1. Diego is undergoing blood transfusion of the first unit. The earliest signs of transfusion reactions are:

• A. Oliguria and jaundice
• B. Urticaria and wheezing
• C. Headache, chills, & fever
• D. Hypertension and flushing

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

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. Can fluid retention cause lab values to be deceptively high, whereas dehydration may cause the values to be deceptively low?

• A. TRUE
• B. FALSE
• C. Not always
• D. Sometimes

Correct answer: B

Rationale: The statement is incorrect. Fluid retention generally results in lab values appearing deceptively low, not high, because the excess fluid dilutes the concentration of substances in the blood. Conversely, dehydration can make lab values appear deceptively high as the reduced fluid volume in the body means substances in the blood are less diluted. Choices 'C: Not always' and 'D: Sometimes' are not specific and do not directly address the statement in the question, hence they are incorrect.

4. Which two dietary components may help decrease blood cholesterol levels?

• A. Omega-3 fatty acids and soluble fiber
• B. Short-chain fatty acids and insoluble fiber
• C. Trans fatty acids and potassium
• D. Cis fatty acids and calcium

Correct answer: A

Rationale: The correct answer is A: Omega-3 fatty acids and soluble fiber. Omega-3 fatty acids are known to reduce triglycerides, while soluble fiber helps to lower LDL cholesterol levels. Both of these components are beneficial in managing blood cholesterol levels. Choice B, short-chain fatty acids and insoluble fiber, is incorrect as they do not have the same cholesterol-lowering effects as omega-3 fatty acids and soluble fiber. Choice C, trans fatty acids and potassium, is incorrect as trans fatty acids can raise LDL cholesterol levels and increase the risk of heart disease. Choice D, cis fatty acids and calcium, is incorrect as cis fatty acids are common in natural fats and do not specifically help in reducing blood cholesterol levels.

5. Which of the following amino acids are considered indispensable?

• A. Lysine
• B. Methionine
• C. Tryptophan
• D. Valine

Correct answer: A

Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.
