastric aspirate
• C. Testing of pH of gastric aspirate
• D. Placement of external end of tube under water

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

4. Why does Anita stand in front of the mirror while performing a Breast Self-Examination (BSE)?

• A. To check for unusual discharges from the breast
• B. To check for any obvious malignancy
• C. To observe the size and contour of the breast
• D. To check for thickness and lumps in the breast

Correct answer: C

Rationale: When performing a Breast Self-Examination (BSE), one of the reasons for standing in front of a mirror is to observe the size and contour of the breast (Choice C). This helps in identifying any visible changes or abnormalities such as dimpling, puckering, or changes in the size and shape of the breasts. While unusual discharges (Choice A) and thickness or lumps (Choice D) can be part of the changes a person might notice during a BSE, these are typically identified by palpation or by squeezing the nipple for discharge, not by just looking in the mirror. Choice B, checking for obvious malignancy, is too vague and not specific enough as malignancy is often not visible to the naked eye.

5. How many amino acids are essential?

• A. 5
• B. 7
• C. 9
• D. 13

Correct answer: C

Rationale: The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.
