1. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?

• A. hemoglobin
• B. transferrin
• C. myoglobin
• D. hepcidin

Correct answer: A

Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.

2. A Hazard Analysis and Critical Control Points (HACCP) program would address which element of food service?

• A. cleaning and disinfecting of utensils
• B. developing healthy menus
• C. controlling patient calorie intake
• D. prescribing diets for patients with swallowing problems

Correct answer: A

Rationale: The correct answer is A. Hazard Analysis and Critical Control Points (HACCP) programs are designed to ensure food safety by identifying and controlling potential hazards. This includes addressing the cleaning and disinfecting of utensils to prevent contamination and maintain safe food handling practices. Choices B, C, and D are incorrect because HACCP primarily focuses on preventing food safety hazards rather than developing menus, controlling calorie intake, or prescribing diets for specific medical conditions.

3. Patients maintained using peritoneal dialysis may gain weight because:

• A. their appetite is increased
• B. physical activity is limited
• C. they absorb glucose from the dialysate
• D. they absorb amino acids from the dialysate

Correct answer: C

Rationale: Glucose from the peritoneal dialysis solution can be absorbed into the bloodstream, leading to weight gain if not balanced with diet and activity.

4. In obtaining a urine specimen for culture and sensitivity on a catheterized patient, the nurse is correct if:

• A. Clamp the catheter for 30 minutes, Alcoholize the tube above the clamp site, Obtain a sterile syringe and draw the
• B. Alcoholize the self sealing port, obtain a sterile syringe and draw the specimen on the self sealing port
• C. Disconnect the drainage bag, obtain a sterile syringe and draw the specimen from the drainage bag
• D. Disconnect the tube, obtain a sterile syringe and draw the specimen from the tube

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

5. Of the foods listed, the best source of phosphorus is?

• A. lettuce
• B. pears
• C. chicken
• D. noodles

Correct answer: C
