1. How many amino acids are essential?

A. 5
B. 7
C. 9
D. 13

Correct answer: C

Rationale: The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.

2. During nutritional counseling, what is the most important step to take?

A. Consult the patient's family
B. Formulate a sample diet plan before presenting it to the patient
C. Include members of the dental team in the dietary formulation
D. Include the patient in the formulation of the dietary plan

Correct answer: D

Rationale: During nutritional counseling, the most important step is to include the patient in the formulation of the dietary plan. This ensures their active involvement, understanding, and commitment to the plan, leading to better compliance and success in achieving nutritional goals. Consulting the patient's family (Choice A) may be helpful but should not replace involving the patient directly. Formulating a sample diet plan before presenting it to the patient (Choice B) may not align with the patient's preferences or needs. Including members of the dental team in the dietary formulation (Choice C) may not be necessary unless specific dental concerns need to be addressed.

3. A nurse is preparing to administer a gavage feeding via a nasogastric tube to a preterm newborn who is receiving supplemental oxygen. Which of the following actions should the nurse take?

A. Stabilize the tube with tape to the newborn’s cheek.
B. Remove supplemental oxygen during the feeding.
C. Measure the stomach aspirate prior to the feeding.
D. Place the newborn on their left side for 30 minutes after the feeding.

Correct answer: C

Rationale: Measuring the stomach aspirate prior to the feeding is crucial to ensure the correct placement and function of the nasogastric tube. This step helps prevent complications such as aspiration or improper feeding. Choice A is incorrect as stabilizing the tube with tape to the newborn’s cheek can cause discomfort and skin irritation. Choice B is incorrect because removing supplemental oxygen during the feeding may compromise the newborn's respiratory status. Choice D is incorrect because placing the newborn on their left side for 30 minutes after the feeding is not a standard practice and is unnecessary for administering gavage feeding.

4. What nursing diagnosis would be most appropriate for a patient with heart failure?

A. risk for infection
B. fluid volume excess
C. impaired body temperature
D. ineffective airway clearance

Correct answer: B

Rationale: The most appropriate nursing diagnosis for a patient with heart failure is 'fluid volume excess.' In heart failure, the heart's reduced pumping ability leads to fluid retention, causing an excess of fluid in the body. This can result in symptoms such as edema, shortness of breath, and weight gain. 'Risk for infection,' 'impaired body temperature,' and 'ineffective airway clearance' are not the most appropriate nursing diagnoses for a patient with heart failure as they do not directly relate to the pathophysiology and common issues seen in heart failure patients.

5. In persons who are obese, weight reduction can improve such CHD risk factors as hypertension, blood lipid abnormalities, and?

A. inflammation
B. insulin resistance
C. gastrointestinal motility disorders
D. damage from cigarette smoking

Correct answer: B

Rationale: Weight reduction in obese individuals can improve insulin resistance, a key factor in reducing the risk of coronary heart disease and type 2 diabetes.
