1. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.

2. You are attending a certification on cardiopulmonary resuscitation (CPR) offered and required by the hospital employing you. This is

• A. professional course towards credits
• B. inservice education
• C. advance training
• D. continuing education

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.

3. How many diet-related major risk factors for coronary heart disease does Mrs. Winslow have?

• A. 1
• B. 4
• C. 2
• D. 3

Correct answer: B

Rationale: Mrs. Winslow has four major diet-related risk factors for coronary heart disease: high total cholesterol, high LDL cholesterol, high triglycerides, and low HDL cholesterol. Choice A is incorrect because there are more than one risk factor present. Choices C and D are incorrect as they do not account for the total number of diet-related major risk factors identified.

4. Electrolytes create _____, which is caused by water following electrolytes within or between cells.

• A. energy
• B. active transport
• C. passive diffusion
• D. osmotic pressure

Correct answer: D

Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.

5. 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.
