Nursing Elites

1. Which enzyme is most essential for the digestion of triglycerides found in butterfat?

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

Correct answer: A

Rationale: The correct answer is A: Gastric lipase. Gastric lipase is crucial for the digestion of short- and medium-chain triglycerides, such as those found in butterfat. Pepsin is involved in protein digestion, not lipid digestion. Mucus acts as a protective barrier in the stomach and does not play a direct role in lipid digestion. Intrinsic factor is involved in the absorption of vitamin B12 and is not related to the digestion of triglycerides.

2. A condition that often progresses to become type 2 diabetes mellitus is:

• A. type 1 diabetes mellitus
• B. high blood pressure
• C. chronic pancreatitis
• D. impaired glucose tolerance

Correct answer: D

Rationale: Impaired glucose tolerance is a pre-diabetic state characterized by higher than normal blood sugar levels. It is often associated with insulin resistance and can progress to type 2 diabetes mellitus. Type 1 diabetes mellitus (Choice A) is an autoimmune condition where the body attacks insulin-producing cells, leading to a lack of insulin production. High blood pressure (Choice B) and chronic pancreatitis (Choice C) are not directly linked to the progression to type 2 diabetes mellitus.

3. A nurse is teaching a group of clients about stress. Which of the following should the nurse include in the teaching?

• A. Protein requirements decrease in times of stress.
• B. Acute stress causes an increase in metabolism.
• C. Stress causes a positive nitrogen balance in the body.
• D. Glucose is broken down more slowly during times of stress.

Correct answer: B

Rationale: The correct answer is B: Acute stress causes an increase in metabolism. During acute stress, the body's fight-or-flight response is activated, leading to an increase in metabolism to provide energy for the body to respond to the stressor. Choices A, C, and D are incorrect. Protein requirements actually increase during times of stress to support the body's needs. Stress typically leads to a negative nitrogen balance in the body, not a positive one. Glucose is broken down more rapidly, not slowly, during times of stress to provide immediate energy.

4. A client with pre-dialysis end-stage kidney disease is being taught about diet. Which of the following instructions should the nurse include?

• A. Increase intake of dietary phosphorus.
• B. Eliminate foods high in protein from your diet.
• C. Reduce intake of foods high in potassium.
• D. Increase intake of sodium-containing foods.

Correct answer: C

Rationale: In pre-dialysis end-stage kidney disease, reducing intake of foods high in potassium is crucial as impaired kidney function can lead to potassium buildup in the blood, which can be dangerous. High potassium levels can cause irregular heartbeats and even cardiac arrest. Therefore, advising the client to reduce potassium-rich foods is essential to prevent complications. Choices A, B, and D are incorrect. Increasing dietary phosphorus, eliminating foods high in protein, or increasing sodium-containing foods are not appropriate recommendations for a client with pre-dialysis end-stage kidney disease as they can exacerbate the condition.

5. Which physiologic effect should the nurse expect in a client addicted to hallucinogens?

• A. Dilated pupils
• B. Constricted pupils
• C. Bradycardia
• D. Bradypnea

Correct answer: B

Rationale: Clients addicted to hallucinogens often exhibit constricted pupils due to the effects of the drug on the sympathetic nervous system. This sympathetic stimulation causes the pupils to constrict rather than dilate. Choices A, C, and D are incorrect. Dilated pupils are more commonly associated with stimulant use, while bradycardia (slow heart rate) and bradypnea (slow breathing) are not typical effects of hallucinogens.
