Nursing Elites

1. Churns chyme and has an environment of pH2; holds 4-6 cups of food:

• A. stomach
• B. pancreas
• C. large intestine
• D. small intestine

Correct answer: A

Rationale: The stomach churns food into chyme and has a highly acidic environment (pH 2) to aid in the digestion of proteins and other nutrients.

2. 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.

3. What type of drug is lamivudine, used for the management of HIV infection?

• A. CCR5 antagonist
• B. fusion inhibitor
• C. nucleoside reverse transcriptase inhibitor
• D. protease inhibitor

Correct answer: C

Rationale: Lamivudine belongs to the class of nucleoside reverse transcriptase inhibitors (NRTIs), making choice C the correct answer. NRTIs like lamivudine work by inhibiting the reverse transcriptase enzyme, an essential component for the HIV virus to replicate. Choices A, B, and D are incorrect because lamivudine does not function as a CCR5 antagonist, fusion inhibitor, or protease inhibitor in the management of HIV infection.

4. Nutritional goals for a patient wishing to modify eating patterns should adhere to each, except one. Which is the exception?

• A. Measurable
• B. Immediate
• C. Realistic
• D. Achievable

Correct answer: B

Rationale: Nutritional goals should be measurable, realistic, and achievable. They should not be immediate, as sustainable changes take time.

5. All of the following are electrolytes except:

• A. chloride
• B. potassium
• C. sodium
• D. iron

Correct answer: D

Rationale: Iron is not an electrolyte; electrolytes like sodium, potassium, and chloride help maintain fluid balance and are critical for nerve and muscle function.
