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. For a patient on a ketogenic diet, which macronutrient is primarily increased?
- A. Carbohydrates
- B. Protein
- C. Fats
- D. Fiber
Correct answer: C
Rationale: The correct answer is C: Fats. A ketogenic diet is characterized by high fat intake, moderate protein intake, and very low carbohydrate intake. This diet aims to shift the body's metabolism to use fat as the primary source of energy instead of carbohydrates. Increasing fat intake while reducing carbohydrates is essential for achieving and maintaining a state of ketosis. Therefore, choices A, B, and D are incorrect as they do not align with the macronutrient adjustments required for a ketogenic diet.
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: Quit smoking
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. Which nursing diagnosis is a priority for clients with Borderline personality disorder?
- A. Risk for injury
- B. Ineffective individual coping
- C. Altered thought process
- D. Sensory perceptual alteration
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
5. What is the most common type of kidney stone?
- A. Cystine
- B. Calcium
- C. Struvite
- D. Uric acid
Correct answer: B
Rationale: The most common type of kidney stone is calcium-based, specifically calcium oxalate. This is usually due to high calcium levels in the urine, which can be caused by dietary factors or certain metabolic disorders. Cystine stones, on the other hand, are less common and occur in individuals with a hereditary disorder leading to excessive excretion of certain amino acids. Struvite stones are often formed in response to an infection. Uric acid stones may occur in individuals who do not consume sufficient fluids or who lose too much fluid, among other factors. Therefore, while all these substances can form stones in the kidneys, calcium stones are the most common.
