Nursing Elites

1. When performing endotracheal suctioning, the nurse applies suctioning while withdrawing and gently rotating the catheter 360 degrees for which of the following time periods?

• A. 10-15 seconds
• B. 30-35 seconds
• C. 20-25 seconds
• D. 0-5 seconds

Correct answer: D

Rationale: During endotracheal suctioning, the nurse should apply suctioning while withdrawing and gently rotating the catheter 360 degrees for a short period of 0-5 seconds. This brief duration helps minimize the risk of hypoxia and trauma to the airway. Choices A, B, and C suggest longer time periods for suctioning, which can increase the risk of complications such as hypoxia, mucosal damage, and the removal of excess amounts of airway secretions.

2. Generally, lifestyle-related diseases share common risk factors. Which of the following is NOT one of them?

• A. Physical activity
• B. Smoking
• C. Genetics
• D. Nutrition

Correct answer: C

Rationale: Common risk factors for lifestyle-related diseases typically include aspects of one's lifestyle that can be modified or controlled, such as physical activity, smoking habits, and nutrition. These factors can be changed to prevent or manage lifestyle-related diseases. Genetics, on the other hand, is not a modifiable risk factor, meaning it cannot be changed or controlled. Therefore, it is not considered a common risk factor for lifestyle-related diseases. Understanding the modifiable risk factors for these diseases allows for better prevention and management strategies, and helps reduce the risk of complications.

3. Which item is typically fortified with iodine to address iodine deficiency in the population?

• A. Flour
• B. Salt
• C. Canned vegetables
• D. Drinking water

Correct answer: B

Rationale: Iodized salt is the correct answer. Iodine deficiency can lead to thyroid problems, so iodine is added to salt to ensure an adequate intake of this essential nutrient. Flour is often fortified with other nutrients like folic acid, iron, and niacin, but not iodine. Canned vegetables and drinking water are not typically fortified with iodine to address deficiency in the population.

4. Which of the following is not true about Pure Experimental research?

• A. There is a control group
• B. There is an experimental group
• C. Selection of subjects in the control group is randomized
• D. There is a careful selection of subjects in the experimental group

Correct answer: D

Rationale: In Pure Experimental research, subjects in the experimental group are typically selected randomly to minimize bias and ensure that the results are attributable to the intervention being studied. Therefore, the statement 'There is a careful selection of subjects in the experimental group' is not true. This careful selection would introduce bias and compromise the validity of the experimental results. Choices A, B, and C are true for Pure Experimental research as it involves both a control group, an experimental group, and randomization of subject selection in the control group to ensure comparability.

5. Which type of lipid is solid at room temperature?

• A. Cholesterol
• B. Phospholipid
• C. Saturated fat
• D. Trans fat

Correct answer: C

Rationale: Saturated fats, such as those found in butter and lard, are typically solid at room temperature due to the lack of double bonds, which allows the fat molecules to pack closely together. Cholesterol (Choice A) is a steroid, not a fat, and while it's solid at room temperature, it doesn't fit the general category of 'lipid' in the context of this question. Phospholipids (Choice B) are a major component of all cell membranes and can be both solid and liquid at room temperature depending on their composition. Trans fats (Choice D) can also be solid or liquid at room temperature, but they are not typically referred to as 'lipids' in a general sense.
