Nursing Elites

1. Which enzyme is most essential for hydrolyzing large protein molecules?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.

2. The equal sharing of resources is known as _____.

• A. autonomy
• B. ethics
• C. disclosure
• D. distributive justice

Correct answer: D

Rationale: The correct answer is D, distributive justice. Distributive justice involves the fair and equitable distribution of resources among all individuals in society. Option A, autonomy, refers to the right of individuals to make their own decisions. Option B, ethics, pertains to moral principles. Option C, disclosure, refers to the act of making information known.

3. What should Mrs. Smith do to increase her HDL levels, as advised by the nurse?

• A. Monitor her blood glucose levels
• B. Quit smoking
• C. Control her blood pressure
• D. Take fish oil supplements

Correct answer: B

Rationale: The correct answer is 'Quit smoking.' Smoking has been shown to lower HDL (High-Density Lipoprotein) levels, and quitting can help to improve these levels. HDL is often referred to as 'good cholesterol' because it helps to remove other forms of cholesterol from the bloodstream, reducing the risk of heart disease. While monitoring blood glucose levels, controlling blood pressure, and taking fish oil supplements can contribute to overall health and wellbeing, they do not directly increase HDL levels in the same way that quitting smoking does. Therefore, quitting smoking is the most effective way for Mrs. Smith to increase her HDL levels as advised by the nurse.

4. 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.

5. What is the first step in decontamination?

• A. Immediately applying a chemical decontamination foam to the area of contamination
• B. Thoroughly washing and rinsing the patient with soap and water
• C. Immediately applying personal protective equipment
• D. Removing the patient's clothing and jewelry, then rinsing the patient with water

Correct answer: D

Rationale: The correct first step in decontamination is to remove the patient's clothing and jewelry to prevent further exposure and then rinse the patient with water. This helps to eliminate any contaminants on the patient's body. Choice A is incorrect because applying a chemical decontamination foam should come after removing clothing. Choice B is incorrect as washing and rinsing the patient should follow the removal of clothing. Choice C is incorrect as personal protective equipment should be worn by the individual performing the decontamination, not applied to the patient.
