Nursing Elites

1. This vaccine content is derived from RNA recombinants.

• A. Measles C. Hepatitis B vaccines
• B. Tetanus toxoids D. DPT
• C.
• D.

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

2. While the client has a pulse oximeter on his fingertip, you notice that sunlight is shining on the area where the oximeter is. Your action will be to:

• A. Set and turn on the alarm of the oximeter
• B. Do nothing since there is no identified problem
• C. Cover the fingertip sensor with a towel or bedsheet
• D. Change the location of the sensor every four hours

Correct answer: B

Rationale: In this scenario, the correct action is to do nothing since there is no identified problem with the sunlight shining on the area where the oximeter is placed. The functionality of the oximeter is not affected by sunlight, so covering it or changing its location unnecessarily could disrupt the monitoring process. Setting the alarm or changing the sensor location every four hours is not indicated in this situation and may lead to unnecessary interventions. It's essential to assess the situation carefully and intervene only when necessary, ensuring that care provided is appropriate and effective.

3. Each statement is true of calcium within saliva, except one. Which is the exception?

• A. Saliva is supersaturated with calcium.
• B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
• C. Calcium and phosphate in saliva provide a buffering action.
• D. Calcium within saliva increases dental caries.

Correct answer: D

Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.

4. Which of the following groups of vitamins are fat-soluble?

• A. vitamins B and C
• B. vitamins A and C
• C. vitamins B, E, K, D
• D. vitamins A, E, K, D

Correct answer: D

Rationale: The correct answer is D: vitamins A, E, K, and D. Fat-soluble vitamins are absorbed along with fats in the diet and can be stored in the body's fatty tissue. Vitamins B and C are water-soluble vitamins and are not stored in the body; any excess amounts are usually excreted in the urine. Therefore, choices A, B, and C are incorrect.

5. When assessing for criteria that signify malnutrition risk, which element would most likely be included as part of the functional assessment data?

• A. severity of illness
• B. presence of pressure sores
• C. localized edema
• D. generalized weakness

Correct answer: D

Rationale: Generalized weakness is a key indicator of malnutrition and is often assessed as part of functional status, reflecting muscle wasting and reduced physical function. The other choices, such as severity of illness, presence of pressure sores, and localized edema, are important factors to consider in a clinical assessment but are not primarily indicative of malnutrition risk. Generalized weakness directly relates to the functional impact of malnutrition on physical performance.
